The concept of bandwidth it became popular in the last decades after the use of Internet . In the computing , is known as bandwidth at amount of data that can be sent and received within the framework of a communication . Said bandwidth is usually expressed in bits per second or in multiples of this unit.
Generally, bandwidth is understood as a range to transfer data . The notion is often used with reference to the data transfer rate which is achieved in a communicative way.
In the same way, we cannot ignore what is also called network bandwidth or digital bandwidth.
The bandwidth in an Internet connection can be linked to the speed of it. Suppose a company offers a bandwidth of 100 Mbit / s . This means that your network allows you to transfer (send / receive) up to 100 Mbit per second. In other words, in a second, it is possible to achieve the transfer of 100 Mbit. As it can be lower, at higher bandwidth, it will be possible to transfer more data per second and therefore the connection will have greater speed .
In addition to all of the above, another important series of data about what bandwidth is and means must be taken into account. Specifically, they include the following:
-On occasions, we run into the fact that it is determined that a program will “brake” the bandwidth it consumes. What this means is that it will limit the megabits per second that it will proceed to transmit. It will be carried out with the clear objective that this program does not use the available width so that other programs are not affected. That is, so that there are no problems among the existing ones and that everyone can make use of megabits.
-According to the type of connection that has the bandwidth will be greater or less. In this case, it can be established, for example, that with a modem by telephone it will be 56 kbits / second while with Ethernet you can reach 10 Mbits / second.
-When a bandwidth service is contracted, it may happen that it is determined that it will be possible to enjoy a specific one, but then, in reality, its “dimensions” are not the real ones. Therefore, a good alternative to check if that width is the one that has been contracted is to resort to different specific websites that are responsible for measuring it.
The idea of bandwidth also appears in the services of hosting or web hosting . Companies usually allow a certain amount of data transferred to or from a monthly basis. website . This measure is bandwidth.
If we focus on the analog signals (i.e. non-digital), the length of bandwidth between the frequencies where the highest signal strength is concentrated.
