认识linux中的设备名称(国外英文资料) Understanding device names in Linux Computer with CPU operation, memory to store programs and data, and some devices, such as disk drives, keyboard, display card, network card, modem card, sound card, serial port and parallel port, and so on. The power supply power bus on the motherboard of the equipment and CPU together, box them up. In the past, many devices were plug-in (printed wiring boards). Today, many devices, except the card, are already small enough to be on the main board. The card on the main page may contain more than one device The computer to work, each device must be in its driver (it is also a part of the operating system running on CPU) running under control. The driving program and the special file under the /dev directory together, although they are not real. They have files like hda1, ttyS0, eth1 and other such names. One, hard disk Each hard disk is represented as a separate device file. There are usually only 2-4 IDE hard drives. These are /dev/hda, /dev/hdb, /dev/hdc, and /dev/hdd. SCSI is /dev/sda, /dev/sdb, and so on. Two floppy drive The name of the floppy drive is complex, so Linux has a specific floppy device type that automatically detects floppy disk types in floppy drives. It uses different floppy disk types to try to read the first sector of the newly inserted floppy disk until the correct one is found. This naturally requires the floppy disk to have been formatted. The automatic equipment is called /dev/fd0, /dev/fd1 and so on. Three, SCSI device When a new SCSI master card is detected, the SCSI driver looks for the connected device. Please check the system log and your device is correctly detected. The new SCSI device will be specified as the first available SCSI device file. The first SCSI hard disk is /dev/sda, the first SCSI tape drive is /dev/st0, and the first CD-ROM will be /dev/scd0. Four, network card equipment Linuxs Ethernet card interface is often referred to as eth0, eth1, and so on. Ring cards ar
