What is the purpose of RAM in a computer?

• RAM is used to cool down the computer

• RAM is used to store long-term data in the computer

• RAM is responsible for printing documents

• RAM in a computer is used to temporarily store data and instructions that the CPU needs while it is actively processing tasks.

Explain the difference between hardware and software.

• Hardware are intangible components, software are tangible components.

• Hardware are virtual components, software are physical components.

• Hardware are physical components, software are programs.

• Hardware are programs, software are physical components.

Define the term 'algorithm'.

• A step-by-step procedure or formula for solving a problem or accomplishing some end.

Describe the role of a compiler in programming.

• A compiler is used to debug code in real-time

• A compiler translates high-level programming code into machine code that can be executed by a computer.

• A compiler converts machine code into high-level programming code

• A compiler is only necessary for web development

What is the significance of binary code in computing?

• Binary code is essential in computing as it forms the basis for all digital operations and data representation.

• Binary code is outdated and no longer used in modern computing.

• Binary code is only used in hardware, not software.

Explain the concept of abstraction in computer science.

• Abstraction in computer science refers to the act of making software more complex.

• Abstraction in computer science involves exposing all intricate details to the user.

• Abstraction in computer science is a physical process of removing unnecessary hardware components.

• Abstraction in computer science simplifies the programming process by focusing on essential aspects and hiding unnecessary details.

Define the term 'debugging' in programming.

• Debugging is the process of enhancing errors in a computer program.

• Debugging is the process of creating errors in a computer program.

• Debugging is the process of identifying and fixing errors in a computer program.

• Debugging is the process of ignoring errors in a computer program.

What is the difference between sequential and parallel processing?

• Sequential processing can handle multiple tasks simultaneously.

• Sequential processing is step-by-step execution, while parallel processing is concurrent execution.

• Sequential processing is faster than parallel processing.

• Parallel processing is only used for simple tasks.
