Late 1950s - Early 1960s: Second Generation Computers
An important change in the development of computers occurred in 1948 with the invention of the transistor. It replaced the large, unwieldy vacuum tube and as a result led to a shrinking in size of electronic machinery. The transistor was first applied to a computer in 1956. Combined with the advances in magnetic-core memory, the use of transistors resulted in computers that were smaller, faster, more reliable and more energy-efficient than their predecessors.
Stretch by IBM and LARC by Sperry-Rand (1959) were the first large-scale machines to take advantage of the transistor technology (and also used assembly language instead of the difficult machine language). Both developed for atomic energy laboratories could handle enormous amounts of data, but still were costly and too powerful for the business sector's needs. Therefore only two LARC's were ever installed.
Throughout the early 1960s there were a number of commercially successful computers (for example the IBM 1401) used in business, universities, and government and by 1965 most large firms routinely processed financial information by using computers. Decisive for the success of computers in business was the stored program concept and the development of sophisticated high-level programming languages like FORTRAN (Formular Translator), 1956, and COBOL (Common Business-Oriented Language), 1960, that gave them the flexibility to be cost effective and productive. The invention of second generation computers also marked the beginning of an entire branch, the software industry, and the birth of a wide range of new types of careers.

Total copyright industries
The total copyright industries encompass the "core copyright industries" and portions of many other industries that either create, distribute, or depend upon copyrighted works. Examples include retail trade (a portion of which is sales of video, audio, software, and books, for example), the doll and toy industry, and computer manufacturing.

Caching
Caching is a mechanism that attempts to decrease the time it takes to retrieve data by storing a copy at a closer location.
