What does RAM stand for?
- A.
Random Access Memory
- B.
Random Act Memory
- C.
Read Access Memory
- D.
Read Act Memory
Correct Answer
A. Random Access MemoryExplanation
RAM stands for Random Access Memory. This is a type of computer memory that allows data to be read from and written to quickly. Unlike other types of memory, such as Read Access Memory or Read Act Memory, RAM allows for random access, meaning that any piece of data can be accessed directly without having to read through the entire memory. Random Access Memory is essential for the efficient functioning of a computer as it provides temporary storage for data and instructions that are actively being used by the CPU.Rate this question:

What is the brain of a computer called?
- A.
CPU
- B.
RAM
- C.
ROM
- D.
USB
Correct Answer
A. CPUExplanation
The brain of a computer is called the CPU, which stands for Central Processing Unit. The CPU is responsible for executing instructions and performing calculations in a computer. It is considered the most important component of a computer as it controls and coordinates all the other hardware and software components. The CPU receives input from various sources, processes it, and produces output accordingly. It is often referred to as the brain of the computer because, like the human brain, it controls and manages all the operations of the computer system.Rate this question:

The speed of a CPU measured in? (Choose 2)
- A.
Gigabyte
- B.
Kilobyte
- C.
Megahertz
- D.
Gigahertz
Correct Answer(s)
C. Megahertz
D. GigahertzExplanation
The speed of a CPU is measured in Megahertz and Gigahertz. Megahertz (MHz) and Gigahertz (GHz) are units used to measure the clock speed of a CPU, which indicates how many cycles the CPU can complete in a second. A higher clock speed generally indicates a faster CPU, as it can execute instructions more quickly. Therefore, Megahertz and Gigahertz are the correct units for measuring the speed of a CPU.Rate this question:

What does CPU stand for?
- A.
Central Printer Unit
- B.
Central Processeing Unit
- C.
Centre Print Union
- D.
Centre Processing Unit
Correct Answer
B. Central Processeing UnitExplanation
The correct answer is Central Processing Unit. The CPU is the primary component of a computer that performs most of the processing inside the system. It is responsible for executing instructions and performing calculations, making it the "brain" of the computer. The other options, such as Central Printer Unit and Centre Print Union, do not accurately represent the acronym CPU and its function.Rate this question:

What are the two output devices in a pc?
- A.
Monitor
- B.
Keyboard
- C.
Mouse
- D.
Printer
Correct Answer(s)
A. Monitor
D. PrinterExplanation
The two output devices in a PC are the monitor and printer. The monitor displays visual information such as images, videos, and text, allowing the user to see what is happening on the computer. The printer, on the other hand, produces hard copies of digital documents or images, allowing the user to obtain physical copies of their work. Both devices play a crucial role in providing visual output and enabling users to interact with and share information from their computer.Rate this question:
