What is the function of the operating system?

The operating system controls the hardware operation and interacts with driver programs and application software.

What are the two types of software?

The two types of software are system software and application software.

What is system software?

System software includes operating systems, utility programs, and driver programs that manage computer hardware and provide a platform for application software.

What is real-time processing?

Real-time processing processes data as soon as it is received, allowing for immediate responses but requiring large computing power.

What is batch processing?

Batch processing involves collecting data and processing it in groups at regular intervals instead of immediately.

What is parallel processing?

Parallel processing uses multiple processors to perform tasks simultaneously, either concurrently or by dividing a task into portions.

What does virtualisation do?

Virtualisation divides computer hardware into multiple virtual machines to run different operating systems and software.

What is the role of driver programs?

What is an example of mobile operating system?

iOS or Android.

What differentiates high-level languages from low-level languages in programming?

High-level languages are more user-friendly and easier to program, while low-level languages are closer to machine code.

What is the main advantage of using application software?

Application software allows users to perform specific tasks, such as word processing or photo editing.

What is the example of educational software?
