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 ...
1 MB = 1 024 000 bytes (= 1000×1024 B) is the definition used to describe the formatted capacity of the 1.44 MB 3.5-inch HD floppy disk, which actually has a capacity of 1 474 560 bytes. [5] Randomly addressable semiconductor memory doubles in size for each address lane added to an integrated circuit package, which favors counts that are ...
5.45 × 10 9 bits (650 mebibytes) – capacity of a regular compact disc (CD) 5.89 × 10 9 bits (702 mebibytes) – capacity of a large regular compact disc 6.4 × 10 9 bits – capacity of the human genome (assuming 2 bits for each base pair) 6,710,886,400 bits – average size of a movie in Divx format in 2002. [6] gigabyte (GB)
However, the capacity was also quoted "1.2 MB", [41] which was a hybrid decimal and binary notation, since the "M" meant 1000 × 1024. The precise value was 1.2288 MB (decimal) or 1.171 875 MiB (binary). The 5.25-inch Apple Disk II had 256 bytes per sector, 13 sectors per track, 35 tracks per side, or a total capacity of 116 480 bytes.
90 bytes: Enough to store a typical line of text from a book; 512 bytes = 0.5 KiB: The typical sector size of an old style hard disk drive (modern Advanced Format sectors are 4096 bytes). 1024 bytes = 1 KiB: A block size in some older UNIX filesystems; 2048 bytes = 2 KiB: A CD-ROM sector
The byte is a unit of digital information that most commonly consists of eight bits. 1 byte (B) = 8 bits (bit).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.

In telecommunications and computing, bit rate (bitrate or as a variable R) is the number of bits that are conveyed or processed per unit of time. [1]The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction with an SI prefix such as kilo (1 kbit/s = 1,000 bit/s), mega (1 Mbit/s = 1,000 kbit/s), giga (1 Gbit/s = 1,000 Mbit/s) or tera (1 Tbit/s = 1,000 Gbit/s).
