Unformatted text preview: ITP 125 Lecture 4: Networking 101 Networks Topologies OSI TCP/IP NAT Overview 2 A series of interconnected systems and devices Can be many different sizes LANs, WANs, MANs, SANs Client-Server Peer to Peer Internet is one ginormous network Networks 3 Physical topology The way that the physical components of the network are arranged The way that humans see the network Logical topology The way that the networking topologies see the networking components Network Topologies 4 Topologies 5 Bus Topology Every component connected to a single line, with taps for each component Coaxial cable Physical: 10Base2, 10Base5 Advantages: Quick to deploy; cheapest Disadvantages: Lots of collision; unreliable; break in the line causes the network to fail; performance directly related to number of components Logical: Ethernet (most common logical topology) 6 Ring Topology Every component has 2 connections: left side and a right side Bus with a connection back around to the beginning Physical: 802.5 (again, coaxial cable) Logical: Token Ring Advantages: Performance not related to number of nodes Disadvantages: Performance generally sucks; not scalable; break in one connection causes complete network failure; token loss 7 Star Topology Each node connected to a central point Physical: 10BaseT/100/1000...
