Sequential Access: A method of storing and accessing data in a row, or one after another. To access a record, all preceding records must be read first.
Set-up script: A text file that contains predefined settings for all the options specified during setup.
Soft Copy: A form of volatile output, usually a screen display.
Sort: To arrange data into a predetermined sequence.
SRAM (Static Random Access Memory): RAM which typically consists of one flip-flop per bit of memory. Unlike DRAMs, static RAM retains its contents as long as power is applied. Because there is no need to refresh the contents of memory addresses which are read, SRAM is faster than DRAM, but it is more expensive and typically is available in much smaller sizes than DRAM because each bit occupies more space on the chip.
State Memory: Data internal to a module that survives unchanged from invocation o invocation of that module.
Storage: Pertaining to a device into which data can be entered, in which it can be held, and from which it can be retrieved at a later time.
System File Table: System File Table is a DOS-internal data structure used to maintain the state of an open file for the DOS 2+ handle functions, just as an FCB maintains the state for DOS 1.x functions.
System Maintenance: The ongoing process of monitoring and evaluating a system.
Swap file: A hidden file on the hard drive that Windows uses to hold parts of programs and data files that do not fit in memory.
Testing: The fiendish and relentless process of executing all or part of a system with the intent of causing it to exhibit a defect.
Time bomb: A method of sabotaging a computer programs so that it will destroy itself after a predetermined time or action occurs.
Track: One of multiple concentric circular rings of data on a single data-bearing surface of a disk. Tracks at the same location on different surfaces form a cylinder.
TSR (Terminate and Stay Resident): A program which remains in memory after terminating in order to provide services to other programs or the user. The name comes from the name of the DOS function call used to remain in memory after termination.
UDF: Universal Disk Format, A file system developed by the Optical Storage Technology Association for storage of data on optical media.
