Abstractions, Operating Systems and Software Licensing Review

What is the primary function of the hardware level in a computer system?

• To manage and coordinate system components

• To translate user actions into commands

• To provide physical components like the CPU and RAM

• To run application software and tools

What does a "single use" software license mean?

• The software can only be used by one person, on multiple devices.

• One person can use the software on one device.

• Multiple people can use the software on one device.
  

• The software is free to use and modify.

What does the application software level include?

• Operating System (OS) and device drivers

• Windows, icons, and menus

• CPU, RAM, and hard drives

• Word processors, web browsers, and games

1. Abstraction provides simplification by hiding complex details and ensuring that changes in one layer don’t disrupt the others, making systems more reliable and flexible.

• True

• False

What role does the user interface level play in computer systems?

• It interacts directly with the computer’s hardware.

• It allows users to interact with the computer through windows, icons, and menus.

• It manages memory allocation and process scheduling.

• It coordinates the communication between different layers of abstraction.

The _________software level acts as a bridge between hardware and application software, managing tasks like memory allocation and process scheduling.

• system
• Process

• Memory

• Access

What does a proprietary software license typically mean?

• The software can be freely shared, modified, and used by anyone.

• The software can only be used by one person on multiple devices.

• The software is paid and cannot be modified or shared.

• Multiple users in an organization can access the software simultaneously.

What does the system software level manage besides hardware functions?

• Memory allocation and process scheduling

• User commands and interface elements

• Physical components like CPUs and RAM

• Application-specific tasks like word processing

• Process Management is like a bouncer at a VIP party, checking permissions to ensure only authorized users can access certain data or system resources.

• True

• False

How does abstraction simplify the user's interaction with a computer?

• By removing the need for system software.

• By hiding the complexity behind a user-friendly interface.

• By providing a detailed view of the system's operations.

• By allowing users to understand complex hardware functions.
