Questions and Answers
- 1.
The CPU stand for?
- A.
Central Processing Unit
- B.
Central Periferal Unit
- C.
Central Processing Utility
- D.
Common Processing Unit
Correct Answer
A. Central Processing UnitExplanation
The correct answer is Central Processing Unit. The CPU is the primary component of a computer that carries out the instructions of a computer program by performing basic arithmetic, logical, control, and input/output (I/O) operations. It is often referred to as the "brain" of the computer as it interprets and executes instructions from the computer's memory.Rate this question:

ROM stands for?
- A.
Random Only Memory
- B.
Read Only Memory
- C.
Read Option Memory
- D.
Read Only Mapping
Correct Answer
B. Read Only MemoryExplanation
ROM stands for Read Only Memory. This is a type of computer memory that stores data that can only be read and not modified or erased. It contains permanent instructions that the computer uses during startup. The data stored in ROM is non-volatile, meaning it is retained even when the computer is turned off. ROM is commonly used to store firmware, which is essential software that controls the basic functions of a computer or device.Rate this question:

RAM stands for?
- A.
Real Access Memory
- B.
Random Access Mapping
- C.
Read Access Memory
- D.
Random Access Memory
Correct Answer
D. Random Access MemoryExplanation
RAM stands for Random Access Memory. It is a type of computer memory that allows data to be read from and written to in any order, regardless of the physical location of the data. This makes it faster and more efficient than other types of memory. RAM is volatile, meaning that its contents are lost when the power is turned off. It is commonly used as the main memory in computers, where it stores data that is currently being used by the computer's operating system, software programs, and data files.Rate this question:

ROM is a memory that is?
- A.
Volitile
- B.
Non-volitile
- C.
Flamable
- D.
Non-flamable
Correct Answer
B. Non-volitileExplanation
Read-Only Memory (ROM) is a memory that is volatile. It cannot be added to or taken away from. Programs that are stored in it are hardwired by the computer manufacturer.Rate this question:

- 5.
RAM is a memory that is
- A.
Corruptable
- B.
Non-corruptable
- C.
Volatile
- D.
Non-volatile
Correct Answer
C. VolatileExplanation
Programs move in and out of Random Access Memory (RAM) as programs are started up and closed. Consequently, it is a memory that is always changing in content i.e. it is volatile.Rate this question:

When an application fires up, the application is loaded into?
- A.
ROM
- B.
RAM
- C.
CPU
- D.
VDU
Correct Answer
B. RAMExplanation
When an application is fired up it is loaded into RAM. From there operations, calculations, etc. performed by the application will be processed from RAM by the CPU.Rate this question:

The CPU can be described like the:
- A.
Heart of a computer
- B.
Soul of a computer
- C.
Brains of a computer
- D.
Ears of a computer
Correct Answer
C. Brains of a computerExplanation
The CPU, or Central Processing Unit, is often referred to as the "brains" of a computer because it is responsible for executing instructions and performing calculations. It controls the overall operation of the computer, including processing data, managing memory, and coordinating tasks. Similar to how the brain is the central control unit of the human body, the CPU plays a crucial role in the functioning and decision-making of a computer system.Rate this question:

When your computer slows down it is likely that you maybe:
- A.
Running out of ROM
- B.
Running out of RAM
- C.
Have too much RAM
- D.
Have too much ROM
Correct Answer
B. Running out of RAMExplanation
if the amount of RAM a computer has is full, programs will run less efficiently as they can no longer be executed from RAM space where they are most efficiently processed by the CPU.Rate this question:

The task manager is used to:
- A.
Monitor processes on your computer
- B.
View files on your computer
- C.
To manage the boot process
Correct Answer
A. Monitor processes on your computerExplanation
The task manager is a tool that allows users to monitor the processes running on their computer. It provides information about the CPU and memory usage of each process, as well as the ability to end or prioritize certain processes. This helps users identify any resource-intensive or problematic processes and manage them accordingly. The task manager does not have the capability to view files on the computer or manage the boot process, making these options incorrect.Rate this question:

Task manager is launched by:
- A.
Cntl-shift-esc
- B.
Cntl-alt-esc
- C.
Cntl-esc-alt
Correct Answer
A. Cntl-shift-escExplanation
Try each of these operations to see which is the correct sequence to launch the Task Manager.Rate this question:

- A.
1GByte of memory is Greater than 1MByte of memory
- B.
1GByte of Memory is approx the same as 1000MByte of memory
- C.
1GByte og memory approx is the same as 100MByte of memory
Correct Answer(s)
A. 1GByte of memory is Greater than 1MByte of memory
B. 1GByte of Memory is approx the same as 1000MByte of memoryExplanation
1 GigaByte of memory is = 1000MegaBytes of memoryRate this question:

The CPU is located on the...
- A.
Motherboard of the computer
- B.
Washboard of the computer
- C.
The hard drive of the computer
Correct Answer
A. Motherboard of the computerExplanation
The CPU, or Central Processing Unit, is the main component responsible for executing instructions and performing calculations in a computer. It is located on the motherboard, which is the main circuit board that connects and controls all the other components of the computer. The motherboard provides the necessary electrical connections and communication pathways for the CPU to interact with other hardware components such as memory, storage, and peripherals. Therefore, the correct answer is "motherboard of the computer."Rate this question:
