What is the role of an Operating System in a computer?

• It coordinates all the operations of the computer.

• It is used for creating documents only.

• It controls the internet connectivity exclusively.

• It serves as an antivirus program.

Which of the following is a characteristic of Real-Time Operating Systems (RTOS)?

• They respond to inputs after a significant delay.

• They process and respond to inputs instantaneously.

• They are used primarily for gaming.

• They can only run one application at a time.

What is a benefit of Single User Single Task Operating Systems?

• They allow multiple users to operate simultaneously.

• They require more resources to run effectively.

• They are best used on devices with limited processing and memory.

• They are designed for complex multitasking.

Why would an office worker benefit from using a Single User Multitasking Operating System?

• It allows running only one application at a time.

• It requires fewer resources and is best for simple tasks.

• It enables the user to switch between applications quickly.

• It is best used where inputs must be processed and responded to immediately.

What is a primary advantage of Multi-user Operating Systems?

• They are optimized for gaming applications.

• They are designed for single users with high processing needs.

• They allow multiple users to share processing and resources.

• They are best for devices with limited processing and memory.

Which of the following is NOT a hardware factor affecting the performance of an operating system?

• Limited RAM Capacity

• Number of Cores

• Viruses

• Slow Hard Disk Read/Write (Fragmentation)

What is the role of a pagefile in the context of virtual memory?

• It is used to clean viruses from the system.

• It is a section of the hard disk reserved as an extension of RAM.

• It increases the CPU speed.

• It reduces the number of cores in the CPU.

Heavy use of virtual memory can lead to slower system performance because:

• It relies on fast working RAM data transfers.

• It does not use the hard disk at all.

• It relies on slow disk transfers rather than very fast working RAM data transfers.

• It increases the CPU speed automatically.

What is the role of the Operating System on a digital device?

• To manage the computer's hardware only

• To link between the hardware and the software

• To provide internet access

• To create backup facilities

Which of the following is NOT a function of the Operating System in terms of networking?

• Simplifying networking in a computer

• Implementing the TCP/IP stack

• Providing Network Utility Programs like traceroute

• Directly managing the company's financial transactions
