An optical disk drive is what we usually call a CD-ROM, a device that reads information from a disk. It is an indispensable hardware configuration for multimedia computers. The storage capacity of the optical disk is large, the price is low, and the storage time is long. It is suitable for storing a large amount of data, such as sound, images, animations, video information, movies, and other multimedia information. There are three kinds of ordinary optical disk drives, CD−ROM, CD−R, and CD−RW. CD−ROM is a read-only optical disk drive; CD−R can only be written once and cannot be rewritten later; CD−RW is repeatable and can be read. Optical drive. The DVD-ROM and its discs DVD-R, DVD-RW now appear again. However, the server is generally equipped with an ordinary CD-ROM.
The most basic measure of optical drive performance is the data transfer rate (Data Transfer Rate), which is often referred to as the double speed. The single speed (1X) optical drive means that the read rate of the optical drive per second is 150KB. Similarly, double speed (2X) This means that the read rate per second is 300KB. Currently, CD-ROM drives on the market are generally above 48X and 50X.
Air intake Pressure Sensor (ManifoldAbsolutePressureSensor), hereinafter referred to as a MAP.It with vacuum tube connecting the intake manifold, as the engine of different rotating speed and load induced changes in the intake manifold vacuum, again from the change of the internal resistance of the perceptron, converted into a voltage signal, for ECU modified fuel injection and ignition timing angles.
