Server
A server is a computer or software system that provides resources, data, services, or programs to other computers, known as clients, over a network. It handles requests from clients and delivers responses, enabling functionalities like hosting websites, managing databases, or running applications. Servers can be physical hardware (e.g., rack-mounted machines) or virtual instances (e.g., cloud-based virtual machines).
Developers should learn about servers to deploy and manage applications, handle scalability, and ensure reliable service delivery in production environments. This is essential for web development, backend systems, and cloud computing, where servers host APIs, databases, and user-facing services. Understanding servers helps in optimizing performance, security, and resource allocation for real-world projects.
