[Tutorial ] Computer parts and what they do. [Memory/ram]
RAM stands forRandom Access Memory. It is what you are actually using at any one time. Let me try to explain it this way. Your brain has a conscience and a sub-conscience memory. The conscience memory is what you are using right now. The sub-conscience memory is what you will you need to remember something that happened a long time ago [this would be the hard drive/hard disk].
When you access your sub-conscience memory, then those memories are transferred to your conscience memory. Think of a computer in the same way. Thehard driveis the sub-conscience memory, so to speak. When your computer turns on, then what it needs to run your programs is then transferred to the RAM, or conscience memory of your computer.
When you are finished with a program or application, and you close the program, then it is wiped out of the RAM in order to make room for more applications, but it stays on your hard drive so you can recall it later. Same goes for when you turn off your computer. Eg. when you go to sleep.
