English Ethernet: A popular form of wired computer networking for Local Area Networks. Ethernet cable: There are two types of Ethernet cables. A straight-through cable is the most common and is used to connect devices on a network to a hub or router. A crossover cable is used to connect two devices that have Ethernet ports but that are not hubs or routers. Firewall: A combination of hardware and software tools that protect a network from unwanted entry. Gateway: A dedicated device (router or computer) that connects two different networks. For example, a computer on an Ethernet network may act as a gateway between the network and the Internet. Hub: A simple device that acts as the center of an Ethernet network. Other devices on the network are connected to the hub. IP address (Internet Protocol address): A unique number that identifies a device on a network. The IP address is often automatically assigned by DHCP or AutoIP. However, a device can be manually assigned a static IP address. Infrastructure network: A type of wireless network in which devices communicate with each other through a Wireless Access Point (WAP), such as a wireless network hub, router, or gateway. Network card: A network card enables a computer to communicate on a wired or wireless network. Network name: A network name is an alphanumeric, case-sensitive character string that provides basic access control to a wireless network. A network name is also known as a "Service Set Identifier (SSID)." Subnet: A small network that acts as part of a large network. It is recommended that the printer and the computers that use the printer all be on the same subnet. Subnet mask: A number that identifies the IP addresses that belong to a subnet. Switch: A network device that manages network traffic in order to minimize collisions and maximize speed. 59
