firewall
Software or hardware that protects the network applications and network-
ing stack of a computer workstation or server. IP Firewall services, which can be part
of computer operating systems software, scans incoming IP packets and rejects or
accepts these packets based on a set of filters you create.
FireWire

Code Modulation (PCM) of voice frequencies for a 3-KHz bandwidth at 48 kbps, 56
kbps and 64 kbps.
G.712
G.722
ITU (International Telecommunication Union) standard that specifies audio
for a 7-KHz bandwidth at 48 kbps, 56 kbps and 64 kbps using Adaptive Differential
Pulse Code Modulation (ADPCM) coding.
