GLOSSARY 91 MAC Address Media Access Control Address. Also called the hardware or physical address. A layer 2 address associated with a particular network device. Most devices that connect to a LAN have a MAC address assigned to them as they are used to identify other devices in a network. MAC addresses are 6 bytes long. Network A Network is a collection of computers and other computer equipment that are connected for the purpose of exchanging information or sharing resources. Networks vary in size, some are within a single room, others span continents. Network Interface A circuit board installed into a piece of computing equipment, for Card (NIC) example, a computer, that enables you to connect it to the network. A NIC is also known as an adapter or adapter card. Protocol A set of rules for communication between devices on a network. The rules dictate format, timing, sequencing and error control. RJ-45 A standard connector used to connect Ethernet networks. The "RJ" stands for "registered jack". Server A computer in a network that is shared by multiple end stations. Servers provide end stations with access to shared network services such as computer files and printer queues. SSID Service Set Identifier. Some vendors of wireless products use SSID interchangeably with ESSID. Subnet Address An extension of the IP addressing scheme that allows a site to use a single IP network address for multiple physical networks. Subnet mask A subnet mask, which may be a part of the TCP/IP information provided by your ISP, is a set of four numbers configured like an IP address. It is used to create IP address numbers used only within a particular network (as opposed to valid IP address numbers recognized by the Internet, which must assigned by InterNIC). Subnets A network that is a component of a larger network.
