This will be general as you asked for.
1.256mb sdram.

Ram is a type of interface between a program and the hard
drive it is used to speed up access,256 is the amount of
memory it can hold.ram works in conjuntion with your
pagefile(virtule memory).

2.40 gig hard drive
the hard drive is where everything on the computer is
stored.in this case 40 gigabytes of information.

This is the "main memory" in your computer, what we used to call many
years ago "core storage". It's where running programs reside, and
where their work space is. The CPU can read and write it very quickly.
You have 256 million bytes (MB=megabyte, one million bytes)which is
quite reasonable for most things you'd use the xp operating system
for.

That's your hard disk drive. That's used for long-term storage of your
programs and data files. Your disk can store 40 billion bytes. (GB =
Gigabyte, a billion bytes)

Anything in RAM disappears when you turn the computer off. Things on
the hard drive stay there whether the power is on or off. (So we call
RAM "volatile storage" and disk "non-volatile" storage.) That's why
you have to save your work before you turn off the computer. "Saving"
it simply means writing it to the hard disk.

I'm afraid the answer you got about RAM is not really correct or
precise. For an authoritative definition and explanation of computer
memory, go here:

As for the hard drive, the 2.4 gigabytes refer to its size. In today's
world, this is a very tiny, old hard drive. Here is another link to all
sorts of good information about computers, including RAM and hard
drives:

1 relates to the active memory (RAM = Random Access Memory) of the
computer (compare memory in your head) which is being used - in
hundredths of a microsecond - by the processor (CPU) - used for holding
instructions and active data of programs you are running and of the
system itself

2 is the long term storage on a magnetic disk - compare your filing
cabinet of documents to refer to and read into the memory in your head.
Used to store files more or less permanently when not in use. Access
times to it are measured in milliseconds - say a hundred thousand times
slower than RAM
