Basic Computer Awareness MCQ Set 2 — 21 MCQ Practice
Which of the following represents the smallest unit of data processing time in a computer?
Out of the given choices, a picosecond is the smallest fraction of a second (10^-12 seconds), representing the fastest processing interval.
The ability of a computer to consistently produce the same results when given identical inputs is termed as:
Reliability implies that the computer will perform consistently and generate identical, error-free outputs when supplied with the exact same inputs and instructions.
A computer is free from monotony. This falls under which characteristic?
Being immune to the monotony of repetitive tasks is a core component of a computer's diligence.
Which asset of a computer enables it to recall any stored information instantly when requested?
The power of remembrance (or storage recall) allows a computer to retain and fetch any piece of stored data instantly, without forgetting it over time.
Data entering into a computer system is called input, while the structured result produced by the computer is called:
Output is the final structured result or processed information presented to the user after the input data has been manipulated by the CPU.
Why are computers considered to have "No Heuristics"?
Heuristics refers to the ability to learn from past experiences and improve. Standard computers do not possess this capability inherently and must be explicitly programmed.
The four basic functions of a computer system are:
The fundamental operational cycle of any standard computer architecture is comprised of input, processing, output, and storage (IPOS).
What type of device is a computer?
A computer is classified as an electronic device because it uses active electronic components (like microprocessors and transistors) to manipulate electrical currents representing data.
The performance of supercomputers is generally measured in:
FLOPS (Floating-point Operations Per Second) is the primary metric used to measure the computational capability of supercomputers running scientific applications.
What does FLOPS stand for?
FLOPS stands for Floating-point Operations Per Second, a key indicator of calculation capacity.
A computer cannot take any decision on its own because it lacks:
Without explicit program logic, a computer cannot make independent decisions because it lacks natural intelligence and common sense.
Which component of the computer is responsible for the actual processing of data?
The Central Processing Unit (CPU) is the hardware engine that interprets and executes program instructions to process data.
In computer science, data that has been verified, validated, and structured is known as:
Once raw data is validated, structured, and contextualized, it becomes valuable information.
The error rate in a computer system during normal operations is:
Computers operate with absolute logical precision; unless there is a hardware fault or bad input data, the internal calculation error rate is practically zero.
Which characteristic allows a computer to switch from scientific calculations to preparing an office payroll smoothly?
Versatility allows a single computer system to run entirely different software applications (like databases, spreadsheets, and media tools) seamlessly.
Once a program is loaded into memory, a computer can execute it without human intervention. This feature is known as:
Automation refers to the system's ability to execute a series of instructions on its own without requiring human input for each step.
Which of the following is considered the brain of the computer?
The Central Processing Unit (CPU) is commonly called the brain of the computer because it controls, coordinates, and executes all primary operations.
Computer speed was measured in milliseconds in which generations?
Milliseconds (1/1000th of a second) were the standard performance intervals for early mechanical, gears-based, and electromechanical relay machines.
The primary purpose of a computer system is to turn data into:
Turning unorganized data into structured, meaningful information is the primary purpose of any computing system.
Which characteristic implies that computers do not get tired, lose focus, or suffer from physical fatigue?
Diligence means the system can maintain high performance, processing accuracy, and focus indefinitely without getting tired.
A computer's IQ level is equivalent to:
A computer possesses zero natural intelligence of its own, meaning its native IQ level is strictly 0.
