In this unit you will learn the differences between computer memory and computer storage. Memory and storage are important concepts to master in Information Technology. The two terms are often used interchangeably, so it is important to understand the key differences.
Examples of computer storage. Magnetic storage devices. Today, magnetic storage is one of the most common types of storage used with computers. This technology found mostly on extremely large HDDs or hybrid hard drives.
Main memory– This is the RAM that you see measured in megabytes when you buy a computer. Secondary memory — This is most often some sort of rotating magnetic storage that keeps applications and data available to be used, and serves as virtual RAM under the control of the operating system.
ter, or mass-storage host, is the computer that reads and writes to the storage media. Special-purpose mass-storage devices can function as mas- ters on their own and can also permit a PC or other USB host to func-tion as the master. If one master adds, deletes, or changes a file and the other master isn’t aware of the changes, confusion or worse problems can result. Devices that support two
backing storage. So you can see how a computer system uses two types of memory: Main memory holds all of the essential memory that tells your computer how to be a computer. Backing storage holds the information that you store on backup storage devices. Note: Memory is another term used for storage.
