Kilobyte. The kilobyte is a multiple of the unit byte for digital information . The International System of Units (SI) defines the prefix kilo as a multiplication factor of 1000 (10 3 ); therefore, one kilobyte is 1000 bytes. [ 1] The internationally recommended unit symbol for the kilobyte is kB. [ 1]
1 MB = 1 048 576 bytes (= 1024 2 B = 2 20 B) is the definition used by Microsoft Windows in reference to computer memory, such as random-access memory (RAM). This definition is synonymous with the unambiguous binary unit mebibyte. In this convention, one thousand and twenty-four megabytes (1024 MB) is equal to one gigabyte (1 GB), where 1 GB is ...
When b is 2, the unit is the shannon, equal to the information content of one "bit" (a portmanteau of binary digit [2]). A system with 8 possible states, for example, can store up to log 2 8 = 3 bits of information. Other units that have been named include: Base b = 3 the unit is called "trit", and is equal to log 2 3 (≈ 1.585) bits. [3] Base ...
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. To disambiguate arbitrarily sized bytes from the ...
EMS supported 16 MB of space. Using a quirk in the 286 CPU architecture, the high memory area (HMA) was accessible, as the first 64 KB above the 1 MB limit of 20-bit addressing in the x86 architecture. Using the 24-bit memory addressing capabilities of the 286 CPU architecture, a total address space of 16 MB was accessible.
Memory address. In a computer using virtual memory, accessing the location corresponding to a memory address may involve many levels. In computing, a memory address is a reference to a specific memory location used at various levels by software and hardware. [ 1] Memory addresses are fixed-length sequences of digits conventionally displayed and ...
t. e. A binary prefix is a unit prefix that indicates a multiple of a unit of measurement by an integer power of two. The most commonly used binary prefixes are kibi (symbol Ki, meaning 210 = 1024 ), mebi (Mi, 2 20 = 1 048 576 ), and gibi (Gi, 2 30 = 1 073 741 824 ). They are most often used in information technology as multipliers of bit and ...
Conventional memory. In DOS memory management, conventional memory, also called base memory, is the first 640 kilobytes of the memory on IBM PC or compatible systems. It is the read-write memory directly addressable by the processor for use by the operating system and application programs. As memory prices rapidly declined, this design decision ...
