Operating Systems & System Software

What is the main function of an operating system?

• To cook dinner, To play music, To write poetry

• To manage computer resources, provide a user interface, and facilitate communication between software and hardware.

Name three types of operating systems commonly used.

• Windows OS, macOS, Linux OS

• Android

• iOS

• Unix

List three components of system software.

• Operating systems, device drivers, utility programs

• Application software, Firmware, Middleware

What are the two main types of user interfaces in operating systems?

• Graphical Command Interface (GCI)

• Command Line Interface (CLI) and Graphical User Interface (GUI)

• Textual User Interface (TUI)

• Visual User Interface (VUI)

What are some common security features found in operating systems?

• User authentication, access control lists, encryption, firewalls, antivirus software, security patches

• Intrusion detection systems, network monitoring, data encryption

• Physical security measures, social engineering, data backup

Explain the role of memory management in an operating system.

• Memory management in an operating system is responsible for allocating and deallocating memory resources to processes, ensuring efficient utilization of available memory, preventing memory leaks, and handling memory fragmentation.

• Memory management is responsible for managing the CPU resources in an operating system.

• Memory management only allocates memory to processes without deallocating it.

• Memory management has no impact on preventing memory leaks or handling memory fragmentation.

Differentiate between single-user and multi-user operating systems.

• Single-user OS allows multiple users to access the system simultaneously.

• Multi-user OS restricts access to only one user at a time.

• Single-user OS is designed for shared use by multiple users.

• In single-user operating systems, only one user can use the system at a time, whereas in multi-user operating systems, multiple users can access and use the system concurrently.

How does system software differ from application software?

• System software is designed for entertainment purposes, while application software is used for system maintenance.

• System software provides a platform for running application software and managing computer hardware, while application software performs specific tasks for the end-user.

• System software is only compatible with Windows operating systems, while application software works on all platforms.

• System software is used by end-users, while application software is used by developers.
