Blood leaks into tissues under the skin and causes the black-and-blue color. As bruises (contusions) heal, usually within 2 to 4 weeks, they often turn colors, including purplish black, reddish blue, or yellowish green. Sometimes the area of the bruise spreads down the body in the direction of gravity.
(KiloBits or KiloBytes per SECond) One thousand bits or bytes per second. Kbps is a measurement of peripheral data transfer or network transmission speed. The correct abbreviation is b for bits and B for bytes; however, b and B are often interchanged. See space/time, Mbps and Gbps. Lower Case b - Kbps, Kb/sec, Kb/s Kilobits per second is used to rate serial data transmission devices such as analog modems.
Although they share the same letters, the abbreviations Mbps and MBps have different meanings. MBps stands for megabytes per second, with the bytes suffix referring to a unit of measurement for file size. In contrast, Mbps represents the bit capacity of a network connection. A bit is not the same size as a byte, so Mbps and MBps are not interchangeable. Each byte contains eight bits.
