FAQ: 15) Describe The Anatomy Of A Router. How Does A Router Differ From A Computer?

What is the structure of router?

is shown in figure 1, router architecture is composed of ports, buffers and combinational circuit (also called Routing Logic Block). Based on the routing scheme, combinational circuit connects the input port to the appropriate output port.

How do you describe a router?

A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets. A router is connected to two or more data lines from different IP networks.

What are the key differences between a switch and a router?

Router and Switch are both network connecting devices. Router works at network layer and is responsibe to find the shortest path for a packet whereas Switch connects various devices in a network. Router connects devices across multiple networks.

What is the difference between a router and a hub?

Hubs are classified as Layer 1 devices per the OSI model. To connect a network of personal computers together, they can be joined through a central hub. Directs data in a network. A router is a networking device that connects a local network to other local networks.

What is router and its types?

Wired and wireless routers Wired routers share data over cables and create wired local area networks (LANs), while wireless routers use antennas to share data and create wireless local area networks (WLANs).

What are the main components of a router?

A generic router has four components: input ports, output ports, a switching fabric, and a routing processor. An input port is the point of attachment for a physical link and is the point of entry for incoming packets. Ports are instantiated on line cards, which typically support 4, 8, or 16 ports.

What are 2 main functions of a router?

What are two functions of a router? (Choose two.)

  • It connects multiple IP networks.
  • It controls the flow of data via the use of Layer 2 addresses.
  • It determines the best path to send packets.
  • It manages the VLAN database.
  • It increases the size of the broadcast domain.

What is the purpose of a router?

What does a router do? Routers connect computers and other devices to the Internet. A router acts as a dispatcher, choosing the best route for your information to travel. It connects your business to the world, protects information from security threats, and can even decide which computers get priority over others.

What is the use of router?

A router receives and sends data on computer networks. Routers are sometimes confused with network hubs, modems, or network switches. However, routers can combine the functions of these components, and connect with these devices, to improve Internet access or help create business networks.

Which is better switch or router?

In various types of network environments (MAN/ WAN), the router works faster compares to Switch. In a LAN environment, a switch is faster than Router. Switches work with MAC addresses as it operates within the confines of a single network. Routers can work within both wired and wireless network situations.

Why use a switch over a router?

While a network switch can connect multiple devices and networks to expand the LAN, a router will allow you to share a single IP address among multiple network devices. In simpler terms, the Ethernet switch creates networks and the router allows for connections between networks.

Can you use a switch as a router?

A network switch can be used in place of a router but is not recommended. Internet Service Providers typically only provide one public IP address resulting in only one device being able to access the Internet when a switch is used instead of a router, as well as presenting major security concerns.

What is the purpose of a hub?

A hub is a physical layer networking device which is used to connect multiple devices in a network. They are generally used to connect computers in a LAN. A hub has many ports in it. A computer which intends to be connected to the network is plugged in to one of these ports.

Do you need a hub and a router?

Routers are needed to power the internet – there are no switches involved in getting data across the internet. While hubs don’t really pay any attention to addresses and switches work with MAC addresses, routers operate with IP addresses.

Can a router be used as a hub?

Turn Your Old Router into a Range-Boosting Wi-Fi Repeater By simply running an Ethernet cable between your old router to your current one (run a wire from one of the available LAN ports on your active router to the WAN-in LAN ports on the old router ), you can repurpose it as a network hub /switch.
