web hosting glossary

Hosting a website might feel like navigating a maze of unknown jargon. Believe us, We’ve been there. Today, we’ll go through some of the popular web hosting phrases and explain what they mean. This is done in the interests of shortening your web hosting learning curve.


The technique of ensuring that your website functions properly for everyone, including people with impairments, is known as accessibility. Meeting basic accessibility criteria is required for certain company websites and recommended for all. You don’t want any of your guests to feel excluded and leave.

Apache web server

Users receive online content from a web server (usually on their web browsers). Domain Rooster employs Apache, a well-liked, feature-rich, and reliable web server, for practically all of its hosting plans. See these articles for information on configuring Apache.

Automatic response

An auto-responder sends an email answer to the message sender automatically, as the name suggests. The “Out of Office” message reply is among the most prevalent and well-known uses of an autoresponder. Similar to this, you might set up your website to instantly reply to emails received at a certain address, such as info@HostRooster.eu. Please refer to this page for details on how to set up autoresponders in cPanel.


A copy of files or data serves as a backup. You can recover data from a backup in the case of data loss or corruption. Please refer to these articles for further details about data backup.


The pace of data transport is known as bandwidth. The quantity of data transported in a second is often stated in terms of kilobits or gigabits.


A client program known as a “browser” (or “web browser”) parses HTML from a web server and renders it into a page that can be viewed by humans. Web browsers that are often used include Apple Safari, Microsoft Internet Explorer, Mozilla Firefox, and Google Chrome.

You may quickly and simply configure various account settings using the web hosting control panel known as cPanel. All managed to host plans from Domain Rooster come with cPanel. Please refer to these pages for comprehensive information about cPanel and how to utilize it.

DDoS (Distributed Denial of Service) (Distributed Denial of Service)

When several computers simultaneously saturate a target system with network traffic, it is called a DDoS (Distributed Denial of Service) assault. Depending on the setup of the target system, it might not be able to manage the extra traffic, which would affect site performance.


Caching is the technique of temporarily saving your website’s data in order to make it load faster for repeat users. When a visitor initially visits your website, their browser must load every component of the site—all graphics, content, coding, and so on. When you employ caching, you may cache all of that information after the initial visit so that their browser remembers it the next time they return. This can reduce loading time by a few seconds, which may not seem like much but makes a major impact in how visitors interact with your site.


We don’t mean the religious kind—in website terminology, a conversion occurs whenever a visitor performs a desired activity on your site. To name a few frequent instances, this may be clicking a link, signing up for an email list, or completing a transaction. A successful website will be built with conversion rate optimization (CRO) in mind.

Dedicated server

An independent physical server that only hosts one account is called a dedicated server. You have total control over the operating system, resource use, and other factors with a dedicated server. Website performance is typically noticeably faster because the server only supports one dedicated account (as opposed to a shared hosting server, which supports numerous accounts). Customers that want a server with high availability and performance should choose dedicated servers.

DKIM (DomainKeys Identified Mail) (DomainKeys Identified Mail)

The DKIM (DomainKeys Identified Mail) approach is a way to be sure that an incoming email message is from the purported sender and hasn’t been tampered with in transit. The sender uses a private key to digitally sign a message when DKIM is enabled. The recipient checks the message’s signature and retrieves the sender’s public key via DNS. If the signature is invalid, it is considered that the message is forged and is thus spam. SPF and DKIM are commonly used in tandem.

Domain Name

A domain name, such as example.com or HostRooster.net, is a distinctive, human-readable identification for a website. The IP address, which tells a client were to reach the real server, is actually represented by the domain name. See this article for additional information about domain names.

DNS (Domain Name System)

DNS (Domain Name System) is a service that converts human-readable domain names (like example.com) into computer-understandable numerical IP addresses (such as When you purchase a domain name, you or the web host produces a DNS record connecting the domain name to a specific IP address. Refer to this article for further details about DNS.

