Access time, the Glossary

Index Access time

Access time is the time delay or latency between a request to an electronic system, and the access being completed or the requested data returned In a computer and software systems, it is the time interval between the instant at which an instruction control unit initiates a call to retrieve data or a request to store data, and the instant at which delivery of the data is completed or the storage is started.[1]

Computer

A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation).

See Access time and Computer

Data

In common usage, data is a collection of discrete or continuous values that convey information, describing the quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted formally.

See Access time and Data

Distributed computing

Distributed computing is a field of computer science that studies distributed systems, defined as computer systems whose inter-communicating components are located on different networked computers.

See Access time and Distributed computing

Hard disk drive performance characteristics

Higher performance in hard disk drives comes from devices which have better performance characteristics.

See Access time and Hard disk drive performance characteristics

Instruction set architecture

In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers.

See Access time and Instruction set architecture

Latency (engineering)

Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed.

See Access time and Latency (engineering)

Memory latency

Memory latency is the time (the latency) between initiating a request for a byte or word in memory until it is retrieved by a processor.

See Access time and Memory latency

Software system

A software system is a system of intercommunicating components based on software forming part of a computer system (a combination of hardware and software).
