- A.
Central Processing Unit (CPU)
- B.
ROM
- C.
RAM
- D.
Hard Disk
Correct Answer
A. Central Processing Unit (CPU)Explanation
The correct answer is Central Processing Unit (CPU). The CPU is often referred to as the "brain" of the computer because it is responsible for executing instructions and performing calculations. It is the main component that carries out the majority of the computer's processing tasks, including controlling and coordinating the operations of other hardware components. The CPU consists of an arithmetic logic unit (ALU) and a control unit, which work together to process data and instructions. It is an essential part of the computer system and plays a crucial role in determining the overall performance and functionality of the computer.Rate this question:

RAM process information and instructions at different speeds measured in units called hertz (Hz).
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
RAM (Random Access Memory) is a type of computer memory that stores data and instructions that are currently being used by the computer. It does not process information or instructions at different speeds measured in hertz (Hz). The processing speed of a computer is determined by the CPU (Central Processing Unit), not the RAM. Therefore, the statement is false.Rate this question:

- 18.
Microprocessor measurement unit is:
- A.
Hz
- B.
Bit
- C.
Byte
- D.
GB
Correct Answer
A. HzExplanation
The correct answer is Hz. Hz stands for Hertz, which is the unit of measurement for frequency. In the context of a microprocessor, Hz refers to the clock speed or the number of cycles per second that the processor can execute. A higher clock speed typically indicates a faster processor, allowing it to perform more calculations or instructions per second. Therefore, Hz is the appropriate unit of measurement for a microprocessor's measurement unit.Rate this question:

Memory capacity and storage space measured in -----------------.
- A.
Bits and bytes
- B.
Hz
- C.
MHz
- D.
KHz
Correct Answer
A. Bits and bytesExplanation
Memory capacity and storage space are measured in bits and bytes. Bits are the smallest unit of information in computing and can represent either a 0 or a 1. Bytes, on the other hand, are a group of 8 bits and are used to represent larger units of data. By measuring memory capacity and storage space in bits and bytes, we can accurately quantify the amount of information that can be stored or processed by a computer system.Rate this question:
-
- 21.
Byte is group of ------------ bits.
- A.
Eight
- B.
32
- C.
255
- D.
One
Correct Answer
A. EightExplanation
A byte is a group of eight bits. In computer systems, information is stored and manipulated in binary format, where each bit represents a 0 or 1. A byte provides the basic unit of storage and processing, typically representing a single character or a small amount of data. By grouping eight bits together, the byte allows for a wider range of values to be represented, from 0 to 255. Therefore, the correct answer is "eight".Rate this question:

ROM is responsible for all of the following, except:
- A.
Starting computer
- B.
Checking system memory
- C.
Loading operating system
- D.
Processing data
Correct Answer
D. Processing dataExplanation
ROM, or Read-Only Memory, is a type of computer memory that stores data that cannot be modified or erased. It is responsible for several functions, including starting the computer, checking system memory, and loading the operating system. However, ROM is not responsible for processing data. Processing data is typically done by the computer's central processing unit (CPU), which retrieves data from other types of memory, such as random-access memory (RAM), and performs calculations or operations on it. Therefore, the correct answer is "Processing data."Rate this question:

Which memory is considered as a volatile memory?
- A.
RAM
- B.
ROM
- C.
CPU
- D.
Hard Disk
Correct Answer
A. RAMExplanation
RAM (Random Access Memory) is considered as a volatile memory. Volatile memory refers to a type of memory that requires constant power to retain data. RAM is volatile because it loses all stored data once the power supply is disconnected or turned off. This is in contrast to non-volatile memory like ROM (Read-Only Memory) or hard disk, which can retain data even without power. CPU (Central Processing Unit) is not a memory but rather the brain of a computer that performs calculations and executes instructions.Rate this question:

It is the main memory of PC and acts as electronic memory pool where your computer holds “working copies” of programs and data:
- A.
RAM
- B.
Hard Disk
- C.
ROM
- D.
CPU
Correct Answer
A. RAMExplanation
RAM stands for Random Access Memory. It is the main memory of a computer and acts as an electronic memory pool. RAM is responsible for temporarily storing and providing quick access to the "working copies" of programs and data that the computer needs to perform tasks. Unlike the hard disk or ROM, RAM is volatile memory, meaning its contents are lost when the computer is turned off. Therefore, RAM plays a crucial role in the overall performance and speed of a computer.Rate this question:

Byte is a single binary digit.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
A byte is not a single binary digit, but rather a unit of digital information that consists of 8 bits. Each bit in a byte can be either a 0 or a 1, representing a binary value. Therefore, the statement that a byte is a single binary digit is incorrect.Rate this question:
