Computers have revolutionized the way we work, the way we communicate, the way we get information and the way we live. Computers can perform more tasks and provide new avenues of exploration and adventure. Computers help place telephone calls, computers are in our vehicles, read electrocardiograms, even design medical drugs, manufacturing products, connecting you to the internet and building our homes. They are used for complex tasks that would take humans a lifetime to do, it can even take on tasks that would be impossible for anyone to do.

The computers are the inventions of the 20th century. In 1946, ENIAC (electronic numerical integrator and calculator) was considered the first modern computer, it was built at the University of Pennsylvania. This computer was 80 feet long, 8 feet high, and weighs about 30 tons. Its circuits contained about 18,000 vacuum tubes. The ENIAC could perform 5000 additions or 300 multiplications a second, which was a break through at the time.

In the mid-1990’s, computers were small enough to be carried by a single person and are much more powerful than the ENIAC. The circuits contained millions of microscopic transistors. To transfer from one program to another, the user had to push a button or two. Also, these smaller computers can now process millions of calculations per second. As well as other technological advances had increased the use of computer throughout our society, even automobiles and our kitchen fridge were computerized.

There are four main sections about computers; how computers help children study for school, how computer work, computer applications and computer glossary.

How computers help student study

This section focuses on the several ways that computers are being use by students to help them with schoolwork and school assignments. This section demonstrate and describe the typical homework assignments, and display methods of carrying out and enhancing different school assignments. Although computer technology enriched the lives of millions of people around the world, it also produced some legal and ethical problems; these will be discussed at the end of this section.

How computers work

The majority of modern computers are digital computers, which interpret all data into Os and 1s. Small or large computers operate on the same general principles. This section will cover the basic concepts of computer science, explaining the computing process and the functionalities of a mixture of components within a computer system.

Computer programming

Such as computer algorithms, developing flowcharts, selecting an appropriate computer language, and using commands to write an actual program. Lastly, the section explain some of the techniques and advances in artificial intelligence (AI), the area of computer science that tries to imitate human behavior.

Computer software

One or more of the five major types of computer applications, known as word processing, database management, electronic spreadsheets, graphics, and communications, affect almost every occupation. All these types of programs, applications, or software, have an effect on not only businesses but also consumers, students, volunteer organizations, government agencies, and many other groups of people. This section discusses the factors about the capabilities of these applications programs and explains how they are use to perform a range of complex or simple tasks.
