the suitable program and provide required data, computer does not need human
intervention. This feature is known as ___________.
(a) Accuracy
(b) Reliability
(c) Versatility
(d) Automatic
(e) No IQ
Explanation: Being Automatic is the
ability to do things without occupying the mind with the low-level details
required, allowing it to become an automatic response pattern or habit.
2. Personal
computers used a number of chips mounted on a main circuit board. What is the
common name for such boards?
(a) Daughterboard
(b) Motherboard
(c) Father board
(d) Childboard
(e) Newboard
Explanation: A motherboard is one of
the most essential parts of a computer system. It holds together many of the
crucial components of a computer, including the central processing unit (CPU),
memory and connectors for input and output devices.
3. Which of the
following is not the classification of computers based on operating principle?
(a) Electronic
Computers
(b) Analog Computers
(c) Digital Computers
(d) Hybrid Computers
(e) Both (b) and (c)
Explanation: Analog, Digital and
Hybrid are classification of computer based on operating principle.
4. Networking such
as LAN, MAN started from which generation of computers?
(a) First generation
(b) Second generation
(c) Third generation
(d) Fourth
generation
(e) Fifth generation
Explanation: The continued
improvement in fourth generation allowed the networking of computers for the
sharing of data. Local Area Network(LAN) and Wide Area Network(WAN), were
potential benefits, in that they could be implemented in corporations and
everybody could share data over it. Then the internet and World Wide Web
appeared on the computer scene and fomented the Hi-Tech revolution of 90's.
5. Which of the
following code used in present day computing was developed by IBM Corporation?
(a) ASCII
(b) Hollerith Code
(c) Baudot Code
(d) EBCDIC Code
(e) All of the above
Explanation: EBCDIC Code is a binary
code for alphabetic and numeric characters that IBM developed for its larger
operating systems. It is the code for text files that is used in IBM's OS/390
operating system for its S/390 servers and that thousands of corporations use
for their legacy applications and databases.
6. What is a
Pixel?
(a) A computer program that draws
picture
(b) A picture stored in secondary
memory
(c) The smallest
resolvable part of a picture
(d) All of the above
(e) None of the above
Explanation: A pixel is the smallest
portion of an image or display that a computer is capable of printing or
displaying.
7. A device that
not only provides surge protection, but also furnishes the computer with
battery backup power during a power outage is ______ .
(a) Battery strip
(b) UPS
(c) Surge strip
(d) USB
(e) Memory
Explanation: An uninterruptible
power supply, also uninterruptible power source, UPS or battery/flywheel
backup, is an electrical apparatus that provides emergency power to a load when
the input power source or mains power fails.
8. What is a
small arrow or blinking symbol i.e. a movable indicator on desktop is called?
(a) Logo
(b) Mouse
(c) Cursor
(d) Palm
(e) Hand
Explanation: A cursor is a movable
indicator on a computer screen identifying the point that will be affected by
input from the user.
9. ARP (address
resolution protocol) is ________.
(a) A TCP/IP
protocol used to dynamically bind a high level IP address to a low level
physical hardware address
(b) A TCP/IP high level protocols
for transferring files from one machine to another
(c) a protocol used to monitor
computers
(d) a protocol that handles error
and control messages
(e) All of the above
Explanation: The address resolution
protocol is a protocol used by the Internet Protocol (IP), specifically IPv4,
to map IP network addresses to the hardware addresses used by a data link
protocol. The protocol operates below the network layer as a part of the
interface between the OSI network and OSI link layer.
10. Which of the
following is a small microprocessor-based computer designed to be used by one
person at a time?
(a) Netbook
(b) Mainframe
(c) Supercomputer
(d) Personal
computer
(e) All-in-one
Explanation: Personal Computer (PC)
A microprocessor-based computer which is primarily intended to be used by one
person at a time. It is usually characterized by relatively low cost and small
physical size.
