What is the primary role of a computer's Central Processing Unit (CPU)?

• To store data for long-term access, even when the power is off.

• To render images, video, and animations for display on a monitor.

• To provide a temporary workspace for data that is actively being used.

• To execute instructions and perform calculations for computer programs.

Answer explanation

The CPU processes commands from programs, making it central to the computer's operation.

Which of the following best defines 'software'?

• The main circuit board that connects all the computer's components.

• Any device that is connected to a computer but is not part of its core architecture.

• A set of instructions, data, or programs used to operate computers and execute specific tasks.

• The physical components of a computer system, like the monitor and keyboard.

Answer explanation

Software is the collection of code and instructions that tells the hardware what to do.

The invention of the ______ was a major breakthrough that replaced bulky vacuum tubes and made smaller, faster, and more reliable computers possible.

• Floppy Disk

• Hard Drive

• Transistor

• Mouse

Answer explanation

The transistor, followed by the integrated circuit, allowed for the miniaturization and increased power of electronics.

What is the primary function of an Operating System (OS)?

• To protect the computer from viruses.

• To manage hardware resources and provide services for computer programs.

• To create documents and spreadsheets.

• To browse the internet and send emails.

Answer explanation

The OS manages memory, processes, and devices, allowing applications to run smoothly.

Random Access Memory (RAM) is considered 'volatile' because...

• Its contents are lost when the computer is powered off.

• It is very fast compared to a hard drive.

• It can be accessed in any order.

• It stores the computer's startup instructions.

Answer explanation

The term 'volatile' in this context means the memory requires power to maintain the stored information.

In programming, what is the purpose of a 'loop'?

• To store a value that can be used and changed throughout the program.

• To execute a block of code repeatedly as long as a certain condition is met.

• To make a decision and execute different code based on whether a condition is true or false.

• To find and fix errors within the code.

Answer explanation

Loops allow for the efficient repetition of tasks, such as processing all items in a list.

What is an 'algorithm'?

• A container for storing a piece of data.

• A mistake in a program's source code.

• A step-by-step procedure or set of rules for solving a specific problem.

• A programming language used for web development.

Answer explanation

An algorithm is a well-defined sequence of actions for accomplishing a task.

The concept of a 'digital footprint' refers to:

• The trail of data, both active and passive, that you leave behind when using the internet.

• The amount of storage space your files take up on a hard drive.

• The physical carbon footprint of running your computer and accessing the internet.

• A security feature that requires a fingerprint to log in to a device.

Answer explanation

This includes social media posts, Browse history, and other data collected about your online presence.

The process of finding and fixing errors in a computer program is called:

• Executing

• Compiling

• Deploying

• Debugging

Answer explanation

Debugging involves systematically identifying, analyzing, and removing 'bugs' or errors from code.

What is the function of a computer's motherboard?

• To perform all the calculations for the system.

• To act as the primary connection point for all hardware components.

• To provide the main workspace for data and programs in use.

• To provide long-term storage for files and the operating system.

Answer explanation

The motherboard holds and allows communication between the CPU, RAM, storage drives, and other critical components.
