types of computer storage devices

They used to be pretty expensive in the old days and are reserved for very specialized fast data storage. There are two types of storage devices used with computers: a primary storage device, such as RAM, and a secondary storage device, such as a hard drive. Definition of Magnetic Storage. Storage devices are also called secondary storage devices / backing storage devices / external storage devices or auxiliary storage devices. Pretty cool. Some examples are floppy disk, magnetic tape, CD and DVD. Why the heck do we need to have this distinction? Thus, tertiary storage is also known as nearline storage. In history, “memory” is also known as “core memory”, “main memory”, “internal memory” or “real storage”. Computers often rely on input/output (I/O) channels to access the secondary storage and transfer the desired data to the primary storage. The multiple-choice-questions? Below is a list of storage devices of computer of magnetic type: Floppy disk vs hard disk, which is more suitable for you? At the beginning of the 21st century, a kind of non-volatile floating-gate semiconductor memory known as flash memory became popular as offline storage. The deformities can be permanent (read-only media), formed once (write once media), or reversible (recordable or read/write media). So much that we can actually squeeze more than 1,000,000 “old school” disks into a single palm-sized gadget today. If your business works with big files such as large images, videos and programs, chances are that you will start running out of space eventually.
