This time the problem is big, we may need to study a guy Linux network implementation. Then to understand the communication between the operating system and peripherals, you may have job function email list to write a driver module in the middle to deepen the impression. Then look at digital job function email list circuits and try to figure out things like flip-flops and sequential circuits. Finally, the world is quiet and everything is enlightened. Wait a minute, how does a transistor act as a switch? Looks like we still have to study physics... In fact, I don't know what I said above, it's pure job function email list nonsense, hahaha. But what I know is that this "normal" thinking is definitely "abnormal". I'm just giving you a negative example, but I believe that many people will make this mistake of "breaking the casserole and asking to the end" when facing unfamiliar knowledge~ At the macroscopic level of understanding, the emphasis is job function email list on "doing not seek complete solutions", and only need to understand to the following extent. In the entire network, the most basic or core is the transmission of data. The entire network is built to serve job function email list data transmission. By analogy with the example of express logistics, we can initially understand what these seven layers are for. : 1. Application layer Then we have to study, how are these seven layers related? So, we have to continue to study the job function email list protocol, knowing that it is probably a layer-by-layer packet or unpacket to transmit data. But how does the protocol thing combine with the computer? For example, how does the operating system send IP packets to the network card.
