what is band width data transfer and its applications ?

[Cyberfan]

I want what's the difference between them ?

[thomson]

Bandwidth mentions the quantity of data goes through a set of connections. Data transfer refers to amount of traffic generated and transported from one location to another

[fiberpools]

Bandwidth is the amount of data that can be transferred at one time.
Data transfer is the actual amount of data transferred.

Think of it this way. If bandwidth were a tunnel, the bigger the tunnel the more cars can pass through it. Data transfer would then be the number of cars allowed to go through the tunnel in a given time period, say a month.

[Manov]

It is the quantity of data that goes through a set of connections.

[DanielChew]

Bandwidth refers to the capacity of a communications line or channel to transmit or receive information. Bandwidth in this context is measured in bits, bytes, kilobytes, megabytes and gigabytes.

Data transfer is the amount of data that is transferred between your site and your visitors browser.

[jamsen]

In computer networks, bandwidth is often used as a synonym for data transfer rate - the amount of data that can be carried from one point to another in a given time period.

In general, a link with a high bandwidth is one that may be able to carry enough information to sustain the succession of images in a video presentation.

band width data transfer is the amount of data transferred at one time without any disturbance

[bidaddy]

In computing, bandwidth is the bit-rate of available or consumed information capacity expressed typically in metric multiples of bits per second. Variously, bandwidth may be characterized as network bandwidth,[1] data bandwidth,[2] or digital bandwidth.[3][4]

This definition of bandwidth is in contrast to the field of signal processing, wireless communications, modem data transmission, digital communications, and electronics, in which bandwidth is used to refer to analog signal bandwidth measured in hertz, meaning the frequency range between lowest and highest attainable frequency while meeting a well-defined impairment level in signal power.

Bandwidth is also described as the carrying capacity of a channel or the data transfer speed of that channel. Bandwidth exists in physical or wireless communication networks.

[Mangat Singh]

Bandwidth helps to describe the amount of data tranfer in Hertz and its application is Signal processing

[Sean9568]

Data transfer refers to the total amount of bytes of data server transfers to a site in a given amount of time. Whereas bandwidth refers to the maximum amount of data that is transferable in a given period of time.

[arianagrand]

Bandwidth is the amount of data that can be transferred at one time where as Data transfer is the actual amount of data transferred.
