Question A: What are the most important capabilities an organization should look for when selecting a network operating system, and how many different networking systems should concurrently be used?

Question B: What is the major difference between a hub and switch? Which one is more efficient at routing traffic, and which is preferable in larger network configurations?

Paper For Above instruction

The selection of an appropriate network operating system (NOS) remains a critical decision for organizations aiming to establish reliable, secure, and efficient networks. Several key capabilities should be prioritized during this selection process. First and foremost, compatibility with existing hardware and software ecosystems ensures seamless integration and minimizes operational disruptions. For instance, organizations utilizing Windows-based environments will benefit from Windows Server OS, whereas those seeking robust open-source solutions might prefer Linux distributions tailored for enterprise networks (Hussain, et al., 2017). Second, scalability is vital, particularly for organizations anticipating growth, as it allows the network to expand without significant overhauls. Security features also feature prominently; the NOS must provide advanced security protocols such as encryption, access controls, and intrusion detection systems to safeguard sensitive data (Zhou & Dopico, 2019). Additionally, ease of management and support capabilities—like centralized administration, troubleshooting tools, and vendor support—are essential for maintaining network health (Yadav & Kumar, 2020).

Regarding the number of networking systems that should be used concurrently, organizations often operate multiple systems to balance redundancy, security, and specialized functions. For example, a primary NOS might manage core functions, while auxiliary systems support specific functions such as cloud integration or virtualization (Li & Wang, 2021). The decision hinges on organizational needs: smaller entities may rely on a single system, while larger corporations might deploy multiple interworking systems to optimize performance, security, and fault tolerance. While multiple systems can provide resilience, they also introduce complexity in management and compatibility challenges. Thus, a carefully designed architecture that minimizes the number of disparate systems while meeting operational requirements is ideal."

Major Difference Between a Hub and Switch & Their Efficiency in Routing Traffic

Hubs and switches are fundamental devices used for network connectivity, but they differ significantly in how they handle traffic. A hub functions as a simple multiport repeater that broadcasts incoming data packets to all connected devices, regardless of the intended recipient. Consequently, this broadcasting approach leads to unnecessary network traffic and potential security vulnerabilities, as data can be intercepted by any device on the network segment (Odom, 2018).

In contrast, switches actively manage traffic by examining the MAC addresses of incoming frames and directing data only to the specific port associated with the destination device. This targeted filtering enhances network efficiency, reduces unnecessary traffic, and decreases collision domains (Tanenbaum & Wetherall, 2011). Furthermore, switches support full-duplex communication, allowing simultaneous data transmission and reception, significantly boosting bandwidth utilization.

In larger network configurations, switches are more suitable than hubs because they efficiently segment the network, limit broadcast traffic, and mitigate issues such as broadcast storms. Implementing switches fosters scalable and manageable networks, preserving performance as the network expands. Hubs, while cheaper, are generally considered obsolete in modern networks due to their inefficiency and security concerns (Stallings, 2013). Therefore, switches are preferable for large, complex networks owing to their superior traffic management and scalability.
