    Appendix F Glossary The entries in this glossary are for your information. Not all of the concepts, technologies and protocols apply to the RaQ 4 server. 10/100 BaseTX An Ethernet connection over twisted-pair cables with a throughput of 10 Mb/s or 100 Mb/s.
  • Page 220 A protocol that requires carrier sense and in which a transmitting data station that detects another signal while transmitting stops sending, sends a jam signal and then waits for a variable period of time before sending again. Used in ethernet LAN technology. See Common gateway interface (CGI). Cobalt RaQ 4 User Manual...
  • Page 221 6.1 Mb/s. More typically, individual connections provide from 512 kb/s to 1.544 Mb/s downstream and about 128 kb/s upstream. A DSL line can carry both data and voice signals and the data part of the line is continuously connected. See Domain Name System (DNS). Cobalt RaQ 4 User Manual...
  • Page 222 See Extended Simple Mail Transfer Protocol (ESMTP). Ethernet The most widely used technology for local area networks (LANs). Standard ethernet runs at 10 Mb/s, 100 Mb/s or 1000 Mb/s. It balances speed, price, ease of installation and availability. Cobalt RaQ 4 User Manual...
