Course Description

Embark on an enlightening journey into the world of computer networking with the comprehensive course "Computer Networking." This course, meticulously crafted for enthusiasts and professionals alike, belongs to the Information Technology category, specifically focusing on Web Servers and Cloud Computing.

In just over 4 hours of immersive content, this course provides a profound understanding of computer networks. You'll start by exploring the fundamentals, delving into what a computer network is and the various types of networks such as MANs (Metropolitan Area Networks) and WANs (Wide Area Networks). You'll learn about the intricate parts that make up a network and gain insights into how the Internet functions.

The course unravels the essential components of networking, highlighting the roles and functionalities of servers, clients, and hosts. The importance and function of a Network Interface Card (NIC) are discussed, along with a comprehensive understanding of protocols, which are crucial for network communication.

Dive into the world of network topologies, exploring the bus, ring, star, and mesh configurations. You'll gain knowledge about the OSI Model, offering you a layered perspective on how different networking processes interconnect, ensuring seamless data transfer.

Key networking devices such as modems, routers, switches, and repeaters (extenders) are examined, giving you a practical understanding of their roles in network management and optimization. You'll also explore how binary code operates, a fundamental element in computing and networking.

IP Addressing forms a crucial part of this curriculum. You'll learn about IP addresses, the challenges associated with IP addressing, and the basics of subnetting. You’ll also grasp how to establish and manage network IP addresses effectively.

This course ventures into the realm of cloud computing, starting from creating a cloud server to connecting with PuTTY, creating SSH keys, changing the default SSH port, and setting up a robust firewall. Furthermore, you'll acquire practical skills in installing and securing popular web technologies like Apache, MySQL, PHP, and PhpMyAdmin.

Advanced networking skills are also covered, such as using FileZilla with SFTP for secure file transfers, understanding Dynamic Host Configuration Protocol (DHCP), Domain Name System (DNS), routing tables, and configuring firewall rules with iptables.

Though new with no reviews yet, the "Computer Networking" course promises a well-rounded and in-depth educational experience, empowering you with the skills needed to excel in the ever-evolving field of computer networking.
