SteveA microcontroller is a small and low-cost computer built for the purpose of dealing with specific tasks, such as displaying information in a microwave LEDor receiving information from a television's remote control. Microcontrollers are mainly used in products that require a degree of control to be exerted by the user.

A MCU is a electronic micro chip that can be programmed to control appliances in the outside world, it can control lights, motors and all kinds of electrical and electronic appliances like opening doors, controlling surveillance cameras, analog to digital conversion and many more. With one MCU, one can do the work of many other electronic components and logic chips, The 8-bit PIC® microcontroller solutions feature a powerful architecture, flexible memory technologies, comprehensive easy-to-use development tools, comprehensive application notes, complete technical documentation and post design-in support through a worldwide sales and distribution network. Microchip is committed to easy migration across product families, providing seamless program memory expansion, pin compatibility, and a unified development environment for all products

What is the basic unit of a capacitor?
micro farad
Is it advisable to use a separate micro-controller for servo motor controller of a robot rather than using only one micro-controller for the whole system and why?
Yes, most MCU's can not multi task it can run only one program at a time, so if you run a stepperor servo motor from one MCU it will slow down the whole program so, if you have send the command from the main MCU to the other one that is controlling the stepper or servo the main MCU can go on doing other things while the stepper MCU can take its time taking the stepper motor thru its paces If you have to run more than one stepper and using only one MCU, the MCU will have to drive the one stepper with one pulse and then the next stepper, you don't need a large MCU to drive a stepper only 4 bits is needed a 8 pin PIC like the PIC12F675 is all you need, GP0 to GP3 can drive the stepper while the chip can receive commands on GP5 that is a input pin only ,then you still have GP4 spare to drive a LED or a relay or you can use it as a DTR to send an interrupt to the main MCU and tell it that its done with the last command and ready for the next. A string of commands can be received by the 12F675 in serie on one pin and be stored in onboard EEPROM for use as needed

Why the cost of microprocessor is greater than that of a micro controller?
Microprocessors tend to be much faster than microcontrollers. As real time systems usually don't require fast processors the additional power used for the extra speed is seen as wasted. Older boards are also preferred as it is less likely to contain bugs.
Sinking and sourcing capability of microcontroller?
Sinking and sourcing current refers to current going into and out of the MCU (respectively)
