in A nutshell, Hard Disk is used to Store Data, The Data gets written and once saved even if power goes off it will remain on the Hard Disk. (All your Documents, Files, music etc.) The Problem with the hard Disk is that its Way too slow in Reading a writing to acomodate a Operating Systems Fuction. Thik about waiting an hour or so for windows to boot, and feeling as if you were in the slowes computer ever. This is where RAM (Random Access Memory) comes in. Now RAM is very very fast in accessing Data, and while the data is loaded in RAM working on that data is a breeze. So when your Computer Boots its actually loading the Operation System onto RAM from your hard Disk and that's what you are working on, Same with any application, it loads onto RAM and that's how it works seamless without LAG ( most of the time :) ). Once you decide to save a file it then gets written onto the hard Disk again. Now Everything in RAM will be lost once the power goes off unless it was Saved.

ram stores instructions and a hard - disk stores data
No

RAM and Hard Disk both are memory storage devices. Which OS you have on the machine in question ? Gabriel winadmin.co.uk
Your Hard Disk is where programs and data are stored for later retrieval ( excluding virtual memory) . If a program is in execution it has to be loaded in the memory (by memory I mean the RAM), So your Java Heap has to be in the RAM and cannot reside on the Hard disk.
The amount of RAM has nothing to do with the size of your hard drive.
DVD and RAM are not permanent storage devices.
Disk caching improves the time it takes to read and write from a hard drive. A disk cache is essentially RAM that is built into your hard drive.
RAM is Random Access Memory. It holds open programs and files. The more programs and files that you have open, the slower your computer gets. When you save a file, the program stays open on RAM, but the file gets saved to the Hard Drive. ROM is Read Only Memory. It is memory that is hard to change, modify, and update. SSD - Solid State Drive. Solid State drives stores/transfers files at a faster rate than Hard Disk Drives. They are also less volatile than HDD's. HDD - Hard Disk Drive. A Hard Disk Drive stores your files on a hard disk. It is slower than an SSD and is more volatile than SSD too and should avoid magnets. Hope this helps
I'm not sure what you mean. If you mean 8 gigabyte Hard disk, yes, that's sufficient. If you mean 8.75 RAM, maybe. RAM and Hard disk are different things. RAM is memory that is volatile - it's deleted when you switch your computer off. The hard disk is non-volatile: It stays there forever, until you delete it.
RAM is "random access memory", often simply called "memory". It is basically where running programs and the data they need are stored. RAM is faster to access than hard disk space, but it is volatile - if the computer is turned off, the contents of RAM are lost. If you "run" a program, it is first copied from the hard disk to RAM. If you open a Word document, it is also copied from the hard disk to RAM. Any changes you do are done in RAM. If you "save" the document, it is copied back to the hard disk (for long-term storage).
