Kbps is the abbreviated form of kilobits per second. It is a measurement which indicates how many seconds it takes to transfer 1000 bits of data through a data connection.
In Switzerland, Kbps was the standard measurement used to indicate the speed of broadband and mobile data services for many years. As the speed of networks and connections improved, service providers began to list data transfer speeds in Mbps or Gbps.
Example: 1 byte is made up of 8 bits. If data is transferred at a constant rate of 1 Kbps, 125 bytes will be transferred in 1 second.
