Generations of Computer 1st to 5th Explained with Pictures.

The history of computer technology is often used to refer to the origin of all the different generations of computers . From first to fifth each computer generation is characterized by significant technological development in their components, memory , and elements which essentially changed the way these devices work.

Several periods of generation from over the years advanced the technological evolution leads to the creation of today’s modern computer with more complex, more powerful, and increased capability and functionality.

Introduction to Computer Generations

This development period of electronic computing technology is called Computer Generation. There are five generations of computers identified, although the sixth generation could be in development now in the early 21st century.

During the evolutionary timeline, each generation of computers has improved a lot by undergoing considerable changes in their size, type, and functionality.

By analyzing them, one can trace the evolution of computer technology, to see how the computer industry has changed over the years and how great capabilities and software progress has been made by humankind in under a hundred years , as a result, the creation of different generations.

At present, the computer is playing a significant part in human existence because today’s digital computer is being used for every work in each field. If someday an issue occurs in the computer or the server is down, at that point all the work stops. This is how significant it is for technology development!

In this article, I will introduce you to all the generations of computers with pictures by explaining the complete information about their characteristics , names, components , and examples too.

Generations of Computer From 1st to 5th

Let’s discover the series of computer generations in the following list:

1st Generation of Computer (1940-1956)

This first generation of computers was based on vacuum tube technology used for calculations, storage, and control, invented in 1904 by John Ambrose Fleming. The vacuum tubes and diode valves were the chief components of the first generations of computers.

First-generation computers relied on the lowest-level machine language, in order to perform operations, and could only solve a single problem at a point of time.

Magnetic drums were used as the memory in these computers (were very slow in speed). The punched and magnetic tapes were used for the input and output function of the computer in order to display on prints even the results weren’t 100% accurate.

Also, the first generation of computers available was based on the 8-bit microprocessor.

The disadvantages of 1st gen computers are that they were very enormous in size and heavy in weight (made of thousands of vacuum tubes ) , occupying large rooms. Also, once they were kept in one place it was difficult to transfer. Another con like using a decimal number system and many switches and cables.

In addition, they were also very expensive to operate with using a large amount of electricity, the vacuum tubes produced large amounts of heat, so an air conditioner was required for the proper functioning unless a lot of heat can cause a malfunction.

The advantage of the first generation of computers is that they could calculate in milliseconds (about five thousand sums per second.)

The computers of first-generation were managed to use in different fields like weather forecasting, solving mathematical problems, energy tasks, also in space research, military, and other scientific tasks.

In the first generation of computers, the first computer of the world named “ENIAC” (Electronic Numerical Integrator and Computer) was discovered by John Mauchly and J. Presper Eckert in the year between 1943 to 1945.

ENIAC used panel-to-panel wiring and switches for programming, occupied more than 1,000 square feet, used about 18,000 vacuum tubes, and weighed 30 tons.

Characteristics of the 1st Generation of Computer:

Vacuum tubes and diode valves were used as the main electronic component in the first generation computers.
Punch cards, paper tape utilized for input and output operations.
Magnetic drums used for storage.
Huge in size and weight with a lot of power consumption.
Very expensive in price also not reliable.
Computers were programmed with low-level machine language also has low operating speed.

Examples of the first generation of computers are ENIAC (Electronic Numerical Integrator and Computer), UNIVAC (Universal Automatic Computer) EDSEC (Electronic Delay Storage Automatic Calculator), EDVAC (Electronic Discrete Variable Automatic Computer), (Electronic delay storage automatic calculator), IBM -701 and IBM 650.

ENIAC, the first general-purpose electronic digital computer . This computer about 18,000 vacuum tubes used for the calculation result in huge in size, occupied more than 1,000 square feet, and weighed 30 tons. These were the harbingers of today’s digital computers. This first computing machine was designed by people J. P. Eckert, W. Mosley, J. W. Mauchly.

2nd Generation of Computer (1956-1964)

The second generation of computers replaced the vacuum tubes with a reliable component called transistors for manufacturing of computers was invented by William Shockley in 1947.

