Definition of Bandwidth
The concept
of bandwidth became popular in the last decades after the mass use of
the Internet . In computing , bandwidth is the amount
of data that can be sent and received in the framework of a communication . Said
bandwidth is usually expressed in bits per secondor in multiples of this
unit.
In general,
bandwidth is understood as a range for transferring data . The
notion is usually used with reference to the rate of data transfer that
is achieved in a communicative way. In the same
way, we can not overlook that it is also called network bandwidth or digital
bandwidth.
The
bandwidth in an Internet connection can be linked to the speed of
it. Let's suppose that 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 100
Mbit transfer. As you can lower, the higher bandwidth, it will be possible
to transfer more data per second and, therefore, the connection will have
greater speed .
In addition
to everything indicated, we must take into account another important series of
data about what bandwidth is and what it means. Specifically, among them
the following stand out: - Sometimes, we come across the fact that it is determined that a program will
put "brake" on 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 said
program does not use the available width so that other programs are not
affected.
That is, so that there are no problems among existing ones and
that everyone can make use of megabits. -According to the type of connection that the bandwidth has, it will be greater
or lesser. In this case, it can be established, for example, that with a
modem by telephone it will be 56 kbits / second while with Ethernet it can
reach 10 Mbits / second. -When a bandwidth service is contracted, it may happen that it is determined
that one is going to be able 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 hired is to use
different specific websites that are responsible for measuring it. The idea of bandwidth
also appears in the hosting services or web hosting . Companies
usually allow a certain amount of data transferred to or from a website on a
monthly basis .
This measure is the bandwidth. If we focus
on analog signals (ie, not digital), bandwidth is called the length
that exists between the frequencies where the highest power of the
signal is concentrated.
