The computer is an amazing machine. Nowadays , we are living in the computer age and most of our day to day activities can not be accomplished without using computers. The computer has become an indispensable and multipurpose tool. We are breathing in the computer age and gradually the computer has become such a desire necessity of life. It is difficult to imagine life without computer. The computer is a latest breakthrough in science and technology because of the history of its development and the advantages of the computer as well as the prospect of it in the future.
The history of computer‘s development includes four generations. The first generation computers were invented in the 1940s and 1950s. ENIAC was the world first successful electronic computer. It was invented by two scientists namely J. P. Eckert and J. W. Mauchy. It was very huge and big. Its weight was 30 tones. It could store only limited or small amount of data. The second generation computers were invented from 1955 to 1960. The first transistor computer was created at the University of Manchester in 1953 and the most popular of transistor computers was IBM 1401.
Its transistors were used as the electronic component instead of vacuum tubes. The size of computer was decreased and it became much smaller than that of earlier computer. Next, the third generation computers were invented in the 1960s. They were invented in 1964. IC was used as the electronic component of computers. Those computers were developed by T. S. Kilby . They had huge storage capacity and higher calculating speed. Then, the fourth generation computers were invented from 1971 to now. This is the generation we are working today. Smaller computers have become available. The computer has many advantages .
The Essay on Computer Generations
The IC (Integrated Circuits) technology was used in third-generation computers. In a small IC chip (5 mm square size) a circuit is designed having large number of electronic components like transistors, capacitors, diodes, resistors etc. Initially, an IC contained only about ten to twenty components. Thus the IC technology was named as Small Scale Integration (SSI). The third-generation was based ...
It has become an important household item . It has become an indispensable device for us in the office , home or school . The computer helps people do many things quicker and faster than they did before. A very clear evidence is that documents can be composed without papers The computer allows the user to create documents , edit , print and store them so that they can be restricted later . Using the computer , one can remain connect to the world through the internet . The internet allows people from around the world to communicate with other people through chatting, email, etc.
People can also share knowledge, ideas and experiences in any field. Moreover , the computer is a wonderful device for people to entertain and relax such as listening to music , watching films , reading newspapers , playing games and so on . Nowadays , the computers are widely used for education and training purposes. In fact, the computers have become a learning tool for students . Nowadays, there are many universities that provide online degrees, which are advantages for those people staying in remote areas and for disabled.
One can take the benefit of such online degree programs staying at home without the need of relocation. The computers are also used for training purposes. Many companies use them to train their staff. The prospect of the computer is that the computer will be used to create more sophisticated computers. May be, everything would be a computer. The computers will be so complex. They will bring a lot of benefits. They will be able to fly planes and they will be able to coordinate the movements of several planes in the vicinity of an airport.
Furthermore, the computer not people could colonize the other planets and explore the galaxy. All in all, the computer is a wonderful device. Because of the history of its development, the advantages of the computer and the prospect of it, the computer has made a big breakthrough in science and technology. In fact, we live in a technological era, the computers have penetrated everywhere with all benefits they provide. We are satisfied with them and sometimes we even thank them because they help us in communicating, studying, doing business, entertaining and saving lives in critical situations.
The Essay on Computer Storage Devices
Computer Storage Devices Storage devices are used in order to store various items such as programs, data and instructions. Storage was used as early as 1804 by hole punching paper cards in order to control machinery. Without storage, the computer programs and files that exist now would not be possible. There are many different devices used for storage today such as hard drives, floppy drives and ...
