What is Bandwidth?

Understanding the Bandwidth


Bandwidth – frequency range; a characteristic of a communication channel showing how much data can be transmitted through this channel per unit of time. For systems using analog signals, it is measured in Hz, for digital channels (for example, satellite or fiber optic) – in Bit / s. (In the case of computer displays, bandwidth is measured in MHz and represents the product of horizontal resolution, vertical resolution, and screen refresh rate: 800x600x60 = 28.8MHz.)

For example, the surround channel in “Dolby Surround” has a frequency range of 100 Hz – 7 kHz. This means that the channel only passes frequencies between 100 Hz (bass) and 7 kHz (lower treble). The human ear distinguishes sounds in the frequency range of 20 Hz – 20 kHz.

What is throughput?

Throughput is a term given to the number of packets that are processed in a given period of time.

What is Latency?

Latency is used to measure how fast these conversations take place. The greater the delay, the longer these conversations are held. The latency level determines the maximum throughput of a conversation.

What is speed?

The data that is transferred through a certain connection for a certain amount of time is the speed. Bit rate is another term for speed. The speed cannot be higher than the bandwidth of the connection. “Bits per second” or bps helps measure the speed of a connection. Bitrate and bit rate are some other terms related to speed.

What is Network bandwidth?

Network bandwidth indicates the maximum number of conversations a network can support. Conversations are the exchange of data from one point to another.

What is internet bandwidth?

The bandwidth of the Internet channel, or, more simply, the speed of the Internet, is the maximum amount of data received by a personal computer or transmitted to the Network in a certain unit of time.
