Many people confuse memory and storage. Memory is temporary. When you turn off the computer, everything in memory is lost. Storage is usually permanent. On most computers, storage also has far greater capacity than memory.
Most computers have several types of memory: RAM, virtual memory, cache memory, and ROM. Memory has many different names. It is called random-access memory – or just RAM – as well as primary memory. And sometimes, just to confuse things further, memory is called primary storage. This storage is in contrast to storage devices that are referred to as secondary storage, such as disks. Generally speaking, the more memory, the better. With most personal computers, the computer’s motherboard is designed so that you can easily add more memory – you just add memory chips. Most memory chips are now mounted on boards, and all you need to do is to plug the board into a slot on the motherboard. Adding more memory chips may be necessary to run large or graphics-intensive applications. RAM is fast, but it has one drawback, it is volatile – all the data disappears if the power fails.
Cache memory is a specialized chip used with the computer’s memory. Cache chips are faster and more expensive than regular RAM chips. The computer stores the most frequently used instructions and data in cache. Cache has a relatively small storage capacity but can significantly increase the system’s speed.
The instructions to start the computer are stored in read-only memory chips, which are not volatile. ROM chips are manufactured with instructions stored permanently on them. The instructions to start the computer are on a special chip known as a ROM BIOS (Basic Input/Output System) chip.
