To learn more, refer to What Is GitHub? A Beginner’s Introduction to GitHub.
HyperText Markup Language (HTML) is the standard markup language used to create and structure content for the World Wide Web. It doesn’t allow variables or functions, so it is classed as a markup language instead of a programming language. HTML provides a set of tags or elements that define the structure and semantics of a web page’s content. Web browsers interpret these tags to render text, images, links, forms, and other elements, allowing users to interact with and navigate web pages. For more information, refer to What Is HTML? A Beginner’s Guide.
An HTTP request is a message that is sent by a client, such as a web browser to a server to request a specific action or resource. When you visit a website, your browser makes HTTP requests to the server, and the server responds by delivering the data and files the site requires to load in your browser. HTTP is the protocol used for communication on the World Wide Web, defining how messages are formatted and transmitted between clients and servers. To learn more about HTTP requests, refer to What Is an HTTP Request?
The Internet of Things (IoT) is the interconnected network of physical devices such as computers, sensors, vehicles, and machinery. The devices collect data, and the network enables them to communicate and share information. IoT use includes smart homes, manufacturing, healthcare, agriculture, etc. For more information, refer to What Is IoT (Internet of Things)? Everything You Need to Know.

To learn more, refer to What Is MySQL? A Beginner-Friendly Explanation.
A nameserver is a type of server that is part of the DNS infrastructure. It stores and manages DNS records for domains, which translate domain names into IP addresses to help direct traffic on the Internet. When you enter a domain name in your web browser, such as www.example.com, your computer needs to find the corresponding IP address to connect to the server hosting the website. Your computer sends a DNS query to a nameserver, and the nameserver replies with the IP address, which means your computer can now connect to the server hosting the website. For more information, refer to What Is a Nameserver? Why Are Nameservers Important?
NGINX (pronounced “engine-ex”) is an open-source web server, reverse proxy server and load balancer. It is known for its high performance, efficiency, and scalability, making it a widely used choice for serving web content and optimizing the delivery of web applications.

To learn more about PostgreSQL, refer to What Is PostgreSQL?
A proxy server acts as an intermediary between devices (such as computers or smartphones) and other servers on the internet. If you use a proxy server, when your visitors make a request for a resource (such as a web page or a file), the proxy server forwards that request to the destination server on behalf of the visitor. The server then sends the response back to the proxy server, which, in turn, sends it back to the visitor. Proxy servers can provide anonymity and privacy as they hide the visitor’s IP address from the server; they can also be used to filter content, cache resources locally, and much more. To learn more about proxy servers, refer to What Is a Proxy Server Used For? (And How Does It Work?).
Pseudocode combines natural language and structured programming language conventions to represent algorithms, functions, and other processes. It is not an actual programming language; it allows developers to outline a solution in a more human-readable format so they can focus on the logic and structure of their algorithms without being concerned about the specific syntax requirements of a particular programming language. For more information, refer to What Is Pseudocode and How Can It Improve Your Programming?
A reverse proxy is a server or software component that sits between client devices (such as web browsers) and a web server. Unlike a traditional forward proxy, which handles requests from clients to external servers, a reverse proxy manages requests from clients to one or more backend servers. It acts as an intermediary between clients and backend servers, forwarding client requests to the appropriate server and returning the server’s responses to clients. Reverse proxies are typically used to enhance the performance, security, and reliability of the web server. To find out how to set up a reverse proxy for your website, refer to How To Set Up a Reverse Proxy (Step-By-Steps for Nginx and Apache).
Secure File Transfer Protocol (SFTP) is a secure version of FTP. It is a network protocol that provides a secure and encrypted way to transfer files between computers over a data network that uses Secure Shell (SSH) to encrypt the connection. SFTP is the only supported file transfer protocol at Kinsta; for more information about using SFTP at Kinsta, refer to SFTP. For more details about how SFTP is more secure, check out the difference between FTP and SFTP.
An SPF (Sender Policy Framework) record is a type of DNS (Domain Name System) record that helps prevent email spoofing and phishing by specifying which mail servers are authorized to send emails on behalf of a domain. SPF is an email authentication method that allows domain owners to declare a list of authorized mail servers permitted to send emails using their domain name. SPF is one of several email authentication methods, and it works alongside DKIM (DomainKeys Identified Mail) and DMARC (Domain-based Message Authentication, Reporting, and Conformance) to enhance email security and prevent email-related abuse. For more information about SPF records, refer to What Is an SPF Record? A Complete Guide.
A taxonomy is a way of organizing and classifying content in WordPress. It allows you to group and categorize content types to make it easier for your readers to find related content. There are 2 main taxonomies:
- Categories: These can be used to create a hierarchical structure with parent and child categories, such as a parent category called “accessories” with child categories “hats” and “gloves”. You can assign more than one category to a post.
- Tags: Tags don’t have a hierarchical structure. Each tag is independent and can be used for specific keywords or topics. You can assign multiple tags to posts.
You can also create custom taxonomies for specific organizational needs. To learn more, refer to What is a Taxonomy? WordPress Taxonomies Explained.
Top Level Domain (TLD) is the last part of a domain name, for example, .com, .net, .org, or .io. They link your domain name to web servers and are an essential part of the Domain Name System (DNS), the hierarchical naming system used to identify and locate resources on the internet. To find out more about TLD, refer to What Is a TLD? Top-Level Domains Explained. To help you choose the right domain extension for your site, refer to What Are Domain Extensions? (And How to Choose a Domain Extension).
A trackback is used to notify another website that you have linked to one of its posts. It is a way for websites to communicate when one site references or links to content on another. Trackbacks are a form of acknowledgment and provide a means for content creators to see who links to their posts. Trackbacks and pingbacks are similar in purpose but differ in how they communicate. Trackbacks use HTTP POST requests, while pingbacks use a standardized XML-RPC protocol. Trackbacks can be susceptible to spam, and website administrators may need to use anti-spam measures to filter out unwanted or irrelevant trackback notifications; due to this, many websites choose to disable trackbacks and opt to use other communication methods, such as pingbacks or social media sharing. To learn more, refer to What Is a Trackback?
Time to Live (TTL) is a time limit for how long your computer remembers where a website is located. It is a setting on the DNS that determines the duration the website data is available on a network before the router clears it. When the TTL expires, the router needs to retrieve the information again to ensure you have the latest information from the website. TTL is also used on Content Delivery Networks (CDNs) to cache data on the servers; this determines how long the CDN servers retain data for your website before retrieving updated information. To learn more about TTL, including how to choose and change your TTL, refer to What Is TTL (And How Do You Choose the Right One)?
A Uniform Resource Identifier (URI) is a string of characters that provides a unique identifier for a resource. URIs are used to identify and locate resources online or in other contexts where resource identification is necessary. Both URLs and URNs fall under the broader category of URIs. They provide a standardized way to uniquely identify and reference resources, whether they are documents, services, or other entities.
A Uniform Resource Locator (URL) is a reference or address used to access resources on the Internet; it provides a standardized way to access and share resources across different devices and platforms. Web browsers use URLs to navigate to web pages, access files, or interact with various online services. For more information, including what makes up the structure of a URL, refer to What Is a URL? The Anatomy of a URL, Permalinks, SEO, and More.
A Uniform Resource Name (URN) is a specific type of URI used to provide a persistent and location-independent identifier for a resource. Unlike URLs, URNs only provide a unique name for a resource; they do not specify a location or how to access it.
