In the 1940s, the US
and UK collaborated to develop radar technology to detect and fire at airplanes
to stop Germany from bombing London. There were also computing devices that
were used to decode enemy messages and perform scientific calculations.
The transistor was
invented by Bell Labs in 1947 and replaced vacuum tubes. The integrated circuit
was introduced by Texas Instruments in 1958. The Modem was introduced by Bell
Labs in 1962. It allowed mainframe computers to connect over phone lines.
Motorola introduced the first mobile phone in 1973. Ethernet was developed by
Xerox in 1974 to enhance computer connectivity.
Servers were
introduced by Cisco in 1984 to allow all computers to be connected. The
cordless phone was introduced in 1985 by AT&T. The internet was in
development from the 1950s to the 1980s when it was introduced for commercial
use and in 1995 the internet became available for all. Smartphones included
camera functions in 2002.
In the 1950s, the US
had a military radar using the technology developed in the 1940s. This radio
frequency device gave rise to other electronic devices. In 1960, the airlines
introduced its electronic reservation system.
IBM History Timeline. Founded on May 6, 1911, originally under the name of CTR (Computing Tabulating Recording
Company), IBMs first mainframe computer was introduced in 1952 operating using
vacuum tubes. Subsequent versions used transistors to replace the vacuum tubes.
The IBM 360 mainframe was introduced in 1964.
The IBM 370 mainframe was introduced in 1970.
The IBM 390 mainframe was introduced in 1990.
The IBM PC - 5150 Personal Computer was
introduced in 1981.
Nikola Tesla’s
work in the 1880s to 1920s with wireless radio waves contributed greatly to the
work done with radio frequency (RF) devices.
