Question 1Differentiate between LAN, MAN, and WAN.

Accepted Answer

LANMANWANIt is used for a small networks like a room, office building or campus.MAN is much larger than a LAN setup and can spread across a city.WAN is used to link computers located at far away places (countries or continents).The maximum range of LAN can be 10 Kilometers.The maximum range of MAN can be 50 Km.The range of WAN is limitless as it uses telecommunication or satellite signals.The hardware as well as software resources are shared through LAN.The main purpose of a MAN is also to share hardware and software resources.The main purpose of WAN is to share data and information.LAN is usually used in schools, offices etc.WAN is commonly used in Cable Television Network.WAN is used as internet in houses, schools, banks and private and public sector.

Question 18

Question 2Describe the different types of networks.

Accepted Answer

There are four types of computer networks:LAN (Local Area Network) — LAN is used when two or more computers or peripheral devices are connected within a small area, like a room, office building, or a campus. The maximum range of LAN can be 10 Kilometers. The number of computers in a LAN varies from 2 to 1000. The hardware as well as software resources are shared through LAN.MAN (Metropolitan Area Network) — MAN is much larger than a LAN setup and is spread across a city. The most common example of a MAN type network is Cable Television Network. The main purpose of a MAN is to share hardware and software resources. The maximum range of MAN can be 50 Km.WAN (Wide Area Network) — WAN is used when we have two or more computers located at far away places, linked by communication facilities, like telecommunication or satellite signals. The most common example of a WAN network is the Internet which is generally used in houses, schools, banks and private and public sector. The main characteristic of a WAN is that it requires a public telecommunication media to transfer data.PAN (Personal Area Network) — PAN is mainly created for an individual person. It consists of a desktop/laptop computer, a mobile phone, and/or a handheld computing device, such as a PDA or a Smartphone. We can use these networks to transfer files including e-mail, calendar appointments, digital photos, and music. Personal area networks generally cover a range of less than 10 meters.

Question 19

Question 3Explain the types of modem.

Accepted Answer

Modems are available in two categories:Internal modem — These are attached to the internal slot of the motherboard. These are categorised as full duplex and half duplex which are used for fax and internet communications. They can also be used for data and voice communication.External modem — It is a small box connected to the communication port of the computer. It works similar to the internal modem. The only difference is that it is placed outside the CPU box.

Question 20

Question 4Explain any four advantages of networking.

Accepted Answer

The four advantages of networking are:Hardware Sharing — In a network, we can share almost every peripheral device, such as a printer, scanner, modem, CD writer, etc., among several computers. All these devices are attached to a remote server, which is shared among multiple computers. This reduces the cost of hardware.Software Sharing — Every application software can be installed on the main server rather than installing it on every computer individually. Computers in a network can use the required software from the server. This technique saves cost as well as time.Efficiency of Hardware and Software Resources — In a network, modifications in software or hardware are done at a single point. Since the resources are installed at a single point, all modifications are done at that point rather than in individual computers.Reduces Redundancy — Since people use the same data in a common workplace, they can share it over a network by saving and storing it centrally. This also reduces the redundancy of the same data.
