Home computer networks explained Wi-Fi and wireless access points

Wireless home computer networking from WAPs to Wi-Fi Setting up your home network can get confusing as street slang dominates many forums and internet discussions.  Just about any plastic box with wires coming out of it is often called a modem or a router, in reality it may be neither.

Here at the Guru42 Universe we will do out best to sort through all the geek speak.  It is important to have a basic understanding of all the buzzwords when you are setting up your home computer network.  Depending on your Internet Service Provider and the service you are buying, the device they supply will vary and what you need to connect is not a one size fits all answer.

Your ISP (Internet Service Provider) may provide you with a "residential gateway" that allows you to connect to the internet. You then purchase an internet appliance that is often called a "wireless router" to attach it.  People get confused because many small technology appliances made for home use are actually several devices in one.  One of my pet peeves on is when people use the term "wireless router" to describe a variety of devices. Typically what most people call a wireless router is a combination of a router, a wireless access point, and a network switch.

Wireless Networks in Simple Terms WLAN and Wi-Fi defined

What is Wi-Fi?The term Wi-Fi is often used as a synonym for wireless local area network (WLAN). Specifically the term "Wi-Fi" is a trademark of a trade association known as the Wi-Fi Alliance. From a technical perspective WLAN technology is defined by the Institute of Electrical and Electronics Engineers (IEEE).

In computer networking everything starts with the physical layer, which for many years was a copper wire. The physical layer was expanded to include anything that represent the wire, such as fiber optic cable, infrared or radio spectrum technology.

Wireless network refers to any type of computer network that is not connected by cables of any kind. While cell phone technology is often discussed as a form of wireless networking, it is not the same as the wireless local area network (WLAN) technology discussed here.
