Computer Networking
Computer networking is the practice of connecting computing devices together to share resources, exchange data, and communicate over digital networks. It involves the design, implementation, management, and security of network infrastructure using protocols, hardware, and software. This foundational concept enables technologies like the internet, cloud computing, and distributed systems.
Developers should learn computer networking to build applications that communicate over networks, troubleshoot connectivity issues, and design scalable systems. It's essential for web development, cloud services, IoT, and cybersecurity, as understanding protocols like TCP/IP, HTTP, and DNS helps optimize performance and ensure reliability in distributed environments.
