Router in Computer Network

Router of networking devices operating at network layer of OSI model. Routers are responsible for receiving analyzing and forwarding data packets among the connected computer network.

when a data pack arrives the router inspect the destination address consult it routing table to detect the optimal router, route and then transfer to the packet along the route.

Features of router:

Router os a network layer device.
Router connect different network together.
A router can be used in both Local area network (LAN), and Wide area network(WAN).
Transfer data in the form of IP packet in order to transmit data it uses IP address mention in the destination field of the IP packet.
Router has have a routing table, which change according to the change in the network.

why router:

A router is more capable as compared to other network devices such as hub, switch, etc.

As these devices are only able to execute the basic function of the network, but the router can analyze that traffic and work according to the network protocol.Router Also sharing a single network connected between multiple devices.

Types of Router:

Wireless Router:

Wireless router provide WiFi connection for WiFi devices like laptop, smart phone and other devices with Wi-Fi the range is up 150 feet while it has 300 feet for outdoor connections.

Brouter:

Brouter is a specific router that can provide the functionalities of both switch and bridge as well.

Core Router:

Core router can route data package within a given network but cannot route the packet between the network.

Edge Router (Access Router):

Edge Router is lower capacity divide that is played at the boundary of a network. They connect the internet network to connect with the external network.

Broadband Router:

Broadband Router are used to connect to the internet through telephone and to use voice over internet protocol (VOIP) Technology for providing high speed internet access.
