Explain the components of a CPU, types of computer storage, and types of computer output.

Here are the answers to Question 1 and Question 2.

QUESTION 1:

a) List the components of CPU
The main components of a CPU are the Arithmetic Logic Unit (ALU), the Control Unit (CU), and Registers. The ALU performs arithmetic and logical operations. The Control Unit manages and coordinates the CPU's operations. Registers are small, fast storage locations within the CPU that hold data for immediate processing.

b) Describe three (3) types of computer storage

1. Primary Storage (RAM): This is volatile memory used by the CPU to store data and instructions that are currently being used. It offers very fast access but loses its contents when the power is turned off.
2. Secondary Storage (Hard Disk Drive - HDD/Solid State Drive - SSD): This is non-volatile storage used for long-term data retention. HDDs store data magnetically on spinning platters, while SSDs use flash memory, offering faster performance and greater durability.
3. Optical Storage (CD/DVD/Blu-ray): These are portable, non-volatile storage media that use lasers to read and write data. They are commonly used for software distribution, media storage, and backups.

c) Describe four (4) types of computer output

1. Visual Output: Information displayed on a screen, such as text, images, and videos. Examples include monitors and projectors.
2. Audio Output: Sound produced by the computer, such as music, speech, or system alerts. Examples include speakers and headphones.
3. Print Output: Physical copies of digital information on paper or other materials. Examples include documents, photos, and labels produced by printers.
4. Tactile Output: Physical feedback that can be felt, often used to enhance user interaction. Examples include vibrations from game controllers or haptic feedback from touchscreens.

QUESTION 2:

a) Describe how to perform the following operations:

I. Creating Files and Folders
To create a new file or folder, navigate to the desired location in File Explorer. Right-click on an empty space, select "New" from the context menu, and then choose "Folder" or the desired file type (e.g., "Text Document"). Type a name for the new item and press Enter.

II. Renaming Files
To rename a file, select the file in File Explorer. You can then either right-click the file and choose "Rename" from the context menu, or click the file name once (after it's selected) to enter editing mode. Type the new name and press Enter.

III. Copying and Moving Files
To copy a file, select it, right-click, and choose "Copy". Then, navigate to the destination folder, right-click an empty space, and choose "Paste". To move a file, select it, right-click, and choose "Cut". Then, navigate to the destination folder, right-click an empty space, and choose "Paste". Alternatively, you can drag and drop files while holding the Ctrl key to copy, or just drag and drop to move.

IV. Deleting Files
To delete a file, select the file in File Explorer. You can then press the Delete key on your keyboard, or right-click the file and choose "Delete" from the context menu. The file will typically be moved to the Recycle Bin.

b) List five (5) desktop icons and their functions

1. This PC (or My Computer): Provides access to all drives, folders, and devices connected to the computer.
2. Recycle Bin: Temporarily stores deleted files and folders, allowing them to be restored if needed.
3. Web Browser (e.g., Chrome, Edge): An application used to access and view websites on the internet.
4. Network: Allows users to view and manage network connections and shared resources on a local network.
5. Documents Folder: A default folder for storing user-created documents, files, and other personal data.
