Ok..Ok,I am not familiar with Arduino board.I assumed that "computer" in this case is different from Arduino & was used as a source to upload some kind of program to the board after which computer hdd was formatted.
Computer means PC normal one.. window OS
You can connect Arduino Nano to PC, create program/sketch through Arduino IDE, compile it, upload it to Arduino Nano through USB connection, after uploading no need for computer to run the program.
Okay.
