Units of Measurement
bit = smallest unit of digital information, i.e. ones & zeros
byte = a set of bits
bps = bits per second
Kbps = kilobits per second =1000 bits per second
Mbps = Million bits per second =1,000,000 bits per second
Gbps = Gigabits per second = 1,000,000,000 (one billion) bits per second
Tbps = Terabits per second = 1,000,000,000,000 (one trillion) bits per second
(Network speed is mesured in 1000 units, memory and storage space in 1024 units)
This is a list of different internet access connection speeds over a variety of different types of material. OC stands for Optical Carrier or in other words fiber connections. The method for communicating over fiber is called SONET (Synchronous optical networking). The connections listed above that do not start with OC are over traditional copper, twisted pair (Cat5) ethernet or coaxial cabeling.
