Enterprise Network - connects many types of networks. Link - a ring or loop in a chain. Node - a point at which lines or pathways intersect or branch; a central or connecting point. Internet/the Internet - is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve several billion users

Wired and wireless LANs naturally use different topologies, the most commonly used topologies for wired LANs are bus, ring, star, tree and mesh. “A computer network topology is the physical communication scheme used by connected devices”. (Mitchell 2011).
Storage Area Network, SAN, is unique because it links storage media with application servers. Using a fiber channel protocol, iSCSI, you are able to link the devices you are using to the network. One common example is a copier/printer. You can link a couple

IS 589 Course Project Professor James Marion VoIP Implementation and Quality/Latency Issues Gaines Williams Introduction The term VoIP stands for voice over Internet Protocol. VoIP is related to the terms IP telephony and Internet telephony. At the most basic level, VoIP technologies enable analog telephone communications to be digitally transferred and routed over data networks—this can be done over a wide area network (WAN), a local area network (LAN) or the Internet. These two packets of communications, digitized voice and data, coexist and travel throughout a network. A third packet, video, has become an increasingly important network consideration for organizations because of its large bandwidth requirements.
