45+ Web Development Terms

Web Development is an ever-changing field, and it’s sometimes hard to know what all the jargon means. This post provides a comprehensive dictionary of terms that will help you understand everything from CSS classes to web servers. This glossary is perfect for beginners looking to learn more about web development in general, or for people who are interested in specific technologies like PHP, Ruby on Rails, and Joomla!

  • Agile: Agile is a set of principles for software development. It includes techniques like Test-driven Development, timeboxing and iterative modeling.
  • Algorithm: An algorithm is an ordered list of instructions that accomplishes some task. Algorithms are at the heart of computer programming; every program you use on your PC or Mac has one behind it.
  • API: An API, or Application Programming Interface, is a set of routines and protocols that allow programmers to use the services provided by another program.
  • Application: A computer application is a software package designed for an operating system’s environment. Applications are often installed on your device alongside other programs in order to run them; however they can also be downloaded from App Stores such as Google Play Store and Apple’s App Store.
  • Adaptive design: Adaptive design (also known as responsive web design), uses fluid grids, flexible images and CSS media queries to deliver content based on the viewing device being used – meaning it adjusts automatically when you switch-between desktop PC/laptop screens and mobile phone screens
  • Bootstrap: Bootstrap is one of the most popular front-end frameworks for developing responsive, mobile-friendly websites.
  • Backend: The backend is the back end of a website. It contains all the files and databases that are not seen by visitors to your site.
  • Browser: A browser is an application used to find information on the internet. There are many different types of browsers, including Chrome, Safari, Internet Explorer (IE), Edge.
  • Bug: When programmers make mistakes in their code they call it a bug; this can cause problems when trying to run or use software.
  • Cache: Caching refers to storing frequently requested data so future requests from other users needn’t result in as much processing work – essentially speeding everything up! Caches come in two forms; page caches and object caches.
  • Code: Computer code is a set of instructions written by programmers in order to make software do what they want it to do. It’s the blueprints for how machines should behave and perform tasks .
  • CSS: Cascading Style Sheets are used by designers when building websites – these control the layout, colors and structure (among other things) on pages that visitors see.
  • Data structures: Data structures are ways data can be stored in memory or on disk so that its content may be accessed more quickly than if it were just sitting there like an unwrapped gift! Some popular types include arrays, linked lists and hash tables.
  • Debugging: Debugging involves locating errors within computer programs and fixing them before releasing the software to the public.
  • Deployment: The deployment stage is where a website’s code and content are put onto one or more servers. These machines host your site, meaning they provide you with an always-on connection that gets visitors’ pages loaded up quicker than if it were coming from their own computer.
  • Documentation: Documentation refers to all of the materials needed for programmers and other people who work on programming projects to know what they’re doing – without documentation, these folks can’t do much! There are many different types but the most common include design documents (or wireframes), system specs, user manuals etc…
  • Domain name: A domain name is like an address for websites; this tells browsers how to find them online ! The top-level domain for all websites is “dot” – so .com, .org.uk etc..
  • Ecommerce: Ecommerce refers to using your website to sell products or services online.
  • Engineering: Software engineering is a profession that deals with the design and development of computer applications; it’s closely related to programming but takes in an even wider range of tasks including hardware components as well! Some programmers have a background in software engineering because the two fields are very similar.
  • Forms: Forms on web pages allow users to input data into databases automatically (or give feedback about something) without having access rights to their account .
  • Frontend: Front end development means working on what visitors see when they visit your site; this includes writing HTML/HTML Markup, CSS and JavaScript.
  • Git: Git is a type of version control software that developers use to keep track of changes made to their code. It also provides an easy way for other people on the team to collaborate.
  • Gzip compression: Gzip compression saves space by removing unnecessary information from files – it’s one of many technologies used during the delivery process! Compression may make pages slower but they will take up less storage space (and time!) in your browser or on your hard drive.
  • Hosting: A hosting company host websites so you don’t have to worry about managing IT infrastructure yourself; this includes servers, data centers etc. They are contracted with networks like Akamai, Amazon Web Services and Rackspace.
  • HTML: Hypertext Markup Language, or HTML for short. This is a markup language used to build web pages.
  • Identity management: Identity management is the process of identifying who a person is – this might be done by logging into a website with existing account details, providing their email address and waiting to receive an activation link in response. User accounts are often tied up with all sorts of personal information such as credit card numbers etc. which makes it especially important to protect them!
