Two types of storage are in every computer: temporary and permanent. It’s like our brain: we can remember lots of things right away or we can use long term storage. But unless you commit the information to memory, you had better write it down, which is permanent storage. In a computer, temporary storage is provided by memory, or RAM (Random Access Memory). The more RAM your computer has, the smoother it operates and the more information you can “play” with at once.
Memory is also responsible of giving extra speed to your computer and, most of all, more stability. Nowadays, almost all computers are sold with at least 8GB of DDR3, which allows users to browse fast on the Internet and easily download and upload files to the cloud.
