The switch will check the address of the destination computer and forward the message to the same computer. Provides privacy and security with the point-to-point links. 10q I didn't understand well before but now I'm Ok. Some advantages (merits) and disadvantages (demerits) of star network topology as follows: Advantages of star topology: Disadvantages of star topology: 2. Disadvantages of a Star Topology Requires more cable length than a linear topology. Here are additional advantages and disadvantages of bus topology to think about. Some advantages and disadvantages of ring network topology as follows: Advantages of ring topology: Disadvantages of ring topology: 3. Advantages of Star Topology. Now, it is the turn of the most important thing that helps you in deciding whether to go for it or not. A network topology is a pattern that devices are connected into local area network (LAN), in a short, which mostly uses some sort of cabling methodologies, such as copper wire and fiber-optic cable. While the isolation of devices happens to be its triumph card―with most of its advantages revolving around this particular aspect, its dependence on the central hub is definitely an issue of concern. 1. If there is a break in a cable or computer/node stops working, the entire network will not be affected. If anything, only the connection of a node will be broken if a component goes down. EDUCATION DEMYSTIFIED 188 views. List of the Advantages of Tree Topology . Easy to add or remove the computer in a network. Advantages and Disadvantages of Star Topology. The failure of a transmission line linking any host to the hub will result in the isolation of that host from all others, but the rest of the network will be unaffected. It’s relatively easy to troubleshoot, then other topology. The star topology possess numerous advantages hence it  is most widely used topology in today’s local-area networks (LANs). Due to its centralized nature, the topology offers simplicity of operation. So let us find out some points on advantages and disadvantages to know more about star topology. Du… Every node is connected to two nodes on each side. The network structure defines how they communicate. Star Topology Advantages and Disadvantages. • If the connecting network device (network switch) fails, nodes attached are disabled and cannot participate in computer network communication. … What Are the Advantages of Bus Topology? List of the Disadvantages of Star Topology. As against a star topology makes use of central hub or switch that broadcasts data to all the devices in the network. 3:12. The concept of star topology like a star with the central point is the center device and there are five computer devices that are the host that connect directly to the center point or the center device so as to produce the shape Like a star. Nodes are connected in a way that make a close loop, hence the name ring topology. All nodes (file server, workstations, and peripherals) are connected to the linear cable. Although the physical layout of this topology is not actually like a star. Complex process. EDUCATION DEMYSTIFIED 188 views. Adding or removing network nodes is easy, and can be done without affecting the entire network. Star-Bus Network Topology A Star-Bus topology is the combination of star network topology and bus network topology, in Star-Bus network a set of star topologies are interconnected by a central bus network. A network topology refers to the way in which nodes in a network are connected to one another. 3. 4. Disadvantages of the Star Topology.

This network can manage a high level of traffic. I am converting a cobbled together tree network into an expanded star, where each room or office is a star and the switch of each star connect to a master switch which connects to the internet through a server/gateway.