The transistors were the revolution in the computer field because this component advantaged the 2nd gen computer by increasing the performance, operating speed (hundreds of thousands of operations per second), as well as decreasing the electricity consumption of the computers.

Transistors were far superior to the vacuum tube, allowing computers to get faster, cheaper, more energy-efficient made and possible to reduce the size of computing equipment and ultimately heat reduced and reliability improved.

Computers of second-generation are characterized by the use of the first high-level programming languages, allowing programmers to specify instructions in words. At this time, early versions of COBOL, ALGOL, SNOBOL, and FORTRAN languages were developed .

These were the first computers to store their instructions in their memory, which went from a magnetic drum to magnetic core technology. During this period, the first computer game name “ Spacewar ” was seen on a PDP-1 computer.

Do you know~ that the oldest abacus was a computing machine designed to calculate thousands of years ago, which is still used in schools today to do calculations.

Also, the concept of Central Processing Unit (CPU), multi-programming operating systems, programming language, memory, and input and output units (I / O units) were developed in the timeline of second-generation computers.

The major disadvantages of Second-generation computers were they still relied on punch cards for input and hard copies for output as well as still it was difficult to move the computers for the reason they were enough large and even some computers needed ACs.

2nd generation of computers still huge in size

This second generation of computers was first used in the fields like the atomic energy industry and nuclear power plants and other commercial fields.

Characteristics of the 2nd Generation of Computer:

Computers based on transistors instead of vacuum tubes.
Magnetic Tape was used to store data.
Relatively small in size and reduced weight with low energy consumption than 1st gen computers.
Faster, reliable, and less expensive than the first generation.
Use of storage devices, printers, and operating systems, etc.
Higher-level languages like COBOL, ALGOL, SNOBOL, and FORTRAN were developed and used.

Examples of the second generation of computers include IBM 1620, CDC 1604, IBM 7094, UNIVAC 1108, IBM 620, CDC 3600, IBM 4044, Honeywell 400, IBM 1401 Mainframe, and PDP-1 minicomputer. IBM was actively working, producing transistor versions of its computers.

3rd Generation of Computer (1964-1971)

The third generation appeared in the form of integrated circuits (invented by Jack Kilby from 1958 to 1964). An IC (integrated circuit) is consists of many small transistors mounted on chips , which are called semiconductors.

This synchronized chip became an important foundation for the third generation computers when scientists combined hundreds of transistors fit in this circuit result in a more powerful electronic segment called an integrated circuit.

Multiprogramming was implemented (this is when there are several executable programs in memory) at the same time that it diminished their manufacturing costs. In the mid-60s. IBM improved the term “computer architecture”. By the end of the 60s. mini-computers appeared.

This revolutionary innovation allowed to expansion of the processing capacity and memory of the machines.

Instead of punch cards and prints, users interacted via keyboards and monitors , and interacted with an operating system, allowing the device to run various applications at once with a central program that monitored the memory.

As you can see, the first appearance of computer monitors fell on the second generation of computers. The invention belongs to the company IBM, which in 1964 released the commercial display station IBM-2250.

it was used in the system/360 series. The model had a vector monochrome display measuring 12×12 inches, with a resolution of 1024×1024 pixels and a refresh rate of 40 Hz. This invention revolutionized today’s different types of monitors including LCD, LED, OLED monitors.

The invention of IC incredibly decreased the size of computers and made it easy for transportation from one place to another. The working speed and efficiency of this generation of computers were much faster than the previous generation and even cheaper.

High-end languages such as PASCAL, BASIC, FORTRAN – II TO IV, COBOL, ALGOL developed in this generation.

For the first time, they got access to a mass audience allowed computers to penetrate into different spheres of human activity since they were smaller and cheaper. Along these, they turned out to be more specialized (i.e., there were different computers for different tasks).

The 3rd generation of computers was the initial move towards the miniaturization of computers and quickly expanded their scope: control, automation of scientific experiments, data transmission, etc. In addition to being used in the manufacture of radios, TVs, and other similar devices .

