Networking & WiFi are the primary technologies that allow communication and data exchange between different devices around the globe. While networking is a broad term incorporating numerous ways of connecting devices, WiFi on the other hand is a specific type of wireless networking that is now widely used in homes, offices, public spaces, and almost every work environment. Enrgtech offers top-of-the-line networking and WiFi equipment, including modems, routers, AV patch panels, network hubs and more, at competitive prices for customers in the UK and worldwide.
Understanding Networking
Networking is a broader term that refers to the interconnection of various devices, including computers, smartphones, and servers, to exchange resources and information. Networks are usually classified based on their size, scope and purpose of use. The most common networking methods used in the world include the following:
- Personal Area Network (PAN): Connects devices within a small area (e.g., the connection of a Bluetooth module between a smartphone or headset).
- Local Area Network (LAN): Connects electronics within a limited area, such as a home, office, or school.
- Wide Area Network (WAN): Connects devices over a large geographical area, e.g., the internet.
What is WiFi?
WiFi is the short term used for (Wireless Fidelity) which is a wireless networking technology that uses radio waves to exchange data and information between multiple devices. It works based on the IEEE 802.11 standards and has modernised the technological landscape of wireless LANs.
Necessary Components of a WiFi Network
- Wireless Router: A component that serves as a central hub for the WiFi network, linking multiple devices to the internet or other networks.
- Wireless Adapter: A hardware component in a device that enables it to connect to a WiFi network.
How Does WiFi Work?
- A wireless adapter in a device drives out a radio signal.
- The wireless router obtains the signal and sends it to the network.
- The router also receives signals from the network and transmits them to the device.
What are the Potential Benefits of Using WiFi?
- Accessibility: Enables devices to connect to the network without physical cables.
- Flexibility: Allows users to move around while staying connected to the network.
- Ease of Use: Relatively easy to set up and use.
Bottom Lines
Networking & WiFi have become the key method for communication, information exchange, and access to online resources. They play a crucial part in various aspects of modern life, from personal use to business operations and industrial automation. WiFi networks must be secured with solid security measures and encryption protocols (such as WPA2 and WPA3) to avoid unauthorised access and protect confidential data.
