What is the main difference between volatile and non-volatile memory?
Non-volatile memory is used for temporary storage
Volatile memory is more expensive than non-volatile memory
Non-volatile memory retains data even after power loss
Volatile memory is faster than non-volatile memory
Which type of memory is used during the computer's start-up process to initialise and bootstrap the system?
Random Access Memory
Hard drive
Cache
Read only memory
What is the main advantage of ROM (Read-Only Memory)?
It is faster than RAM
It is less expensive than other types of memory
It retains its data even when the power is turned off
It allows for dynamic memory allocation
What is the main disadvantage of ROM?
It is volatile and loses its content when the power is turned off
It offers less flexibility than other storage types
It has limited storage capacity
It is more expensive to manufacture than other types of memory
What is the main advantage of RAM (Random Access Memory)?
It retains its data even when the power is turned off
It is faster than most other types of storage
It provides a stable and reliable storage medium for critical system instructions
It is less expensive than long-term storage options
What is the primary purpose of RAM in relation to the CPU?
To store data permanently
To provide a stable reference for the CPU
To serve as a temporary storage space for actively running programmes and data
To retain essential system instructions
What is the main disadvantage of RAM?
It provides less flexibility than other storage types
It has limited storage capacity
It is volatile and loses its content when the power is turned off
It is more expensive than long-term storage options
1. (a) : Information or data that is entered into the computer system for processing.
2. (a) : The manipulation and transformation of input data by the computer's central processing unit (CPU) to produce output.
3. (a) : The result of processing input data. It can take various forms such as text, images, sound, or other forms of information.
4. (a) : Any physical component or peripheral attached to a computer, such as a keyboard, mouse, printer, or hard drive.
5. (a) : The physical components of a computer system, including the CPU, memory, storage devices, input devices, and output devices.
6. (a) : Programs and applications that run on a computer, providing instructions for the hardware to execute specific tasks.
7. (a) : The process of retrieving instructions or data from the computer's memory for execution by the CPU.
8. (a) : A base-2 number system that uses only two digits, 0 and 1, to represent all information in computers.
9. (a) : The process of changing data from one form or format to another, such as converting binary to decimal or vice versa.
10. (a) : The component of a computer that stores data and instructions for the CPU to access quickly. It includes RAM (Random Access Memory) and ROM (Read-Only Memory).
11. (a) : Volatile memory that temporarily stores data and program instructions that the CPU is currently using or processing.
12. (a) : Non-volatile memory that stores permanent instructions and data that do not change. It is used to store firmware and essential system instructions.
13. (a) : Another term for the decimal number system, which is a base-10 system that uses digits from 0 to 9.
