The term " computer ", in use from the early 17th century (the first known written reference dates from 1613), [1] meant "one who computes": a person performing mathematical calculations, before electronic computers became commercially available. Alan Turing described the "human computer" as someone who is "supposed to be following fixed rules ...
In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. [1] In many cases, a thread is a component of a process. The multiple threads of a given process may be executed concurrently (via multithreading ...
A portion of the computer's hard drive is set aside for a paging file or a scratch partition, and the combination of physical RAM and the paging file form the system's total memory. (For example, if a computer has 2 GB (1024 3 B) of RAM and a 1 GB page file, the operating system has 3 GB total memory available to it.)

Decimal, via standard IBM 80-column punched cards. Mass. 700 pounds (320 kg) The Atanasoff–Berry computer ( ABC) was the first automatic electronic digital computer. [1] Limited by the technology of the day, and execution, the device has remained somewhat obscure. The ABC's priority is debated among historians of computer technology, because ...
3D rendering of a Cray-1 with two figures as scale. The Cray-1 was a supercomputer designed, manufactured and marketed by Cray Research. Announced in 1975, the first Cray-1 system was installed at Los Alamos National Laboratory in 1976. Eventually, eighty Cray-1s were sold, making it one of the most successful supercomputers in history.
Theoretical computer science. Theoretical computer science ( TCS) is a subset of general computer science and mathematics that focuses on mathematical aspects of computer science such as the theory of computation (TOC), formal language theory, the lambda calculus and type theory . It is difficult to circumscribe the theoretical areas precisely.
Parsec (software) Parsec is a proprietary remote desktop application primarily used for playing games through video streaming. Using Parsec, a user can stream video game footage through an Internet connection, allowing one to run a game on one computer but play it remotely through another device. Although its main focus is gaming, Parsec can ...
