It took me a whole night to finish chapter 1. Reading English text book is such a torture, yet i know i've got to hang in there. Since escaping from it won't change anything. You've got to do what you've got to do.
The following are some notes.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------
Ping and Traceroute both use ICMP
Broadcasting: sending a UDP datagram to every host on a specified network. it is different from multicasting.
There are three types of IP addresses: unicast(destined for a single host), broadcast(destined for all hosts on a given network), and multicast(destined for a set of hosts that belong to a multicast group).
Any application can call a standardlibrary function to look up the IP address( or addresses) corresponding to a given hostname. Similarly a function is provided to do the reverse lookup -- given an IP address, look up the corresponding hostname.
TCP segment. IP datagram. frame.
A physical property of an Ethernet frame is that the size of its data must between 46 and 1500 bytes.
Always remember, I read to gain some knowledge, not for the purpose of finishing reading a book. So, don't be afraid of being "too slow". Take notes!!!
