You're probably thinking of virtual memory.
It uses Hard Drive
The RAM is where programs and their data reside when they are in use. The RAM can accept inputs, and send and receive data from the CPU. It is the "work area" of the computer, while the hard drive is the "warehouse" where everything stays when not in use. "Virtual RAM" consists of areas of the hard drive used as temporary storage when the data exceeds the available space of the actual RAM.
its flows from Data to RAM through d cables and its been caried by the Busses
This happens automatically when you run out of RAM. This is the reason Game's advice at least 10GB space free on your Hard Drive. The PC uses the RAM and Cache, then the Hard Drive, then you'll get Blue Screen of Death Memory Dump.
True!
yes,Because the hard drive is for store files and folder and ram make computer run faster and more ram more faster.
Random Access memory (RAM). It only holds data while the computer is powered up.
You need a domain name, and a minimum of 10GB of hard drive space is recommended as well as 128MB of RAM. More hard drive space and RAM would allow for more efficient server.
The three most notable things that hard drive performance will effect is:The start up time of your computer. As the information need to run the OS must be transferred from the hard drive to the systems RAM.The start up time of programs.If you are using almost all of your RAM space the system will use your hard drive to store information normally keep in RAM. In this case your hard drive performance will effect your entire system, but more ram will correct this problem better then a faster hard drive.
TRUE
RAM (Random Access "Memory") stores information temporarily while the power is on. Hard Disk "Space" stores information permanently regardless of whether the power is on or off. Computer specifications usually specify RAM as system "memory" (like 2GB DDR2 MEMORY) and refer to Hard Disk storage as "Hard Drive(s)", system "storage", or "Disk Space" (like 320GB HARD DRIVE). Think of the Hard Drive as a storage shed and the RAM as the playground. The computer gets the programs/data from the hard drive and pulls them out temporarily into the playground for you to use, then stores them back in the shed when you are done.
Virtual memory is referring to the RAM and the temporary space used on the hard drive. The other definition is the file on the hard drive used to simulate RAM.
