Computer Network

Pass information only to the selected destination or node. Higher transmission speed

Multiply network capacity by joining multiple networks. Filter and forward data signals to other nodes using same protocol. Build large network infrastructure

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.

A bridge is hardware networking device used to build communication among different computer network (LANs) that follows same protocols. Bridge helps in increasing network capacity by joining multiple networks. Bridge is more intelligent device as it knows which computer is part of which side and so allow those messages to get to the other side

A router is a hardware networking device that connects multiple physical networks that follows different protocols. A router is responsible for receiving, analyzing and moving incoming data packets to another network. A router ensures that packets are travelling the most efficient paths to their destinations based on data properties. A router is best suitable for

– A switch is a hardware networking device that connects multiple nodes, receives information from all nodes and sends it only to the selected node.– A switch has multiple ports to connect with multiple nodes.– A switch is called intelligent hub as it analyses and receives data and send it to intended node. A switch

– A hub is hardware networking device that connects multiple nodes in a network and send and receive data from all the connected nodes.– A hub contains multiple ports that are used to connect multiple nodes.– A hub is best suitable device for creating small home network (LAN). – A hub transmits data in half

A computer network is a system in which two or more autonomous computers are connected to each other. These computers can share information and other resources. A computer network may also include peripherals such as printers, scanners, webcams, speakers, headphones, microphones etc. you can use these devices to send and receive data and perform tasks,
