It would also include discussion of mechanical, analog and digital computing architectures. As late as the s, mechanical devices, such as the Marchant calculator, still found widespread application in science and engineering. During the early days of electronic computing devices, there was much discussion about the relative merits of analog vs. In fact, as late as the s, analog computers were routinely used to solve systems of finite difference equations arising in oil reservoir modeling. In the end, digital computing devices proved to have the power, economics and scalability necessary to deal with large scale computations. Digital computers now dominate the computing world in all areas ranging from the hand calculator to the supercomputer and are pervasive throughout society.

Computer generations are based on when major technological changes in computers occurred, like the use of vacuum tubes, transistors, and the microprocessor. As of , there are five generations of the computer. Review each of the generations below for more information and examples of computers and technology that fall into each generation. The first generation of computers used vacuum tubes as a major piece of technology. Vacuum tubes were widely used in computers from through

Computers in the form of personal desktop computers, laptops and tablets have become such an important part of everyday living that it can be difficult to remember a time when they did not exist. In reality, computers as they are known and used today are still relatively new. Although computers have technically been in use since the abacus approximately years ago, it is modern computers that have had the greatest and most profound effect on society. The first full-sized digital computer in history was developed in Called the Mark I, this computer was used only for calculations and weighed five tons. Despite its size and limited ability it was the first of many that would start off generations of computer development and growth.

Computers are devices that accomplish tasks or calculations in accordance to a set of directions, or programs. The first fully electronic computers, introduced in the s, were voluminous devices that required teams of people to handle. They are not only thousands of times more expeditious, but also they can fit on your desk, on your lap, or even in your pocket. Computers are such an integral part of our everyday life now most people take them for granted. Computers work through an interaction of hardware and software. The whole picture of the computer goes back to decades.

Learn about each of the five generations of computers and major technology developments that have led to the computing devices that we use today. The history of computer development is a computer science topic that is often used to reference the different generations of computing devices. Each one of the five generations of computers is characterized by a major technological development that fundamentally changed the way computers operate. Most major developments from the 's to present day have resulted in increasingly smaller, cheaper, more powerful and more efficient computing devices. In this Webopedia Study Guide, you'll learn about each of the five generations of computers and the advances in technology that have led to the development of the many computing devices that we use today.
