32 bits (4 bytes) – size of an integer capable of holding 4,294,967,296 different values – size of an IEEE 754 single-precision floating point number – size of addresses in IPv4, the current Internet Protocol – equivalent to 1 "word" on 32-bit processors, including those for the Apple Macintosh, Pentium-based PC, PlayStation, GameCube ...
This is called byte-addressable memory. Historically, many CPUs read data in some multiple of eight bits. [3] Because the byte size of eight bits is so common, but the definition is not standardized, the term octet is sometimes used to explicitly describe an eight bit sequence. A nibble (sometimes nybble), is a number composed of four bits. [4]
The byte, 8 bits, 2 nibbles, is possibly the most commonly known and used base unit to describe data size. The word is a size that varies by and has a special importance for a particular hardware context. On modern hardware, a word is typically 2, 4 or 8 bytes, but the size varies dramatically on older hardware.

[28] [29] These limits allow memory sizes of 256 TB (256 × 1024 4 bytes) and 4 PB (4 × 1024 5 bytes), respectively. A PC cannot currently contain 4 petabytes of memory (due to the physical size of the memory chips), but AMD envisioned large servers, shared memory clusters, and other uses of physical address space that might approach this in ...
Byte is unit, in which files or other data is measured on that specific computer - of course, you can simulate different data types anywhere, but on PC, most hardware data (except flags, which are still usually contained in 8^n bit tuples) is kept in memory area, which is n*8 bits, where n is integer. In cases when data is kept in smaller units ...
The byte is a unit of digital information that most commonly consists of eight bits.Historically, the byte was the number of bits used to encode a single character of text in a computer [1] [2] and for this reason it is the smallest addressable unit of memory in many computer architectures.
File size is a measure of how much data a computer file contains or how much storage space it is allocated. Typically, file size is expressed in units based on byte . A large value is often expressed with a metric prefix (as in megabyte and gigabyte ) or a binary prefix (as in mebibyte and gibibyte ).
