We have put together an A - Z of terms which are commonly used when discussing dedicated server technologies.
The amount of different terms, and the unlimited number of settings and options you can use when you set up your dedicated server can be quite overwhelming, something most find is best left to the experts, but hopefully our short collection of terms will be enough to get you started.


A Record - The A record, as part of the zone file is used to tell the client machine the IP address of the domain name/website they are looking for.


Bandwidth - Bandwidth represents the amount of data that can be, or is being both uploaded and downloaded by the server machine.


cPanel – cPanel is used by the UNIX operating system as a graphical user interface. The GUI allows the server administrator to carry out a wide range of tasks for both setting up and maintaining the server, including the installation of new scripts. Web-based it is quick and simple to use and a popular choice for the owners of a UNIX-based server.


Dedicated Server - A dedicated server is an entire, physical machine. Unlike shared or VPS servers a dedicated server can consume the machines entire hardware. Dedicated server owners have full and unlimited (root) access to the machine.


E-Commerce – E or Electronic Commerce is the term used to describe the exchange of goods and services over the Internet.


Firewall - A firewall can come in both hardware and software form. Hardware firewalls intercept and block unwanted traffic as it travels both in and out of the network. Software firewalls however when installed just protect the host machine on which they are installed. Windows servers use the Windows Firewall (with Advanced Security) whilst UNIX-based operating systems most commonly use IP Tables.


- A gateway is used to exchange information across a network when incompatible protocols are being used. Through a combination of both hardware and software the gateway connects the two different types of network and forms a “bridge”, allowing a translation to occur.


Host – The host (or web host) is the company from which you rent your server.


IP Address - The IP address is the unique number each server has on the Internet. Like your own home’s physical address, it is unique throughout the world, just as the IP address is throughout the public Internet. The two current versions are IPv4, which is slowly being replaced by IPv6.


Java - Java is a object-oriented programming language often used to create network-based applications. Java unlike other forms of computer language runs within it’s own instance of a virtual-machine, making it safer to use. It can also be used to create embeddable web-page interfaces known as Applets.


Kernel – The kernel is at the heart of the operating system. Responsible for handling the initial booting up of the computer, its main role is to handle a range of low-level tasks. It is on-top of the kernel that the higher, more user-friendly elements of the operating system are built.


Load Balancing - Load balancing describes the method of connecting multiple computers together in order to distribute overall workload in an efficient manner. Each component computer is responsible for a separate part of the overall system, and can be optimized to increase its performance as a component part.


MX Records
–Made as an entry in the DNS file, the mail exchange (MX) record stipulates which mail server is responsible for handling your domain’s email.


Name Server – The name server is the computer that maps each human-memorable domain name to the IP address where the website is hosted.


Operating System - The operating system is the software which allows the user to control the computer. The two most common operating systems used for servers are the Unix based operating system (such as CentOS, Debian and Ubuntu) and Microsoft’s Windows Server edition.


Plesk - Parallels Plesk Panel is a web-based graphical user interface used by server administrators. It is used to set up new websites, email accounts, reseller accounts and DNS entries. The administrator can create templates (for the clients and the websites) so that resources can be allocated accordingly.


Quarantine - The quarantine period follows a domain name’s redemption period. During the quarantine period a domain name can no longer be registered by the original owner, but is also not yet available on sale to the general public.


RDP (Remote Desktop Protocol) - RDP the Remote Desktop Protocol is used by web servers running the Microsoft Windows operating system. It is a way for users to connect to the server from anywhere on the public internet. It’s graphical user interface allows the user to see the screen just as they would if sat physically in front of the machine itself.


SSL (Secure Sockets Layer) - SSL is used to encrypt data. Secure SSL connections are often used for transmitting sensitive information (such as credit card numbers) securely across the public Internet. SSL certificates can be installed on your server so that visitors can use the secure https protocol.


Traffic - Traffic is most commonly used to describe the number of visits (or “hits”) a website receives.


URL (Uniform Resource Locator) – The URL is the human-friendly address/location of a particular resource, for example the page of a website.


VPS (Virtual Private Server) – A VPS is a type of web server which shares the resources of a dedicated server with other VPSs hosted on that dedicated machine. The dedicated server’s resources are shared between the VPS servers, allowing for one physical machine to run as two or more “virtual” machines. Each VPS is completely separate from the other and runs as a regular normal single server would, but without access to the host machines complete amount of resources.


Whois – Whois is a public internet “lookup” service that allows people to find out who are the registered owners of a domain name.


Zone File - The zone file is a group of files held by the domain host or name server. It is this group of files that designate a domain, subdomains, and domain mail server.
