Computer generations refer to the different stages of development and technological advancement in the field of computing. These generations are characterized by major technological developments and innovations that have significantly impacted the way computers are used and have revolutionized the field of computing.

The first generation of computers, which lasted from the 1940s to the 1950s, was characterized by the use of vacuum tubes as the primary electronic component. These computers were large, expensive, and consumed a lot of energy. They were also prone to errors and breakdowns due to the use of vacuum tubes, which had a tendency to burn out.

The second generation of computers, which lasted from the 1950s to the 1960s, marked the beginning of the use of transistors as the primary electronic component. Transistors were a significant improvement over vacuum tubes as they were smaller, more reliable, and consumed less energy. The second generation of computers also saw the development of programming languages such as COBOL and FORTRAN, which made it easier to write and execute programs on computers.

The third generation of computers, which lasted from the 1960s to the 1970s, was characterized by the development of integrated circuits. These circuits, also known as microchips, allowed for the creation of smaller and more powerful computers. The third generation of computers also saw the development of operating systems, which made it easier to use computers and allowed for the development of more sophisticated software programs.

The fourth generation of computers, which lasted from the 1970s to the 1980s, was characterized by the development of microprocessors. Microprocessors are tiny chips that contain all the components of a computer, including the central processing unit (CPU), memory, and input/output devices. The fourth generation of computers also saw the development of personal computers, which made computers more accessible to the general public.

The fifth generation of computers, which is still ongoing, is characterized by the development of artificial intelligence (AI) and machine learning. These technologies have allowed computers to perform tasks that were previously thought to be the exclusive domain of humans, such as language translation, image and speech recognition, and decision-making. The fifth generation of computers has also seen the development of the internet, which has revolutionized the way we communicate, access information, and do business.

In conclusion, the different generations of computers have been marked by significant technological advancements and innovations that have significantly impacted the field of computing and the way we use computers in our daily lives. Each generation has brought with it new capabilities and possibilities, and it is likely that the future will bring even more exciting developments in the field of computing.

Digital computer

short notes on computer generation

Computers can get viruses or get hacked and if they do, it may be a threat to the personal information of an individual or a company or bank, and many other institutions. It had been invented by Konrad Zuse in 1934 and it was hugely used till the 1980s. Transistors were used instead of Vacuum Tube. Each generation has been discussed in detail along with their time period and characteristics. These were not very reliable and programming on them was a very tedious task as they used high level programming language and used no operating system. The modern computer took its shape with the advent of time. Computer Generations Let us now discuss the development in Computer Technology over the different generations.

Dinesh has written over 500+ blogs, 30+ eBooks, and 10000+ Posts for all types of clients. They have very large storage capacity. It was around 16th century when the evolution of computer started. See First Generation In the late 1940s and early 1950s EDSAC, UNIVAC I, etc. The best examples are IBM 1401. These generations of computers plan to give highest priority to make the computers easy to handle and natural to use.

EDSAC: It stands for Electronic Delay Storage Automatic Computer and was developed by M. Supercomputer These are extremely fast computers, which can execute hundreds of millions of instructions per second. It was named Electronic Numerical Integrator and Calculator ENIAC. Programming was now done in Higher level language such as BASIC Beginners All purpose Symbolic Instruction Code. These computers used vacuum tubes and were bulky. A transistor may be a device composed of semiconductor material that amplifies a sign or opens or closes a circuit. Microprocessors, along with ICs, it became possible for computers to fit easily on a desk and also led to the introduction of the laptop.

See Fifth Generation - The Future The 21st century ushered in the fifth generation, which increasingly delivers various forms of artificial intelligence AI. The UNIVAC was also the first computer to come equipped with a magnetic tape unit and was the first computer to use buffer memory. The development of computer systems is normally discussed as the development over different generations. When machines, mainly computer systems, simulate the human intelligence processes, the technology is called artificial intelligence or AI. Programming language was shifted from high level to assembly language and made programming comparatively an easy task for programmers. It continuously improved itself in terms of speed, accuracy, size, and cost to get the shape of the modern day computer. People can store a great number of files on the computer instead of carrying so many paper files.

The computers using microchips were called microcomputers. This installation in Frankfurt, Germany in 1956 shows half the CPU top left and below. Memory semiconductor memory such as RAM, ROM, etc. Although most processing was still batch oriented using punch cards and magnetic tapes, online systems were being developed. ADVERTISEMENTS: Third Generation Computers 1965-1970 — Integrated Circuit The arrival of the Integrated Circuit or 1C brought along with it, the improvement on the second generation computers. The modern computer took its shape with the arrival of your time. Example: IBM PC, Apple-Macintosh etc.

Fourth Generation Computers 1971-? ENIAC was the first general-purpose electronic computer ENIAC Electronic Numerical Integrator and Computer was the first general-purpose electronic computer and is considered to be one of the first programmable computers as well. The mini computers were introduced in this generation. From 1940 through 1956, Vacuum tubes were widely used in One of the great examples of a first-generation computer is ENIAC. Honey well 200, CDC 1604, etc. The succession of advances in computer equipment, principally in logic circuitry, is often divided into generations, with each generation In 1946 electronic numerical integrator and computer , a digital machine and the first general-purpose, electronic computer. Von Neumann introduced the concept of stored program by around the same time and the first digital computer using program, EDSAC Electronic Delay Storage Automatic Calculator , was announced in 1949. The concept of private computers and computer networks came into being within the fourth generation.

Has poor control over Hardware. » Limited programming capabilities. They have very high speed of processing; they are 100% accurate, reliable, diligent and versatile. Mark I is the First Generation Computer. Examples: PDP-8, IBM1400 series, IBM 1620, IBM 7090, CDC 3600. It utilized a Mercury delay line, magnetic tape, and typewriter output.

History of Computer

short notes on computer generation

Charles Babbage who is known as the father of computers saw a need to negate the human errors in computations and the requirement of an automated system that would help with those errors. Advantages of First Generatin of Computer: » These computers fast and could calculate data in millisecond. More sophisticated search and natural language recognition are features that users recognize, but software that improves its functionality by learning on its own will change just about everything in the tech world in the future. The day the microprocessors invaded into our lives, they put a major impact on our day-to-day life. Earlier, the term generation was used to differentiate between different hardware technologies. It is easier to understand if compared to machine language.
