Networking basics that You Need to Know

The computer network has evolved to unimaginable limits in the past two decades. Today networking technologies are faster and more affordable. The networks comprise of several elements including computers, routers, switches, and cables all interconnected to transfer signals and data. Understanding how networks work is an important step in building a wireless network in the local community. Switches, wireless access points, and routers are an essential part of networking basics. They have unique functions which act together to complete a connection. Here is what their individual roles are in a network.


Switches are the foundation of most of the networks. It is a controller which connects the computers with other devices like printers and servers which creates a local network. Switches allow different devices to communicate with each other and other networks. It can create a network of shared resources. With the help of information sharing and resource allocation, switches can help in increased productivity. There are two types of switches one can choose – on-premises and cloud-managed.

An on-premises switch can help you configure and monitor your LAN and provides better control over your traffic.

The cloud-managed switch can ease your network management with a simpler interface and multisite full stack management.


Routers help in connecting multiple networks together. They also connect computers with networks on the internet.  It can enable multiple computers to share a single internet connection, which saves money. The role of the router is to analyze the data that is being sent across a network. It defines the path of data flow. The router connects your business to the world while also protecting it from security threats. You can get a virtual private network(VPN), or an Internet Protocol (IP).

Access points

Access points connect the devices to a wireless network without the need for any cables. The wireless network makes it easy for new networks online and provides flexible support to mobile workers. Alongside the router, access points can help in extending the bandwidth to make the network support many devices at long distance. It can also provide proactive security to the user while it is connected to a network.


Wireless networking

There are totally three types of a wireless network – centralized deployment converged deployment and cloud-based deployment.

Centralized deployment

These the most traditionally used deployments in campuses when the buildings are close to each other. It uses a wireless network which provides better functionality.

Convergent deployment

Converged deployment can offer better consistency in wireless and wired connections for small campuses. This network uses an access switch and can perform a dual role of a switch and wireless controller.

Cloud-based deployment

This deployment uses cloud support to manage network devices at a location. The cloud-based system can provide full visibility of the network through the dashboards.
