What are the devices that can input and output among the various devices of a microcomputer?
Among the various devices of a microcomputer, the device that can be both input and output is the disk drive.
The disk drive can both read the information stored on the disk into the memory and write the information in the memory to the disk. Therefore, it is considered both an input device and an output device.
The disk drive is a part of the disk memory in the electronic computer. It is used to drive the disk to rotate at a steady speed and control the magnetic head to record and read information on the magnetic layer of the disk according to a certain recording format and encoding method. It is divided into hard disk drives. , floppy disk drive and optical disk drive.
Extended information
The computer can store data through the hard drive. Although hard disk drive and hard disk are two different concepts, since the two are usually packaged together, both hard disk and hard disk drive usually refer to the device formed by combining the two.
The hard disks used in early desktop computers used IDE interfaces. IDE interface hard disks were cheap but low in cost performance. Nowadays, most personal computers use SATA interfaces or SCSI interfaces. The advantage of SCSI interface hard drives is that up to seven different devices can be connected to the same controller panel.
Since the hard disk rotates at a constant high speed of 3,000-15,000 rpm, it only takes a short time to read data from the hard disk.
If the solid state drive loses power, it may cause the current to disrupt the main control, causing the main control to shut down. Therefore, users who use solid-state drives, please do not cut off the power casually. Although solid-state drives are theoretically several orders of magnitude less likely to be damaged than mechanical hard drives, they still cannot withstand human failures.
