Computer Science Essentials for Grade 10

What is the primary function of the CPU?

• To store data permanently

• To provide power to the computer

• To manage network connections

• The primary function of the CPU is to execute instructions and process data.

Define the term 'algorithm' in computer science.

• An algorithm is a type of computer hardware.

• An algorithm is a programming language.

• An algorithm is a step-by-step procedure for solving a problem or performing a task.

• An algorithm is a random guess for solving problems.

What is the difference between RAM and ROM?

• RAM is non-volatile and used for permanent storage; ROM is volatile and used for temporary storage.

• RAM and ROM are both volatile and used for the same purpose.

• RAM is used for permanent storage; ROM is used for temporary storage.

• RAM is volatile and used for temporary storage; ROM is non-volatile and used for permanent storage.

Explain the concept of 'software' and 'hardware'.

• Software refers to the physical devices used in computing, whereas hardware is the code that operates them.

• Software is the hardware that stores data, and hardware is the software that processes it.

• Software is the intangible set of instructions that tells a computer what to do, while hardware is the tangible physical equipment that executes those instructions.

• Software is the physical components of a computer, while hardware is the software that runs on it.

What does the term 'network' refer to in computing?

• A single device that connects to the internet.

• A collection of interconnected devices that can communicate and share resources.
