OC-n[Optical Carrier] A basic unit defined in increments where n is a multiple of that unit. Uses optical fiber network.
STM-n[Synchronous Transfer Module] A basic unit defined in increments of 155.52 Mbps (OC-3/STM-1 seed)where n is a multiple of that unit.
STS-n[Synchronous Transfer Signal] Similar to OC-n but uses electrical network
SCSISmall Computer System Interface
*Note
The lowercase "k" is used to describe decimal kilobits and usually used in networking.
The uppercase "K" is used to describe binary kilobytes and usually used with memory
capacity.
