When the typical PC compatible computer is first turned on it runs through a series of self tests called the "Power On Self Test", or "POST" for short.

The original designers didn't know that there would always be a monitor or other kind of display device, so the standard was that the POST would sound a series ob "beeps" to identify the results of the POST.

A single, short "beep", generally means everything is okay.

note the link at the bottom of this page. It should guide you to a location that lists the POST "beep codes".

Which switch increases speed of processor?

There is no such physical switch on common modern cpus that increases the speed of cpu. To increase cpu speed one has to overclock it. Overclocking depends on the cpu and the motherboard. It is generally not preferable to overclock as it reduces the life of cpu and the motherboard, and can even lead to complete destruction of either or both of the components in worst case.

Is the CPU the same as a microprocessor?

No. While a CPU is an example of a microprocessor, many microprocessors are not CPUs, but perform other tasks to aid the CPU. An example would be the GPU of a video card, or the DSP (Digital signal processor) of a modem or sound card.
