Colocation Glossary Index
For definitions associated with co-location and datacentres, please browse the glossary of terms below.
Satellites
A communication satellite can be thought of as a big microwave repeater in the sky. A satellite dish is a broadband communication technology. It contains one or more transponders each of which listens to some portion of the spectrum, amplifies the incoming signal and then rebroadcasts at another frequency to avoid interference with the incoming signal.
The downward beam can be broad, covering large areas (e.g. direct broadcasting) or narrow, focusing on a small geographic area (e.g. pin pointing a ground station ).
Satellites can also be used for direct transmission between ground stations.
Server
A computer or device on a network that manages network resources. For example, a file server is a computer and storage device dedicated to storing files. Any user on the network can store files on the server. A print server is a computer that manages one or more printers, and a network server is a computer that manages network traffic. A database server is a computer system that processes database queries.
Set top Box
A transmission/reception device that acts as an interface typically to a television or other video output display device.
Signalling
The process of sending a transmission over a physical medium for purposes of communication.
Synchronous Transmission
Data transmission using synchronization bytes, instead of start/stop bits, to control the transmission.
