• Peripherals

  Power

• Interrupts

  Scheduling

  Multitasking

• Memory Management

  Secondary Storage Management

  UI

  Software management

Answer explanation

The correct choice is Memory Management, Secondary Storage Management, UI, and Software management as they are essential functions of an operating system.

• Windows

• MacOS

• Arch linux

Answer explanation

MicroCore is a purely CLI based Operating System, making it the correct choice from the given options.

What are the benefits of RISC-V when compared to CISC based architecture such as x86

• RISC-V is more complex than x86 and therefore allows for faster processing

• RISC-V consumes more power than x86 but it is faster

• RISC-V has worse performance in all workloads compared to x86

• RISC-V is simpler than x86 but it is not yet faster than CISC based cpu's developed by intel even though this is the case RISC based cpu's are still cheaper and there is no reason for CISC based cpu's being faster other than then being developed more

Answer explanation

RISC-V is simpler than x86 but not yet faster than CISC based CPUs like Intel's. RISC CPUs are cheaper, and CISC's speed advantage is due to more development.

CPU:

Describe a way the OS of network workstation hides the complexity of the network from the user

• Single processor is mainly occupied with the OS jobs and might not be able to handle multiple jobs
  Rendering 3D graphics requires a great deal of processing (which a single processor may not be able to give)

• It does not waste storage on functions that are not needed
  
  Makes maximum use of the available (limited) memory to provide the features needed for the phone
  
  Ensures high level of security

• It assigns a block of memory to the program when the program requests for memory
  It would also reallocate memory when the program is not needed to free up memory space

• 1)Icon showing images on the user's desktop
  2)Connects to (part of) the server/printer
  3)Operating system runs this access in the background (device drivers);

Outline the Function of an interrupt

• An interrupt is used to speed up the processor's current task
• An interrupt is a signal sent to the processor to ignore all tasks
• An interrupt is a hardware component that enhances processor performance
• An interrupt is a signal sent to the processor to temporarily suspend its current task and attend to a higher priority task.

What is the difference between Polling and Interrupt

• Polling is a passive process, while Interrupt is an active process.
• Polling is faster than Interrupt.
• Polling involves actively checking for changes, while Interrupt is a signal sent to the CPU.
• Interrupt involves actively checking for changes, while Polling is a signal sent to the CPU.

In your opinion which is better CISC, RISC or ARM architecture?

Describe two issues result from a website being viewed on various devices, such as desktops and smartphones

• Screen size differences and performance optimization difficulties

• Cross-browser compatibility issues and search engine optimization challenges

• Inconsistent user experience and security vulnerabilities

• Content misalignment and slow loading times

Answer explanation

Screen size differences can lead to content misalignment, while performance optimization difficulties can result in slow loading times, making these the two main issues when viewing a website on various devices.
