A laser pointer is a small pen-like handheld device that uses a power source (usually batteries) and diode laser to produce a coherent beam of monochromatic light. Laser pointers are used mainly for highlighting a point of interest by using a strongly colored beam of light. Typical low-end laser pointers that come with key chains are nothing more...
Bits per second (bps) is a measure used to show the average rate at which data is transferred between a computer and a data transmission system. The bit rate is generally measured in bits per second (bps) and sometimes bytes per second (Bps).
Bits per second is the standard measure of bit rate speed. However, millions of bits can be transferred in a second and measuring in single bit units can be cumbersome. To simplify data transfer rates, an International System of Units prefix is used. These include kilo, mega and giga.
