1.
The CPU stand for?
Correct Answer
A. Central Processing Unit
Explanation
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.
2.
ROM stands for?
Correct Answer
B. Read Only Memory
Explanation
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.
3.
RAM stands for?
Correct Answer
D. Random Access Memory
Explanation
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.
4.
ROM is a memory that is?
Correct Answer
B. Non-volitile
Explanation
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.
5.
RAM is a memory that is
Correct Answer
C. Volatile
Explanation
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.
6.
When an application fires up, the application is loaded into?
Correct Answer
B. RAM
Explanation
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.
7.
The CPU can be described like the:
Correct Answer
C. Brains of a computer
Explanation
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.
8.
When your computer slows down it is likely that you maybe:
Correct Answer
B. Running out of RAM
Explanation
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.
9.
The task manager is used to:
Correct Answer
A. Monitor processes on your computer
Explanation
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.
10.
Task manager is launched by:
Correct Answer
A. Cntl-shift-esc
Explanation
Try each of these operations to see which is the correct sequence to launch the Task Manager.
11.
Memory is measured in bytes. Which of the following statements is(are) correct.
Correct Answer(s)
A. 1GByte of memory is Greater than 1MByte of memory
B. 1GByte of Memory is approx the same as 1000MByte of memory
Explanation
1 GigaByte of memory is = 1000MegaBytes of memory
12.
The CPU is located on the...
Correct Answer
A. Motherboard of the computer
Explanation
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."