Characteristics of the 3rd Generation of Computer:

In this generation, computers based on Integrated Circuit was more powerful than the transistor.
The size of the computers was likewise little because the size of the IC being more modest than the circuit size of the transistors.
More reliable, inexpensive, faster, energy-efficient, as well as very light in weight than 2nd gen computers.
The first Computer Mouse and Keyboard were appeared and used in the 3rd generation of computers
Use of new versions of high-level languages like BASIC, COBOL, FORTRAN, PASCAL, and ALGOL
Available for a mass audience and made it possible for general purpose usage.

Some of the most popular models of the 3rd generation of computers were the ICL 2903, ICL 1900, TDC-B16, IBM 360 and 370, Honeywell 6000, UNIVAC 1108, PDP-8, and PDP-11, which were ideal in their handling multiprocessing capabilities, reliability, and flexibility than previous generations.

4th Generation of Computer (1971-2010)

The microprocessor brought the fourth generation of computers, as thousands of integrated circuits equivalent to about millions of transistors were assembled and brought the whole central processing unit and other fundamental elements of the machine into a small chip called a microprocessor fitted on the CPU socket.

These computers used Very Large Scale Integrated circuits technology also called VLSI technology. After the invention, the microprocessor began to used in computing machines in the fourth and fifth generations of computers.

Within the framework of the considered generation in 1971, the first microprocessor appeared as an unexpected result of Intel’s work on calculator circuits and further development of minicomputers ( PDP-11 ).

The first personal computer and a microcomputer was “ ALTAIR ” developed by the company MITS in 1974. Also, the first microprocessor was the Intel 4004, manufactured in 1971, initially for an electronic calculator. Whereas the computers of the first generation filled an entire room, while now the 4th generation ‘microprocessors’ fit in the palm of the hand.

This generation of computers used an operating system based on the graphical user interface (GUI), which means these numbers were very easy to perform mathematical and logical tasks.

The computers started to utilize high-speed memory systems on integrated circuits with a capacity of several megabytes. Computer performance has increased significantly (hundreds of millions of operations per second).

The high-level language like C, C ++, Java, PHP, Python, Visual Basic, was utilized to compose programs in the computers of the fourth generation.

high-level languages in 4th generation of computers

The advent of the first personal computers in the mid-70s gave every common user the same computing resources that enormous computers had during the 60s. These computers were made more modest, faster, and less expensive can undoubtedly be put on a table or desk. Which marked the so-called era of personal computers .

Peripheral devices examples , such as mice, joysticks, handheld devices, etc., were developed during this 4th generation. Computers could be connected together in a network to share information with each other, this has played an important role in the birth and development of LAN, Ethernet, and the Internet .

The most popular companies in the world like Intel and AMD were rising. Then again, companies like Microsoft and Apple introduced their operating systems ‘Windows’ and ‘Macintosh’ in the generation of this computer. Because of which the act of multimedia started.

This is the era where personal computers were born, an idea that actually persists today. Also, these were the generation of DEC’s (Digital Equipment Corporation) minicomputers.

Characteristics of the 4th Generation of Computer:

Computers based on microprocessors and VLSI technology .
The computers of 4th gen were small in size, lightweight, and almost portable computers.
The integrating of multi cores in processors like Dual core , Octa core, etc has began.
The processing speed of this computer generation was much faster and reliable than the previous three generations.
The size and cost of power supply units has reduced.
Use of languages like C, C ++, .Net, Java, PHP, Python , Visual Basic.
Use of GUI Based OS with more memory capacity.
Accessible to the Internet .
Due to the low cost of these computers, they were available to every common man.

Desktops, Laptops, Workstations, Tablets, Chromebooks , and Smartphones, are examples of the fourth generation of computers.

Good to Know~ Alan Turing is the father of modern computers born in England in 1912.

5th Generation of Computer (2010-At Present)

Artificial intelligence is the name of the fifth as well as the latest generation of computers based on ULSI (Ultra Large Scale Integration) technology is the process of integrating or embedding millions of transistors on a single silicon microchip.

Computing in the 5th computer generation is versatile made portable, powerful, lightweight, innovative, comfortable with low electricity consumption . Because of the Internet’s advantages , it extended its limits of use to limits never before suspected.

