Answers

  1. The initials 'PIC' are said to stand for "Programmable Interface Controller"

  2. EEPROM is special because it can retain it's contents even when the power is turned off, so if your program needs to keep any data while the device is turned off, it can use the EEPROM

  3. A file register is a numbered memory location that your program can use to store temporary values it's using while it is running.

  4. A PORT is how your program talks to the outside world. It is represented by two file registers, one, PORTx, contains the current state of the port, and the other, TRISx, tells the chip if each pin is an output or an input
