Networks and computers play key roles in businesses today. Bandwidth is a term used in computer networking to quantify available or consumed data, and is expressed in bits, kbits, Mbits, etc. Also referred to as data transfer rate, bandwidth is the amount of data that is transferred from one point to another point in a given period of time. Bandwidth determines the speed of data transfer and the load it carries.
Businesses require high bandwidth in order to transmit voluminous data and run critical applications over the network. Oftentimes, multiple Wide Area Network (WAN) connections are used to provide increased bandwidth. Certain applications require high bandwidth, and an assessment of latency levels will help determine if bandwidth has to be increased. There is a sequence of links with individual bandwidth in a communications path. When one particular link is slow, it results in a bandwidth bottleneck. But there are technologies and solutions to overcome such impediments. Bandwidth is one of the two major factors that is critical for network performance, the other being latency. Improving network performance encompasses the analysis and usage level of bandwidth.
