http://en.wikipedia..../Protocol_stack: this refers to the "network stack"; this is the area of your computer that deals with the sending and receiving of transmission data (via Internet); the "protocols" based in your machine via software (in the case of sending, say, an e-mail) initializes, prepares, packages, and sends it on its way to a destination, another computer, where that computer does just the opposite (receives, unpackages, does a
CRC, prepares it the data to view, presents it to you on your screen ((this is very intersting: your computer converts your e-mail to electrical signals, pure energy, and sends it on its way over the telephone or cable lines to its destinations))
