What is true for computer's RAM?

January 8, 2017 at 21:26:19
Specs: Any, Any
I know this is a rather lame question, I've always used computers, but never understood what's running inside. I already read my textbook and can't seem to come to conclusion..

Which of the following statements about RAM are TRUE? Select all that apply.

a) Any part of RAM can be accessed at any time.

b) RAM is an area of a computer that holds programs and data that are waiting to be processed, to be stored on permanent basis, or to be output.

c) RAM stores information on permanent basis.

d) RAM stands for Read Acess Memory.

---
I said a to be true but only received partial credit. Which statements are true in this case? I know c and d are definitely not true because ram is only for temporary storage when the PC is on, so it's either between both a and b, or b, not a.
Any help is greatly appreciated!

And for those of you thinking I'm asking for you guys to do my homework. Please don't view it that way. The assignment is already turned in, graded and handed back to us with no feedback. I know c and d are definitely false, which means by logic, a and b must be true. I'm just having a difficult time understanding why b is considered true as well. The way its described for b fits as a definition of a hard drive because the hard drive is the one that stores programs that waits to be processed and thus stores these programs permanently, not the RAM.

You can think of RAM as the cache memory on your phone or the temporary download folder. The app on the phones stores your info so you don't have to log in or favorite something again and again. It stores relative information that helps programs run. Instead of loading all the files every time you want access it. Same goes for a video game console when a level is loaded it is stored temporarily there and your character only accesses the part you are using. Requires much less effort for the computer to process the input.

I don't need to be right, but I am never wrong.

I think you misread the question. (b) does not assert that anything is stored permanently in RAM.

If you get no feedback you should complain; you are not being taught properly.

"I know c and d are definitely not true"

You are only half-right there mate.

'c' is not true.

'd' is true (RAM stands for "Random Access Memory", of course that's true, what else did you think it stood for?).

There's loads of reliable information about RAM on the web, you shouldn't need to ask what it is (or what it isn't) on a forum.

The most annoying thing I see often is where people think that memory is the same as storage media or that storage media is memory, when they are two entirely different things.

The tech industry is partly to blame for this confusion (eg the name "memory cards" given to what are technically storage cards.

Except (d) said that RAM stands for "Read Access Memory", which is incorrect.

My complaint is with the idea that memory and storage media are
two entirely different things. They are both storage of information,
which is called "memory".

Along the lines of what ijack said, (b) is a better description
of short-term memory than it is of long-term memory.

"My complaint is with the idea that memory and storage media are two entirely different things. They are both storage of information, which is called "memory""

There are several different types of memory. The question posted by the OP specifically refers to RAM. Personally, I would not & do not refer to USB flash drives, SD cards, HDDs, SSDs, floppies, CDs or DVDs as "memory". They are either storage media or storage devices.

OK, can I add more confusion;

DRAM: Dynamic Random Access Memory (these days referred to as RAM), is a VOLATILE memory as it looses data when power is switched off or refresh cycles are stopped..

SRAM: Static Random Acces Memeory, is a VOLITILE memory that does not need refresh cycles and consumes very little power in idle mode. (used to store BIOS configurations etc).

NVRAM: Non-Volatile Random Access Memory, retains its data after power has been removed. Also known as flash-drives and alike.

A simple explanation is this:
Hard drive store the information but they are too slow to feed information into and out of the processor and would slow the entire process. Computers use RAM to load all of the information for both the data and all of the steps needed to process this data as well as the output from the process the data is then stored back onto the hard drive of just printed out as you see fit or as the program dictates. There are even faster very short term memory actually on the processor die and chip which helps the processor achieve even faster speeds but basically answer 'b' is True. 'c' is false, 'd' is the trick answer because if you do not read carefully you think it reads true. 'a' is only mostly or partially true since part of the RAM is being used for your operating system, background systems and running programs, these would be temporarily reserved and not accessible at all times for other things.

You have to be a little bit crazy to keep you from going insane.

RAM stores data temperately. After you shutdown your computer it erase the data
