Computer Fundamentals and System Concepts Questions
-
copper
-
iron
-
silicon
-
granite
C
Correct answer
Explanation
Silicon is a semiconductor, which makes it the ideal material for manufacturing integrated circuits and computer chips. Its electrical properties can be easily modified to create transistors.
-
Central Programming Unit
-
Central Public Utility
-
Central Processing Unit
-
None of these
C
Correct answer
Explanation
CPU is the standard acronym for Central Processing Unit, the primary component of a computer that performs instructions.
-
vacuum tubes
-
transisters
-
IC chips
-
micro processors
D
Correct answer
Explanation
Fourth generation computers, emerging in the 1970s, are characterized by the use of microprocessors, which integrated thousands of ICs onto a single chip.
-
C:windowssystem32
-
c:system
-
c:Documents and Settings
-
C:windows
D
Correct answer
Explanation
The user data is a window system and the files are stored in window's folder.
-
transmitting computer
-
receiving computer
-
personal computer
-
all of the above
A
Correct answer
Explanation
A check figure, or checksum, is typically calculated by the transmitting computer and appended to the data to help detect errors that may occur during transmission.
-
auto-dialing
-
bulletin board
-
modem
-
terminal emulation
D
Correct answer
Explanation
Terminal emulation software allows a computer to act like a remote terminal, enabling it to communicate with a host system as if it were directly connected.
-
digital signals
-
analog signals
-
smoothly varying signal waves
-
both (2) and (3)
A
Correct answer
Explanation
Computers are digital systems that process and transmit information as binary values, represented by digital signals (discrete voltage levels).
-
host
-
address
-
domain
-
switch
-
with external access
-
acting as a backup
-
performing a file handling
-
switch
A
Correct answer
Explanation
A proxy server acts as an intermediary between a client and the internet, often providing external access, security, or caching services.
-
an embedded microprocessor
-
an extensive memory
-
an independent processing capability
-
a keyboard and a screen
D
Correct answer
Explanation
A dumb terminal consists primarily of an input device (keyboard) and an output device (screen). It lacks its own CPU or storage, relying entirely on a host computer for processing.
C
Correct answer
Explanation
The development of the first electronic digital computers, such as ENIAC, took place primarily in the United States during the mid-1940s.
-
IPS
-
CIPS
-
MIPS
-
Nano seconds
C
Correct answer
Explanation
CPU's processing power is measured in MIPS
-
nerve centre
-
master dispatcher
-
clock
-
all of the above
A
Correct answer
Explanation
The control unit directs the operation of the processor and coordinates the activities of other components, functioning like the nerve center of the computer.
-
chips
-
switching devices
-
circuits
-
components
B
Correct answer
Explanation
At its fundamental level, a computer is a collection of electronic switching devices (like transistors) that process binary signals to perform logic operations.
-
Electrical machine
-
Adding machine
-
Counting machine
-
Slide rule
B
Correct answer
Explanation
The ability to make logical decisions (if-then-else) distinguishes a computer from a simple calculator or adding machine, which only performs arithmetic.
