What is an Operating System (OS)?

• A type of computer hardware

• A program that acts as an intermediary between a user of a computer and the computer hardware

• An application program like a word processor

• A specific type of CPU

• Hardware

• Application programs

• Network cables

• Users

Which of these is an example of an Operating System mentioned in the document?

• Microsoft Word

• Google Chrome

• Linux

• Adobe Photoshop

The evolution of Operating Systems has been driven by what factors?

• Only hardware improvements

• Only user needs

• Hardware improvements + User needs

• Software bugs only

In the first generation of operating systems (Gen 1), what was primarily used for I/O?

• Keyboards

• Touchscreens

• Punchcards

• Mouse

What was the key characteristic of Operating Systems in the second generation (Gen 2)?

• Multitasking

• Batch systems

• Real-time processing

• Distributed systems

Which type of OS allows multiple programs to be loaded into memory simultaneously, with the CPU switching between them if one needs to wait for an I/O operation?

• Batch Operating System

• Multi-Programming Operating System

• Single-User Operating System

• Real-Time Operating System

What is a key feature of Multi-tasking/Time-sharing Operating Systems?

• Each task waits for the previous one to complete

• They use multiple CPUs for true parallel execution

• They provide an illusion that all tasks are executing at the same time by quick CPU switching

• They are primarily used for scientific computations only

Which type of operating system has more than one CPU to increase system throughput by parallelizing processes?

• Multi-tasking Operating System

• Batch Operating System

• Multi-Processing Operating System

• Mobile Operating System

What is a "system call"?

• A telephone call made by the operating system

• A programmatic way for a user program to request the OS to perform tasks reserved for the OS

• A process of debugging a program

• A hardware interrupt signal
