Solution 1
The windows operating system (referred as WOS) changes from one process to the
next through a context switch, which is the mechanism of storing and restoring the state or
context of the CPU in the Process Control block (PCB). Basically, it enables a running
process execution to be restarted from the similar point in future time. In this way, by using
this method, a context switcher allows multiple processes to stake one CPU. Hence, context
switching is an indispensable feature of a multi-tasking operating system (Le, 2018).
Solution 2
An interrupt is a kind of signal from a device, which is attached to a computer which
needs the operating system to halt as well as figure out what is to be done next. In
computer WOS, an interrupt handler, is often known as an interrupt service routine (referred
as ISR), is a block of code allied with an exact interrupt condition. In this way, an interrupt
handler is a low-level complement of incident handlers.
Solution 3
Out of the 3 basic operating systems include windows, Linux and mac, if I had a
customer who was new to PC systems, then following questions I would have asked him or
her to determine which operating system they should use as well as purchase (Schofield,
2016). These are the 3 main factors to be considered when someone new wants to purchase
new operating system:
1. Which are the main soft wares and applications those you want to run on your PC
system to do the specific job?
2. Questions related to hardware requirements and availability, flexibility, open source,
security as well as portability.
3. Which operating system you can afford easily?
