We would like to thank our family members for the support they have provided for us to focus on the book during our personal time.

Introduction of Client-Server Networking: An Overview, you will learn Modern network gear is capable of transmitting small messages known as packets, which are typically no more than a few thousand bytes in size. How can these little individual messages be merged to make conversations between a web browser and a server, or an e-mail client and your ISPs mail server?

in this section. It merely fixes the first of the two difficulties mentioned above. It assigns port numbers to packets destined for different services on a single system, as described in the next section. Nonetheless, when it comes to packet loss, duplication, and ordering, network programs employing UDP must fend for themselves.

you will learn, It uses the same rules as UDP to incorporate port numbers and provides ordered and reliable data streams that mask the fact that the continuous stream of data has been cut into packets and then reassembled at the other end from applications.

After understanding the fundamentals of UDP and TCP, the two major data transports accessible on IP networks, its time for me to take a step back and discuss two larger challenges that must be addressed regardless of whatever data transport you use. In this chapter, Ill talk about network addresses and the distributed service that converts names to raw IP addresses.

, whenever your software has to seek for a DNS hostname, UDP is almost certainly participating in the background.
