This article explores the different types of computer networks—PAN, LAN, MAN, and WAN—based on coverage and purpose. It explains how clients, servers, hosts, and nodes function within networks, and highlights the roles of switches and routers in communication. By the end, readers will understand both the classifications of networks and the essential components that make them operate effectively.
This article examines computer network architectures, including Peer-to-Peer (P2P) and client/server models. It then explains IP addressing, subnetting, IPv4, and IPv6. The discussion continues with server hardware and software essentials, highlighting components such as CPU, RAM, disks, and network interfaces. These fundamentals form the basis for managing Windows Server 2025, helping administrators design and operate secure, scalable, and efficient networks.
A Network Operating System (NOS) is specialized software designed to manage and provide services in a network environment. It enables centralized control of resources, authentication, access management, and client-server interactions. Prominent examples include Windows Server, Linux Server, and macOS Server, each delivering comprehensive network services.
