Cards in this set: Term LAN (local area network) Definition A group of connected computers located in a single geographic area, usually a building or office, that share data and services. Term WAN (wide area network) Definition A data communications network that serves users across a broad geographic area. Term MAN (metropolitan area network) Definition A network that spans a defined geographic location, such as a city or suburb. Term PAN (personal area network) Definition A network layout whereby devices work together in close proximity to share information and services, commonly using technologies such as Bluetooth or infrared. Term peer-to-peer networking Definition A network environment where communication occurs between similarly capable network nodes that act as both clients and servers. Term client/server networking Definition A networking architecture in which front-end, or client, nodes request and process data stored by the back-end, or server, node. Term centralized computing model Definition A networking model where one system provides both the data storage and processing power for client systems. Term distributed network model Definition A networking model where the processing power distributed between the client systems and the server. Term VPN (virtual private network) Definition A network that uses a public network such as the Internet as a backbone to connect two or more private networks. Can also be used as a means of establishing secure remote connectivity between a remote system and another network. Term VPN client Definition The computer that intitates the connection to the VPN server. Term VPN server Definition A system that authenticates connections from VPN clients. Term VPN protocols Definition 1. Point-to-Point Tunneling Protocol (PPTP) 2. Layer 2 Tunneling Protocol (L2TP) Term VLAN (virtual local area network) Definition A group of connected computers that act as if they are on their own network segments, even thought they may not be. Term topology Definition A network's physical or logical layout. Term physical topology Definition The actual physical layout of the network. Term logical topology Definition The appearance of the network to the devices that use it, even if the physical layout is different. Term bus topology Definition A linear LAN architecture in which all devices are connected to a common cable, called a bus or backbone. Term ring topology Definition A logical network design in which data travels in a circular fashion from one computer to another on the network. Term star topology Definition A physical network design in which all nodes connect to a centralized device; in most cases a network switch. Term mesh topology Definition A network design in which each node is connected to every other node. This provides a high-level of redundancy as it provides alternate routes for data to travel should a single route become unavailable. Term infrastructure topology Definition A managed wireless topology that describes a wireless network composed of an access point connected to a wired LAN. Term ad hoc wireless topology Definition A wireless network layout where devices communicate directly between themselves without using an access point. Term access point Definition A transmitter and receiver device used to facilitate communication between a wireless client or WLAN and a wired network. Term point-to-point (PtP) Definition A wireless configuration where the communication link travels from one node directly to one other node. Term point-to-multipoint (PtMP) Definition A wireless configuration where signals travel from a central node, such as an access point. Term wireless mesh Definition A wireless configuration where each node is interconnected to other nodes on the network. Term hybrid topology Definition A combination of different network designs.
