Types of Storage Devices for Computer

What are the types of storage devices for computers? The two main types of storage devices for computers are • The primary storage systems – • The secondary storage systems – Primary storage systems – These are the fastest types of storage devices for computer systems.

They include the cache memory and the Random Access Memory (RAM). They only hold data that is processing after which the specific data is returned to its original location or where it’s to be stored. For example, if a word document is to be edited, taking for instance it was in the flash disk,

IT will be loaded to the RAM for editing after which the edited document will be transferred to the flash disk. Secondary storage systems – These types of storage devices for computer systems have the ability to store data until the stored data is deleted.

The secondary storage systems can either be classified as sequential or direct depending on how data can be accessed from the storage media. The sequential types of storage devices for computer systems consist of magnetic tapes that are economically friendly besides being compact, reliable, and faster data retrieval and storage.

They are mostly preferred for a full backup. Currently, they are mainly used with mainframe computers. The direct access type of storage devices for computer systems is made up of optical disks, memory storage devices, and magnetic disks. The memory storage devices – The flash drives and memory cards are the only available memory storage devices.

They are portable and compact. Both come in different sizes. The memory cards come with their adaptors while the flash drives are connected to the computer system through USB ports. Other types of storage devices for computer systems that also come in a variety of forms are the optical disks which include; DVD / CD –ROM, DVD / CD –RW, and DVD /CDR.

These optical disks can either be classified as reading Only Memory where the data contained and never be erased instead it can only be read.
