  2. Megabyte - Wikipedia

    en.wikipedia.org/wiki/Megabyte

    1.44 MB floppy disks can store 1,474,560 bytes of data. 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.

  5. Byte - Wikipedia

    en.wikipedia.org/wiki/Byte

    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. [8] The international standard IEC 80000-13 codified this common meaning. Many types of applications use information representable in eight ...

    Epic had been arguing for Microsoft to increase the memory for some time, and Tim Sweeney had sent Microsoft screenshots of what Gears would look like at 256 MB, and then at their proposed 512 MB. Shortly thereafter, Epic was the first studio told of the new 512 MB size specification and claimed it cost them a billion dollars but felt it was ...

  7. List of interface bit rates - Wikipedia

    en.wikipedia.org/wiki/List_of_interface_bit_rates

    While the gross data rate equals 33.3 million 4-bit-transfers per second (or 16.67 MB/s), the fastest transfer, firmware read, results in 15.63 MB/s. The next fastest bus cycle, 32-bit ISA-style DMA write, yields only 6.67 MB/s .

  8. 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 ...
