PIC18F2550 is a High-Performance, Enhanced flash, USB Microcontroller with NANO-Watt-Technology. PIC18F2550 microcontroller is an 8-bit microcontroller designed by MICROCHIP. It is one of the cheapest microcontrollers of the PIC18FXXXX series. It is popular due to its performance, cheapness, and multiple features.
Because a controller has so many features, the manufacturer cannot offer I/O pins for all of them. Many of the controller's pins have numerous functions. By default, these functionalities are turned off; however, they can be turned on through programming. Each pin's function will be briefly described below.

PIC18F2455, PIC18F4455, PIC18F4550
It is used with those devices which required an interface with a PC.
Most of the smart application uses PIC18F2550 because it fills almost all the communication protocol of most of the applications.
The PIC18F2550 is used in the same way as any other microcontroller, Microcontrollers are not like digital ICs, which require only the connection of electricity to function. Before getting the chip to work, the microcontroller has to be programmed. To get the PIC18F2550 to work, we must first save the correct software file to the controller's FLASH memory. Once the controller receives power, it runs the code stored in FLASH memory to generate the answer.
List the functions to be executed by PIC18F2550
Write these functions in ‘IDE software’ using a supported programming language
(MPLAB IDE for Windows OS [www.microchip.com/mplabx-ide-windows-installer ] )
(For these MPLAB IDE you can use ‘C’ language to write the application program)
After writing the desired program compile for error elimination using IDE.
After successful compilation IDE application generates a HEX file for the written program.
Choose the programming device (usually ‘PIC kit 3’) which establishes communication between PC and PIC18F2550.
Run the HEX file dumping software which is related to the chosen programming device.
Choose the appropriate program HEX file.
Burn the HEX file (generated for the written program) in PIC18F2550 flash memory using this program.
Disconnect the programmer and connect the appropriate peripherals for the controller.
