1) What are the components that are used in computer network.
Ans.: * Server
* Workstations
* Network Interface cards
* Cabling system
* Shared resources and peripherals.
2) What is the use of network interface cards.
Ans.: Network Interface Cards are used to control the flow of data between Personal computers and Workstations.
Network Interface Cards lie at Data Link Layer.
3) What is the standard supported by Wireless LANS?
Ans.: 802.11
4) Which is the backbone of networking.
Ans.:Routers (Also called as Gateways.)
5) What is a Brouter.
Ans.:It is a combination of Bridge and Router.
Shortcut: Brouter=Bridge+Router
6) Concurrency control is managed by
Ans.:Session Layer
7) . What is a Half Duplex.
Ans.:Data that can flow in both direction but in only one direction at a time.
8) What is Isosynchronous transmission.
Ans.:It is a cluster of Synchronous and Asynchronous transmission.
Tip: Isosynchronous =Synchronous+Asynchronous
9) Describe the use of ISDN.
Ans.:ISDN stands for Integrated Services Digital Network.
ISDN is used to integrate WAN with voice tile services.
10) What is congestion.
Ans.:Congestion is a situation that occurs when too many packets are to be sent over the network resulting in decrease in performance speed.
11) Who is a cracker.
Ans.:A cracker is one who breaks into a computer system without authorization aimed to destroy, steal secret,personal,confidential information.
12) What is spoofing.
Ans.:It is a technique of creating fake responses to keep a session active and prevent timeouts.
13) A standard e-mail supports
Ans.:RFC 822 Standard(Message Format).
14) Bandwidth of fibre optic cables
Ans.:1 Gbps
15) What is the Use of a concentrator.
Ans.:Used to connect more devices to a computer.
16) What are the types of transmission technology and transmission media?
Ans.: Transmission technolgies- Broadcast and Point to Point
Transmission media- Guided(Wired) and Unguided(Unwired) media.
17) What are the ways in which data can be exchanged?
Ans.: Simplex-Data can flow in one direction only.
Half-Duplex- Data can flow in both direction but in one direction at a time.
Full Duplex- Data can flow in both diretion at the same time.
18) What is the difference between baseband signal and broadband signal?
Ans.: Baseband signal-The entire bandwidth of the cable is consumed by a single signal.
Broadband signal-The bandwidth is utilised by multiple frequencies, allowing multiple signals to be sent at the simaltaeously.
19) Toplogies of network.
Ans.: Bus Topology: Each computer is directly connected to a network cable on a single line.
Star topology: All computers connected to a central hub.
Ring topology: All computers are connected in a loop.
20)What is mesh network
Ans.: A network in which there are multiple network links between computers to provide multiple ways for data to travel is called as a mesh network.
Ans.: * Server
* Workstations
* Network Interface cards
* Cabling system
* Shared resources and peripherals.