FTP (File Transfer Protocol) (File Transfer Protocol)

A service for sending files over the internet is called FTP (File Transfer Protocol). You may transmit and receive files to and from a remote server using an FTP client program like FileZilla. To learn more about using FTP, please go to this page.

HTML (Hypertext Markup Language) (Hypertext Markup Language)

The preferred language for building web pages is HTML (Hypertext Markup Language). Upon receiving raw HTML from a web server, a web browser parses it and renders a human-readable web page.

HTTP (Hypertext Transfer Protocol) (Hypertext Transfer Protocol)

HTTPS is an abbreviation for Hypertext Transport Protocol Secure (what a mouthful). It’s a method of determining whether a website has an SSL certificate and can guarantee a secure connection between your web browser and the server. When you’re browsing the web, any URL that begins with HTTPS indicates that you’re on a secure site. It’s an excellent approach for customers to determine whether or not a website is safe to do business with.

IMAP (Internet Message Access Protocol) (Internet Message Access Protocol)

An email server’s authentication process and message retrieval are both handled by the IMAP (Internet Message Access Protocol) protocol. With IMAP, you may access and see your email using a client email program like Microsoft Outlook or Mozilla Thunderbird. Please refer to this page for further details about IMAP.

IP addresses

An IP address is a special number (, for instance) given to a device on a network. A domain name is a name that can be read by humans (for example, example.com) that directs users to a computer’s real numeric IP address.


A client-side scripting language called JavaScript allows website developers to include dynamic information. It functions in the user’s web browser rather than the web server since it is a client-side technology. Most websites utilize JavaScript in some capacity.


Linux is an operating system that is free and open source and functions similarly to Unix. It is widely used in computers worldwide, especially servers, and is renowned for its stability and dependability. Linux is used on all Domain Rooster servers.

Mailing lists

You may send an email message to a number of people at once using a mailing list. Online conversations and the distribution of announcements are frequently done using mailing lists. See this page for additional details regarding mailing lists.

Managed Hosting

Domain Rooster, for example, offers managed hosting, a form of web hosting where the provider manages server configuration changes, software upgrades, and other system management activities. Managed options include shared hosting, reseller hosting, managed virtual private servers and managed dedicated server hosting. Domain Rooster’s managed hosting plans provide cPanel access. If you don’t feel confident managing a whole server yourself, managed hosting is a viable option.


Popular database system MySQL is a part of all Domain Rooster plans. It is frequently used with PHP to create a number of online applications, including MediaWiki and WordPress.


A plugin is a program that extends the capability of software. Plugins are the greatest way for WordPress website owners to add functionality to their website that connects with the CMS. They can include capabilities such as spam filtering, website structure, and eCommerce operations.


Using the free and open-source programming language PHP, you may create dynamic content by inserting code right into a web page’s HTML. PHP is included of each Domain Rooster plan. Please refer to this article for further details about PHP.

POP (Post Office Protocol) (Post Office Protocol)

A mechanism for logging into and collecting messages from an email server is called POP (Post Office Protocol). With POP, you may access and see your email using a client email program like Microsoft Outlook or Mozilla Thunderbird. Please read this article for additional details about POP.

Reseller hosting

The account owner hosts websites for other customers on a reseller hosting plan. Because reseller hosting contains all of the advantages of managed hosting, it is a simple way to launch a business or offer hosting services to others.

Unmanaged hosting

Unmanaged hosting, sometimes known as “semi-managed” hosting, is a style of web hosting in which you are responsible for all server configuration adjustments, software updates, and other system management duties. Unmanaged hosting options include Cloud VPS, Unmanaged VPS, and Unmanaged Dedicated Server hosting from Domain Rooster. Domain Rooster does not provide cPanel as part of its unmanaged hosting services (though you can install it yourself). Managed hosting is an excellent option if you don’t feel confident managing a whole server.

