Solutions

S1.Ans. (c)
Sol. A network is interconnection of two or more computers.

S2.Ans.(a)
Sol. A network interface card (NIC) is a circuit board or card that is installed in a computer so that it can be connected to a network. A network interface card provides the computer with a dedicated, full-time connection to a network.

S3.Ans.(b)
Sol. In the case of walkie-talkie, the person at one end sends signals, while the other on the receiving end receives these signals. The person at the receiving end cannot communicate until the person at the first end stops.

S4.Ans.(c)
Sol. A network server is a computer system, which is used as the central repository of data and various programs that are shared by users in a network.

S5.Ans.(d)
Sol. Printer is a shared common resource in a computer network.

S6.Ans.(c)
Sol. Each computer connected to the internet must have a unique IP address.

S7.Ans.(b)
Sol. Television is an example of simplex communication.

S8.Ans.(d)
Sol. Simplex is unidirectional while half duplex and full duplex communication modes are bidirectional. Difference between half duplex and full duplex is that the transmission of data is done one at a time in half duplex while simultaneous data transmission takes place in full duplex communication.

S9.Ans.(d)
Sol. An Internet service provider (ISP) is an organization that provides services accessing and using the Internet. Internet service providers may be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned.

S10.Ans. (c)
Sol. Through Telnet, an administrator or another user can establish a connection to someone else’s computer remotely. On the Web, HTTP and FTP protocols allow you to request specific files from remote computers, but not to actually be logged on as a user of that computer.

S11.Ans.(d)
Sol. optical fiber, co-axial cable and twisted pair wire are example of guided medium. Micro waves are unguided medium.

S12.Ans.(a)
Sol. Short for unshielded twisted pair, a popular type of cable that consists of two unshielded wires twisted around each other. Due to its low cost, UTP cabling is used extensively for local-area networks (LANs) and telephone connections.

S13.Ans.(a)
Sol. LAN is a privately owned network of an organisation. It is used to connect a computer with additional hardware, such as a printer, at home or in office. The range of LAN is restricted to a few kilometers only. It is more reliable and better speed for small area.

S14. Ans.(a)

S15. Ans.(b)
Sol. Bridges operate at the Data-Link Layer of the OSI Model. They can distinguish between local and remote data, so data traveling from one workstation to another in the same segment doesn’t have to cross the bridge. Bridges operate on MAC-Layer addresses.
