COMPUTER NETWORKS NETWORK TELEPHONY –VOICE OVER INTERNET PROTOCOL(VoIP) VoIP is a set of technologies that enable voice calls to be carried over the internet (or other networks designed for data)‚ rather than the traditional telephone landline system-the Public Switched Telephone Networks(PSTN). VoIP uses IP protocols‚ originally designed for the internet‚ to break voice calls up into digital ‘packets’. In order for a call to take place the separate packets travel over an IP network and are reassembled

Bus Topology Bus networks (not to be confused with the system bus of a computer) use a common backbone to connect all devices. A single cable‚ the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see‚ but only the intended recipient actually accepts and processes the message. Ethernet bus topologies are

UMUC’s new building in Adelphi‚ MD will have to provide networking connectivity to students‚ professors‚ and staff. In order to begin the process of planning the new network‚ we will begin by planning the network IP addressing scheme. It is very important that the network IP addressing scheme be clearly defined in order for IT administrators to locate computers promptly. Also‚ in order to make it easier for the administrators‚ DHCP (Dynamic Host Configuration Protocol) will be used to assign

line 1. INTRODUCTION Wireless ad hoc networks have emerged to support applications‚ in which it is required/desired to have wireless variety of devices without relying on communications among a any infrastructure or central management. In ad hoc networks‚ wireless devices‚ simply called nodes‚ have limited transmission range. Therefore‚ each node can directly communicate with only those within its transmission range (i.e.‚ its neighbours) and requires other nodes to act as routers in

“Wireless Network” A wireless network is any type of computer network that uses wireless data connections for connecting network nodes. Wireless networking is a method by which homes‚ telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building‚ or as a connection between various equipment locations.[1] Wireless telecommunications networks are generally implemented and administered using radio communication.
