Design, implement, and manage network infrastructure
Network Engineering is the foundation of modern IT infrastructure, focusing on designing, implementing, and maintaining computer networks that enable communication and data transfer. As a network engineer, you will configure routers and switches, implement network security, troubleshoot connectivity issues, design network topologies, and ensure optimal network performance. This comprehensive roadmap covers networking fundamentals (OSI model, TCP/IP), routing protocols (OSPF, BGP, EIGRP), switching technologies (VLANs, STP), network security (firewalls, VPNs, IDS/IPS), wireless networking, and cloud networking. Network engineers are essential in all organizations, from small businesses to large enterprises and ISPs. The role requires strong problem-solving skills, understanding of protocols and standards, hands-on experience with networking equipment, and the ability to work under pressure during outages.
