The Internet vs. the Web
The Internet is actually millions of computers interconnected in a global network. (Interconnected +
Network = Internet.) All of these computers can talk to each other to send and receive data around the world as fast as you can favorite a tweet.
The web, on the other hand, is the system where some (but not all) of that data is kept in the form of special documents. These documents are linked together and more commonly known to you and me as web pages.
To put it simply, the internet is the equipment and connections, and the web is the information. Fun fact: While “world wide web” was the hottest term for the web a few years ago, Millennials prefer to call it “the cloud."

HTML vs. CSS
Speaking of the internet, here’s a bit more about how the websites on it are made. HTML — or HyperText Markup Language — is the language used to write web pages. HTML is made up of “elements” (paragraphs, headers, lists, links, and the like), which give each web page structure and contain the content of the page itself (text, images, videos, and so on).
CSS — or Cascading Style Sheets — tell web browsers how to format and style an HTML document. In other words, CSS is what makes HTML look good. Using CSS, you can give a web page its own font, text styles, colors and, with the newest CSS version (CSS3), even multiple backgrounds, 3D transformations, and awesome animations.
To put it simply, HTML holds the content in place, and CSS makes it look pretty.
Front End vs. Back End
The back end of a website is the part of a website that makes it work. It includes applications that tell websites what to do, servers where websites get data from, and databases where information websites use is stored.
On Twitter, for instance, the look of your feed is the front end, and all the data is stored in the back end.
App vs. Software
Speaking of telling computers what to do, you’ve probably heard the term “application” before. In a nutshell, an application, or app, is a program or set of instructions that you can use to do certain things on your iPhone or Android.
The general term for any instructions for your computer, tablet, or phone is software. So, apps are just one type of software. But, system software—like operating systems (think iOS7 or Windows 8), drivers (controls for your printer or speakers, for example), or utilities (like anti-virus or backup)—are a different type of software that run your computer as a whole and make it possible for you to use all those apps you’re addicted to.
That means: All apps are software but not all software is an app.
UX vs. UI
Even pros can get mixed up about these two abbreviations. UI — or User Interface — is how a product or website is laid out and how you interact with it: Where the buttons are, how big the fonts are, and how menus are organized are all elements of UI.
But UX — or User Experience — is how you feel about using a product or a website. So, your love for the way the new Apple Watch looks or your excitement that there’s finally a tablet-sized iPhone to watch those Corgi videos you’re obsessed with are reflections of UX.
So the new look of the Facebook news feed involves a change to UI, and the way you navigate that new page is the UX.
