In Computers, What Is a Pointing Device?

A computer has a complete system for completing various tasks. This system consists of two parts, a hardware system and a software system. Both are indispensable. ^[1] Computer equipment is all kinds of machinery used to assist the normal operation of computers.

After a new board is inserted into a computer, a program cannot run, or a part of the computer cannot work, or even the entire computer cannot work. In fact, this kind of problem is not a problem with the new card, but a device conflict between it and other computer equipment.

For a computer device to work properly, it must be able to communicate with the host. However, after the card is installed in the computer, it often conflicts with the existing computer, and cannot work normally. The most common and prone resource conflicts are IRQ, DMA, and I / 0 conflicts. ^[2]
