Computer networks are at the heart of any modern infrastructure. Whether it'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.
The training “Everything you need to know about computer networks” has been designed to offer a comprehensive, structured and practical understanding of key networking concepts, from the basics to advanced configuration of Cisco equipment.
Understanding the basics of computer networks
This training begins with the essential foundations:
- The general operation of a computer network
- The concept of bandwidth and data rate
- Types of cables and their uses
- The role of a switch
- The role of a router
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).
Mastering the OSI model and network layers
The model OSI This course provides the essential theoretical foundation for understanding networks. It guides you through:
- The physical layer
- The bonding layer
- The network layer
- The transport layer
- The application layer
You will learn to precisely identify the role of each layer and understand their interactions in data processing.
IPv4, IPv6 and IP address calculation
A network cannot function without IP addressing. You will develop practical skills to:
- Understanding the different types of IP addresses
- Calculate the network address and the broadcast address
- Mastering subnet masks
- Configuring and understanding IPv6 addresses
- Identify the differences between IPv4 and IPv6
These skills are essential for any professional network setup.
Essential network protocols
Protocols are the language of networks. This training will allow you to understand them in depth:
- The difference between TCP and UDP
- How the protocol works ARP
- The services DNS, DHCP, FTP and SMB
- Messaging protocols: SMTP, IMAP and POP
- The operating principles ofHTTP
Thanks to clear explanations and practical demonstrations, you will finally understand what really happens behind every network connection.
Practical configuration with Cisco Packet Tracer
Theory alone is not enough. This training emphasizes practical application through:
- Step-by-step demonstrations
- Guided practical exercises
- Virtual network topologies
- Realistic scenarios
You will learn how to configure:
- Cisco switches
- VLANs
- Routers
- The routing protocol OSPF
You will even be able to influence the election of the DR (Designated Router) and the BDR (Backup Designated Router) in an OSPF environment.
Routing and VLANs: Taking it to the next level
The training allows you to understand in detail:
- How routing works
- The OSPF protocol
- Network segmentation with VLANs
- Inter-VLAN communication
These concepts are essential for building professional and secure network infrastructures.
