Introduction to Computer Networks and Internet Protocols

Importance of Networks: Computer networks are integral to daily life, akin to utilities like electricity and water. Disruptions in networks can have significant impacts. For a deeper understanding of how these networks operate, refer to our summary on Understanding the OSI Model and Computer Network Communication.
Course Objectives:
- Understand the backbone activities that enable the internet to function.
- Explore how computers communicate over networks, including the processes behind web page displays and email transmissions. This topic is closely related to Understanding Networking Protocols: IP, TCP, and UDP Explained.
- Learn about the basic functionalities of networks and how to write application programs.
- Discuss future trends in network-enabled applications and necessary designs.

Definition of Protocols: Rules that facilitate communication and functionality within networks.
Network Architecture: Understanding how two remote computers communicate and the protocols required for this interaction. For more on this, see Understanding Computers and Telecommunications in Information Technology.
Physical Layer: The foundational layer that ensures physical connectivity between systems, including wired and wireless connections.
Data Link Layer: Manages data transfer between devices and reduces collision domains to enhance bandwidth.
Network Layer: Responsible for routing data between different networks, utilizing routers and switches.

Path Establishment: Establishing a communication path between source and destination is crucial for effective data transfer.
Layered Approach: The course will follow a top-down approach, starting from application layers down to physical layers, examining various protocols at each level.

Recommended readings include "Computer Networks" by Kurose and Ross, and various online resources from the Internet Engineering Task Force (IETF).

The course will delve into the intricacies of networking technologies and prepare students for further research and practical applications in the field. For practical applications, consider checking out our guide on Mastering Packet Tracer: Step-by-Step Guide to Setting Up a Network.
