where Z and POS are locations previously set to contain 0 and a positive integer, respectively; Unconditional branching is assured only if Z initially contains 0 (or a value less than the integer stored in POS). A follow-up instruction is required to clear Z after the branching, assuming that the content of Z must be maintained as 0.
Minicomputers (colloquially, minis) are a class of multi-user computers that lie in the middle range of the computing spectrum, in between the smallest mainframe computers and the largest single-user systems (microcomputers or personal computers).
A complex instruction set computer (CISC / ˈ s ɪ s k /) is a computer architecture in which single instructions can execute several low-level operations (such as a load from memory, an arithmetic operation, and a memory store) or are capable of multi-step operations or addressing modes within single instructions.
A given instruction set can be implemented in a variety of ways. All ways of implementing a particular instruction set provide the same programming model, and all implementations of that instruction set are able to run the same executables. The various ways of implementing an instruction set give different tradeoffs between cost, performance ...
A human computer, with microscope and calculator, 1952. It was not until the mid-20th century that the word acquired its modern definition; according to the Oxford English Dictionary, the first known use of the word computer was in a different sense, in a 1613 book called The Yong Mans Gleanings by the English writer Richard Brathwait: "I haue [] read the truest computer of Times, and the best ...
The IBM System/360 (S/360) is a family of mainframe computer systems announced by IBM on April 7, 1964, [1] and delivered between 1965 and 1978. [2] System/360 was the first family of computers designed to cover both commercial and scientific applications and a complete range of applications from small to large.
A programming language is a set of keywords, symbols, identifiers, and rules by which programmers can communicate instructions to the computer. [41] They follow a set of rules called a syntax. [41] Keywords are reserved words to form declarations and statements. Symbols are characters to form operations, assignments, control flow, and delimiters.
In computer science, zero instruction set computer (ZISC) refers to a computer architecture based solely on pattern matching and absence of (micro-)instructions in the classical [clarification needed] sense. These chips are known for being thought of as comparable to the neural networks, being marketed for the number of "synapses" and "neurons ...
