Give some examples of secondary storage
Internal phone storage, SD cards, SSDs and hard drives. Phones mainly use internal flash storage.
What is the primary function of OS in this topic?
The main function is to act as an intermediary between user and computer hardware, managing resources like memory and storage so software runs smoothly
What happens when a phone runs out of available RAM?
The OS has to free or manage memory, which can cause background apps to close/reload and make the phone feel slower.
Does clearing your phone’s secondary storage give you more RAM?
No. Clearing storage does not directly increase RAM, because RAM and secondary storage are separate types of memory.
How can you stop the RAM from slowing down ?
Close unnecessary apps and restart your phone occasionally to free up RAM. Avoid running many demanding apps at the same time.
Is it true that with increased number of apps, the CPU’s clock speed decreases?
True
How is the concept of virtual memory involved in this topic?
- Not enough space in RAM
- RAM needs more storage/space to store data
- Secondary storage is used(HDD)
Give advantages of using multi core processing
It allows a phone to handle multiple tasks at the same time, improving performance and multitasking. It can also make demanding apps run more efficiently.
Why does an OS need to manage computer memory (RAM)?
ensures each running program has enough memory to function without interfering with or crashing other programs.
