Computer Fundamentals and System Concepts Questions
-
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.
-
large spreadsheets
-
large alphanumeric codes
-
large volume of numbers
-
only numbers
C
Correct answer
Explanation
A number crunching computer is designed to perform high-speed, complex mathematical calculations on large volumes of numerical data.
-
Super computers
-
Nano computers
-
Femto computers
-
Micro computers
B
Correct answer
Explanation
Nano computers are computers that are built at the molecular scale, often using nanotechnology to perform computations.
-
Output devices
-
Control units
-
Peripherals
-
ALU
C
Correct answer
Explanation
Peripherals are external devices that are connected to the CPU to provide input, output, or storage capabilities, such as keyboards, mice, and printers.
-
a system of technology without specification
-
a system or technology without locks
-
a well known technology of system
-
a non-proprietary technology or system

Correct answer
Explanation
Supercomputers perform calculations at extremely high speeds, typically measured in GFLOPS (Giga Floating Point Operations Per Second) or higher.
-
hardware device
-
software device
-
both (1) and (2)
-
none of above
A
Correct answer
Explanation
A modem (modulator-demodulator) is a piece of hardware that connects a device to the internet by converting signals.
-
Intel 80486
-
Intel 80586
-
Intel P6
-
None of Above
C
Correct answer
Explanation
The Intel P6 microarchitecture (Pentium Pro and later) introduced RISC-like features, such as translating complex x86 instructions into simpler micro-operations. The 80486 and 80586 (Pentium) are primarily CISC architectures.
