The brain of any computer system is ?
- A.
ALU
- B.
Memory
- C.
CPU
- D.
Control unit
- E.
None of the above
Correct Answer
C. CPUExplanation
The brain of any computer system is the CPU (Central Processing Unit). It is responsible for executing instructions and performing calculations. The CPU acts as the control center of the computer, coordinating and managing all the operations of the system. It interacts with other components such as memory, ALU (Arithmetic Logic Unit), and control unit to carry out tasks. The CPU is crucial for the functioning of a computer as it processes data and performs the necessary operations to execute programs and tasks.Rate this question:

Another name for all the parts of a computer.
- A.
Process
- B.
Hardware
- C.
Monitor
- D.
Software
Correct Answer
B. HardwareExplanation
The term "hardware" refers to all the physical components of a computer system, including the processor, memory, motherboard, hard drive, and peripherals. This includes all the parts that can be seen and touched, as opposed to software which refers to the programs and data that are stored on the computer. Therefore, "hardware" is the correct answer as it encompasses all the parts of a computer.Rate this question:

This memory is for short term storage and is lost when the computer is turned off.
- A.
Icon
- B.
CPU
- C.
Hard drive
- D.
RAM
Correct Answer
D. RAMExplanation
RAM stands for Random Access Memory, which is a type of computer memory that is used for short-term storage. It is volatile memory, meaning that its contents are lost when the computer is turned off. RAM is used by the computer to store data that is currently being used or processed by the CPU. It allows for quick access to data and instructions, which helps improve the overall performance of the computer. Unlike the hard drive, which is used for long-term storage, RAM is temporary and is cleared when the computer is powered off. Therefore, the given correct answer is RAM.Rate this question:

The part of a computer that allows the user to view information on a screen.
- A.
Mouse
- B.
Mother board
- C.
Monitor
- D.
Memory
Correct Answer
C. MonitorExplanation
A monitor is the part of a computer that allows the user to view information on a screen. It displays the output from the computer's graphics card, allowing the user to interact with the computer visually. The monitor is an essential component for user interaction and provides a visual representation of the computer's operation.Rate this question:

Computers use the ______ number system to store data and perform calculations.
- A.
Binary
- B.
Octal
- C.
Decimal
- D.
Hexadecimal
Correct Answer
A. BinaryExplanation
Computers use the binary number system to store data and perform calculations. The binary system is a base-2 system, meaning it only uses two digits, 0 and 1, to represent numbers. This is because computers use electronic circuits that can be either on (representing 1) or off (representing 0). By using the binary system, computers can easily represent and manipulate data using these two states, making it the most fundamental and efficient number system for computer operations.Rate this question:

Computations and logical operations are performed by the _______
- A.
Memory
- B.
ALU
- C.
Control Unit
- D.
Register
Correct Answer
B. ALUExplanation
The ALU (Arithmetic Logic Unit) is responsible for performing computations and logical operations in a computer. It is a crucial component of the central processing unit (CPU) and is designed to carry out arithmetic calculations (such as addition, subtraction, multiplication, and division) as well as logical operations (such as AND, OR, and NOT). The ALU receives data from the memory and registers, performs the required operations, and sends the results back to the memory or registers. Therefore, the ALU is the correct answer for this question.Rate this question:

A byte is a collection of _____
- A.
2 bits
- B.
4 bits
- C.
8 bits
- D.
16 bits
- E.
32 bits
Correct Answer
C. 8 bitsExplanation
A byte is a collection of 8 bits. In computing, a bit is the basic unit of information and can have a value of either 0 or 1. By grouping 8 bits together, we form a byte, which is commonly used as the fundamental unit of storage and data representation in computer systems. This allows for a wider range of values to be represented, as a byte can have 256 possible combinations (2^8). Therefore, the correct answer is 8 bits.Rate this question:

Primary memory is used by the
- A.
I/O devices
- B.
CPU
- C.
User
- D.
None of these
Correct Answer
B. CPUExplanation
Primary memory, also known as main memory, is a crucial component of a computer system that is directly accessible by the CPU. It is used to store data and instructions that are actively being processed by the CPU. I/O devices, on the other hand, use secondary storage such as hard drives or flash drives to store data. While users interact with the computer system, they do not directly use primary memory. Therefore, the correct answer is CPU.Rate this question:

Which of the memory is also known as main memory?
- A.
External memory
- B.
Primary memory
- C.
Secondary memory
- D.
None of these
Correct Answer
B. Primary memoryExplanation
Primary memory is also known as main memory because it is the main storage area in a computer system where data and instructions are stored for immediate access by the CPU. It is directly accessible by the CPU and is used to store the currently executing program and data that is actively being used. Primary memory is volatile, meaning that its contents are lost when the power is turned off. Therefore, it is the most important and fastest type of memory in a computer system.Rate this question:

What is the primary requisite of a good computer programmer?
- A.
Artistic mind
- B.
Mathematical mind
- C.
Scientific knowledge
- D.
Logical mind
Correct Answer
D. Logical mindExplanation
A logical mind is the primary requisite of a good computer programmer because programming involves problem-solving and logical thinking. Programmers need to analyze complex problems, break them down into smaller logical steps, and then write code to solve them. They must be able to think critically, identify patterns, and anticipate potential issues. While artistic, mathematical, and scientific knowledge can be beneficial in certain programming domains, a logical mind is essential for understanding algorithms, debugging code, and creating efficient solutions.Rate this question:
