Introduction to Operating Systems

What is the primary purpose of an operating system (OS)?

• To run hardware diagnostics

• To manage hardware and software resources

• To compile programming code

• To create user applications

Which of the following is an example of an operating system?

• Microsoft Excel

• Windows 10

• Adobe Photoshop

• SQL Server

What does multitasking in an OS mean?

• Running a single program at a time

• Simultaneous execution of multiple programs

• Creating multiple user accounts

• Running programs without an OS

Which of these is not a function of an OS?

• Process Management

• Memory Management

• Networking

• Antivirus Scanning

What is the role of an OS in file management?

• Creating a database

• Managing files and directories

• Designing file formats

• Encrypting files

What feature was introduced with third-generation operating systems?

• Batch processing

• Time-sharing systems

• Personal computing

• Cloud computing

Which of the following is true about the first-generation operating systems?

• They used graphical interfaces.

• They were based on vacuum tubes.

• They supported multitasking.

• They were designed for mobile devices.

Which of these is a characteristic of a monolithic OS?

• Strictly layered design

• All services run in a single address space

• Based on modularity

• Designed for real-time operations

What is a major benefit of the layered OS model?

• Enhanced user interface

• Easier debugging and maintenance

• Faster program execution

• Reduced memory usage

Micro-kernel architecture is designed to:

• Minimize the kernel size

• Run all services in kernel space

• Eliminate hardware dependencies

• Combine all processes in a single layer
