Networking Basics: What You Need to Know?

Even IoT devices are connected to computers, mobile phones, and peripherals via a network.

The Foundations of Networking: Switches, Routers, and Wireless Access Points.

Switches, routers, and wireless access points constitute the fundamental components of networking infrastructure. By means of these devices, the interconnected entities within your network are able to establish communication amongst themselves as well as with external networks, such as the Internet. Switches, routers, and wireless access points fulfill distinct roles within a network infrastructure..


Switches serve as the fundamental building blocks of the majority of corporate networks. A switch functions as a central device that facilitates the connection of computers, printers, and servers to a network within a physical infrastructure such as a building or a campus.

Switches facilitate communication between devices within a network, as well as enable connectivity with external networks, thereby establishing a network infrastructure for the purpose of resource sharing. By means of facilitating the exchange of information and effectively distributing resources, switches have the potential to provide cost savings and enhance productivity.

In the realm of networking fundamentals, individuals are presented with a choice between two fundamental categories of switches: on-premises switches and cloud-managed switches.

  • A controlled on-premises switch facilitates the configuration and monitoring of a local area network (LAN), hence providing more control over network traffic.
  • Do you have a limited-sized IT team? The utilization of a cloud-managed switch has the potential to streamline the process of network management. The user is provided with a straightforward user interface, the ability to manage several sites comprehensively, and automatic updates that are directly transmitted to the switch.


Routers facilitate the interconnection of numerous networks. In addition, they facilitate the connection of computers within those networks to the Internet. Routers facilitate the sharing of a solitary Internet connection among multiple networked computers, resulting in cost savings.

Networking Basics

A router functions as a dispatcher. The process involves the analysis of data transmission within a network, the selection of an optimal route for data traversal, and the subsequent forwarding of the data along the chosen path.

Routers serve the purpose of establishing connectivity between a business and external networks, safeguarding sensitive data from potential security breaches, and facilitating the allocation of network resources by determining the precedence of computer systems.

In addition to their fundamental networking capabilities, routers are equipped with supplementary functionalities aimed at facilitating or enhancing network operations and security. The selection of a router for security purposes may vary depending on specific security requirements. For instance, one may opt for a router equipped with a firewall, a virtual private network (VPN), or an Internet Protocol (IP) communications system.

Access Points

An access point* facilitates wireless connectivity for devices by eliminating the need for physical wires. A wireless network facilitates the seamless integration of new devices into existing infrastructure and offers adaptable assistance to individuals who operate remotely.

Networking Basics

An access point functions as a network amplifier.  The primary function of a router is to allocate and manage the available bandwidth inside a network.  In contrast, an access point serves to expand the reach of this allocated bandwidth, enabling the network to accommodate a larger number of devices and facilitating their connectivity from greater distances.

However, an access point performs other functions beyond the mere extension of Wi-Fi connectivity. Additionally, it has the capability to provide valuable information regarding the many devices present within the network, offer preemptive security measures, and fulfill a multitude of other pragmatic objectives.

*Access points are capable of supporting many IEEE standards. Every standard represents an amendment that has been formally ratified through a gradual process. The standards exhibit diverse frequency ranges, have distinct bandwidth capacities, and accommodate varied quantities of channels.

Wireless Networking

When establishing a wireless network, individuals have the option to select from three distinct deployment methods: centralized deployment, convergent deployment, and cloud-based deployment. Assistance is sought in determining the optimal deployment strategy for one’s firm. Do you need to engage in a conversation with a knowledgeable individual in the field?

  1. Centralized Deployment

Centralized deployments are the prevailing form of wireless network systems, typically implemented in settings such as campuses, where buildings and networks are situated in close proximity to one another. This deployment serves to centralize the wireless network, thereby streamlining the process of updates and enabling the implementation of sophisticated wireless capabilities. Controllers are often deployed on-premises and situated in a centralized place.

  1. Converged Deployment

Converged deployments provide a uniformity of wireless and wired connections, particularly advantageous for smaller campuses or branch offices. This deployment integrates wired and wireless connectivity on a single network device, specifically an access switch, which serves as both a switch and a wireless controller.

  1. Cloud-Based Deployment

The present system utilizes cloud technology to effectively oversee and control network devices that are placed on-premises across several geographical regions. The implementation necessitates the utilization of Cisco Meraki cloud-managed devices, which offer comprehensive network visibility via their dashboards.
