specific hard disk interface, Their speed difference is also greater. IdeThe IDE's English is all called "Integrated Drive Electronics", or "Electronic integrated Drive", which is meant to be the hard drive that integrates the hard disk controller and the disk body. The integration of the disk and the controller reduces the number and length of cables to the hard drive interface, enhances the reliability of the data transmission, and makes it easier to make the hard drive because the hard drive

practical applications, it is also customary to use the IDE to address the earliest IDE type hard disk ATA-1, a type of interface that has been eliminated with the development of interface technology and later branched out into more types of hard disk interfaces, such as ATA, Ultra ATA, Interfaces such as DMA, Ultra DMA, and so on are part of the IDE hard disk.

want the drive to vibrate during operation,The computer's vibrating magnetic arm can also vibrate, and the head may touch the track,And the disc has been spinning, it is possible to scrape the disc.We want the hard drive to maintain a stable working state.The hard disk is actually a mechanical device, only a minute to turn 10,000 rpm,While Pathfinding is a mechanical work, the main time to fetch data from a hard drive is spent on seeking the road.Read data consumption time from hard disk: Maxim

PATA is called parallel ATA hard drive, with a four-core power cord and a 80-core data line connected to the motherboard, which transmits data in parallel and in a column (string) transmission. Due to the restriction of parallel transmission, transmission rate is low, PATA hard drive is not needed. Introduction to the same port PATA standard specification was produced in the 80 's in the middle of the last century, Imprimis company launched t

the employee. The external port of the PBX is fxo and the internal port is FXS. Fxo, external exchange board. Its full name is foreign exchange office. It is a relay interface, which is generally connected to the port of the local machine or the extension of the upper-level switch. It provides an out-of-band route for the upper-level switch to implement the loop remote connection function. FXS is an extern

Block device drivers for flash memory devices The first version of Windows CE was used solely on platforms with battery-backed Ram storage with a simple file system to manage the storage. however, Windows CE versions 2.10 and later are often used on embedded systems that require persistent storage and cannot depend on battery-backed Ram storage. as a solution Windows CE can use flash memory, which is the industry standard for nonvolatile storage in embedded applications. The two leading

SATA is the abbreviation for Serial ATA, Serial ATA. This is a new type of hard disk interface that is completely different from parallel ATA, and is named because it transmits data in a serial way. SATA bus using embedded clock signal, with a stronger ability to error correction, compared with the past, the biggest difference is that the transmission instruction

capacity is smaller, so when you design the BIOS, when converting addressing addresses from address registers of INT 13 to an IDE (ATA) address register, only the 10-bit address in the INT13 corresponds to the 16-bit cylindrical registers in the IDE (ATA) interface, and the not-used 6-bit ( High register) address is set to 0. At the same time, only the 6-bit sector address corresponds to the 8-bit sector r
