What is the drive for?

Disks are different: hard, local, CD, DVD, etc. Determining the purpose of each of them is difficult, but necessary. Because the age of technology requires it. So why do you need a disk?


The hard drive is located in the system unit of the computer. What is a hard disk in a computer for? All information, the operating system and all programs are stored on the hard disk. On the computer, we see the information that is stored on the hard disk in the item “My Computer”: “Local disk C”, “Local disk D”.

Local drives

The hard disk is divided into sections: “Local disk C” and “Local disk D”. You can store programs, files, movies, music, etc. on the disks. But, if there is a C drive, why do we need a D drive? The fact is that if the operating system is damaged by malware, all files are damaged. To adjust the normal operation of the computer, you have to reinstall the operating system. All that was stored on the local drive C, can not be restored. Therefore, you need a disk D, you can save information on it in case of reinstalling the OS.It is recommended to keep the most important files and archives on disk D to avoid the risk of losing these documents.

CD, DVD, blu ray and more

All of the above are quite tangible things, unlike local drives. Such discs are made in the form of a plastic disc, with a hole in the center. To determine what the above disks are necessary for, it is necessary to deal with them separately.

CD - CDs. There are two types of CD-R, record information, which is possible only once, and CD-RW, record information, which is possible several times. Memory capacity up to 900 MB (90 minutes of recording).

DVD - digital multipurpose discs. There are three types: DVD-R, DVD-RW, DVD-RAM. The purpose of such disks is very simple. They are needed to store information: audio, high quality video, various files and documents. DVD-R cannot be rewritten at all. DVD-RW can be rewritten up to 1000 times. DVD-RAM can be rewritten at all up to 100 thousand. time. DVD capacity is 17 GB. DVDs are more reliable than CDs.

Blu Ray (BD) - optical discs are relatively new standard. Such disks are needed for storing large amounts of information (the most common is up to 50 GB), including for storing high-quality audio and video.Rarely, there are BD disks with a capacity of up to 320 GB. They are also divided into several types: BD-R, which can be recorded once, BD-RE can be recorded repeatedly, BD-RE DL can be recorded repeatedly up to 50 GB.

Cleaning disc

A cleaning disc is needed to clean the lenses of various players and disk drives. And this, in turn, is necessary so that the disks “do not slow down,” and viewing information from them does not turn into a very difficult process. A cleaning disc is sold complete with cleaning fluid, and there is a brush on the disc itself.

What is the driver disk for?

These discs contain software that, if installed on a computer, can access the hardware of the device for which this driver is intended (webcams, scanners, cameras).
