OOOOps. Thanks doll. I may be a nerd at heart but I'm a big technophobe. I don't know RAM from ROM.
And DOS stands for???
Deleted Operating Shit?
What does DOS stand for?Avarice said:ROM is the memory that stores part of the OS system for the bootup process. It's 'read only memory' I believe while RAM is your memory that you can delete and write to. I think ROM can't be manipulated.
I could be wrong (please techies correct me if I am) but I've only been in school for a month for computers now.It's DOS that we're working on now..
My head hurts. LOL.

What you should be looking at is the email header information (it has the route that the email took to get to you) it will have the names of the server it was sent from, and the various servers it passed through until it got to your server.
Here is a basic tutorial that explains the theory of how it is done.

Avarice, you're partially right with ROM being Read Only Memory, but the BIOS is no longer ROM as it used to be, it is now writeable FlashROM or EEPROMs (that way we can upgrade the firmware on the BIOS to fix or add features)

Thanks Ava!
Thank you.
Good luck in school! It's hard I know, been there before myself but the pay off are great!

Actual ROMs are pretty rare these days. The big advantage they have over EEPROMs is that they have a much lower power requirement and they are much faster.
a 'true' ROM is just about the fastest memory there is.
One place they are used is in calculators.
There's a new kind of memory, WOMs (write only memory) I think they use it to store blogs

but that would mean no one can read the blogs... I don't get it... I'm soooo confused, cause like just how does that there blogosphere work then?jjinvan said:There's a new kind of memory, WOMs (write only memory) I think they use it to store blogs
ok, ok... the ISP assigns the IP address... so... following strict word associations, one could say (uhhh, some might say) that, uhhh... semantically speaking... a reference to the "ISP address" is not (speaking anally) that, uhhh... untoward
Write Only Memory is for backup. It's mostly used in the financial industry to ensure that no data is lost and the system can retain the last record before the system crashes for any reason.OTBn said:but that would mean no one can read the blogs...

WOM was why the financial industry was able to bring the financial system back to the condition it was at on the morning of 9-11-2001. When a very large part of the system went down with the collapse of the WTC towers and the loss of the off-site-storage facilities in the WTC basements, the WOM backups allowed the system to be reset with every transaction at the point that it had been on 9-11.
It's the reason that we know some greedy bastards were trading airline stocks short in the hope of a huge payday. It's even known who they are.
Think about what happens when we record to a CD/DVD.
We use a WOM function to write the media because we don't want the heads moving around accepting read requests. Once the media has been recorded, it is now Read Only Memory because we don't want more written to it. (I'm ignoring the CDRW/DVDRW media because they can't be used as proof in court) The same thing is done in data warehouses. They use large arrays of Hard Drives configured as WOM. If the data is ever needed for recovery, the array is reconfigured as ROM.
