With their nearly similar definitions and functions, a RAM and a hard drive often get confused from each other. Although they are two of the most basic components of a computer, people still seem to find it difficult to distinguish a RAM from a hard drive. In this article, we’ll discuss the difference between RAM and hard drive.
What is a ram?
A RAM (Random Access Memory) is a temporary computer storage that requires an electric power to store information. This means that it has a volatile memory and all data will be lost if there’s no power. A RAM reads and writes data and continues to save memory as long as the system does not shut down.
what is a hard drive?
The hard disk begins to function as soon as the RAM stops. Therefore, it always comes bigger than RAM. RAM sizes may range from 256MB-32GB, and the hard drive’s accessible size may span from 500GB-8TB.
The hard disk lets the user store as well as erase data, and the user’s ability to store data depends on the size of space. All stored data on the hard disk does not clear during and after use. However, it does clear its data after a program is used.
In a nutshell, a hard disk is like a machine with different parts like the writer and the reader module while a RAM is a silicon chip that consists of circuits.
Increasing a computer’s storage
The RAM doesn’t allow the attachment of external RAM if it is short of memory. The hard drive will let you add another external hard disk so as to increase your disk space. You may also entirely change it and just add one with a higher capacity. You can ensure an increased storage capacity and less risk of data loss by having an external disk attached with your hard drive.
Identifying the difference between RAM and hard drive can really be confusing. However, with the right knowledge, you can easily learn the basics of their functions and ways on how you can get the most of what they can offer.
