Hello, everyone. The meeting will answer your questions. What does hdd network mean and what does it mean on hdd network? many people don't know it yet. Now let's take a look at it.

Answer:

1, Hdd network means the abbreviation of Hard Disk Drive, that is, the English name of hard drive, the most basic computer memory, computer hard disk (drive C and drive D are disk partitions) belong to hard drive; hard drive (alias hard disk, Winchester hard disk) is a kind of non-volatile memory based on hard disk rotating disk.

2. Definition of hard disk:

3. The hard disk is the most important storage device of the computer, which is composed of magnetic head, disk, motor, main control chip and so on. The reading and writing mode adopts semi-random access, and the data in the hard disk can be read in any order, but the speed of reading data is different in different locations. Hard disk capacity is measured in megabytes (MB) or gigabytes (GB), 1GB storage 1024MB GB; 1tbbytes 1024 GB; but hard disk manufacturers usually use 1G=1000MB when specifying the hard disk capacity, so the capacity we see in BIOS or formatting the hard disk will be less than the factory trademark value. In the early days, the hard drives used in desktop computers used IDE interface, and the hard drives with IDE interface were cheap, but the performance-to-price ratio was low. Most personal computers use the SATA or SCSI interface; the advantage of the SCSI hard drive interface is that up to seven different devices can be connected to the same controller panel; because the hard drive rotates at a constant speed of 3000-15000 revolutions per minute, it only takes a short time to read data from the hard drive.

This is the end of this article. I hope it will be helpful to all of you.
