This article will explain in detail what the computer disk refers to. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

A computer disk is the external memory device of a computer, that is, a circular magnetic disk is installed in a square sealed box in order to prevent scratches on the disk surface and lead to data loss; that is, a computer information carrier that can be rewritten repeatedly.

The computer disk is the external memory device of the computer, that is, the circular magnetic disk is packed in a square sealed box in order to prevent the surface of the disk from scratching and causing data loss. To put it simply, it is a kind of computer information carrier that can be rewritten repeatedly.

Disks can be divided into floppy disks and hard disks:

Floppy disk (Floppy Disk) is the earliest removable medium used in personal computer (PC). Floppy disk reading and writing is done through floppy disk drive, and has now been replaced by USB disk.

Hard disk is one of the main storage media of computer, which consists of one or more aluminum or glass discs. The disc is covered with ferromagnetic material. Hard drives include solid state drives (SSD, new hard drives), mechanical hard drives (HDD traditional hard drives), and hybrid hard drives (HHD, a new hard disk based on traditional mechanical hard drives).

This is the disk that often appears on computers now.

The difference between disk and hard disk:

First, the nature is different

1. Disk property: a memory that uses magnetic recording technology to store data.

2. The nature of hard disk: the most important storage device of computer.

Second, different characteristics

1. Disk features:

(1) make use of the magnetic effect of electric current.

(2) the information carrier can also be rewritten repeatedly.

2. Characteristics of hard disk:

(1) the capacity of the hard disk is measured in megabytes (MB) or gigabytes (GB).

(2) the spindle motor of the hard disk drives the disk to rotate at a high speed, resulting in buoyancy to make the head float above the disk.

This is the end of the article on "what does computer disk mean?". I hope the above content can be of some help to you, so that you can learn more knowledge. if you think the article is good, please share it for more people to see.
