Networking Topologies and TCP/IP protocol Bus Topology It just doesn’t get much simpler than the physical bus topology when it comes to connecting nodes on a Local Area Network (LAN). The most common implementation of a linear bus topology is IEEE 802.3 Ethernet. All devices in a bus topology are connected to a single cable called the bus‚ backbone‚ or ether. The transmission medium has a physical beginning and an end. All connections must be terminated with a resistor to keep data transmissions

and contrast wired and wireless LANs. What unique concerns must be addressed by the designer of a wireless networks. Answer 1:- Introduction: LAN is a local Area Network and a computer network covering a small physical area‚ like a home‚ office‚ restaurant or small group of buildings‚ such as a school‚ a college or an airport. Although a LAN can be used as an isolated network to connect computers in an organization for the sole purpose of sharing resources‚ most LANs today are also linked to a wide

Types of WLAN Private/Home WLAN This is the most common area to see a wireless. Home WLANs are meant to be used for small areas‚ usually with up to a 200-foot radius‚ and as such are suitable for homes or small businesses. The private WLAN subscribes to the 802.11 technology standard for wireless networking‚ with the most common being the 802.11b standard‚ often referred to as Wi-Fi. Private WLANS will frequently be based around a single router/access point which will connect to the Internet

What Topology works best for the factory floor‚ given its need for constant reconfiguration? 6. What kind of connection must you use to link the Allegheny Street and Mongahela locations? Answer: The availability of wiring closets for the office workstations indicates that a physical star topology will work (and indeed‚ these topologies are the most commonly used in that kind of

NT 1310 NETWORK TOPOLOGY PAPER: KENDAL JEFFERSON Network topology refers to layout of a network and how different nodes in a network are connected to each other and how they communicate. Mesh Topology: in a mesh network‚ devices are connected with many redundant interconnections between network nodes‚ in a true mesh topology every node has a connection to every other node in the network. There are two types of mesh topologies: Full mesh occurs when every node has a circuit connection it to every

Mesh‚ Bus‚ Ring and Star topologies Mesh A mesh topology typically refers to a Wide Area Network where there are multiple paths connecting multiple sites. A router is used to search multiple paths and determine the best path for the data. Routes are determined by least cost‚ time of day and performance. A three or four site mesh network is relatively easy to create‚ whereas it is impractical to set up a mesh network of 100 sites or nodes. Mesh networks are used in Wide Area Networks (WANs) where
