| A bit represents a single binary digit either '0' or '1'. The '0' or '1' generally represent yes/no, true/false, on/off, or up/down/ It does not necessarily equate a '0' with false and a '1' with true. When transmitted over a network, the data is sent as a stream of bits (not bytes). A byte is generally used to signify a unit of memory or storage (i.e., RAM or ROM) that usually is eights bits long (wide) and is the smallest number of bits used to represent a character in the original [[dido:public:ra:xapend:xapend.a_glossary:a:ascii|ASCII]] character set used by most most computers. | A bit represents a single binary digit either '0' or '1'.

| - | Bandwidth is measured as bits per second and is used as a denominator of bits (i.e., kilobits, megabits). When bandwidth is used to describe a network connection (i.e., switch, server or router), it is generally in megabits, however, when it is used to describe the data flowing into the connection then bandwidth referred to as traffic and could be measured in either megabits per second (Mb/s or Mbps) or megabytes per second (MB/s or MBps). Although the nomencalture is subtle, it is important to be aware of the difference. An inadvertent misunderstanding could result in a error of magnitude 8 (i.e., 1 byte = 8 bits). | + | Bandwidth is measured as bits per second and is used as a denominator of bits (i.e., kilobits, megabits).

| Since the megabytes figure will be larger than the megabits figure (equation to follow shortly) most industry service providers like to give a total transfer based on this figure – however most bandwidth providers use megabits. | Since the megabytes figure will be larger than the megabits figure (equation to follow shortly) most industry service providers like to give a total transfer based on this figure – however most bandwidth providers use megabits. | ||
