a) Time Bomb
b) Trojan
c) Mellissa virus
d) Worm
e) Macro virus
Answer: D)

8. What is the term used for identifying location
in a storage device?
a) A byte
b) A record
c) An address
d) All of above
e) None of these
Answer: C)
Explanation: The memory has specific locations in
the system and every program or every file is stored at a particular location
in the memory. This is also referred to as address in the memory.
9. Binary numbers need more places for counting
because
a) They are always big numbers
b) Any no. of 0's can be added in front
of them
c) Binary base is small
d) 0's and l's have to be properly
spaced apart
e) None of the above
Answer: C)
Explanation: In mathematics and digital electronics,
a binary number is a number expressed in the binary numeral system or base-2
numeral system which represents numeric values using two different symbols:
typically 0 (zero) and 1 (one).
10. Which command is used to delete everything in
a directory?
a) Delete
b) Del
c) Deltree
d) Move
e) None of these
Answer: C)
Explanation: In the disk operating system, the
files and sub directories are stored in a hierarchy. This hierarchy maintains
the addresses in the memory in a tree format and if the user wants to delete
those, then the whole tree is to be deleted by using the command Deltree.
11. Which is a unit representing the no bits of
discrete.
a) Baud
b) Byte
c) Bit
d) All of the above
e) None of the above
Answer: A)
Explanation: In telecommunication and electronics,
baud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols
per second or pulses per second. It is the number of distinct symbol changes
(signaling events) made to the transmission medium per second in a digitally
modulated signal or a line code.
12. What is the major purpose of creating a
backup?
a) Adding more components to your
network
b) Protecting data by copying it from
the original source to a different destination
c) Filtering old data from the new data
d) Accessing data on tape
e) None of these
Answer: B)
Explanation: Backup is the term used for the
process when the data is saved from being lost or corrupt. Basically, when a
backup is made, the data is copied from a source to another destination and in
case it is lost, the data can be restored from that location.
13. In a Computer ________ is capable to store
single binary bit.
a) Capacitor
b) Flip Flop
c) Register
d) Inductor
e) None of the above
Answer: B)
Explanation: In electronics, a flip-flop or latch
is a circuit that has two stable states and can be used to store state
information. A flip-flop is a bistable-multivibrator. The circuit can be made
to change state by signals applied to one or more control inputs and will have
one or two outputs.