The main objective of the latest fifth-generation computing and effort made by computer researchers is to make them smart by incorporating Artificial Intelligence so as to develop devices that respond to the input of natural language and are capable of learning and self-organizing even in 2022 it is under development.

This new information technology has greatly increased the size and working ability of the microprocessor, which has prompted the use of computers in the various fields of Entertainment, Accounting, Educational institutes , Film-making, Traffic-control, Business applications , and Hospitals, Engineering, Researches, Defense, etc.

That’s why a computer of the 5th generation is also known as the AI (Artificial Intelligence) generation of computers.

Introduction: A computer is an electronic device that manipulates information or data. It can store, retrieve, and process data. Nowadays, a computer can be used to type documents, send an email, play games, and browse the Web. It can also be used to edit or create spreadsheets, presentations, and even videos. But the evolution of this complex system started around 1940 with the First Generation of computers and evolving ever since.

Computers have evolved significantly over the years, and the history of computers is often divided into generations based on the technology used. Here are the five generations of computers:

First Generation (1940s-1950s): The first computers used vacuum tubes for processing and magnetic drums for storage. They were large, expensive, and unreliable.
Second Generation (1950s-1960s): The second generation of computers replaced vacuum tubes with transistors, making them smaller, faster, and more reliable. Magnetic core memory was also introduced, which was faster and more reliable than magnetic drums.
Third Generation (1960s-1970s): The third generation of computers used integrated circuits, which allowed for even smaller and faster computers. They also introduced magnetic disk storage and operating systems.
Fourth Generation (1970s-1980s): The fourth generation of computers saw the introduction of microprocessors, which made personal computers possible. They also introduced graphical user interfaces and networking.
Fifth Generation (1980s-Present): The fifth generation of computers is still ongoing, and is focused on artificial intelligence and parallel processing. This generation also saw the development of mobile computing and the internet.

Each generation of computers has built upon the advancements of the previous generation, leading to the computers we use today.

There are five generations of computers.

1946-1959 is the period of first generation computer.
J.P.Eckert and J.W.Mauchy invented the first successful electronic computer called ENIAC, ENIAC stands for “Electronic Numeric Integrated And Calculator”.
It made use of vacuum tubes which are the only electronic component available during those days.
These computers could calculate in milliseconds.
These were very big in size, weight was about 30 tones.

The microprocessor brought the fourth technology of computers, as 1000s of integrated brake lines we rebuilt onto just one silicon processor chip. A silicon chip which has a PROCESSOR. In the world of personal computers, the conditions microprocessor and CPU are being used interchangeably. In the middle of all personal computers and most work stations sits a microprocessor. Microprocessors also control the reasoning of almost almost all digital gadgets, from clock radios to fuel-injection systems for automobiles. Three fundamental characteristics distinguish microprocessors:

2. Instruction Established: The group of instructions that the microprocessor can easily execute.

* Bandwidth: The amount of bits highly processed in a single instruction.

* Time Speed: Given in megahertz (MHz), the clock rate determines just how many instructions per second the cpu can do. In the two cases, the higher the value, the more powerful the CPU. For instance , a 32-bit microprocessor that runs by 50MHz is more powerful than a 16-bitmicroprocessor that runs by 25MHz. The CPU is the brains of the computer. Sometimes referred to merely as the processor or perhaps central processor, the CENTRAL PROCESSING UNIT is in which most computations take place. With regards to computing electricity, the PROCESSOR is the most important component of a computer system. On significant machines, CPUs require a number of printed circuit boards. Upon personal computers and small workstations, the PROCESSOR is encased in a single nick called a microprocessor. Two standard components of a CPU happen to be:

* The arithmetic logic unit (ALU), which functions arithmetic and logical operations.

* The control device, which extracts instructions from memory and decodes and executes all of them, calling on the ALU when necessary. In 1981 IBM introduced its 1st computer for the home user, and 1984 Apple introduced the Macintosh. Microprocessors also transferred out of the realm of computer’s desktop computers and into various areas of life as more and more each day products started to use microprocessors. As these small computers became more powerful, they are often linked collectively to form systems, which at some point led to the introduction of the Internet. Fourth generation pcs also noticed the development of GUI’s, the mouse and handheld devices.

