Understand Your Network And Hardware

A network is a collection of computers connected together to share resources like printers or network devices. The simplest definition of networking is linking computers to exchange files, printers, and applications.

What is the Internet, and How Does It Work?

The Internet is a vast network that allows computer networks from companies, governments, and universities to communicate with each other. When you visit a website, your computer sends a request to a server that stores websites. Once the request is received, the server retrieves the site and sends it back to your computer.

What is Network Hardware?

Network hardware includes devices like the Optical Network Terminal (ONT), switches, routers, and wireless access points, which allow devices on your network to communicate with each other and with external networks like the Internet.

Optical Network Terminal (ONT)

The ONT, also known as the modem, converts light-based network signals from optical fiber cables into electrical signals that your router can use. An optical fiber cable connects your ONT to your service provider’s fiber network at the Termination Point (TP) installed by your provider. To connect your ONT to your router, you will need to use an Ethernet cable. This device enables you to access the Internet.


A Firewall is a network management system that monitors and filters network traffic based on an organization’s security policies. It serves as a barrier between an internal private network and the Internet, allowing safe traffic through and blocking potential threats. Firewalls are typically used in large organizations to secure their networks.


Switches connect devices like computers, printers, and servers within a network. They facilitate communication both within the network and with external networks.


Routers connect different networks. They enable all the computers within these networks to access the Internet using a single connection. Routers analyze data transmitted across a network and select the most efficient route for it. They help your business connect to the world and protect your data from threats while managing which computers get priority.

Access Points

Access points allow computers to connect to wireless networks without cables. While a router provides the initial bandwidth, access points expand this bandwidth to support more devices and extend the network’s reach.

By understanding these essential components and their functions, you can better appreciate how networks and the Internet operate to keep us connected.
