This article mainly explains "what can be used as both an input device and an output device in a computer". The content of the explanation in the article is simple and clear, and it is easy to learn and understand. let's study and learn "what can be used as an input device and an output device in a computer?"

The "disk drive" in the computer can be used as both an input device and an output device. The disk drive can be read or written through the disk, which can not only read the information stored on the disk into memory, but also write the information in memory to the disk.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

The "disk drive" in the computer can be used as both an input device and an output device.

Disk drive (Disk Driver), also known as "disk drive", is a storage device in which the disk is used as the recording information medium. The disk drive reads the data from the disk and passes it to the processor.

The disk drive can not only read the information stored on the disk into memory, but also write the information in memory to the disk, that is, it can be read or written through the disk. Therefore, it is considered to be both an input device and an output device.

The disk drive is a part of the disk memory in the electronic computer, which is used to drive the disk to rotate at a steady speed, and to control the head to record and read information according to a certain recording format and coding mode on the disk surface magnetic layer. it can be divided into three types: hard disk drive, floppy disk drive and optical disc drive.

Hard disk drive (Hard-Disk Drive) is a major computer storage medium, which consists of one or more aluminum or glass discs. These discs are covered with ferromagnetic material. The vast majority of hard drives are fixed and permanently sealed in the hard drive. Nowadays, removable hard drives are becoming more and more popular and there are more and more kinds.

Floppy disk drives (floppy disk driver), commonly known as floppy drives, are devices that read 3.5in or 5.25in floppy disks. Floppy drives are gradually becoming obsolete because of their small storage capacity.

CD-ROM drive is what we usually call CD-ROM drive, which is a device for reading CD-ROM information. Because the optical disc has large storage capacity, cheap price and long storage time, it is suitable to save a large amount of data, such as sound, image, animation, video information, movies and other multimedia information, so the optical drive is an indispensable hardware configuration for multimedia computers.

Thank you for your reading. the above is the content of "what can be used as both an input device and an output device in a computer?" after the study of this article, I believe you have a deeper understanding of what can be used as both an input device and an output device in the computer, and the specific use needs to be verified in practice.
