Advantages of Tree topology: It is most suitable for large networks. Failure of any node does not affect network communication. It is Flexible network because new node can be added easily without interrupting whole network. Large community for support. It provide highly secured network. Disadvantages of Tree topology: It depends upon central cable (backbone), which […]

Advantage of bus topology: It is very simple to design and install. less caballing is required as compared to other topologies. Best suited for small network (LAN). Very cost effective. easily expandable Disadvantages of bus topology: Not suitable for large network. If cable (backbone) is failed, entire network goes down. though its design is simple,

A gateway is a node considered as the entrance point to other networks, so that different networks can communicate with each other. It connects different network follows different protocols and different properties. Gateway can be any software, hardware or combination of both. Gateway can acts as a proxy server or firewall.

It is a networking device that forward data packets from source to destination machine over the network by using shortest path. It has advanced capabilities as it can analyze the data being carried over a network, decide or alter how it is packaged, and send it to another network of a different type.
