Bandwidth Definition

Bandwidth Definition Bandwidth describes the maximum data transfer rate of a network or Internet connection. It measures how much data can be sent over a specific connection in a given amount of time. For example, a gigabit Ethernet connection has a bandwidth of 1,000 Mbps, (125 megabytes per second). An Internet connection via cable modem may provide 25 Mbps of bandwidth. While bandwidth is used to […]

Megabyte Definition

Megabyte Definition A megabyte is 106 or 1,000,000 bytes. One megabyte (abbreviated “MB”) is equal to 1,000 kilobytes and precedes the gigabyte unit of measurement. While a megabyte is technically 1,000,000 bytes, megabytes are often used synonymously with mebibytes, which contain 1,048,576 bytes (220 or 1,024 x 1,024 bytes). Megabytes are often used to measure the size of large files. For example, a high […]

Terabyte Definition

Terabyte Definition A terabyte is 1012 or 1,000,000,000,000 bytes. One terabyte (abbreviated “TB”) is equal to 1,000 gigabytes and precedes the petabyte unit of measurement. While a terabyte is exactly 1 trillion bytes, in some cases terabytes and tebibytes are used synonymously, though a tebibyte actually contains 1,099,511,627,776 bytes (1,024 gibibytes). Terabytes are most often used to measure the storage capacity of large storage devices. While hard […]

Kilobit Definition

Kilobit Definition A kilobit is 103 or 1,000 bits. One kilobit (abbreviated “Kb”) contains one thousand bits and there are 1,000 kilobits in a megabit. Kilobits (Kb) are smaller than than kilobytes (KB), since there are 8 kilobits in a single kilobyte. Therefore, a kilobit is one-eighth the size of a kilobyte. Before broadband Internet was common, Internet connection speeds were often […]

Mbps Definition

Mbps Definition Stands for “Megabits Per Second.” One megabit is equal to one million bits or 1,000 kilobits. While “megabit” sounds similar to “megabyte,” a megabit is roughly one eighth the size of a megabyte (since there are eight bits in a byte). Mbps is used to measure data transfer speeds of high bandwidth connections, such as […]

Kbps Definition

Kbps Definition Stands for “Kilobits Per Second.” 1 Kbps is equal to 1,000 bits per second. That means a 300 Kbps connection can transfer 300,000 bits in one second. 1,000 Kbps is equal to 1 Mbps. Kbps is primarily used to measure data transfer rates. For example, dial-up modems were rated by their maximum download speeds, such as 14.4, 28.8, and 56 Kbps. […]

Byte Definition

Byte Definition A byte is a data measurement unit that contains eight bits, or a series of eight zeros and ones. A single byte can be used to represent 28 or 256 different values. The byte was originally created to store a single character, since 256 values is sufficient to represent all lowercase and uppercase letters, numbers, and […]

Bit Definition

Bit Definition A bit (short for “binary digit”) is the smallest unit of measurement used to quantify computer data. It contains a single binary value of 0 or 1. While a single bit can define a boolean value of True (1) or False (0), an individual bit has little other use. Therefore, in computer storage, bits are often grouped together […]