Shared hosting

With a shared hosting plan, the account makes use of other hosting accounts as part of the server resources. It contains all the advantages of managed hosting and is a cheap method to run a website.

SMTP (Simple Mail Transfer Protocol) (Simple Mail Transfer Protocol)

The common mechanism for sending and receiving emails is called SMTP (Simple Mail Transfer Protocol). Refer to this article for further details about SMTP.


All Domain Rooster plans with cPanel access include the Softaculous Auto Installer. With a few clicks, Softaculous enables you to quickly install a number of well-known web programs, including Drupal and WordPress.


Unsolicited bulk (junk) e-mail communications are sometimes referred to as “spam.” There are several strategies and tactics for attempting to lessen the volume of spam that users get in their inboxes, but none of them are currently 100% successful in preventing both spam and legal communications.

SPF (Sender Policy Framework) (Sender Policy Framework)

The SPF (Sender Policy Framework) framework aids in preventing spammers from creating messages that falsely identify users from other domains. The mail servers and IP addresses on a domain that are permitted to deliver email are specified by SPF using DNS records. SPF and DKIM are frequently combined.

SSL (Secure Sockets Layer) (Secure Sockets Layer)

A method for ensuring safe and verified network interactions is SSL (Secure Sockets Layer). It can be used by various programs in addition to web servers and browsers, including mail servers and clients. I recommend reading this post for further details about SSL.

TOP LEVEL domain

The rightmost part of a domain name is known as the top-level domain. The top-level domain, for instance, is.com in the domain name example.com. There are several additional top-level domains, including.org,.net,.gov, and.edu. See this article for additional information about domain names.

Virtual Server

A virtual computer that shares a physical server with other virtual machines is called a virtual private server. You have total control over the operating system setup and root access since the virtual machine behaves as an independent computer (which is an option for managed VPS but isn’t advised). A virtual private server is more flexible and functional than a shared hosting account, yet it is less expensive than a dedicated server. You may see and send email messages from your web browser using webmail. This eliminates the need to set up and install a specific email client program, such as Mozilla Thunderbird or Microsoft Outlook. Additionally, it implies that you may access your email from any web-enabled computer that is linked to the internet.

Website Redirect

A website redirect is the process of directing a URL to a new page. It’s a valuable tool for any website that is migrating to a new domain or for a content audit that ends in the removal or combination of pages. Website redirects are a smart strategy to avoid 404 pages and may easily be set up inside your cPanel. (Yes, we did squeeze three vocabulary terms into one phrase.)

Web Design

Responsive web design is a design style that guarantees a website appears excellent on all device kinds and screen sizes. Because smartphones have become such an integral part of most people’s lives, responsive websites have become the norm. It’s the best technique to ensure that all visitors receive the same information and page components regardless of device. The way text and pictures are sized and structured changes depending on screen size.


Popular open-source blogging software WordPress is free and offers many of customization options. Any Domain Rooster package allows you to install WordPress, either manually or with Softaculous (if your account includes cPanel access).


In web hosting jargon, uptime refers to the percentage of time a web server is operational and error-free. All web servers require maintenance on a regular basis, and as with any technology, there is always the potential of technological faults and unforeseeable situations such as weather catastrophes. However, the most trustworthy web hosting companies will still guarantee their clients uptime of up to 99.9%. Some companies (including Domain Rooster) even provide a money-back guarantee to back up their promises.


A URL is the primary web address of a webpage. It’s similar to a domain name, except that a domain is the address at the website level (for example, www.HostRooster.net), whereas a URL is the address at the page level (for example, https://www.shop.hostrooster.com/products/business). Every page on your website will have its own URL, and it’s great practice to make each URL as clear and straightforward as possible.


WHM is an abbreviation for Web Host Manager, which is a dashboard that allows you to manage many websites from a single location. Having to continuously log in and out of several cPanels is inconvenient for someone who owns or administers multiple websites.