  • JavaScript: JavaScript is one type of programming language that web designers can use while working on frontend development; its main job here is interacting with visitors’ browsers when they visit your site so you don’t have to rely solely on forms (which may not work if someone doesn’t have access rights)
  • jQuery: jQuery is a JavaScript library that allows designers to create interactive web pages; it’s often used by developers who work on frontend design because of its versatility.
  • Languages: There are many different programming languages for use in the world today but some popular ones include Python, PHP and Ruby.
  • Libraries: Libraries give programmers shortcuts when writing code so they don’t have to do everything from scratch each time – there are far too many functions out there! Some common libraries include Bootstrap, Foundation or jQuery UI which make things like navigation bars easier to build (and adapt).
  • Minification: Minifying your website can save you space – this means taking unnecessary information out of files until they’re as small as possible.
  • Mobile-first: Mobile first means that you design for mobile devices before designing for desktop or laptop – this is important because so many people are browsing the internet on their phones now! It’s also possible to have a responsive website which adapts depending on what device someone is using (though it may be slightly more difficult, and expensive).
  • MVP: Minimum viable product refers to how much code developers need in order to test an idea; they then use feedback from early users to decide whether they should add more features. MVP has become popular as the best way of testing out if there will actually be a demand for your product (before going all in!)
  • MySQL: MySQL is one type of database management system used by web developers. Databases are basically a way of storing information in tables which can be used to find out how many times particular words have been searched for etc. MySQL is just one example but there are other types too – some examples include MongoDB, Microsoft SQL Server or Oracle Database (which may be more appropriate depending on your requirements).
  • PHP: PHP is a programming language that’s often used for web design with WordPress. It also has the capability to create interactive websites – it was designed to be easy and quick so developers can focus on what they’re working on rather than worrying about how things are going, which makes it perfect for beginners!
  • Plugin: Plugins give you access to new features without having to start from scratch each time; this might include fields or buttons so your website becomes more dynamic depending on user input (rather than just being static). For example, if someone needs a contact form then there would probably already be plugins available online for them or their developer could make one themselves quickly and easily.
  • Python: Python is an open source machine-readable language that many people use to create programmes; it’s often used with programming languages like Django or Ruby on Rails.
  • Resolution: Resolution refers to how many pixels there are in an image for a website – this is important because when people visit your site, their screens may not be displaying the same number of pixels so you need to make sure everything looks alright (this can get more complicated if someone has access rights and needs higher resolution). Responsive design means that you display things differently depending on what device they’re using – which might mean putting less information onto smaller devices but making content bigger when viewed from further away.
  • Ruby: Ruby is another example of a machine-readable language that developers use for web development; its main job here is interacting with visitors’ data. Ruby on Rails is a framework which makes it easier to create web applications – this can be done by following basic conventions which give you a head start (rather than having to write every line of code yourself)
  • Sitemap: A sitemap is basically an overview of the content your website has, and in what order these items are laid out; they might make things easier for visitors if they’re looking for specific information.
  • Software stack: Software stacks define how different pieces of software work together or complement each other – often used with databases such as MySQL so that developers don’t need to worry about them too much because everything will just go smoothly (though there’s still plenty to learn!)
  • SSL: SSL stands for Secure Sockets Layer and is often used by web developers to encrypt data – this means that messages sent from one system to another are secure.
  • Text editor: Text editors can be software such as Notepad or Word, or they can simply be a text document on your computer; either way, it’s where you write the code for your website (for example PHP).
  • UI Design: UI stands for “user interface” which defines how someone interacts with their device. UX design refers to how easy something feels when interacting with it – both have been shown in scientific studies to make people more likely to want what they’re looking at!
  • Version control: Version control is about making sure everything stays organised so if anything goes wrong then things will be easy to fix.
  • Web App: A web app is basically a website that runs on the internet; this might include things like Facebook or Twitter. If you’re developing one, you’ll need to make sure it has an interface and also that people can log in (this usually requires having both front-end and back-end code).
  • Wireframe: Wireframes are often used as blueprints for building websites – they show how everything should be laid out from start to finish so developers have something visual to work with.
  • Web Development: Web development is what happens when someone builds their own site using programming languages such as HTML, Javascript, CSS etc.; though if all of these sound too complicated then there’s always CMS systems which will build your site for you!
