Computer Networking

Computer Networking is the practice of connecting computers and digital devices to share data, resources, and services efficiently. It forms the backbone of modern communication systems, enabling organizations and individuals to exchange information securely and reliably across local and global environments.

Computer networking involves the design, configuration, and maintenance of both wired and wireless networks, including LAN (Local Area Network), WAN (Wide Area Network), and VPN (Virtual Private Network) infrastructures.

Key areas of focus include:
• Network design and architecture
• Router, switch, and firewall configuration
• IP addressing, subnetting, and routing protocols (TCP/IP, OSPF, BGP)
• Network security and performance optimization
• Troubleshooting and monitoring tools (Wireshark, Cisco Packet Tracer, etc.)

Strong networking knowledge is essential for IT professionals, system administrators as it supports the operation, scalability, and security of digital systems in both enterprise and cloud environments.
