4 bits – (a.k.a. tetrad(e), nibble, quadbit, semioctet, or halfbyte) the size of a hexadecimal digit; decimal digits in binary-coded decimal form 5 bits – the size of code points in the Baudot code, used in telex communication (a.k.a. pentad) 6 bits – the size of code points in Univac Fieldata, in IBM "BCD" format, and in Braille. Enough ...
MB in this context means 1,000×1,024 bytes. Depending on compression methods and file format, a megabyte of data can roughly be: a 1 megapixel bitmap image (e.g. ~1152 × 864) with 256 colors (8 bits/pixel color depth) stored without any compression. 6 seconds of 44.1 kHz/16 bit uncompressed CD audio.
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.

In this era, bit groupings in the instruction stream were often referred to as syllables [a] or slab, before the term byte became common. The modern de facto standard of eight bits, as documented in ISO/IEC 2382-1:1993, is a convenient power of two permitting the binary-encoded values 0 through 255 for one byte, as 2 to the power of 8 is 256.

Computers usually manipulate bits in groups of a fixed size, conventionally called words. The number of bits in a word is usually defined by the size of the registers in the computer's CPU, or by the number of data bits that are fetched from its main memory in a single operation.
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 ...
A PCI-X bus with 66 MHz clock and 64 bits wide can transfer 66 000 000 64-bit words per second, or 4 224 000 000 bit/s = 528 000 000 B/s, which is usually quoted as 528 MB/s. A PC3200 memory on a double data rate bus, transferring 8 bytes per cycle with a clock speed of 200 MHz has a bandwidth of 200 000 000 × 8 × 2 = 3 200 000 000 B/s ...
