    I am new in this field and interested in knowing is it possible to interface two PIC together?
    if it is possible, how?

    Of course it is. It is the same as interfacing any other circuit elements together. What are you trying to achieve? this may help us help you

    Sure... How depends on your needs, serial is probably the most popular , parallel works if you have the pins, and even simple 1 for 1 pin digital logic is used if you only need basic communication... I find myself using binary pin for pin logic a lot of time as it's easy and works well if the data is simple stuff...

    i want to know how to interface PIC16f877a with another pic18f4550. the 18f4550 will be use for ps2 controller while pic16f877a will be connected to output. the purpose for learning and for fun actually.

    What kind of information are you trying to send from one to the other? That is the key. If you just need to signal a single on / off state, then you would just connect and output of one to an input of the other. So tell us what exactly what you want to communicate from one PIC to the other.
