A. Tick (P) the correct alternative :
1. LAN stands for :
(a) Local Area Network
(b) Star Topology
(c) Wide Area Network
(d) Internet
2. In batch processing jobs are served on the basis of:
(a) FIFO
(b) LIFO
(c) Request
(d) None of these
B. Write T' for true and 'F' for false statement:
1. Network makes a system fast. - True
2. CPU allocates an equal amount of time to all the users in
time sharing system. - True
3. Multiprocessing can be done only on multiprocessor
system. - True
4. In Star Topology, the whole network collapses, if server
collapses. - True
5. A Real Time system does not response within the required
time. – False
C. Fill in the blanks :
1. A computer can be connected to others via cable or satellite.
2. Modem is used to convert digital signal into analog and vice versa.
3. Batch Mode is suitable only when processing of data is
required in batches.
4. CPU is the heart of computer.
5. Indian Railway Reservation System is the example of real time system.
D. Answer the following questions:
1. How does data travel in LAN?
Ans: In LAN network data is travelled via an
independent wire or telephone wire.
2. What is a Computer Network?
Ans; when more than one computer
is connected together and interact with each other via cabl or satellite they
form a computer network.
3. What are the advantages of Networking?
Ans:
1)
Resources
like printer, modem and hard disk can be share across network.
2)
Data and
information are always available on the net.
3)
Messages are
broadcast very quickly to all user connected with net.
4)
Ideas can be
shared on the net as and when required to solve a problem among users.
4. How does data travel from one computer to another in WAN?
Ans: First digital data is converted into analog
form by MODEM after which analog signal is travelled to different geographical
location using telephone wire or satellite. After reaching destination it than
convert analog to digital and information is used by target computer.
5. Describe the Network Topologies.
Ans: The different way in which
computers are connected to each other through Net is called Topology.
1. Bus
Topology: All the nodes and server are connected on a single bus.
2. Star topology: All computers are connected
to the main computer via independent wire or cable.
3. Ring
Topology: All nodes and servers are connected in such a fashion that they make
a structure of a ring.
