A router is a device that forwards data packets between computer networks. Routers are necessary to connect LANs to WANs. A router is connected to two or more networks, commonly two LANs and a WAN. When data packets are sent to the router, the router examines the destination address in the packet and determines the best way to forward the packet. The router forwards the packet to the next network on its path to the destination network.

What is a router in computer?
A router is a computer networking device that forwards data packets between computer networks. Routers are located at network gateways, the border between networks, and are the first point of contact for packets entering a network.
A router is connected to at least two networks, commonly two LANs or WANs, or a LAN and its ISP. When data enters one of the router’s interfaces, the router examines the destination address of the packet and determines the best outgoing interface to use to forward the packet to the next network.
Routers use a variety of methods to determine the best outgoing interface, including the destination network’s logical address, the router’s own logical address, the source network’s logical address, and the source host’s physical address.
Most routers also support a variety of routing protocols that help the router determine the best path to the destination network.
Is router and WiFi same?
In general, a router is a device that forwards data packets between computer networks, and a WiFi router is a specific type of router that includes an access point to provide a wireless local area network.
The terms “router” and “WiFi router” are not interchangeable, as a WiFi router includes functionality that a regular router does not. A regular router simply forwards data packets between computer networks, while a WiFi router also includes an access point that allows devices to connect to the router’s wireless network.
Most routers include built-in WiFi, but there are also routers that do not include WiFi and must be paired with a separate WiFi adapter in order to provide wireless access.
What is a router with example?
A router is a networking device that forwards data packets between computer networks. Routers are located at the edge of both networks, and are the first point of contact for packets arriving from one network and destined for another.
Routers use a routing table to determine where to send packets, based on the network addresses of the packets’ source and destination nodes. By default, routers are configured to forward packets to all other nodes on the network.
In addition to forwarding packets, routers can also filter packets based on their network addresses. Routers can also be configured to perform Network Address Translation (NAT), which allows multiple devices on a private network to share a single public IP address.
Most routers include a built-in firewall to protect the local network from unauthorized access from the Internet.

What is the best definition of router?
A router is a device that forwards data packets between computer networks. Routers are connected to two or more networks, commonly two LANs or WANs, and use routing tables to determine the best way to forward packets.
Routers are commonly dedicated hardware devices, but software-based routers also exist. When used in the context of a computer network, the term router refers to a layer-3 device.
What are the 4 types of routers?
There are four types of routers:
1. Physical router- This is the actual hardware that is used to create the network. It is a piece of equipment that is installed in your home or office.
2. Virtual router- This is a software program that creates a virtual network using your computer’s resources.
3. Router simulator- This is a software program that allows you to simulate a network without having any physical hardware.
4. Router emulator- This is a software program that allows you to emulate a network on a physical piece of hardware.
What are 2 main functions of a router?
In computing, a router is a device that forwards data packets between computer networks. Routers perform the “traffic directing” functions on the Internet. Data packets are forwarded based on the routing information contained in the packet header. A router uses its routing table to determine where to forward packets.
The two main functions of a router are:
1. Forwarding data packets between computer networks
2. Routing data packets based on the routing information contained in the packet header
Why do I need a router?
A router is a device that forwards data packets between computer networks. Routers are necessary because different networks use different protocols to communicate. Routers use routing tables to determine the best path for forwarding packets.
