Wi-Fi vs Internet

This is the Internet as it should be known.  

Wi-Fi: As mentioned in Wired Networking of this series, Wi-Fi is just an alternative to network cables as the way to connect devices of a local area network (LAN). By the way, most networking terms used in this post have been explained in Wired Networking; others will be explained here. Prior to Wi-Fi the only way to connect devices together was to run the physical network cables between them, which is very inconvenient.

The owner is in total control of the Wi-Fi network. He or she can change the name of the network, the password, the number of connected clients, allowing them to exchange data with one another or not, and so on.

This means involved devices can always work with one another to provide data sharing, printing, local media streaming, local network backups, and so on.

To connect a home Wi-Fi network to the Internet, the router needs to be connected to an Internet source, such as a broadband modem, via its WAN port. When this happens, the Wi-Fi signal of the local network will also provide the connection to the Internet for its connected clients. So Wi-Fi is just one way to bring the Internet to a device.

Internet: Generally known as the wide area network (WAN), the Internet connects computers from around the world together. In reality, as far as the current state of how the World Wide Web is run, the Internet actually connects many local networks together, via many routers

The Internet's speed has progressively increased in the last decade. The most they can do is pay for the desired connection speed and hope that they get what they pay for

For a Wi-Fi network, the speed of the local network depends on the standards used by the Wi-Fi router (access point) and the connected clients, and can sometimes be slower than a fast broadband Internet connection.

Types of broadband Internet connections

• Wired Internet (residential broadband): This is when you connect to the Internet using a physical cable, be it a telephone line (DSL) or a cable line (cable), or a fiber optic line (FIOS)
• Satellite Internet (satellite broadband): This is similar to the wired Internet but instead of connecting to the service provide via a cable, the home network connects to a satellite disk on the roof.
• Cellular Internet (wireless broadband): Cellular Internet uses the cell phone signal to carry data and connect the supported device directly to the Internet.
• Cellular Internet is generally expensive because it tends to come with very low monthly data caps (about 5GB or less) and customers have to pay more than the fixed monthly cost when they go over the allowance. This type of Internet access is very popular with mobile devices, including smartphones and tablets.

The Verizon version of the new iPad offers the Personal Hotspot feature, which enables users to share the tablet's 4G connection with other Wi-Fi devices.

The combination of Wi-Fi and Internet 

If you have a laptop, such as the MacBook Air, the best way to connect it to the Internet is via Wi-Fi since the machine doesn't come with a built-in network port, nor does it support a cellular connection. At home or at the office, this can be done via a Wi-Fi-enabled router that connects to a residential broadband Internet connection. When you're on the go, however, you can't bring the router or especially the residential broadband Internet connection with you.

This is a little device that connects to the Internet using a cellular connection and then shares that connection via its own built-in Wi-Fi network. As mentioned above, the prime example of the combination of Internet and Wi-Fi is a mobile hot spot, such as those on this list.

A mobile hot spot lets more than one Wi-Fi-enabled device to share a single cellular connection.
