Computer networking is an integral component of most IT systems, making a strong understanding essential for software engineers and developers to craft more robust apps that can be shared over networks.
Introduction to Networking
Computer networks are all around us – from your local home network to the worldwide web. Knowing how these networks function and data flows between devices is an essential skill for professionals looking to advance in their careers or simply gain greater insight into technology in general.
As our world is becoming more dependent on technology, professionals with an in-depth knowledge of networking technologies are in greater demand. Possessing this skill set makes you a more sought-after candidate for positions like network administrator, systems administrator and IT support specialist.
Networking Technology
Computer networking technology encompasses any device or method for connecting computers together, whether this involves complex enterprise networks or simpler Wi-Fi systems that use client servers.
An undergraduate degree in computer networking equips you with the necessary skills to work with computer networks. A career in this area can be very fulfilling due to an increasing demand for infrastructure-level IT professionals.
Wired computer networks use cables or other forms of wired connections such as power or telephone lines to transmit data, and are typically found in homes or small offices. Wired networks utilize various transmission standards like Ethernet (which uses copper), Wireless Local Area Network (WLAN) which uses radio waves or ITU-T G.hn which uses existing home wiring as part of its high-speed LAN connectivity solution.
Wide-area networks (WANs) connect computers and smaller networks over larger geographic areas, such as multiple cities or continents. The largest WAN is the Internet, connecting billions of users worldwide. This is an essential component of doing business in the modern era.

A WAN can be set up through satellite, optical fibers or even regular unconditioned telephone lines with modem access – however more skills and expertise is necessary when managing large, complex WANs than with home or business networks due to increased security requirements and monitoring network activity.
Network Security
Network security specialists work to safeguard computer systems or groups of systems against cyber threats such as Trojans, spyware, worms and adware; viruses; hacker attacks or even simple spam.
These could infiltrate networks and slow their processes down, while viruses could corrupt files. This can significantly hinder an organization’s operations, even to the point of shutting them down completely. This is an area that Cisco networking training can be extremely beneficial in. Knowledge of network security can help defend your company.
The Department of Homeland Security defines network security as a collection of processes and technologies designed to prevent, detect and monitor unauthorized access to networks and their resources. This encompasses devices like switches and routers; application layer protection against cyber threats while it moves among applications; and transport presentation layers which protect integrity as it passes from device to device.
Network security also involves those responsible for managing these systems. A network security official creates strategies and policies for everyone on their network to follow, which helps ensure each person understands how they should apply protections against cyber threats.
Other tools and methods used by network security professionals may include firewalls, anti-virus and antimalware software; two-factor authentication (2FA), which combines something the user owns (like their password or mobile phone) along with something they know ( like their name); data loss prevention (DLP), which monitors email for signs sensitive data could leakage has taken place.

Networking Troubleshooting
Network troubleshooting is essential, whether for home networks or large corporate systems. Following a proven set of steps is more efficient than trying different things until one works than simply trial-and-erroring until something works.
Start by gathering information about the problem. This step entails identifying its symptoms and their effect on network users as well as interviewing those experiencing issues to better pinpoint its source such as faulty cables or software updates which don’t function correctly.

Once you have all of the information needed, it’s time to start testing theories. For instance, if you suspect a faulty router as the source of your issue, try swapping out other models until one works better; this may save time as opposed to waiting for manufacturers to provide replacement devices.
Network issues are infuriating, but left unaddressed can wreak havoc with businesses that depend on connectivity to operate successfully. That is why computer networking training courses that cover topics like OSI 7-layer model, IPv4 address management and cloud DNS can equip you with the skills to deal with troubleshooting when necessary.
Proper networking training can help your business handle technological changes and issues. This is why it is important to ensure your team is properly trained in these concerns.
