access time is said to be replaced by the average seek time. 5, burst data transmission rate (Burst data Transfer Rate) Refers to the computer through the data bus from the internal buffer of the hard disk read the highest rate of data, also known as the external data transmission rate (External data Transfer Rate). This parameter should theoretically be equal to the speed of the interface, such as UDMA/66 hard disk should be 66mb/s,

the CD drive read disk, what kind of disc can not read, but can be started with the CD-ROM. 5. Whether the drive is properly installed If the driver for the optical drive does not have its own driver installed, the CD-ROM drive loss will also occur. This occurs in general to improve the performance of the optical drive by artificially adding an optical drive accelerator or other program found from the network or CD. Typically, the drive is brought in both WIN98 and 95, and no additional addit

"Software and hardware is incompatible" three-dimensional software and some special software, may be in some microcomputers can not start or even install, which may have hardware and software compatibility problems. "Memory stripe Failure" is mainly due to loose memory, virtual welding or the quality of the memory chip itself. should be in accordance with the circumstances of the memory strip contac

situation is generally the addition of the so-called "optimization", "accelerator" or other procedures. You can enter the security form to remove the "CDROM" option in Device Manager, and then restart your computer to allow the system to discover new hardware to reinstall the drive. 6, CMOS set improper If the transmission form is incorrectly set in the CMOS settings-the Lao drive that does not support Pio MODE3 or Pio MODE4 or DMA/33 will appear in Windows without an optical drive icon and n

As usual, we'll look at the effect chart. What do you think? The effect is very good, let's look at the implementation of the process and code examples. Implementation principle As can be seen from the diagram, the explosion point is taken by the color value of a coordinate, and then based on some animation effects to complete. Take color value How to take the view color value of a certain point? Google, you can find a lot of answers. Don't say it specifically. Create a 1*1 bitmap, then r
