1. Introduction


Understanding the fundamentals of computer networks is crucial before diving into Windows Server 2025. Networks act like bustling cities of interconnected roads where hosts communicate with each other. This chapter builds the foundation for mastering server management in today’s IT landscape.


2. Hosts, Nodes, and Client/Server Architecture


A host is any device connected to the network, while nodes represent points of communication. The client-server architecture enables clients to request services and servers to provide them, forming the backbone of modern networking.


3. IP Addressing and Subnetting


IP addresses function like postal codes in the digital world, uniquely identifying devices. Subnetting divides networks into smaller segments for efficient communication and resource management.


// Example of IPv4 address
192.168.1.1

// Example of subnet mask
255.255.255.0

4. Network Operating System (NOS)


The NOS acts as the conductor of the network orchestra, managing communication between devices. It requires specific hardware and software configurations to run efficiently.


5. Windows Server 2025 Overview


Windows Server 2025 introduces enhanced security protocols, hybrid cloud integration, and improved technical support. Compared to Windows Server 2022, it offers better scalability and performance.


Editions:

  • Standard Edition
  • Datacenter Edition
  • Azure-Integrated Edition

6. System Requirements


  • Minimum RAM: 8 GB
  • Operating System: Windows 11 Pro
  • Disk Space: 500 MB available
  • Internet Connection: Active

7. Installation Media


To install Windows Server 2025, download the ISO file and prepare bootable media. This step ensures a smooth installation process.


// Example command to create bootable USB (Linux)
sudo dd if=WindowsServer2025.iso of=/dev/sdX bs=4M status=progress

8. Windows Admin Center


Windows Admin Center is the companion tool for managing servers. It provides a web-based interface for configuration, monitoring, and troubleshooting.


// Example installation command (PowerShell)
msiexec /i WindowsAdminCenter.msi /qn /L*v log.txt

9. Conclusion


By mastering networking fundamentals and understanding Windows Server 2025, administrators gain the skills to manage modern IT infrastructures with confidence. This chapter equips you with both theoretical knowledge and practical tools for success.
