Computer and Its Evolution - Essay Example

The history/evolution of computing predates silicon microchips and Cups by hundreds of years. The modern computers we are all familiar with can trace their roots back to simple computational machines that seem far removed from what we think of as a computer today. Simple Computers By definition, a computer is any device capable of performing mathematical equations or calculations. Therefore, many simple devices such as an abacus (which dates back to at least 300 BCC) or a slide rule (first made in England in the sass) are he forerunners of today’s modern computers.

The Calculating Clock The first machine that worked like a computer was a gear-powered German device dubbed the Calculating Clock. It was first created by Wilhelm Chaired in 1623, and it operated by pulling or pushing rods set inside a glass case. A similar device known as a Baseline became popular in the sass. These two devices were the forerunners of a steam-powered “difference engine” that was a pet project of Charles Babbage in he sass. Harvard Mark-I ; In 1944, the Harvard Mark-I computer Is completed.

This computer Is closer too modern computer, but is really Just a large calculator driven by a camshaft with no stored programs. This massive computer filled a large room and was a Joint effort between Harvard University and MUM. MENACE Another Important computer dating from the sass Is the MENACE, which was built between 1943 and 1945. ANEMIA (Electronic Numerical Integrator and Calculator) was a reject of the University of Pennsylvania, and spanned many rooms and used nearly 20,000 vacuum tubes.

The Dawn of the Microprocessor A microprocessor Is a chip that basically contains an entire computer (or at least a sass’s era computer) using a Integrated circuit. The first microprocessor was made by Intel in 1971. With the advent of this technology, the home computer become a possibility. The First PC The first personal computer for home use was the Altair 8800, which contained an Intel 8080 microprocessor.

However, this computer had to be assembled by the person who bought It. Computer and Its Evolution By roommate ; In 1944, the Harvard Mark-I computer is completed.
