Bandwidth

Bandwidth

• Data in digital computer system is represented in the form of bit ( binary digit).
• The amount of data ( amount of bits) that can be transmitted through a communication channel) during specific period of time is Bandwidth.
• The bandwidth in digital system is measured using the units bps (bits per second).
• Similarly, larger units are: 

                    Kbps: kilobits per second

                    Mbps: Megabits per second

• The bandwidth in analog system are measured using the unit hertz.

                      KHz: Kilo Hertz

                      MHz: Mega Hertz

                      GHz: Giga Hertz

• Some notes: 

Cable internet service (750MHz to 1000 MHz or 1 GHz)

Similarly, DSL and Satellite have high bandwidth connection

Note: Mb/s stands for Megabits per second

Whereas mb/s stands for millions of bits per second
