So the first byte held a map for blocks 0 to 7, the second byte held a map for blocks 8 to 15, and so on. Within a byte, the bitmap was ordered low-bit first. For example, the first byte would represent block 0 with the least significant bit and block 7 with the most significant bit.
The Khronos group uses blocks syntax to enqueue kernels from within kernels as of version 2.0 of OpenCL. [5] Like function definitions, blocks can take arguments, and declare their own variables internally. Unlike ordinary C function definitions, their value can capture state from their surrounding context.
In computer file systems, a block allocation map is a data structure used to track disk blocks that are considered "in use". Blocks may also be referred to as allocation units or clusters. [1] CP/M used a block allocation map in its directory. Each directory entry could list 8 or 16 blocks (depending on disk format) that were allocated to a file.
In computer programming, a block or code block or block of code is a lexical structure of source code which is grouped together. Blocks consist of one or more declarations and statements . A programming language that permits the creation of blocks, including blocks nested within other blocks, is called a block-structured programming language .
In a computer instruction set architecture (ISA), an execute instruction is a machine language instruction which treats data as a machine instruction and executes it.. It can be considered a fourth mode of instruction sequencing after ordinary sequential execution, branching, and interrupting. [1]

In computing, a process that is blocked is waiting for some event, such as a resource becoming available or the completion of an I/O operation. [1] Once the event occurs for which the process is waiting ("is blocked on"), the process is advanced from blocked state to an imminent one, such as runnable .