Fifth Generation ” Present and Beyond: Unnatural Intelligence Fifth generation computers, based on unnatural intelligence, remain in advancement, though there are some applications, including voice recognition, that are being used today. Artificial Intellect is the subset of computer science concerned with making computers act like human beings. The term was coined in 1956 simply by John McCarthy at the Massachusetts Institute of Technology. Unnatural intelligence involves: * Online games Playing: encoding computers to try out games just like chess and checkers

* Expert Devices: programming computers to make decisions in real-life situations (for example, some qualified systems help doctors diagnose diseases depending on symptoms)

5. Natural Vocabulary: programming pcs to understand organic human languages

* Neural Networks: Devices that replicate intelligence by attempting to reproduce the types of physical connections that occur in animal brains

* Robotics: coding computers to determine and hear and react to other sensory stimuli At the moment, no computers exhibit total artificial intellect (that is usually, are able to reproduce human behavior). The greatest developments have occurred in the field of games playing. The best computer chess courses are now competent of conquering humans. In May, 1997, a great IBM super-computer called Deep Blue conquered world chess champion Whilst gary Kasparov within a chess meet. In the area of robotics, computers are widely used in assembly plant life, but they are in a position only of very limited duties. Robots have got great problems identifying items based on presence or think, and they continue to move and handle things clumsily.

Natural-language processing offers the greatest potential rewards as it would allow visitors to interact with computers without needing any specialized know-how. You could simply walk up to a pc and talk to it. Regrettably, programming pcs to understand natural languages has proved to be more difficult than originally believed. Some basic translation systems that convert from one human being language to a different are existing, but they are not really nearly as nice as human interpraters.

There are also voice recognition systems that could convert used sounds in to written words and phrases, but they don’t realize what they are writing; they simply have dictation. Even these devices are quite limited ” you need to speak gradually and clearly. Today, the most popular area of unnatural intelligence is usually neural sites, which are showing successful in numerous disciplines such as voice recognition and artificial intelligence.

Generations of Computers

The section on computer awareness is a fairly new section of banking exams. So from this section, the topic on generations of computers is of prime importance. Here in this article, we will discuss the various generations of computers and the reasons that are important. Let us see!

First Generation Of Computers

Computers developed between 1946 – 1959, are the first generation of computers. They were large and limited to basic calculations. They consisted of large devices like the vacuum tubes. The input method of these computers was a machine language known as the 1GL or the first generation language. The physical methods of using punch cards, paper tape, and magnetic tape were used to enter data into these computers.

Be updated and don’t get stuck in an exam. Prepare your General Awareness topics here.

Examples of the first generation computers include ENIAC, EDVAC, UNIVAC, IBM-701, and IBM-650. These computers were large and very unreliable. They would heat up and frequently shut down and could only be used for very basic computations.

Second Generation Of Computers

Computers developed between 1959-1965 the second generation computers. These computers were more reliable and in place of vacuum tubes, used transistors. This made them far more compact than the first generation computers. The input for these computers were higher level languages like COBOL, FORTRAN etc. In these computers, primary memory was stored on the magnetic cores and magnetic tape and they used magnetic disks as secondary storage devices.

Examples of the second generation computers include IBM 1620, IBM 7094, CDC 1604, CDC 3600, UNIVAC 1108. As a result, they worked on AC and therefore were faster than their predecessors.

Third Generation Of Computers

Computers developed during the period of 1965 – 1971, the third generation of computers. These computers differed from the first and the second generations simply by the fact that a new circuit element like IC’s (Integrated Circuits) was used. An integrated circuit is a small device that can contain thousands and thousands of devices like transistors, resistances and other circuit elements that make up a computer. Jack Kilby is credited with the invention of the Integrated Circuit or the IC chips. With the invention of IC’s, it became possible to fit thousands of circuit elements into a small region and hence the size of the computers eventually became smaller and smaller.

