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.

Though not hundred per cent artificial intelligence has been achieved till date but keeping in view the current developments, it can be said that this dream will also become a reality very soon. They used high level language for programming. Microprocessors, along with ICs, it became possible for computers to fit easily on a desk and also led to the introduction of the laptop. The initial computer faced many changes, obviously for the betterment. It is less prone to errors. The cost is also diminishing and reliability is of course increasing.

History of Computer

short notes on computer generation

The development of computer systems is normally discussed as the development over different generations. Although most processing was still batch oriented using punch cards and magnetic tapes, online systems were being developed. The fifth ones are on progress. They were large in size, slow in processing and had less storage capacity. Size was reduced and reliability was significantly improved. A single IC, has many transistors, registers and capacitors built on a single thin slice of silicon.

You might also be interested to know that the evolution of computers began sometime during the 1940s. Here a number of transistors were placed on silicon chips, called semiconductors. Easier than 3GL or 4GL to learn and use. It allows computers to behave like humans. Such evolution puts tremendous impact on our socio-economic life that brings a total revolution in itself. For example, ENIAC has used Vacuum tubes, relied on Machine Language and Boolean logic.

Dinesh authors the hugely popular Dinesh Thakur is a Freelance Writer who helps different clients from all over the globe. Some of the computers of this generation were: Mark I : The IBM Automatic Sequence Controlled Calculator ASCC , called the Mark I by Harvard University, was an electro-mechanical computer. They have very high speed of processing; they are 100% accurate, reliable, diligent and versatile. The size of computers was reduced with use of IC even more as compared to second-generation computers, and they became even more faster. IBM 1401: Its size was small to medium and used for business applications. First generation computers were used for calculation, storage and control purpose.

ENIAC was huge and used vacuum tubes to process its machine language programs. As of now, there are five generations of computers. Example: IBM 360, IBM 370 etc. Computers help to improve the performance of students as they help them to engage better with their school work. It weighed more than 30 short tons 27 t , was roughly 8 by 3 by 100 feet 2.

This was the era of mainframes and minicomputers, essentially large centralized computers and small departmental computers. See Fourth Generation The mid to late-1970s spawned the microprocessor and personal computer, introducing distributed processing and office automation. » They were not very reliable. IBM 1620: Its size was smaller as compared to First Generation computers and mostly used for scientific purpose.

Use of transistors made it possible to perform powerfully and with due speed. Earlier, the term generation was used to differentiate between different hardware technologies. Five generations of computers are there till 2020. One can also use these devices to create or edit presentations, spreadsheets and videos. Limitations of First Generation Computer Followings are the major drawbacks of First generation computers. The Difference Engine 1822 7. EDSAC, IBM 701, and Manchester Mark 1 are the other examples of first-generation computers.

Computers not only make the work easier for the students but also help with their education by enhancing their mathematical knowledge, problem-solving and critical thinking. They consumed lots of electricity and produced lots of heat. The concept of storing data and instructions inside the computer was introduced here. Computers of this generation were small in size, low cost, large memory and processing speed is very high. EDSAC: It stands for Electronic Delay Storage Automatic Computer and was developed by M.
