IP BOLD - installation and operating instructions 71.2 Used terminology Ethernet is technology which is used to build up local networks (LAN) LAN - Local Area Network (local network) mark PC network which cover smallgeographical area (for example homes, office, etc…). 10Base-T As transmission medium use twisted twoline cable with rate10 Mbit/s. It used 2pairs of structured cabling from four. 100Base-TX Version with transmission rate 100 Mbit/s, which is named FastEthernet. It used 2 pairs UTP or STP cable category 5. Twisted 2line or also twisted pair is cable type which is used in PC networks.Twisted 2line is created by cables pair which are regularly twisted in the lengthand after pairs are twisted together. UTP, Unshielded Twisted Pair STP, Shielded Twisted Pair WEB - World Wide Web (WWW, shortly web), is mark for application of httpinternet protocol HTTP (Hypertext Transfer Protocol) is internet protocol design for exchange ofhypertex documents in format HTML USB (Universal Serial Bus) .
