The different types of computer memory can be confusing. Take a look at these pictures of RAM, ROM, flash memory and more to learn about what the various types of memory are up to in your computer.

Chances are good that your operating system includes virtual memory. It makes your computer act like it has a lot more RAM than actually it does. Find out what virtual memory is and how it increases the speed of your PC.

Removable memory has unchained us from our PCs -- we can now carry gigabytes of data wherever we go in a device the size of a matchbox. Learn about the three major digital storage technologies.

Like our brains, computers use both short-term and long-term memory to store data. But the similarities end there. There are several types of computer memory that are arranged based on both technical and financial concerns.
