1) WiFi and Bluetooth are technologies that are used for exchanging information between gadgets.
2) The term Modem is derived from the word MOdulator and DEModulator
3) RJ 45 connectors are attached to the end of the network cables using a tool called crimping tool .
4) Hub helps to send information from one computer to another.
5) Networking is the connection of computers with the help of cables or wires, with an intention of sharing information from one computer to another.
Q3) Write the abbreviation of the following terms :-
1) UTP cables : Unshielded Twisted Pair Cables
2) LAN : Local Area Network
3) WAN : Wide Area Network
4) RF : Radio Frequency
5) WiFi : Wireless Fidelity
6) TCP/IP : Transmission Control Protocol / Internet Protocol
7) Cat : Category
8) MAN : Metropolitan Area Network
9) DHCP : Dynamic Host Configuration Protocol
10) MODEM : MOdulator and DEModulator
Q4) State whether the following statements are True or False :-
1) Cables are required for interconnecting computers. True
2) UTP has 8 wires in it and arranged in 2 pairs. False
3) Hub sends the data only to the particular computer to which it should be send. False
4) Wireless Computers are the computers which are connected without cables. True
5) LiFi is a wireless network system that makes use of light. True
Q5) Write short notes on :-
1) Unshielded Twisted Pair Cables :- This cable is mainly used in connecting computers in a network. Inside the coated shield of the cable, there are 8 different coloured wires (Orange – White Orange , Blue – White Blue , Green – White Green and Brown – White Brown ) which are arranged in four pairs. This cable is also known as UTP cable.
2) Crimping Network Cables :- At end of the network cables, RJ 45 connectors are attached with the help of the tool called crimping tool. By using such tool connectors can be easily connected to cables. As soon as the wires in the cable are passed in the connector in a proper manner, then it is fixed using the tool.
3) Firewall :- A system that prevents other people from entering a computer through free medium like Internet without the permission of owner. This can be built using either a software or hardware.
4) Protocols :- As the computers are been interconnected to each other in a network, so it requires norms for computer address and methods for exchanging information between computers. The device which is connected in a network has to follow certain rules in regards to naming and exchanging information. Such rules are called as Protocols. TCP / IP , SSH , SMB , POP etc. are some examples of protocols.
5) Hubs and Switches :- These are used to control the exchange of information between computers within a network. But Hubs and Switches does not work same. Hub transfers the copies of information between the computers in a network. The network does not get congested whereas Switches sends the data only to the particular computer to which it should be send. As a result, the congestion in the network is reduced.
Q6) Answer the following questions :-
1) What is a Modem?
Ans :- Computers processes and saves the data in an electronic form. When such digital signal travels, through a telephone line, they become weak. Therefore information is send by converting these digital signals into analog. An equipment that convert digital signal into analog and analog signal into digital. The term MODEM is derived from the word Modulator and DEModulator. It helps to make available the Internet over a telephone line or other cable lines.
2) Explain the difference between Wired and Wireless Network
Ans :- Wired Network :- The computers are connected to each other with the help of wires, cables for sharing information or files within it. Wired Network is much more costier. Too much place is occupied. Its hard to detect an error in a Wired network.
Wireless Network :- The computers are connected to each other without the wires, cables. Radio Frequency waves are used instead of cables for sharing information or files within it. Wireless networks is cheaper. Less place is occupied. Easy to detect an error in a wireless networks.
3) Explain the term WiFi and Bluetooth
Ans :- This technologies are used for exchanging of information between the devices or gadgets. Radio waves of different wavelength are used for these purposes. Protocol standards, wavelengths, speed and range are different in these two technologies. The full form of WiFi is Wireless Fidelity. The Bluetooth uses only less power as if it is operated within a very limited range.
4) Explain in brief IP Address
Ans :- IP address is given to computer in a network based on the TCP/ IP protocol. IPv4 and IPv6 are the protocols are currently in use. An address of length 32 bits is given to the computer as per IPv4. IT has 4 parts of the size of 8 bits each separated by a dot (for ex. 192.168.1.120). But the address given as per IPv6 is of the size of 128 bits. When the system is connected to a network. It gets an IP address.The technology that gives an IP address automatically is known as DHCP (Dynamic Host Configuration Protocol). IP addresses under IPv4 have four parts. The first three parts are the same in all address. For ex: The IP address of a computer is 192.168.1.25. The common part (192.168.1) refers to a network and changing part (25) refers to computer.
