why we u use a ram in our computres ? without ram can we work?by using ram the time is wasting ? idontwant to

Answer 1

you have to have memory you can access to operate a computer. If you remove all the ram, you may as well unplug the computer also because it will no longer function.

By the way, your spell check isn't working.

Answer 2

RAM should be used in computers....
Because as you must be knowing that RAM is Random Access Memory.
i. e. the memory can be accessed randomly. However without it, it will be needed to access data from Hard Disk (i. e. secondary storage) which is serial access memory.

As the speed of the processor is very high it needs the pages of memory within fraction of seconds. And since RAM is randomly accessed it is used to achieve this task.

Without it Computer will no longer be a computer...since they are used to speed up the task.

Today the whole world is into getting a more faster computer and if we were not to use RAM then the competition will probably become stable.

Answer 3

Perhaps the most misunderstand concept amongst novice computer users/owners is the difference between RAM and Hard Drive space.

Knowing the difference becomes very important when trying to figure out why the latest and greatest "must have" software won't work on your computer. It also helps you figure out what needs to be done so it will work.

Hopefully this will answer the oft-asked question:

"It says I need 32MB RAM, but I have 800MB storage - that should be enough, right?"

Hard Drive

The Hard Drive may also be called "Storage" or "Disk Space" and it is measured in Megabytes (MB) or Gigabytes (GB).

A Hard Drive consists of a metal platter which spins very fast. As it spins, the hard drive "head" moves along the platter and can "read" and "write" information.

The hard drive is used for long term and large amounts of storage.

In your everyday life, when you "save" a file, you are asking the computer to "write" this information to the hard drive. There is normally a slight delay as the computer finds the right space on the hard drive and actually saves the information.

Once "saved", the information is magnetically encoded. As a result, it stays on the hard drive - regardless of whether you turn the computer off. The information stays there. And, later, you can erase your file and free up that space.

Advantages:
Relatively Cheap
Can turn off the computer, and reload the information later.

Disadvantages:
Since it's a mechanical device (spinning platter), it can be slow.

RAM

RAM may also be called "Memory" and it is measured in Megabytes (or MB).

RAM comes in the form of computer chips. These chips plug into special connectors in your computer. The purpose of these chips is to provide fast storage for the computer to use.

When the computer loads your file from your hard drive - where does that information go? It makes a copy of the information from the hard drive and places it in RAM.

Why? For speed. Information in RAM is stored based on electrical signals... so to change information simply requires sending a different electrical signal to the chip. This happens very quickly. Remember, the hard drive is a physical object that is spinning. It takes time to start it spinning, and move the hard drive "head" to the right position.

Let's say you are typing in a Term Paper in your Word Processor. Every key you press on the keyboard becomes part of your Term Paper. You don't realize it but, every letter you press has to be remembered by the computer. It accomplishes this by saving those keys in RAM. It happens so quickly, you don't even notice it.

So it's fast... but what happens when you turn off your computer? All the information is lost since the electrical signals storing the information have been turned off.

Advantages:
Fast

Disavantages:
"Forgets" when you turn the computer off
More expensive than hard drive storage.

Summary

So, as you can see, they are both necessary forms of storage and serve different purposes. Generally, a computer has far more Hard Drive storage than RAM. A typical computer one might purchase today might have 64 MB of RAM, and 2000 MB (or 2 GB) of Hard Drive storage.

For computer programs you purchase at the store: the minimum RAM requirements are usually less than the Hard Drive requirements. This is because programs will only load a small portion of information from the hard drive at a time. A good example of this is a game with many Levels. When you are playing on Level 1, there is no need to load any information (pictures, text) about Level 2 yet. However, all the information for Levels 1 through 30 need to be on the hard drive.


"It says I need 32MB RAM, but I have 800MB storage - that should be enough, right?"

So, it should be obvious now, that this person is comparing Apple and Oranges. He/She needs to see how much RAM their computer has to decide if they have enough.

Answer 4

RAM = Random Access Memory

Answer 5

a computer is a digital device and can understand only digital on/off signals. the storage media in computer consist of magnetic disks/ optical disks/ floppies/ hdd etc which cannot be directly understood by computers main processor as they are not digital signals. therefore the data in those storage media has to be transferred to computer understandable media which is done using RAM; i.e. Random Access Memory which consists of chips and stores machine understandable digital signals. thus any data to be processed from any storage media has to pass through RAM. We just cannot work without RAM.

Answer 6

All computers need RAM to work..

Answer 7

ram is the hear t of computer
it helps to boot the system
after processor it is the most important

Answer 8

RAM is an essential part of the computer, without it ur computer won't even start.

Answer 9

windows and the programs you use, load information into the ram that it needs to access quickly for better functionality. Like fonts and other tools that you use.

Answer 10

it is not possible to run a computer without a ram
