How to use the administration screen (continued) Glossary TCP/IP IP Address DHCP Subnet Mask Gateway WEP SSID Transmission Control Protocol/Internet Protocol (TCP/IP) is the standard protocol used for networking. Protocol is a set of technical rules for the transmission of information between computers. IP Address is the numbered address to identify a server for networking. Internet Protocol (IP) is the protocol to transmit data over the Internet, and the IP Address, which consists of exactly same numbers as the other address in one network, is not available. Dynamic Host Configuration Protocol (DHCP) is the protocol dynamically allocating IP addresses to computers on a local area network. The computer with DHCP server can assign IP address to each computer on a local area network automatically. Subnet is the separated part of network, and subnet mask is a number that defines a range of IP addresses that can be used in the network. Gateway is either hardware or software that acts as a bridge between two networks. Gateway is a system for transmitting data across networks that are incompatible and use different protocols. Wired Equivalent Privacy (WEP) is a security protocol that adds security by encrypting data. The encryption key enables only the authorized systems on the network to recognize the data. Service Set ID (SSID) is the identifier for wireless local area networks, which identifies the access points necessary for transmitting. Some wireless local area network card uses [ESSID (Extended Service Set Identifier)] or network name as SSID.
