Computer memory and had drive memory have become something that people have confused as the computer age progresses, although no truly technical person would ever get them up. Both hard drive space and the amount of random access memory a computer has can effect a system’s performance, but they affect it in different ways.

Computer memory is designed to be a temporary storage area for information that the computer needs while it is running. Information does not get permanently written to the memory chips and the computer only stores it for as long as it needs it. The hard drive and other disc drives are used for longer term storage of information.

The confusion between memory and hard drive space came about possibly when Windows instituted virtual pages. If the computer needs more memory, virtual pages function like the swap space on a Unix of Linux computer. The virtual pages use hard drive space to store information. The upside is that programs can run on computers that do not quite meet the computer memory requirements for the application. The downside is that doing so slows the speed of the computer and the application down.

Upgrading a computer memory in your system will improve speed, especially if you do not currently have enough memory to handle all the tasks you use your computer for on a regular basis. Adding memory is in many ways, like adding additional lanes to a highway that has become crowded or adding a new road system. The number of cars or pieces of data for the analogy, going in and out of the memory clog up the roadways. Put more roadways in and the cars have alternate paths. Removing the excess traffic lets the cars get to and from their intended destination more easily.

Putting in computer memory is relatively easy. The latest forms are DDR and DDR2. To install new memory, the user must have the type that his computer has the slots for. The DDR and DDR2 connections, although they are different versions of the same technology, do not have the same interface. The slots for the different types of computer memory are not interchangeable.

What is a computer memory chip and its function?

A computer memory chip is the device that replaced (in the early 1970s) the magnetic core memory in computers (that had been used since the early 1950s). Magnetic core memory replaced a variety of other forms of memory (e.g. Williams tube CRT memory, selectron tube memory, flood gun CRT memory, mercury delay line memory, magnetostrictive delay line memory, rotating magnetic drum memory, long shift register memory) used by earlier computers. Computer memory (of any type) serves the function of storing instructions and data inside the computer that it will need frequent and rapid access to.

What are two types of computer memory and their function?

The 2 types of computer memory are ROM and RAM. These stand for Read Only Memory and Random Access Memory, respectively. Read Only memory is the type of memory that is non-volatile, which means that the data contained here is never lost, even when the computer is shut down. RAM on the other hand is the type of memory which is volatile-- which can be lost the moment the computer is turned off. It temporarily just stores the data that's being processed when the computer is on.
