A computer is a general purpose device that can be programmed to carry out a finite set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem (source: Wikipedia).
A computer contains a processor and a tool for storing memory and hence retrieving stored data/information.
Computer process symbols as bytes of information and hence serve as a tool for conveying coded or digitized data.
The first computers were invented between 1940 and 1945 mostly as giant analog military devices. Since then, prominent high-tech computer companies such as Commodore, Tandy, Apple, IBM, Gateway, and Toshiba have successfully manufactured and effectively distributed satisfying home desktop personal computers and office-home laptops.
Special computer models of note include the Zuse Z3, the Commodore 64, the Apple IIe, and the Sony Vaio.
These special devices suggest that computer development has been coupled with digital marketability, augmenting the technological delight of special computer-themed Hollywood (USA) movies such as "Tron" (1982), "The Net" (1995), "Johnny Mnemonic" (1995), and "Virus" (1999).
Are they printing movie posters on hemp/recycled paper yet?
