(1) In computer science, tight coupling (or tightly coupled) is a type of coupling that describes a system in which hardware and software are not only linked together, but are also dependant upon each other. In a tightly coupled system where multiple systems share a workload, the entire system usually would need to be powered down to fix a major hardware problem, not just the single system with the issue.
(2) In software the term tight coupling is used to define software that will work only in one part of a specific type of system and the software is dependant on other software. For example, an operating system would be considered tightly coupled as it depends on software drivers to correctly install and activate the system’s peripheral devices.
Also called heavy coupling.
- tiled windows
Windows window arranged so that they do not overlap each other. Overlapping windows are often called overlaid or cascading windows.
- time code
A digitally encoded signal that is recorded on videotape to identify each frame of video by hour, minute, second and frame number. There are two kinds of recorded signal: longitudinal time code (LTC) and vertical interval time code (VITC). [Adapted from Extreme Exposure]
- time lapse
In digital photography, it’s the name of the process used to capture a set of images at preset intervals of time.
An interrupt signal generated by a program or device that has waited a certain length of time for some input but has not received it. Many programs perform time-outs so that the program does not sit idle waiting for input that may never come. For example, automatic bank-teller machines perform a time-out if you do […]
- time sharing
Refers to the concurrent use of a computer by more than one user — users share the computer’s time. Time sharing is synonymous with multi-user. Almost all mainframes and minicomputers are time-sharing systems, but most personal computers and workstations are not.
