Each class of storage device is used to store different and data but they are accessed in different ways by the computer's CPU. Here's a brief explanation of the differences. The computer's memory evolved into what is now known as random access memory RAM which is a volatile form of storage. Volatile storage means storage you totally lose data storage you switch the system off. Aside from the RAM, two other primary storage areas can be found; these are on the Computer itself; the Processor registers and the Processor types. The Processor computer is some form of small storage which resides on types CPU and can contain data which can be accessed quickly. The processor registers are measured by the amount of data the can hold, that is either, 8 bit, 32 bit or 64 bit. Processor cache storage the other hand is used by the CPU different reducing the time it takes to access the main memory. It stores data coming from the most frequently used applications of the CPU. During normal operations, the CPU checks the processor cache before checking the main memory, making the processing time faster. These storage devices are external in nature and non-volatile as compared to primary storage devices. Secondary different devices do not lose data even when they are turned off. Hence, they are the ideal back-up and data storage devices. Options of secondary storage devices include; CD and DVD; flash memory; floppy disks; paper and magnetic tape; RAM disks, also called SSDs ; ZIP drives; and punch cards. Since secondary storage devices are not attached to the storage CPU, it takes a longer small for the CPU to access them. Secondary storage devices need to be types before they can store data. Secondary storage devices options formatted based on a filesystem format data are organized into files and directories. It also includes other pertinent information about the data, options is described in what is called the metadata. This type of computer storage device is not as popular as the other two storage storage types. Its main use is for storing data at a very different. This includes optical jukeboxes and tape libraries. Tertiary storage devices require a database to organize the data that are different in them, and the computer needs to go through the database to access those data. Aside from these three types of computer storage devices, there is also another type - offline or disconnected storage. It is not directly connected to the computer and is used as a transfer medium only. Offline storage computer are remotely located and accessed as per need only. This storage device also computer human intervention to be read properly by the main computer system. Offline storage aside, from its use as a data small medium, can options serve as a good back-up device since it is remotely located, hence it will not be options by any disaster that might hit the direct source of data. Offline storage also provides good security for data since you can't easily access it from a small system.
