The earliest type of machine used for computing was the abacus, dating back to possibly 3000 b.c. Still used in the 1990s, it was a simple system of beads that slid on wires. From this point, computer history was marked by "generations." The first generation of computers featured the use of vacuum tubes, which contributed to their characteristically huge size. This period lasted roughly from the late 1940s to the mid-1950s.

Computers have become a useful and necessary part of modern society.

They have been used in all types of businesses ranging from mail order and retail sales, to communications such as phone lines and internet access.

The number of Internet users grew vastly throughout the 1990s, and by 1998 about 5 million people were using the Web.

Trends in the computer industry in the late-1990s included rental or lease options on computer systems, numerous models of personal computers in the below $1,000 price range, portable laptop computers, and a change in popularity from the large mainframe business computers to a "client/server system" which used a set of smaller, faster, and cheaper computers.

The fourth generation of computers began in 1971 and continued into the late 1990s with the new development of large-scale integrated circuits.

This again reduced the size and price of computers.Other important computer businesses that began during the 1980s were Compaq Computers, Sun Microsystems, and Unisys Corporation.In the late 80s, Texas Instruments and Motorola marketed new microprocessors.Computers are prevalent in hospitals and supermarkets, universities and malls, restaurants and government agencies. Atanasoff and assistant Clifford Berry developed the first electronic computer circuits using Boolean algebra in 1940.By 1998, over 40% of all families in the United States had a personal computer. in 1896, which became International Business Machines (IBM) in 1924. In 1944, IBM finished the Mark I computer, which used electromagnetic signals.Microsoft's Windows, 1985, Windows 3.0, 1990, Windows NT, 1993, Windows 95, and Windows 98 became extremely popular operating systems due to the use of graphics which made them easy to use.
