How Do Operating Systems Work

How many calculations per second could early digital computers handle, compared to today's supercomputers?

• Early: 500, Modern: 34 billion

• Early: 5,000, Modern: 34 trillion

• Early: 50,000, Modern: 34 million

• Early: 500,000, Modern: 34 billion

How were programs typically written and fed into early digital computers?

• Through a keyboard and monitor.

• Using magnetic tapes.

• On punch cards.

• Via direct voice commands.

What is batch processing in the context of early computers?

• Processing multiple programs simultaneously.

• Feeding programs one at a time into the CPU.

• Running programs directly from a hard drive.

• Using a graphical user interface to manage tasks.

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

• To write programs specific to each machine's hardware.

• To manage and allocate computer resources, control hardware, and provide a user interface.

• To perform complex calculations at high speeds.

• To store all user files and documents.

When a program starts on a computer, how does the operating system (OS) facilitate its execution?

• It directly writes new code for the program.

• It translates the program into a different language.

• It provides a library of common commands and segments for the program to borrow.

• It connects the computer to the internet only.
