Network Fundamentals: Start with the basics of networking, such as IP addresses, subnets, DNS, and DHCP.
TCP/IP Model: Study the five-layer TCP/IP model, which is the standard for Internet communication.
Network Devices: Get familiar with the common network devices, such as routers, switches, and firewalls, and their functions.
LANs and WANs: Understand the differences between Local Area Networks (LANs) and Wide Area Networks (WANs), and the various technologies used to connect them.
Network Security: Learn about the security threats that networks face, and the measures that can be taken to protect them, such as firewalls, encryption, and access controls.
Wireless Networking: Study wireless networking technologies, such as Wi-Fi, Bluetooth, and cellular networks.
Routing and Switching: Learn about the concepts and protocols used in routing and switching, such as OSPF, BGP, and VLANs.
Network Troubleshooting: Practice troubleshooting common networking issues, such as connectivity problems, slow performance, and security breaches.
This training covers the essential topics in computer networking, but there is much more to learn. Consider taking a certification, such as the CCNA (Cisco Certified Network Associate), for a deeper understanding of the subject.
