Understanding network bits
Posted on 2011-09-16
Ive been trying to figure out how networks actually work.
I understand that the data is sent by packets, and that each packet is made up of bits of 0's and 1's (On and off of the electrical signal), but my question is if I wanted to read the the data stream - ie 1010111100110110011100001100110100001111100111001100111011011101, I understand that the first 96 bits contain the senders IP, Receiver's IP, Protocol and Packet numer, but If Im reading the first 96 bits of data, what bits are the senders IP, Receiver's IP etc????
Also how do you know when a BIT has started, and the next BIT starts, and what is the frequency of the reading?
I know this is all a bit technical, I just wanted to understand a bit better :-)
