What does POST stand for in terms of the Operating System boot process?
Power-on Self-test

Points will be deducted if you choose an incorrect answer(s).
- the App Store keeps a copy to redeem for macOS users.,
- macOS is not sold separately anymore, it comes with the Apple Mac Hardware you buy.
macOS is not sold separately anymore, it comes with the Apple Mac Hardware you buy.
Older versions can still be bought online at apple.com and redeemed via the mac app store.
Only the Operating System can interact with Drivers.
False
Everything from the OS to other devices can interact with the drivers of a device.
Memory (RAM) can: <select></select>
Points will be deducted if you choose an incorrect answer(s).
- Be saved to disk.
- Be cached in the CPU.
Select the components that make up a typical modern computer as defined in your textbook, Modern Operating Systems (Tanenbaum, A. 2014).
Points will be deducted if you choose an incorrect answer(s).
- Central Processing Unit
- Memory
- Disk Storage
A modern computer typically consists of one or more processors (CPU’s), Memory, disk storage (or storage memory), Input/output devices like touch screens, keyboards, a mouse, network interface devices etc.
What is one of the most common scheduling algorithms used by Operating Systems?
round robin
Round-robin is one of the algorithms employed by process and network schedulers in computing. As the term is generally used, time slices are assigned to each process in equal portions and in circular order, handling all processes without priority
Memory management allows the operating system to dynamically distribute memory across all running processes while ensuring optimal performance.
True
Memory management allows the computer or operating system to dynamically distribute memory across all running processes while ensuring optimal performance.
The CMOS is where the BIOS stores the date, time, and system configuration details it needs to start the computer.
True
The CMOS is where the BIOS reads information to start the BOOT process.
The operating system handles the device management for end-users.
True
The OS is responsible for device management.
What is Starvation when it comes to process management?
An overlooked Process that can run, but is never chosen
**Starvation ** is the problem that occurs when high priority processes keep executing and low priority processes get blocked for indefinite time. In heavily loaded computer system, a steady stream of higher-priority processes can prevent a low-priority process from ever getting the CPU. In starvation resources are continuously utilized by high priority processes. Problem of starvation can be resolved using Aging. In Aging priority of long waiting processes is gradually increased.
In which way(s) can a process be created?
Points will be deducted if you choose an incorrect answer(s).
- System Initalisation
- System Call
- User request
A program can have multiple sub-processes.
True
A computer program is a passive collection of instructions, a process is the actual execution of those instructions. Several processes may be associated with the same program; for example, opening up several instances of the same program often means more than one process is being executed.
What are the typical types of devices?
Points will be deducted if you choose an incorrect answer(s).
- Dedicated
- Shared
- Virtual