Another salient feature of these computers was that they were much more reliable and consumed far less power. The input languages for such computers were COBOL, FORTRAN-II up to FORTRAN-IV, PASCAL, ALGOL-68, BASIC, etc. These languages were much better and could represent more information. Consequently more and more complex calculations are possible

Examples of the third generation computers include IBM-360 series, Honeywell-6000 series, PDP (Personal Data Processor), and IBM-370/168.

Fourth Generation Of Computers

Fourth Generation of computers was between 1971 – 1980. These computers used the VLSI technology or the Very Large Scale Integrated (VLSI) circuits technology. Therefore they were also known as the microprocessors. Intel was the first company to develop a microprocessor. The first “personal computer” or PC developed by IBM, belonged to this generation. VLSI circuits had almost about 5000 transistors on a very small chip and were capable of performing many high-level tasks and computations. These computers were thus very compact and thereby required a small amount of electricity to run.

Examples are STAR 1000, CRAY-X-MP(Super Computer), DEC 10, PDP 11, CRAY-1. This generation of computers had the first “supercomputers” that could perform many calculations accurately. They were also used in networking and also used higher and more complicated languages as their inputs. The computer languages like languages like C, C+, C++, DBASE etc. were the input for these computers.

Fifth Generation Of Computers

This is the present generation of computers and is the most advanced one. The generation began somewhere around 1981 and is the present generation of computers. The methods of input include the modern high-level languages like Python, R, C#, Java etc. These are extremely reliable and employ the ULSI or the Ultra Large Scale Integration technology. These computers are at the frontiers of the modern scientific calculations and are used to develop the Artificial Intelligence or AI components that will have the ability to think for themselves.

Examples include: Intel P 4, i 3 – i10, AMD Athlon, etc.

History of Computer: In 1822, Charles Babes first invented the Decentral and Analytical Encyclopedia, inspired by Pascalin, Digital Computer, in 1937, he envisioned an automated computer that had the ability to compute in accordance with artificial memory and program, but Herner Hollerith Also completed! The electronic tabulation machine was built to do all the work with the help of punchcard! This means that the first generation computer used a vacuum tube or vacuum valve.

Computer Inventors

In 1948 the transistor was replaced instead of the valve! With this, the heat generated in the vacuum tube could be detected by the heat! It was possible to create a computer that costs less and less space! In 1958, instead of the transistor, the integrated circuits on the silicon chip were used in the field of computer. It brought basic changes in the field of computer and a new revolution, which was said to be the third generation of computers! Because the size of the silicone chip-made computer is very small, they are called mini-computers.

Computer History by Year: The computer workshop and capabilities that developed through computer technology have resulted in the invention of computers for the generation of different generations and different types of the computer! This development of work capacity started called Computer Generation in 1964.

First Generation

Vacuum tubes (1940 – 1956): Vacuum tubes were used to control and transmit electronic signals, but a complete computer was created, but the computer’s hypothesis was first introduced by them. These used to create larger and more heat in the shape of tubes and they were likely to have broken-up and more malfunction, and the ability to calculate it was also very low and the first-generation computers used to occupy more space.

Second Generation

Transistor (1956 – 1963): Invented the transistor. During this time the transistors were used simultaneously in computers, which were more capable and cheap than valves. Those used to replace vacuum tubes for computer manufacturing. The size of the transistor is much smaller than vacuum tubes. By which the computer is small and its ability to calculate more and faster. Compared to the first generation, they were able to measure smaller and less heat and calculate more efficiency and faster speed.

Third Generation Computer

An integrated circuit (1964 – 1971): computers of this period could be used simultaneously. This became a significant basis for the third generation of synchronized chip development; technological efforts were made to further reduce the size of the computer, resulting in the creation of an integrated circuit on the silicon chip, which was used in computers. As a result, it was possible to produce the smallest size of the computer so far! Their speed was from microseconds to nanoseconds, which was possible by a small scale integrated circuit.

Fourth Generation Computer

The microprocessor (1971 – 1985): Microprocessor was used in the fourth generation computers! V.S.L.I. With the acquisition, thousands of transistors could be used for a single chip.

