maryana noticed her computer is no longer as fast as it use to be when she purchased it a few months ago. she noticed that her computer is sluggish when she have several programs open. this is caused to her

random access memory

video card

motherboard

It is caused to her Random Access Memory RAM.

Explanation:

When a computer machine becomes slow on opening several programs this  signals to the problem than Random Access memory is lacking. It means an additional RAM is needed to speed up the process.

As not having enough RAM will make your hard drive to compensate hardly for the lacking memory. It is done by taking resources away from other program which result is slow speed of the system.

So Maryana's computer is short of RAM, she needs to add additional RAM or avoid accessing some unnecessary heavy programs.

I hope it will help you!

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.
