Most of the time you download the installation software (for example, install JDK), you also need to know your computer's system type is 32-bit, or 64-bit. Different operating systems, the settings will vary. So how simple and convenient to see the computer is how many bits of the operating

interlinked, but the method of implementation is different. Common tips: Reboot the system to solve the problem Occasionally the Apple computer system will suddenly appear strange problems, such as the boot without any sound, the mouse to lose the response and so on. You can then apply the "most common" fix for Windows systems--Restart your

Those who say that Windows 7 is not good can either be useless or the computer configuration is too low to run slowly. As long as win7 is a dual-core CPU (64-bit best), 2 GB memory or above, supports 9.0c, m or above graphics card, the computer can run smoothly. For example, if the

, refers to the multi-channel program environment, one or two programs in multiple programs are used to simulate the function of the Peripheral Controller in offline input and output to achieve the "offline" input and output. Composition of the spooling System (1) Input well and output well: these are two large storage spaces opened up on the disk. (2) input buffer and output buffer: these are two buffers opened in the memory. (3) input process SP1 a
