Even though computers are good, they can fail, so it’s a good idea to have a copy of your data. Secure storage of data is therefore an essential element of computer technology. That’s where computer storage devices come in. These are tools that allow you to store data, which can then be stored for a certain amount of time. There are primary and secondary storage devices and in these categories there are several types.
The RAM or RAM of a computer is considered a primary storage device. This is actually a computer area where the currently used data and applications are stored so that the processor can easily view them. However, the data stays in RAM only when the computer is turned on. Data is lost when the computer is turned off, but it can be recovered from the hard drive once the computer is turned back on.
Secondary storage devices are the ones you know best. The data remains on the device, even when the computer is no longer turned on. These include hard disks, floppy disks, compact disks, DVDs, and USB drives.
Hard Drives: Data is stored on the hard drive in a digital format. The hard drive is usually a component of the computer. However, external hard drives are also available. These have become extremely popular as they are outside of the computer. As a result, external disks are unlikely to be compromised like internal hard disks.
Diskettes: These are small storage devices made of a thin circular magnetic film. At the beginning of the computers, the diskette required a floppy disk drive and the data was recorded on the magnetic film. However, with the evolution of computers and storage devices, floppy disk has become less popular. In recent years, it has been replaced by USB keys and CDs much more powerful and practical.
Compact Discs: Originally created for storing audio recordings, CDs are now widely used to store multiple types of data. In terms of storage capacity, CDs can contain more than 600 MB of data. The information is stored in an optical format and can be stored for a very long time. CDs work with the computer’s CD-ROM drive.
Digital video discs, better known by the acronym DVD, are storage devices that became popular in the 1990s. They look a lot like CDs, measure about the same thing, and are also optical discs. However, in terms of storage, DVDs are ahead because they can hold up to seven times more data than a CD.
A USB flash drive is a portable memory chip. It is also called USB key or USB key. USB is a very handy tool and has become extremely popular over the last ten years because of its portability. However, its main asset is perhaps its storage capacity. surpassing all others, there are flash drives capable of holding up to 64GB of data. In addition, he does not use batteries; it just uses the power of the computer to work.
These are just a few of the available storage devices. There are others, such as memory cards, Blu-ray discs, and so on. However, as technology continues to evolve, do not be surprised when news is available.
