INTRODUCTION In today’s modern world computer networks are the basic source of information exchange for all types of businesses. Different technologies are used within the context of networking depending on the requirements of an organization. Ethernet is off course the best technology for the “local area network” (LAN)‚ but when the organization spread their business to much longer distances (cities) then WAN technologies need to be deployed to keep the business running. The selection of an appropriate

Security Security document: Session 8 Laura Abraham Telecommunications Networks: CIS 313-DL Security will be implemented throughout different areas of the network: The main security will be the Cisco firewall: The IOS firewall works at both the network and application layer. This means that not only are we protected against intrusion at the network layer‚ the firewall will also protect against any application resources that we implement. Different firewall policies can be configured for

that connects a group of computers (’nodes’ in network terminology) to a token ring local area network. Networking Devices ... Bridges - used to join two network segments together‚ it allows computers on either segment to access resources on the other - can also be used to divide large networks into smaller segments Networking Devices ... Routers - networking devices used to extend or segment networks by forwarding packets from one logical network to another - most often used in large internetworks

Network Topologies Network topologies are an important part of the network. Without the proper topology‚ the network may not meet the needs of the organization. The layout of a network is referred to as the topology. How nodes in a network are connected to each other and communicate is determined by the topology. There are three basic topologies with several typical variations‚ or combinations. A description of four topologies follows. Mesh Topology Mesh topology is the first topology discussed
