I want to know the difference between RAM and Hard Disk Memory and why some say I can't call my hard disk space: memory?

You need to get their definition of "memory". Computer memory by definition is where data is stored. Ask them what their definition of "memory" is. You may get one of the two following answers. These are both incorrect:
The following was extracted from wikipedia:
"Secondary storage (also known as external memory or auxiliary storage), differs from primary storage in that it is not directly accessible by the CPU. The computer usually uses its input/output channels to access secondary storage and transfers the desired data using intermediate area in primary storage.
The secondary storage is often formatted according to a file system format, which provides the abstraction necessary to organize data into files and directories, providing also additional information (called metadata) describing the owner of a certain file, the access time, the access permissions, and other information."
Long story short: SPEED! and you CAN call a PART of your HardDiskDrive(HDD) memory, you can also call it page file or virtual memory! your CPU has also memory and it's called cashe memory that is the fastest memory in your PC after that is RAM and then the PAGE FILE/VIRTUAL MEMORY. For further information on how they interact look above!

The Hard Disk Drive is where everything is stored like your Documents, Pictures, Videos and so on. Including the Operating System files.
The RAM which stands for Random Access Memory means when you run applications on your computer - there is a specific type of RAM on there. This uses the RAM to actually use the computer.
If you don't have a HDD then your computer will not turn on and if you don't have RAM your computer will not turn on also.
If you have limited RAM then you can add virtual RAM as well - Here is a link to my video on how to do this: My video on how to do this!! You should use this if you have less than 3GB or 4GB RAM so your computer will run faster.
So here is the summary:
Hope this helped you learn what RAM and HDD means. Thanks allot!!

some people will argue this question to no end... I along with every computer engineer, computer scientist i know, refer to them as different things, memory is for placing of information while it is in use (ram.) Storage is for keeping information long term
think of it this way, if you have a bunch of tax papers and you are filing taxes right now, you probably have all that information on your desk to quickly refer to it, because you are working on it. You may keep some investment information in a filing cabinet because your not always working on it that is storage, you will pull it out when your doing taxes to get information from them. When you are done with taxes you will put them all into the filing cabinet for your records.
i wish to also cite "memory" pg 311 of "Barron's Business Guides Dictionary of Computer and Internet Terms 8th Edition (c) 2003: "The space within a computer where information is stored while being actively worked on..." and many websites out there
if one where to call hard drive space memory, it is my educated opinion as a student in computer engineering that i am prepared to back up with reliable sources that that individual is incorrect in saying that.

I'm not an expert on it but I believe that when you use your hard drive as virtual the only time that it doesn't increase the performance of your computer is during boot up.
