What is a Network Topology? Network Topology is the schematic description of a network arrangement, connecting various nodes(sender and receiver) through lines of connection. Types of Network Topology Bus Topology Bus topology is a network type in which every computer and network device is connected to single cable. When it has exactly two endpoints, then it is called  Linear Bus topology . Features of Bus Topology It transmits data only in one direction and every device is connected to a single cable. Advantages of Bus Topology It is cost effective, the cable required is least compared to other network topology, it can be used in small networks, it is easy to understand and it is also easy to expand joining two cables together. Disadvantages of Bus Topology When cables fails then the whole network fails, If network traffic is heavy or nodes are more the performance of the network decreases, the cable has a limited length, and it is slower than the rin

What is a Computer Network? A  computer network  is a set of  computers   connected together for the purpose of sharing resources. The most common resource shared today is connection to the Internet. Other shared resources can include a printer or a file server. Common types of area networks are: 1. Personal Area Network (PAN) The smallest and most basic type of network, a PAN is made up of a wireless modem, a computer or two, phones, printers, tablets, etc., and revolves around one person in one building. These types of networks are typically found in small offices or residences, and are managed by one person or organization from a single device. 2. Local Area Network (LAN) We’re confident that you’ve heard of these types of networks before – LANs are the most frequently discussed networks, one of the most common, one of the most original and one of the simplest types of networks.  LANs  connect groups of computers and low-voltage devices together across shor
