microcontroller is a computer on a chip (IC) which contains processor which is programmed mainly by C language and used to control systems such as elevator, cars.... and so on.
PIC is a type of microcontroller products from micochip company.

The PIC is a specific architecture of microcontroller.
PIC Microcontroller which means Peripheral Interface Controller. PIC Microcontroller is originally developed by General Instrument's Microelectronics Division.
The difference is base on the requirement of their0 application.

No, pic16f877A is powered by a 8 bits pic core. the 877A is an upgrade for the 877 version. same for the sister microcontroller pic16f876A and pic16f876. I ve been fan of this microcontroller for years. It is powerful and you can do a lot of thing with it. You can you can have it from www tmartis com together with many other stuff that you can purchase together. I always do my purchases from there. Have fun
8051 is an old microcontroller design. It has been updated and expanded into a family of microcontrollers manufactured by several companies. PIC is not a microcontroller, but is an extensive family of microcontrollers designed and manufactured by Microchip, Inc. Both are quite popular, and there are many other microcontrollers available.
In PIC Microcontroller , During the Fatching of instruction no. 1it needs of one clock cycle, then after for the exicution of instruction no. 1 it reqires one extra clock cycle , but at the same time it fatches inst. no. 2 . Similarly, during the execution time of inst. no. 2 , it fatches inst. no. 3 and so on.In other words we can say that, PIC Microcontroller requires 2 clock cycle at starting the after it requires only one clock pulse. In this way we can say that instruction pipelining is done in PIC microcontroller.
PIC's are programmable microcontroller chips made by Microchip Inc. PIC's can be programmed to do timing functions, but they can do many other things as well. 555's are dedicated purpose timer chips made by several different manufacturers. They have no intelligence, they are strictly analog electronics.
Microcontroller = (microprocessor+memory+peripherals) on a single chip