Fifth Generation Computer

Artificial Intelligence: In this fifth stage of development, artificial intelligence has been invested in computers! Such a computer has not been fully developed! We can see these types of computers in robots and various types of sound programs ! It will be more capable than humans.

In 1946, Eckart and Muchali’s Eniac (ENIAC-Electronic Numerical Integrator and Computer) was created by a computer. This generation of computers used a vacuum tube, invented in 1904 by John Ambrose Fleming.

2nd Generation

In 1956, the second generation of computers was started, these computers replaced the vacuum with a transistor instead of a vacuum tube. William Shockley was the inventor of the transistor.

3rd Generation

The third generation began in 1964. This generation used I.C. in computers. I.C. That is, the Integrated Circuit was invented by Jack Kilby, an engineer at the Texas Instrument Company.

4th Generation

Computers from 1971 to 1985 are classified as fourth-generation computers. The integrated circuit was further developed in this generation called Large Integrated Circuit.

5th Generation

Computers since 1985 are under the fifth generation. The 5th generation of computers includes powerful and supercomputers from the present to the future computers. Scientists today are trying to incorporate artificial intelligence into computers.

Now computers are so advanced that they are being used in every specific field, accounting, engineering, building, space and other types of research. Now it would not be wrong to say that without computers it has become impossible to work in these fields.

Efforts are being made to reduce the size of computers, as a result of which we can use computers in the shape of wristwatches. With the help of computers, we can exchange documents, information and money from anywhere around the world.

This article delves into the history of computer development, dividing it into different generations characterized by significant technological advancements that transformed how computers operate. It all began in 1940 when vacuum tube circuitry and magnetic drums were utilized for memory in the first-generation computers. These massive machines occupied entire rooms and incurred high costs while producing excessive heat that led to malfunctions. Their capabilities were limited to addressing one problem at a time, relying on punched cards and paper tape for input/output.

Among the pioneers of this generation were the UNIVAC and MANIAC, with UNIVAC becoming the first commercial computer deployed by a business client after being delivered to the U.S. Census Bureau in 1951. The second generation (1956-1963) witnessed a breakthrough with transistors replacing vacuum tubes. Transistors revolutionized computers due to their smaller size, faster speed, lower cost, improved energy efficienc

y, and enhanced reliability compared to their predecessors.

Although transistors still generated considerable heat posing potential harm to computers, they presented a significant upgrade from vacuum tubes. Punched cards remained prominent for input/output during this period as well as a shift from binary machine language towards symbolic or assembly languages.These new languages revolutionized programming by allowing programmers to use words instead of complex binary code. High-level programming languages like early versions of COBOL and FORTRAN were also developed during this time. In terms of memory storage, the computers in this generation utilized magnetic core technology rather than magnetic drum technology, making them ideal for use in the atomic energy industry.

The third generation of computers (1964-1971) brought about a significant advancement with the introduction of integrated circuits. This innovation greatly improved computer speed and efficiency. Additionally, users

now had keyboards and monitors to interact with their machines, thanks to an operating system that supported multiple simultaneous applications. A central program was implemented to monitor memory usage during this period.

As computer technology continued to advance, it became more accessible and affordable for a wider audience due to smaller sizes and lower costs. This progress marked the beginning of the fourth generation of computers (1971-Present). The integration of thousands of circuits onto a single silicon chip played a crucial role in reducing machine sizes from room-filling behemoths to pocket-sized devices.

In 1971, Intel introduced its groundbreaking 4004 chip which consolidated all computer components - including the central processing unit, memory, and input/output controls - into one chip. IBM followed suit by introducing its first home computer in 1981, while Apple's Macintosh made its debut in 1984. These developments further accelerated as microprocessors grew more powerful and started being incorporated into everyday products.The Internet was created by connecting small computers, which eventually led to the fourth generation of computing. This generation introduced innovative devices like mice and handheld gadgets. Currently, artificial intelligence development is being explored in fifth-generation computing. Some applications like voice recognition have already been implemented. Revolutionary advancements such as parallel processing, superconductors, quantum computation, molecular technology, and nanotechnology will further transform computers. The ultimate goal of fifth-generation computing is to enable devices with natural language understanding and self-learning abilities.
