An error from which a program or an operating system is able to recover, as opposed to a hard error, which causes program or operating system failure, requiring the user to reboot the system.
A type of computer memory that stores information in solid-state devices. The random access memory (RAM) used in personal computers is solid-state memory.
Source Data Acquisition
The process of sensing (as with a bar-code reader of other scanning device) or receiving source data.
Acronym for Scalar Processor Architecture. A RISC(reduced instruction set computing) microprocessor from Sun Microsystems, a workstation vendor. Sun hopes to establish SPARC as a standard and has made the chip specifications available to third-party manufacturers to encourage board use.
A process of storing data constituting a document to be printed in memory or in a file until the printer is ready to process it.
A region of reserved memory in which programs store status data such as procedure and function call return addresses, passed parameters, and (sometimes) local variables. The microprocessor, the program, and the operating system can all maintain one or more separate stacks. A stack is usually a data structure organized as a LIFO (last in, first out) list so that the last data item added to the structure is the first item used.
A special-purpose batch file stored in the root directory of the startup disk in OS/2. STARTUP.CMD can contain commands for initializing (tailoring) the system to the user’s needs or requirements. It is the OS/2 equivalent of an MSDOS AUTOEXEC.BAT file.
Allocation of memory that occurs, usually when the program starts. This memory remains allocated during the program’s execution and is not deallocated until the program is finished.
Abbreviated SRAM (pronounced “essram”). A form of semiconductor memory (RAM). Static RAM storage is based on the logic circuit known as flip-flop, which retains the information stored in it as long as there is enough power to run the device. A static RAM chip can store only about one-fourth as much data as a dynamic RAM chip of the same complexity, but static RAM does not require refreshing and is usually much faster than dynamic RAM. It is also more expensive. Static RAMs are usually reserved for use in caches.
A disk that contains an operating system and is capable of being used to boot start) a computer. In contrast, a data disk contains only data.
