Question

what data does ram store apposed to hard disk?

Answer 1

RAM contains program executable code and variables which are currently in-execution on the computer. All data in RAM is lost when the machine powers off.



The hard disk is a storage space to keep the permanent copies of programs, and data files, including programs not currently running, and the operating systems own boot files (e.g. Windows system). Data is retained when power is lost, in magnetic records on the disk platters.



RAM is extremely quick, and it's very expensive, so there's not much of it, and it loses data when power fails, hence the need for Hard Disk storage. Hard disk storage is very slow to access and retrieve data by comparison, hence the need for RAM!

Answer 2

RAM stands for Random Access Memory when windows or other operating systems boot up they load off the hard drive and onto the RAM, RAM is much faster at accessing data than a hard drive



if you go online, play a game or type in word for example these programs are stored on the hard drive when you choose to open that applciation it is loaded into the RAM and then the computer uses RAM to access files, not all of a program loads onto RAM because it would take all of the RAM up just what is needed is loaded and then when you have used that part it is taken off the RAM



If all the available RAM is used up then windows and other operating systems will use virtual memory this uses the hard drive as RAM but is much slower (over 1 thouasand times slower) so a significant system lag will be noticeable



cache is what the processor uses as its immediate memory it is very similar to RAM but runs at the same speed as the processor data is loaded to the cache from RAM, graphics card or hard drive etc.. for processing



hope this helps with your query

Answer 3

RAM is data/memory directly accessible to the CPU/Motherboard through the front side bus. This memory is used to store running programs and associated variables.

The Hard Drive is used for Persistent data storage (When your computer is turned off and back on, the data remains) the hard drive is also used as a virtual Ram area when the main memory (RAM) is full. The Hard drive is much slower than RAM, Milliseconds vice Nanoseconds. RAM is erased when the computer shuts down.

RAM is controlled by a chipset on the motherboard known as the northbridge which is running at the Front Side Bus (FSB) which is at a high frequency 400,800,1000 MHZ.

Hard Drives are controlled by the southbridge chipset. This chipset is much slower 33, 100, 133, 200 MHZ and data throughput is shared with other devices, PCI, PCIe etc...



Hope this helps: Summary



RAM: Running programs and data for CPU

Hard Disk: Boot data, programs and data for later, virtual RAM.

Answer 4

What Does Ram Store

Answer 5

It holds the current programs (or sections of programs) plus data that is currently being used. It's much much quicker to access program instructions and data held in RAM than on the hard disk.

Answer 6

RAM is used whilst your computer is switched on and is the working memory.



All contents of RAM are lost when your computer is turned off.



RAM is basically for temporary storage whilst the hard disk is for permanent storage.

Answer 7

It stores your operating system and application files(eg when your loading a game or msn messenger)



When your out of ram it will use a piece of your harddisk as ram which is significantly slower, this is when your computer is slow increasing your ram will solve this.

Answer 8

RAM is working memory. Hard disks are storage.

Answer 9

the more RAM you have (random access memory) the faster your computer can work (randomly accessing different areas of your computer to make programs run)

Answer 10

ram is the memory that the proccessor uses.
