​ KembaraXtra-Computer Terms – block:
In computing, a block generally refers to a group of related items that are handled together as a single unit. For example, it may represent a section of memory temporarily assigned to a program by the operating system or a group of instructions within a program that execute together when certain conditions are met.
Blocks also appear in many other contexts within computing. They may refer to units of data transferred between devices, groups of bytes read or written to storage devices, rectangular groups of pixels in graphics processing, or segments of text selected for editing. In programming languages such as Java, any code enclosed within matching braces forms a block.
