IT Terms you should know for answering “How does the internet work”

And like any industry, there’s new lingo you should know.

  1. IT – stands for “Information Technology”
  2. Network – links two or more devices that are in order to share electronic communications. Devices on a network are linked via cables, telephone lines, radio waves, and satellites.
  3. ISP – Internet Service Provider. Examples are Verizon, spectrum, and optimum. These service providers install the physical wire from their facility to your home, office, or business.
  4. Modem – this device sends the request for information through the ISP, then waits for the request to be fulfilled by the server. Lastly, the info is sent to the router and to your phone.
  5. Router – Creates a network that allows wired and non-wired devices to communicate with one another without going through the internet.
  6. Wifi – Wireless Fidelity. – Devices connect to the local network over short-length radio waves.
  7. WAP – The Wireless Access Point transmits and receives the wifi radio waves for devices to connect back to the network. Although known as another popular music song.
  8. Bandwidth – this lists the amount of upload/download speed your ISP is providing. Think of this as a lane on a highway, the more data you send, the more lanes you’ll need.
  9. Latency – This describes the round trip time from the browser to the server. The time it takes for your request to hit the server and return to your screen. The lower the latency the faster your pages, show, or download.
  10. IP Address – “Internet Protocol” address. The “address” part refers to a unique number that gets assigned to the device you’re are using to request and receive data from a network. To clarify, it just like a return address on a letter you’d send out.
  11. Bluetooth – Not WiFi but another way of transmitting data short distances and communicating directly from one device to another. When you send music to a speaker, it’s exchanging the data of the song through Bluetooth radio waves from your phone directly to your speaker, not through the internet or network.

WhatismyIPaddress.com does a great job at breaking down this process.

Now, a quick visual of the process seen below.

Firstly, your ISP provides an IP address and allows you access to the internet.

Next, you request data (this is your website, social media account, Netflix show) from the server on your phone or device.

Lastly, the host server sends you the data/information back to you to read, view, or watch via the hardware.

IT Questions to ask yourself:

  1. Does my home/office/business have enough bandwidth to support our needs?

  4. I have a growing real estate portfolio, how should I set up my internet connection for my future needs with a budget in mind?

Fun IT Facts 

Check out this cool video about the transatlantic wire that connects North America and Europe. The transatlantic wire is a physical wire that crosses the ocean floor and connects North America to Europe. The idea started back in the 1800s and is of such importance that growing with tech companies like Google, Apple, and Amazon are running their own lines at the bottom of the ocean.
