All About Computer Memory

We would be lost without our computers. Businesses are able to operate, keep track of their inventory and order new supplies all through the use of computers. Personal computers keep track of our finances, allow us to surf the World Wide Web and provide ways to relax us through the use of video games. Computer memory is the most vital component that makes your computer run. Did you not know that? Do not feel bad because most computer users know just enough about their personal and work computers to know when something goes wrong. You can get ahead of the pack by this article. You can learn what computer memory is and how it affects the performance of your business or personal computer/laptop.

What is computer memory?

Computer memory is how your computer retrieves information. It starts with temporary storage and then moves from there. The more memory in temporary storage, the faster your computer will run. Think of it as this analogy: you save a phone number on a piece of paper near your phone. It is faster to look there then to have to go find the number again in a phone book. Computer memory works in the same fashion. Without the memory your computer would not run at all.

What is volatile storage?

Volatile storage is any storage or items that were temporarily stored that will be cleared when you power down your computer. RAM is cleared each time you power your computer down and volatile storage acts in the same manner. It is the opposite of non-volatile storage where information is permanently saved to the hard drive of your desktop or laptop computer.

What is Random and Sequential Access?

Random access is the ability of the computer to draw on different storage randomly. The data does not have to travel a set path in order to be stored or accessed. Sequential access is the direct opposite. There must be a set data path in order for the computer to be able to access the information it needs in order to run properly.

Can the information found in a computer memory be changed?

Yes, information found in a computer's memory can be changed. RAM is deleted and cleared whenever you restart your computer. Long term storage can be deleted and changed to meet your specifications. If you do not know how to change your data, you can always seek out message boards specializing in data storage.

How is memory stored?

Memory is first stored in the primary storage. This is the most accessible memory that is short term. If this memory or RAM is used up the computer will begin to slow down as it has to access more long term memory bank and so most people rely on a larger RAM as they want their computer to run faster. The memory is stored by the processor who decodes the lines of code. It will keep the information stored so that the computer can access it much faster when it needs it.
