a) Bus
b) Control unit
c) Semiconductors
d) A and b only
e) None of these
Answer: C)
Explanation: Semiconductors are crystalline or
amorphous solids with distinct electrical characteristics. They are of high
electrical resistance - higher than typical resistance materials, but
still of much lower resistance than insulators. They are used in making chips.
6. When are two devices in network?
a) When a process in one device is
able to exchange information with a process in another device
b) When a process is running on both
devices
c) When PIDs of the processes running
of different devices are same

one device is able to exchange information with a process in another device.
7. Which computer was considered the first
electronic computer until 1973 when court invalidated the patent?
a) ENIAC
b) MARK I
c) Z3
d) ABC
e) None of these
Answer: A)
Explanation: ENIAC (Electronic Numerical
Integrator And Computer) was the world’s first general-purpose computer. ENIAC
was designed and built for the United States Army to calculate artillery firing
tables. However, it was ENIAC’s power and general-purpose programmability that
excited the public’s imagination.
8. If more than one persons need to be connected
to a single central computer, which of the following is required?
a) Light pen
b) Mouse
c) Digitizer
d) Terminal

person.
9. The symbols used in an assembly language are
a) Codes
b) Mnemonics
c) Assembler
d) All of the above
e) None of the above
Answer: B)
Explanation: A mnemonic device, or memory device
is any learning technique that aids information retention in the human memory.
Mnemonics make use of elaborative encoding, retrieval cues, and imagery as
specific tools to encode any given information in a way that allows for
efficient storage and retrieval.
10. Web Pages are saved in which of the following
format?
a) http://
b) HTML
c) DOC
d) URL
e) None of these
Answer: B)

11. EDVAC is
a) Electronic Detected Variable
Automatic Computer
b) Electronic Discrete Variable
Automatic Computer
c) Electronic Discrete Valuable
Automatic Computer
d) Electronic Developed Valuable
Automatic Computer
e) None of the above
Answer: B)
Explanation: EDVAC (Electronic Discrete Variable
Automatic Computer) was one of the earliest electronic computers. Unlike its
predecessor the ENIAC, it was binary rather than decimal, and was a stored-program
computer.
12. A network where more number of users can be
added conveniently is known as _____?
a) Scalable
b) Dedicated
c) Decentralized
d) Secure
e) None of these
Answer: A)
Explanation: A scalable network means a network
connection which has the ability to handle more number of users as it currently
has without affecting its working capacity or efficiency.
13. The purpose of the _______ layer is to
transport a raw bit stream from one Machine to another
a) Physical Layer
b) Data Link Layer
c) Network layer
d) Application Layer
e) All of the above
Answer: A)
Explanation: In the seven-layer OSI model of
computer networking, the physical layer or layer 1 is the first and lowest
layer. This layer may be implemented by a PHY. The physical layer consists of
the networking hardware transmission technologies of a network.
14. Which of the following transmits analog
signals in multiplexing?
a) FDM
b) Synchronous TDM
c) Asynchronous TDM
d) Both 2 and 3
e) None of these
Answer: A)
Explanation: FDM is known as frequency division multiplexing.
In this technique, the total bandwidth is divided into several sub-bands. These
sub-bands are made on the basis of some particular frequency and transmits
analog signal.
15. Data are accumulated and processed in group
called
a) Batch Processing
b) Group processing
c) Time sharing
d) All of the above
e) None of the above
Answer: A)
Explanation: Non-continuous (non-real time)
processing of data, instructions, or materials. In data transmission, batch
processing is used for very large files or where a fast response time is not
critical. The files to be transmitted are gathered over a period and then send
together as a batch.
