Chapter 1. Review of TCP/IP Protocol Suite
and Python Language
This book assumes that you have the basic understandings of networking
protocols and the Python language. In my experience, a typical system,
network engineer, or developer might not remember the exact TCP state
machine on a daily basis (I know I don't), but he/she would be familiar with
the basics of the OSI model, the TCP and UDP operations, IP headers, and
more such.
This chapter will do a very quick revision on the relevant networking topics.
In the same view, we will also do a high-level review on the Python
language, just enough so that readers who do not code in Python on a daily
basis can have a ground to walk on for the rest of the book.Â
Specifically, we will cover the following topics:
The internet overview
The OSI and client-server Model
TCP, UDP, IP protocol Suites
Python syntax, types, operators, and loops
Extending Python with functions, classes, and packages
Worry not if you feel you need further information, as by no means do I think
the information presented in this chapter is exhaustive. Do check out the
reference section for this chapter to read more on your topic of interest.Â
