Summary  
This chapter covers the fundamentals of network programming, including how devices connect and communicate over different network types (LAN, WAN) using protocols like TCP/IP, HTTP, and FTP, as well as the roles of routers, switches, and other hardware in enabling data exchange.

General domain of usage  
Web and distributed system communication


Networking refers to the process of connecting multiple devices, such as computers, smartphones, and servers, to share data and resources. This process is essential in modern communication and supports everything from emails to smart home systems. In the past, devices operated in isolation, but today, networks create an interconnected web that enables seamless data sharing across the globe.


Explore the essentials of network security and understand how modern systems are protected from cyber threats. Learn about common network attacks, firewalls, intrusion detection systems (IDS), encryption, VPNs, and the key principles of securing wireless networks.
