Answer:
Without it information flow is impossible
Explanation:
The word 'pivotal' also means crucial or vital, and so we need to consider what an operating system actually does.
Remember, merely having all the hardware of a computer would not allow you to run (install and use) programs. It is by means of an operating system that teaching programs can be installed, and it is also by means of an operating system learning can take place.
For example, a student can decode (learn) instructions/lessons from his teacher via a software program; and the software program needs an operating system to open (run) the program.
Answer: You need a temporary variable to hold the value 3
Explanation:
So, aList[0] is 3 and aList[1] is 19, if it will be as it is you litteraly say to the compiler to change aList[0] to aList[1] at this moment aList[0] is 19 and aList[1] also is 19 and if you try to change aList[1] to aList[0] it will not change its value because they are the same.
You need temp variable to keep one of the values.
Normal or random variations that are considered part of operating the system at its current capability are <u> c. common cause variations.</u>
Explanation:
Common cause variation is fluctuation caused by unknown factors resulting in a steady but random distribution of output around the average of the data.
Common-cause variation is the natural or expected variation in a process.
Common-cause variation is characterised by:
- Phenomena constantly active within the system
- Variation predictable probabilistically
- Irregular variation within a historical experience base
It is a measure of the process potential, or how well the process can perform when special cause variation removed.
Common cause variation arises from external sources that are not inherent in the process and is where statistical quality control methods are most useful.
Statistical process control charts are used when trying to monitor and control 5- and 6-sigma quality levels.
Answer:
The answer to this question as follows:
Explanation:
In option a, When we use fork, a new mechanism, that uses fork() method, which is in the parental process, to replicate all sites. It has been installed in a space-differentiating operating system.
In option b, It is the present system cycle that scan and wait for any of the system processor to be installed.
In option c, The time delay happens when A operates. It is a global that make issues, which are cleared and slowed down when an interrupt happens. In this process, there are not any distractions. It splits into slowly as it heads into the ISR. It helps to understand the code easily.
Change is what is left over
ex. the cashier tells you "here is your leftover change sir/ma'am "<span />
