c. The two components of the computer system are hardware and software.

d. Two examples of storage devices are a Hard Disk Drive (HDD) and a USB flash drive.

e. External storage devices are used for backing up important data, transferring files between different computers, and expanding the overall storage capacity of a computer.

QUESTION 14

a. Define the term RAM
RAM stands for Random Access Memory. It is a type of volatile computer memory that stores data and program instructions currently being used by the CPU for quick access.

I. Briefly explain the difference between ROM and RAM
RAM is volatile, meaning its data is lost when the power is turned off, and it is used for temporary storage of active data. ROM (Read-Only Memory) is non-volatile, retaining its data even without power, and typically stores permanent instructions needed for booting the computer.

II. Give two functions of RAM

• It stores data and instructions that the CPU needs to access quickly for current operations.
• It acts as a temporary workspace for running applications and the operating system.

III. Give two examples of application software

• Microsoft Word
• Google Chrome

b. Give two examples of social media tools

• Facebook
• Instagram
