Bandwidth computer definition free#

As you request water, the water company delivers it to you. There's a pipe that delivers water from your rented water tank to your home okyourccool. You = patron / visitor of your website which is hosted on aforementioned web-server.Quantity of water delivered = bandwidth consumption,.Water company = hosting company where your web-server resides,.Rented Water Tank = web-server that hosts your website,.The more accurate phrase used for this meaning of a maximum amount of data transfer each month or given period is monthly data transfer. In website hosting, the term 'bandwidth' is often incorrectly used to describe the amount of data transferred to or from the website or server within a prescribed period of time, for example bandwidth consumption accumulated over a month measured in Gigabyte per month. Some authors prefer less ambiguous terms such as gross bit rate, net bit rate, channel capacity and throughput, to avoid confusion between digital bandwidth in bits per second and analog bandwidth in hertz. An explanation to this usage is that digital bandwidth of a bit stream is proportional to the average consumed signal bandwidth in Hertz (the average spectral bandwidth of the analog signal representing the bit stream) during a studied time interval.ĭigital bandwidth may also refer to: average bitrate (ABR) after multimedia data compression (source coding), defined as the total amount of data divided by the playback time. This meaning is for example used in expressions such as bandwidth shaping, bandwidth management, bandwidth throttling, bandwidth cap, bandwidth allocation (for example bandwidth allocation protocol and dynamic bandwidth allocation), etc. average data rate of successful data transfer through a communication path. The reason for this usage is that according to Hartley's law, the maximum data rate of a physical communication link is proportional to its bandwidth in hertz, which is sometimes called frequency bandwidth, radio bandwidth or analog bandwidth, the last especially in computer networking literature.īandwidth may also refer to consumed bandwidth ( bandwidth consumption), corresponding to achieved throughput or goodput, i.e. For example, bandwidth test implies measuring the maximum throughput of a computer network. In computer networking and computer science, digital bandwidth, network bandwidth or just bandwidth is a measure of available or consumed data communication resources expressed in bit/s or multiples of it (kbit/s, Mbit/s etc).īandwidth may refer to bandwidth capacity or available bandwidth in bit/s, which typically means the net bit rate, channel capacity or the maximum throughput of a logical or physical communication path in a digital communication system.
