If you’ve ever listened to a tech buff talk about their passion, it may have sounded like they were speaking a different language. Tech jargon can be intimidating and hard to understand.

Guide to understanding tech jargon

Tech jargon is the language that people in the tech industry (or even tech enthusiasts) use to communicate with each other more easily. If you’re breaking into the industry or just trying to understand what your kids mean by “blockchain,” this guide is for you.


Megabits per second (Mbps) is a unit of measurement for network bandwidth. In other words, this measurement shows you how fast a network or internet connection is. Each unit represents the capacity to transfer one million bits per second. If you want to learn more about your connection and find out what speed is right for you, check out our article on understanding internet speed.


One of the more delicious technology terms, cookies serve an important purpose. Cookies are small files sent to your browser from the sites you visit. When you visit a website, you probably click “allow cookies” without thinking. When you do this, you’re giving these files permission to monitor the sites you visit and the pages you click on. Retailers use this tool to track items you’ve looked at, added to your cart, or purchased. Some sites might even store your username and password so they will automatically fill in the corresponding fields when you return to the site. In other words, cookies improve your experience and help retailers suggest new items to you.

Blockchains, such as the one that Bitcoin operates on, have been around for a little more than a decade. Each year, there are more types of cryptocurrency for sale and new ways to use them. Cryptocurrency such as Bitcoin and Ethereum travels on the blockchain when people buy, sell, or trade it. Blockchains are basically unalterable digital ledgers that create and track records, assets, and transactions. A blockchain database stores data by encrypting it with a hash. Every subsequent transaction records this hash, chaining every transaction together. Basically, it makes verifying transactions or records easy, but it’s very difficult to change or alter the information.


HTML, or HyperText Markup Language, refers to a common coding language that developers use to design of a webpage. HTML uses “markup’ to annotate text, images, and other content for display. If you’ve ever seen text such as <header>, <title>, <img>, or <footer>, you’ve seen HTML markup.

IP address

An Internet Protocol Address, better known as an IP address, is a unique string of numbers assigned to your internet-connected device, such as your computer. Your network uses the IP address of your device to communicate with other computers. Basically, it’s a digital address for your computer that helps internet providers deliver content directly to you (through your network devices, such as routers). To find your IP address, simply search “what is my IP address” on Google, and it should pop right up.

We use them all day long, but do we even know what the acronym stands for? Uniform Resource Locators, or URLs, are basically the addresses given to any resource on the web. When you’re searching for a specific website, such as the CenturyLink Discover blog, you type the URL into the search bar to automatically load helpful blog articles and videos.


You may have heard the term “firewall” when researching internet security. But do you know what it means? A firewall is a network security device that monitors your network traffic to decide whether to allow or block certain traffic. They’re the first line of defense against cybercrime. Firewalls can be configured into your hardware or software. You can also access them on certain networks thorough public cloud or private cloud.
