Can you tell me what you know about microprocessors?

"Microprocessors are powerful computer chips which contain the logic needed to control a device, process commands, and manage the functions of a complex piece of electronic equipment. Microprocessors designed by companies such as Cisco, Intel, and Motorola are standard pieces of equipment used in computers. This enables hardware manufacturers and software developers to create equipment and programs which interface with the microprocessor to perform specific functions. Other microprocessors designed by companies such as Qualcomm perform specific but limited functions across a wide range of equipment. An example of this would be a microprocessor modem within a cell phone that allows the device to communicate with the cellular network. Knowing the availability of microprocessors and the functions they perform enables me to simplify my designs and incorporate much of the functionality of the equipment into a single or multiple microprocessors."
