Bits per second of data transferred between two machines in a certain period of time (bps) to be measured in terms of band width It is called. As English bandwidth It is expressed as .
Bandwidth significantly affects the transfer capacity, quality and speed of an internet connection. The term bandwidth is used not only in the internet field but also in other technological fields. As an example, bandwidth can be thought of as water flowing through a pipe. So bandwidth, through a pipe (connection) flowing water (data) corresponds to the flow rate under various conditions.
In the early days of the Internet, bandwidth was first “bps” (bits per second) that is, measured as bit rate per second. However, today’s internet connections have much higher bandwidths. For these high bandwidths Mbps (megabits per second), Gbps (gigabits per second) And Tbps (terabits per second) is used.
- K = kilo = 1,000 bits
- M = mega = 1,000 kilos = 1,000,000 bits
- G = giga = 1,000 mega = 1,000,000,000 bits
- T = tera = 1,000 giga = 1,000,000,000,000 bits
After bandwidths expressed in terabits, corresponding to the power of 10, petabyte, exabyte, zettabyte yottabyte income. However, these bandwidth units are not yet widely used today. Home and workplace internet bandwidths are still around Mbps or Gbps.
Band width bits per second As can be expressed as, bytes per second (byte) aspect can also be expressed. The amount of bytes per second transferred is large “B” It is indicated by the letter. For example, a bandwidth of 5 megabytes per second is expressed as 5 MB/s or 5 MBps.
How is bandwidth measured?
Bandwidth measurement can be done with additional auxiliary software or the network card itself.
Programs used to measure bandwidth measure the efficiency of data transfer between two host computers. One of these two hosts is the sender and the other is the receiver. Measurement programs calculate the number of bytes transmitted between these two hosts and the transmission times of one-way packets.
More primitive methods can also be used to measure bandwidth. Transferring one or more files of known size and viewing how long the relevant transfer takes also gives an idea about bandwidth. The relevant result can be found by dividing the sent file size by the transfer time. Most speed test tools on the Internet use this method to calculate the bandwidth of that connection.
There is more than one way to define bandwidth.
- Theoretical maximum: It is the highest transfer rate achieved when ideal conditions are met. The theoretical maximum speed is a value obtained by testing a connection under the best possible conditions.
- Effective bandwidth: It is the most reliable bandwidth measurement for the bandwidth of a connection. Therefore, it is expected to be lower than the theoretical maximum bandwidth.
- Yield: It is the average successful data transfer rate of an internet connection. As mentioned above, it is determined by dividing the transferred data size by the transfer time. Bytes transferred per second (byte) It is measured in units and by comparing it with its theoretical maximum value, the performance of the connection can be revealed.
- Good input: It is calculated by the transfer time of the transferred file size, ignoring connection protocols.
- Total transfer: within a certain time period (e.g. 1 month) All traffic is monitored and the bandwidth used is calculated.
In today’s internet networks, bandwidth value changes from time to time, and a one-time bandwidth measurement is generally meaningless. The true bandwidth value of an internet connection requires a number of measurements.
Why is bandwidth measured?
There are multiple reasons to measure bandwidth. The first of these is that differences in the bandwidth between units connected to a network or in their output to the Internet tend to cause a network problem in the relevant system.
End users can use bandwidth measurement to find out whether they are getting the value they paid for and promised. Home users can get an idea about bandwidth value by performing internet speed tests.
How to increase bandwidth?
Bandwidths are available from relevant internet service providers. (ISP) can be purchased. In addition, modem, cabling and other software issues require control for connections that do not reach the bandwidth promised by the service provider.
It should be noted that the bandwidth of a wired internet connection is of higher quality and higher value than a wireless connection in most cases.
