PEEK gets the byte located at the specified memory address. [1] POKE sets the memory byte at the specified address. [ 2 ] These commands originated with machine code monitors such as the DECsystem-10 monitor; [ 3 ] these commands are particularly associated with the BASIC programming language, though some other languages such as Pascal and ...
In computing (specifically data transmission and data storage), a block, [1] sometimes called a physical record, is a sequence of bytes or bits, usually containing some whole number of records, having a maximum length; a block size. [2] Data thus structured are said to be blocked.
A bit array (also known as bitmask, [1] bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits.It can be used to implement a simple set data structure.
The type and length are fixed in size (typically 1–4 bytes), and the value field is of variable size. These fields are used as follows: Type A binary code, often simply alphanumeric, which indicates the kind of field that this part of the message represents; Length The size of the value field (typically in bytes); Value
This is done by appending a zero byte to the transformed data, thus forming a packet consisting of the COBS-encoded data (the payload) to unambiguously mark the end of the packet. (Any other byte value may be reserved as the packet delimiter, but using zero simplifies the description.) Consistent Overhead Byte Stuffing (COBS) encoding process
In figure C above, when an argument larger than 11 bytes is supplied on the command line foo() overwrites local stack data, the saved frame pointer, and most importantly, the return address. When foo() returns, it pops the return address off the stack and jumps to that address (i.e. starts executing instructions from that address).
In this context, a byte is the smallest unit of memory access, i.e. each memory address specifies a different byte. An n-byte aligned address would have a minimum of log 2 (n) least-significant zeros when expressed in binary. The alternate wording b-bit aligned designates a b/8 byte aligned address (ex. 64-bit aligned is 8 bytes aligned).
Bytecode (also called portable code or p-code) is a form of instruction set designed for efficient execution by a software interpreter.Unlike human-readable [1] source code, bytecodes are compact numeric codes, constants, and references (normally numeric addresses) that encode the result of compiler parsing and performing semantic analysis of things like type, scope, and nesting depths of ...
