- Common network operating systems like Windows Server, Linux-based solutions, and Cisco IOS offer features for managing resources, security, and scalability across enterprise networks.
- Each network operating system, from VMware ESXi to macOS Server, is tailored to different environments, providing specific benefits depending on business needs.
Network operating systems (NOS) play a crucial role in managing, securing, and optimizing resources across interconnected devices in a network. Unlike traditional operating systems, which manage resources on a single device, NOS are designed to coordinate and control resources in larger, distributed environments. As networks grow in complexity, choosing the right NOS becomes essential for ensuring efficiency, security, and scalability. Let’s take a look at some of the most common network operating systems in use today.

Microsoft Windows Server
Microsoft Windows Server is one of the most widely used network operating systems for businesses of all sizes. Known for its user-friendly interface and powerful features, it supports a range of services like file and print sharing, Active Directory for user management, and Hyper-V for virtualization. Windows Server is often the go-to choice for enterprise networks, offering seamless integration with other Microsoft products.

Linux-Based Network Operating Systems (Ubuntu Server, CentOS, Red Hat Enterprise Linux)
Linux-based network operating systems are popular for their flexibility, security, and cost-effectiveness. Ubuntu Server, CentOS, and Red Hat Enterprise Linux (RHEL) are common choices for businesses and organizations that require a customizable, open-source solution. These operating systems are widely used in web hosting, cloud environments, and data centers.

Cisco IOS (Internetwork Operating System)
Cisco IOS is the operating system used in most Cisco networking hardware, such as routers and switches. It is designed to provide robust, enterprise-grade routing, switching, and security features for large-scale networks. Cisco IOS is a top choice for organizations that need a highly reliable and secure network infrastructure.
