In this network, all the nodes including computers and servers are connected to a single cable termed as Bus. there is no need of Network Server to control other devices. This topology eliminates the connection of nodes with the central node i.e. The nodes with Token are allowed to transmit data. Each node communicates with the nodes on its either side with the help of Token (information passing). In this network, the nodes are interconnected to make a closed loop. The central node is responsible for transmitting the message to the required destination. It is the most widely used topology for LAN’s. The devices are not connected to each other and transmits the messages to the Central Node. In this network, all the nodes are connected to Central Node. Topology is defined as the pattern of interconnection between the nodes of the network. 4 – Wireless Local Area Network (WLAN) LAN (Local Area Network) Topology With the help of WLAN connection, many devices can be connected simultaneously, provided they all are within the range of the Router.įig. The users can access the internet without wired connection (wireless) if they are within the range of the Router. The advantage of WLAN over LAN is the increased security it offers. It does not require cables to connect the devices. WLAN uses Radio waves as the means of communication. 3 – Ethernet Local Area Network WLAN (Wireless Local Area Network) Standard Internet Protocol is set, that allows the internet to run on different devices within the network.įig. In this type of connection, the network installation is wired and the Switches and Routers are configured using the network settings. WLAN (Wireless) Ethernet LAN (Wired connection)Įthernet LAN uses Ethernet cables to connect the devices in a network.2 – Schematic Diagram of Ethernet Local Area Network Types of Local Area Network (LAN) 2 shows schematic diagram of Ethernet LAN.įig.

Software has Application Programs which includes protocols defined by IEEE Standard. Fig. Hardware consists of transmission medium and connecting devices like Transceivers, Bridges, Switches, Repeaters etc. Like any other Networks, LAN also requires Hardware and Software components. Latest LAN’s can provide data rate up to 10 Gbps. It provides high data rates extending from 10-100 Mbps and up. In LAN, data is divided and transmitted in the form of packets and regenerated back by the receiving computer. Local Area Network is usually a privately owned network. In this type of Network, several computers and their peripherals like disc storage devices, printers are connected to a single high speed data line within a limited area.
LAN is basically a Data Communication Network.
