What does memory enables a computer to do?

Answer 1

carry out a specific task

Answer 2

Depends on what type of memory you are talking about...

RAM or Hard Drive.

I'll explain both for you...

RAM is the equivalent to the 'short term memory' of our own brain. The more RAM a computer has, the more tasks it can run at the same time. RAM cannot store files permanently and as soon as you power down the computer everything stored in the RAM goes. Things like the operating system, background programs e.g. antivirus software, and programs such as word or internet explorer are all loaded into the RAM when you open them. In short the more RAM you have, the more you can do at the same time and the faster the computer can do it.

Hard Drive memory is the equivalent to the 'long term memory' of our own brain. The more HD (hard drive) space a computer has the more permanent files it can store. In general HD memory is much slower than RAM but when you shut the computer down the HD memory is retained. By adding a bigger HD you effectively increase the maximum storage area of the computer so you can keep more files, pictures, videos, etc... but this wont speed up your system.
