  2. Byte - Wikipedia

    en.wikipedia.org/wiki/Byte

    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.

    For example, 'kilobyte' often refers to 1024 bytes even though the standard meaning of kilo is 1000. Also, 'mega' normally means one million, but in computing is often used to mean 2 20 = 1 048 576. The table below illustrates the differences between normal metric sizes and the intended size – the binary size.

  4. Orders of magnitude (data) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(data)

    The order of magnitude of data may be specified in strictly standards-conformant units of information and multiples of the bit and byte with decimal scaling, or using historically common usages of a few multiplier prefixes in a binary interpretation which has been common in computing until new binary prefixes were defined in the 1990s..

  5. Orders of magnitude (bit rate) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(bit_rate)

    A group of 8 bits (8 bit) constitutes one byte (1 B). The byte is the most common unit of measurement of information (megabyte, mebibyte, gigabyte, gibibyte, etc.). The decimal SI prefixes kilo, mega etc., are powers of 10. The power of two equivalents are the binary prefixes kibi, mebi, etc. Accordingly: 1 kB = 1000 bytes = 8000 bits

  6. Data-rate units - Wikipedia

    en.wikipedia.org/wiki/Data-rate_units

    The ISQ symbols for the bit and byte are bit and B, respectively.In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet.The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per ...

  7. Comparison of Unicode encodings - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_Unicode...

    The tables below list the number of bytes per code point for different Unicode ranges. Any additional comments needed are included in the table. The figures assume that overheads at the start and end of the block of text are negligible. N.B. The tables below list numbers of bytes per code point, not per user visible "character" (or "grapheme ...

  8. Computer number format - Wikipedia

    en.wikipedia.org/wiki/Computer_number_format

    On most modern computers, this is an eight bit string. Because the definition of a byte is related to the number of bits composing a character, some older computers have used a different bit length for their byte. [2] In many computer architectures, the byte is the smallest addressable unit, the atom of addressability, say. For example, even ...

    They are used for low-level control functions. For instance, in Fibre Channel, K28.5 is used at the beginning of four-byte sequences (called "Ordered Sets") that perform functions such as Loop Arbitration, Fill Words, Link Resets, etc. Resulting from the 5b/6b and 3b/4b tables the following 12 control symbols are allowed to be sent:
