Answer 1

1. What is networking?

Ans: Networking is the process of building networks which are defined as a group of computer systems

2. What is the function of a router?

Ans: Routers implement layer 3 or network layer functions. Their main job is to forward packets based upon a routing table. When doing so, they also provide traffic segmentation, multiple broadcast domains, and define network layer addressing subnets and networks. Those networks are defined by router network adapters or ports to which IP addresses are assigned. Those IP addresses are typically the default gateway to PCs and servers or other networking devices.

3. What is routing?

Ans: It is the process of path selection along with the packet of data can be moved from source system to destination system.

4. What is the best path to your destination?

Ans: This concept comes in picture when there are multiple routes connection a source to destination. It is cruicial to choose the best path considering the route that takes least time for the packet to reach destination.

5. What is a switch?

Ans: It is a networking device which is used to connect together multiple devices, inclusing computer, printers, servers, etc.

6. What is WAN, PAN, CAN, MAN and LAN?

Ans:

• LAN: A local-area network (LAN) is a computer network that spans a relatively small area. Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. Local Area Networks cover a small physical area, like a home, office, or a small group of buildings, such as a school or airport.
• WAN: A computer network that spans a relatively large geographical area, generally having a radius of more than 1 km. . Typically, a WAN consists of two or more local-area networks (LANs). Computers connected to a wide-area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites.
• MAN: A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN).
• CAN: A Controller Area Network (CAN bus) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer.
• PAN: A personal area network (PAN) is a computer network used for data transmission amongst devices such as computers, telephones, tablets, personal digital assistants, fax machines and printers, that are located close to a single user.

7. What is the largest WAN?

Ans: The Internet, it spans the whole Earth.
