a. CPU uses 16-bit registers instead of its more efficient 32-bit registers to complete the process.

b. CPU uses chunks of ROM as if they were RAM.

c. computer swaps out nonessential parts of RAM to the hard disk, known as virtual memory.

d. application program cannot be run on that computer.

The answer is C.

Less frequently accessed data in RAM will be moved to hard disk.

Answer is C



The pc will have insufficient amount of memory when most of its memory is already occupied. WHY THIS HAPPENS? many reasons, like



1)OS is consuming more RAM than available for instance, Vista minimum requirement is to have at least 1~2GB of RAM to operate fine unlike XP which needs much less

RAM. e.g. 128MB.

2)many applications are opened at the same time. and there is no enough space on RAM.

3)virus or spyware



And the pc must use virtual memory if there were no such thing as virtual memory, then once you filled up the available RAM your computer would have to say, "Sorry, you can not load any more applications. Please close another application to load a new one." With virtual memory, what the computer can do is look at RAM for areas that have not been used recently and copy them onto the hard disk. This frees up space in RAM to load the new application



The read/write speed of a hard drive is much slower than RAM, and the technology of a hard drive is not geared toward accessing small pieces of data at a time. If your system has to rely too heavily on virtual memory, you will notice a significant performance drop. The key is to have enough RAM to handle everything you tend to work on simultaneously



IM me if need anything more, or when u get the right answer. whatever.

The answer is C - The computer swaps out nonessential parts of RAM to the hard disk, known as virtual memory.

e. user purchases an i7 processor with 24GB of Triple Channel RAM, which would run at 2000Mhz and have timings of 8-8-8-20. After this process, the user takes out the HDD(s) of the other computer in question and burns the remains of the "dinosaur."



The query then is to look for an application that could possibly use that amount of Random Access Memory.



(If you're looking for an answer above, I would have said c but e is such a better choice.)

Please pay attention in class.

This is one of the most basic IT questions.



Additional:

Read the chapter again, then.

There are only two answers that are even somewhat close. If you think about how computers drastically reduce in performance when running out of RAM then there leaves only one option. Why would a computer lose speed and run a program instead of just refusing to run it?



Must be C, obviously.

Take your condescending attitude and find a new hobby.
