  • block-structured — (language)   Any programming language in which sections of source code contained within pairs of matching delimiters such as "" and "" (e.g. in C) or "begin" and "end" (e.g. Algol) are executed as a single unit. A block of code may be the body of a subroutine or function, or it may be controlled by conditional execution (if statement) or repeated execution (while statement, for statement, etc.). In all but the most primitive block structured languages a variable's scope can be limited to the block in which it is declared. Block-structured languages support structured programming where each block can be written without detailed knowledge of the inner workings of other blocks, thus allowing a top-down design approach. See also abstract data type, module.

  • bootstrap loader — (operating system)   A short program loaded from non-volatile storage and used to bootstrap a computer. On early computers great efforts were expended on making the bootstrap loader short, in order to make it easy to toggle in via the front panel switches. It was just clever enough to read in a slightly more complex program (usually from punched cards or paper tape), to which it handed control. This program in turn read the application or operating system from a magnetic tape drive or disk drive. Thus, in successive steps, the computer "pulled itself up by its bootstraps" to a useful operating state. Nowadays the bootstrap loader is usually found in ROM or EPROM, and reads the first stage in from a fixed location on the disk, called the "boot block". When this program gains control, it is powerful enough to load the actual OS and hand control over to it. A diskless workstation can use bootp to load its OS from the network.
