What is the use of a channel?
The use of the channel is the standard measurement used in telecommunications fields and signal processing, measuring the speed and capacity of a specific information channel. Measurement of channel use allows good approximation of how the transfer source works effectively, except for the provision of adequate approximation, which will take, it will take to send information from point A to point B along a particular channel. In general, the higher the channel value, the faster the information travels to the virtual pipe.
The primary standard of measurement for the use of channel is in bit per second. This indicates the maximum number of bits that can go through a particular channel in any given second. Note that this is a necessarily changing character, because as with all transmission methods, natural signal speed fluctuate. This principle is obvious every time you download something from the Internet. Download speed is never just a static figure; This is slightly flowing depending on the circumstances of the operator concerning the connection.
As a result of this variability, the use of channel is best considered an average. Although the use of the channel is instant statistics, the more useful level of using the channel is not to consider what the specific data speed was at one particular time, but rather what the average data speed in a much longer sample time is. This provides more meaningful measurement of pipeline operation in the real world applications.
The picture - only measurement - the use of a channel at a certain time can reveal that the pipeline works at 500 bits per second. However, when receiving the average of use in the course of two weeks, it may seem that the average rate is not more than 250 bits per second, which is a significant difference. Therefore, the use of the channel is to use it as a diameter and use the medium rate of using the channel in a relatively long perio, providing the best rate of channel speed.
Also note that the use of the channel is measured as bits Inorwear enter the data pipe; No, because they leave. This means that the use of the channel is not a reliable measure of errors along the pipeline. In other words, the statistics of the channel use of the channel do not offer a way to determine how many of these bits "survived" their way. For this reason, remember that the use of channel is not a measure of reliability; It is the rate of raw speed itself.
