A local area network (LAN) is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building using network media. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their usually higher data-transfer rates, smaller geographic area, and lack of a need for leased telecommunication lines.

The period 1953-1964 is generally taken to be the period of second generation computers. Sometimes, 1946-1958 is supposed to be the period of first generation computers. By 1948, the invention of the transistor greatly changed the computer's development. The transistor replaced the large, cumbersome vacuum tube in televisions, radios and computers. As a result, the size of electronic machinery has been shrinking ever since. From 1955 onwards transistors replaced vacuum tubes in computer designs, giving rise to the "second generation" of computers. A second generation computer, the IBM 1401, captured about one third of the world market. IBM installed more than ten thousand 1401s between 1960 and 1964.

Random-access memory (RAM) is a form of computer data storage. A random-access device allows stored data to be accessed in very nearly the same amount of time for any storage location, so data can be accessed quickly in any random order. In contrast, other data storage media read and write data only in a predetermined order.

Adam Osborne was an American entrepreneur who was best known for creating the first commercially available portable computer, the Osborne 1, released in April 1981. Ian Wilmut is best known as the leader of the research group that in 1996 first cloned a mammal from an adult somatic cell, a Finnish Dorset lamb named Dolly.
