You are testing out a new multi-tasking operating system. In your testing, you find that some applications are not getting sufficient CPU time while other applications are getting more than necessary. Which component is likely to be the cause of this problem?

Kernel

Explanation:

The kernel is software that constitutes a fundamental part of the operating system. It is primarily responsible for providing different programs with secure access to computer hardware. He is in charge of managing resources, through system call services. It is also responsible for deciding which program can use a hardware device and for how long, what is known as multiplexing. Accessing the hardware directly can be really complex, so the kernels usually implement a series of hardware abstractions. This allows to hide the complexity, and provides a clean and uniform interface to the underlying hardware, which facilitates its use to the programmer.

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
