^ that.

i would also highly recommend you read a book on PIC microcontrollers to properly know how to use them.
try "PIC Microcontroller and Embedded Systems" by Mazidi and Makinly , its got good stuff on how to program in both Assembly and C language. choose whatever you are easy with.

No, not every PIC processor has one.
Check the data sheet on the PIC you wish to use, if it has a USART it will be described in the data sheet.

another question please
in data sheet i found in digital communication words that i can not understand

0 -A/E/USART

Yes, I do.

Look in the other Microchip literature, such as the data sheets, App Notes and reference manuals.
or one of the many micro-controller books (like the one Fr0stAngel suggested)
or google each term
or go to Wikipedia for these terms.
Just like joe61 showed you how to do (check his post again).
