Most Common Web Hosting Terms & What They Mean (Infographic)

Are you new to hosting and wonder what words like diskspace, bandwidth or uptime really mean?

Then you’re not alone. I was super confused when I signed up for hosting the first time.

Here below is an infographic with common web hosting terms, with explanations of what these words really mean.

I wish there was a visual glossary guide like this around, back then when I got started.

Because for the uninitiated, web hosting lingo can seem like a foreign language, and be a bit confusing.

Especially when you are shopping around for a new web host (like Bluehost ).

Bluehost have created this visual glossary of web hosting’s most common words, acronyms and phrases.

Web hosting glossary

Bandwidth: The amount of data that can be transferred to or from your website each second.

Blog: A regularly updated website or web page. New entries are called posts; posts can be used to drive business to your site or help with SEO. Here’s my starting a blog page.

Cloud hosting: Cloud hosting mirrors your data across multiple storage devices instead of having it reside on just one machine. This redundancy ensures reliability for your site.

CDN: A content delivery network (CDN) is a system of servers distributed across multiple data centers around the world that delivers web content, specifically static files like your website’s images and page styles, to end users.

Control panel: The control panel is the nerve center of your hosting account. This is where you can add new domains, create email addresses, install applications, and manage behind-the-scenes settings.

CMS: A content management system (CMS) is a user-friendly application that you install on a hosting server to make managing a website easier. A CMS like WordPress is particularly great for people without a coding background to get started with a website.

CPU: The central processing unit (CPU) is the brains of your server or computer, executing commands, making decisions, and doing the input/output calculations.

Data center: A data center is a specialized facility that houses thousands of servers that are connected via a network to the Internet.

Dedicated hosting: Dedicated hosting allows you to lease an entire server for your use rather than sharing it with other users or organizations.

DNS: The Domain Name System (DNS) translates easy-to-remember domain names to numerical IP addresses.

Domain name: A domain name, like websitehostingrating.com, is used to identify the location of a particular web page.

Domain registrar: A domain registrar is a company accredited by the Internet Corporation for Assigned Names and Numbers (ICANN) to register and manage domain names.

E-commerce: E-commerce is the practice of buying and selling products or services online.

FTP and SFTP: File Transfer Protocol (FTP) and Secure File Transfer Protocol (SFTP) are used to transfer files between a computer and a server. FTP is especially useful for bulk transfers, so you don’t have to move hundreds of files individually.

HTML: HyperText Markup Language (HTML) is a computer language that tells your browser how to display a web page.

HTTP: HyperText Transfer Protocol (HTTP) is an application protocol for transferring files on the web. Think of it as the foundation of the internet.

HTTPS: HyperText Transfer Protocol Secure (HTTPS) is the use of HTTP over a secure connection, most commonly in conjunction with Transport Layer Security (TLS).

IP address: Each internet-connected computer has at least one IP address, a unique sequence of numbers and/or letters, that serves two purposes: host or network interface identification (who it is) and location addressing (where it is).

Malware: Harmful software that aims to damage, disable, or take control of your computer, mobile device, website, or network. Malware is often used to steal information or hold data for ransom.

Parked Domain: For Bluehost customers, a parked domain is a special feature available in the control panel that allows you to have a new domain display the same content as one of your other domains. Outside of cPanel hosting, a parked domain is a domain name that has been registered but isn’t currently pointing to a website. Organizations often park domains for future use or to ensure they aren’t registered by other buyers.

Payment Gateway: A payment gateway is a service that allows users to authorize credit card payments for e-commerce. Payment gateways often have specific compliance requirements based on your business type and transaction volume.

PHP: PHP (an acronym for Hypertext Preprocessor) is a scripting language designed for web development. It combines dynamic content — prices, comments, or shopping cart contents — with static content — page styles and images — into HTML so your browser can display it.

Plugin: A plugin is a software component that allows you to add a specific feature or function to an existing web program like WordPress.

RAM: Random access memory (RAM) is where your server or computer stores the short-term data it needs to access regularly or quickly.

Server: A server is a powerful computer designed for a specific task. For example, hosting servers are programmed to serve up web content. To ensure reliability and performance, unneeded components are removed, so most servers don’t have video cards, monitors, or even a keyboard.

Shared hosting: Shared hosting is when your website resides on a server alongside other people’s sites. The server’s available resources are shared by all the sites.

Site Backup: Site backup is the practice of copying and archiving data so that you can restore your site in the event of a system failure, cyber attack, or human error.

SSL and TLS: A Secure Sockets Layer (SSL), the predecessor of Transport Layer Security (TLS), is an encryption protocol designed to secure connections between computer systems. For convenience and legacy reasons, both protocols are often referred to as SSL.

SSL certificate: An SSL certificate is used to provide third-party validation of your encryption key, so someone else can’t pretend to be your website. Bluehost customers can purchase an SSL certificate in their control panel.

Subdomains: Subdomains allow you to add a prefix to your domain name (for example, help.bluehost.com) to create an easy-to-remember URL for specific content without having to register additional domains.

TLDs: Top-level domains (TLDs) are the suffixes, such as .com, .org, and .website, at the end of every web address.

Uptime: The amount of time the server is uninterrupted and your website is accessible. This can be measured linearly (154 days uptime) or as a percentage (99 percent uptime over the last year).

Virus: A virus is malware that self-replicates by infecting other programs, servers, or home computers. Viruses are commonly transmitted through email.

VPS: A virtual private server (VPS) is a web hosting server that is partitioned into sections that act as virtual dedicated servers, with each being assigned to only one user at a time.

Web hosting service: A web hosting service provides server space so individuals and businesses can make websites accessible on the internet.

WordPress: is a free and open-source content management system based on PHP and MySQL. WordPress is the most used website building software and powers 1/3 or all websites on the internet.
