Bandwidth

Bandwidth is a term that has different meanings within different contexts. In terms of computing, bandwidth is defined as the bit-rate of available or consumed information and is typically expressed in units of bits per second (along with its metric multiples). Even within computing, bandwidth can be differentiated between network bandwidth, data bandwidth, and digital bandwidth. However, one of the most common ways in which the term bandwidth is used relates to the Internet, as "the volume of information per unit of time that a transmission medium [channel] can handle." Note that channel bandwidth, or the stated channel capacity, is not necessarily equal to the maximum amount of data that the channel can handle. Due to factors such as protocols and encryption, such as transmission control protocol (TCP), which is largely used in internet traffic, a channel stated to have a bandwidth of X bits per second may not actually transmit data at X rate.


In information technology, a bit is the smallest unit of information. It can hold only one of two values—0 or 1. A byte is a unit that consists of 8 bits. A byte can represent values from 0 to 255. The bit is the unit of data transfer, meaning that a communications device or system with a bandwidth of 8 MB has a transfer rate of 8 Megabits per second, which is equivalent to 1 Megabyte per second. In relation, the unit of information storage is the byte. In terms of memory or a hard disk, 8GB of capacity would mean that 8 Gigabytes of information could be stored, which is equivalent to 64 Gigabits.

The amount of bandwidth a person or company needs is entirely dependent on how they plan to use the Internet. Streaming or hosting large amounts of video, for example, requires far more bandwidth than simply browsing the Internet. The above calculators can be used to make estimations based on potential needs.
