Whether it&#039;s for connecting computers, accessing the Internet, securing data, or enabling communication between servers, mastering network fundamentals is an essential skill for any IT professional.<\/p>\n<p>The training <strong>\u201cEverything you need to know about computer networks\u201d<\/strong> has been designed to offer a comprehensive, structured and practical understanding of key networking concepts, from the basics to advanced configuration of Cisco equipment.<\/p>\n<h3><strong>Understanding the basics of computer networks<\/strong><\/h3>\n<p>This training begins with the essential foundations:<\/p>\n<ul>\n<li>The general operation of a computer network<\/li>\n<li>The concept of bandwidth and data rate<\/li>\n<li>Types of cables and their uses<\/li>\n<li>The role of a switch<\/li>\n<li>The role of a router<\/li>\n<\/ul>\n<p>You will learn to understand how equipment communicates with each other and how data flows from one point to another in a local area network (LAN) or wide area network (WAN).<\/p>\n<h3><strong>Mastering the OSI model and network layers<\/strong><\/h3>\n<p>The model <strong>OSI<\/strong> This course provides the essential theoretical foundation for understanding networks. It guides you through:<\/p>\n<ul>\n<li>The physical layer<\/li>\n<li>The bonding layer<\/li>\n<li>The network layer<\/li>\n<li>The transport layer<\/li>\n<li>The application layer<\/li>\n<\/ul>\n<p>You will learn to precisely identify the role of each layer and understand their interactions in data processing.<\/p>\n<h3><strong>IPv4, IPv6 and IP address calculation<\/strong><\/h3>\n<p>A network cannot function without IP addressing. You will develop practical skills to:<\/p>\n<ul>\n<li>Understanding the different types of IP addresses<\/li>\n<li>Calculate the network address and the broadcast address<\/li>\n<li>Mastering subnet masks<\/li>\n<li>Configuring and understanding IPv6 addresses<\/li>\n<li>Identify the differences between IPv4 and IPv6<\/li>\n<\/ul>\n<p>These skills are essential for any professional network setup.<\/p>\n<h3><strong>Essential network protocols<\/strong><\/h3>\n<p>Protocols are the language of networks. This training will allow you to understand them in depth:<\/p>\n<ul>\n<li>The difference between <strong>TCP and UDP<\/strong><\/li>\n<li>How the protocol works <strong>ARP<\/strong><\/li>\n<li>The services <strong>DNS, DHCP, FTP and SMB<\/strong><\/li>\n<li>Messaging protocols: <strong>SMTP, IMAP and POP<\/strong><\/li>\n<li>The operating principles of<strong>HTTP<\/strong><\/li>\n<\/ul>\n<p>Thanks to clear explanations and practical demonstrations, you will finally understand what really happens behind every network connection.<\/p>\n<h3><strong>Practical configuration with Cisco Packet Tracer<\/strong><\/h3>\n<p>Theory alone is not enough. This training emphasizes practical application through:<\/p>\n<ul>\n<li>Step-by-step demonstrations<\/li>\n<li>Guided practical exercises<\/li>\n<li>Virtual network topologies<\/li>\n<li>Realistic scenarios<\/li>\n<\/ul>\n<p>You will learn how to configure:<\/p>\n<ul>\n<li>Cisco switches<\/li>\n<li>VLANs<\/li>\n<li>Routers<\/li>\n<li>The routing protocol <strong>OSPF<\/strong><\/li>\n<\/ul>\n<p>You will even be able to influence the election of the DR (Designated Router) and the BDR (Backup Designated Router) in an OSPF environment.<\/p>\n<h3><strong>Routing and VLANs: Taking it to the next level<\/strong><\/h3>\n<p>The training allows you to understand in detail:<\/p>\n<ul>\n<li>How routing works<\/li>\n<li>The OSPF protocol<\/li>\n<li>Network segmentation with VLANs<\/li>\n<li>Inter-VLAN communication<\/li>\n<\/ul>\n<p>These concepts are essential for building professional and secure network infrastructures.<\/p>\n<h3><strong>A comprehensive and structured training program<\/strong><\/h3>\n<p>The program includes:<\/p>\n<ul>\n<li>12 progressive sections<\/li>\n<li>106 detailed lessons<\/li>\n<li>Nearly 7 hours of rich content<\/li>\n<li>Regular multiple-choice quizzes to validate your knowledge<\/li>\n<li>Solved practical exercises<\/li>\n<li>Effective preparation for Cisco certification<\/li>\n<\/ul>\n<p>The content is derived from a program taught in person at several recognized computer science schools, guaranteeing a proven and clear pedagogy.<\/p>\n<h3><strong>Who is this training for?<\/strong><\/h3>\n<p>This training is ideal for:<\/p>\n<ul>\n<li>Beginners wishing to understand networks<\/li>\n<li>Computer science students<\/li>\n<li>IT technicians<\/li>\n<li>Beginner network administrators<\/li>\n<li>People preparing for Cisco certification<\/li>\n<li>Professionals wishing to consolidate their foundations<\/li>\n<\/ul>\n<p>No advanced technical prerequisites are required. All concepts are introduced gradually.<\/p>\n<h3><strong>Going further: CCNA certification<\/strong><\/h3>\n<p>If you wish to further your preparation for Cisco certification, also check out:<\/p>\n<p><strong>&quot;CCNA \u2013 Computer Network Fundamentals&quot;<\/strong><br \/>\n<a href=\"https:\/\/www.trucnet.com\/en\/ccna-fundamentals-of-computer-networks\/\" target=\"_blank\" rel=\"noopener\">https:\/\/www.trucnet.com\/ccna-les-fondamentaux-de-reseaux-informatiques\/<\/a><\/p>\n<p>This additional training will allow you to go even further in mastering the network concepts required for CCNA certification.<\/p>\n<h3><strong>Conclusion<\/strong><\/h3>\n<p>\u201cEverything You Need to Know About Computer Networks\u201d is a comprehensive, practical, and structured training course to master the fundamentals of networking.
