A peripheral is nothing but a device connected to a host computer, but actually not part of it and generally depends on the host. It can extend its host's capabilities, but does not form part of the core computer architecture. Computer peripherals are add-on hardware to the computer to improve its abilities such as printers, scanners and many more. But sometimes it’s observed that many peripherals are not compatible with the mainframe computer and the easiest way to solve this problem is we need to figure out where it started and from where we can start from there. In this way we can cut short the problem and can re-check the connections. Which makes a difference is checking the wires and screws and each time we install a new add-on card which supposed to be plug-and-play but it is not and it may as we made a mistake in the installation process. Then we have to go through the whole process again and then we can try once more. If still nothing is solved then maybe there might be a compatibility problem.

Every piece of hardware in our PC needs a driver to communicate and function with the operating system, the software applications, and other hardware components in our computer. Software drivers basically translate messages from and to the hardware in question and the operating system, allowing your computer system to work as a whole. Usually, any computer system is actually made up of a bunch of specialized pieces that do not communicate the low level language of other peripherals and for that it needs a great deal of translation to be able to talk and work effectively with them. These facts may not solve all the hardware problems we have but will help us a lot. But when trying to do any troubleshooting job, is that computers really are just logical devices and there is always a logical reason behind why things just not supposed to react the way they are. Finding what is that reason and then putting the right solution is not always easy but to do that ourselves we need to follow each step carefully.
