Colocation Glossary Index
For definitions associated with co-location and datacentres, please browse the glossary of terms below.
Fast Ethernet
A LAN used to connect devices within a single building or campus at speeds up to 100 Mbps. Within the OSI model, Fast Ethernet is defined at layer one (physical) and layer two (data link). Also referred to as 100Base-T.
Fibre Optic Cable
A transmission medium composed of glass or plastic fibres; pulses of light are emitted from a laser-type source. Fibre optic cabling is the present cabling of choice for all inter exchange networks, and increasingly for the local exchange loops as well; it is high security, high bandwidth, and takes of little conduit space. Considered the physical medium of all future land-based communications.
Firewall
A firewall is a security measure that consists of a separate computer that acts as a 'bouncer' between the Internet and an internal network. Its job is to sift through all incoming traffic and turn away any undesirables and also to implement security measures.
Fixed Wireless
Wireless devices or systems that are situated in fixed locations, such as an office or home, as opposed to devices that are mobile, such as cell phones and PDAs. Fixed wireless devices normally derive their electrical power from utility mains, as opposed to portable wireless devices that normally derive their power from batteries.
Frame Relay
A packet-switching protocol for connecting devices on a Wide Area Network (WAN).
