ActiveSync is synchronisation software developed by Microsoft.

It uses the Exchange ActiveSync (EAS) protocol which you can get with a paid license.

This protocol allows you to synchronise emails, contacts, calendars, tasks and notes with the Exchange server.

Various devices are compatible with the ActiveSync protocol, as are the latest versions of Android, iPhone, Symbian and BlackBerry platforms.

Cc & Bcc

Acronyms used in most email programs.

Cc: Carbon copy

The list of recipients can be seen by anyone copied into the email.

Bcc: Blind Copy

The list of recipients cannot be seen by anyone blind copied into the email.

Email client

An email client is software used to read and send electronic mail (email). Usually these are heavy email clients but some Web applications (Webmail) also offer the same possibilities.

The purpose of this software is to give a user access to their electronic mailbox and send and receive messages. Here are some examples of an email client: Thunderbird, Outlook and Mac Mail.


Acronym for Internet Service Provider.

Example: (Sky Broadband, Virgin Media, OVH).


IMAP is a protocol used to retrieve emails stored on a mail server.

Its purpose is similar to POP​​, the other main protocol for mail retrieval.

But unlike the latter, it was designed to allow messages to remain on the server.

IMAP protocol is used more to synchronise mail, whereas POP​​ is used to retrieve mail.

Mailing list

The Mailing-List is a chat system using email, allowing to exchange e-mails within a community of users defined beforehand.


MAPI is a proprietary Microsoft API.

It is used in Microsoft Outlook, for example. It allows you to communicate with mail servers, such as Microsoft Exchange.

Its purpose is to create, manipulate, transfer and store email messages.


OWA (Outlook Web Access) allows users to access their mailbox from a web browser. It is optimised for touchscreens. You can also access your contacts and calendars. You can get this as part of the Exchange Offer and cannot be used with an "OVH email" offer.

OWA is to Exchange what RoundCube is to "OVH email".


POP​​, also known as POP3 is a protocol for retrieving emails from a mail server.

This protocol connects your email software (Outlook, Mac Mail, Thunderbird etc...) to the mail server.

Your mail client will retrieve the emails from the server.

It can leave a copy of this email on the mail server, depending on the settings you have configured on your software, such as not to keep a copy, or keep a copy for a week.


The concept of port "software" allows a computer to distinguish different users.

You will need to change your software ports when configuring your email client. Depending on your configuration, you need to change the value of the ports on your mail client.

Mail server

A mail server is server software for electronic mail (email). Its purpose is to transfer email messages from one server to another.

A user is never in direct contact with this server - they use either a mail client or a web application (Webmail) to contact the server to send or receive messages.


SMTP (Simple Mail Transfer Protocol) is a communication protocol used to transfer electronic mail (email) to the mail servers.

SMTP is a simple protocol. You specify the sender and the recipient of the message, and then, usually after having verified their existence, the message body is transferred.

It is possible to test an SMTP server by using the "telnet" command on port 25 of a remote server.


SSL is a security protocol for internet exchanges. It allows you to ensure the privacy of exchanged data. You can combine IMAP or POP​​ protocols with the SSL security protocol.


Webmail software is a mail client which runs on your web browser. It acts as an interface between a mail server and a web browser (Internet Explorer, Firefox, Chrome, Opera), in contrast to the heavy client (Outlook, Thunderbird, Mail), which allows you to acess your emails using software installed on your computer. Webmail makes it possible for you to check your emails wherever you are, as long as you are connected to the internet.


A database allows you to store information on your website or application.

Usually, dynamic information from the entry form (from the website or its management interface) is stored in the database. For example, if articles in your blog need to be changed, the article text will be registered in a database.

Most current CMS (WordPress, Joomla, PrestaShop) use a database.


CHMOD (abbreviation of change mode).

These are access permissions to files stored on your host server that can be changed.

Usually for files, the value of CHMOD is 644 or 604. For files, it is 755 or 705.

In the event of hacking, our robot can change the permissions on your host server's root with 700 command. In this way, the administrator of the host server still has FTP access. However, users that connect to the site will no longer be able to see its contents and will therefore be protected.


Acronym of Content Management System. This software is developed to help you build your website, forum, slideshow, blog or online shop. It is managed using forms in a specific interface. The information is then stored in the database. WordPress, Joomla and Prestashop are examples of some CMS.


Cron tasks allow you to automate certain tasks, such as scheduling the time for a file to perform a specific task. The file will contain a script developed in PHP or PERL type language.


Remember that your domain name uses the DNS servers displayed by your current registrar.

A DNS zone is displayed on your current registrar's DNS servers.

In the DNS zone, you will find all services associated with your domain (site hosting, emails). Here, you can select your host server's IP address or the email servers you want to use, for example.


The domain is your website address.

It enables your users to find your website.

The domain links your host server and your emails via the DNS zone and therefore to your current registrar's DNS.


FileZilla is software that uses FTP (File Transfer Protocol).

It allows you to make the connection between your PC and host server.

FileZilla is free (freeware).

You can download it by clicking here and going to "My Tools".


To put your website online, you need to transfer files to your host server using FTP (File Transfer Protocol). If you opt for 1-click modules, this step will not be necessary.


An IP represents your server's physical address.

Your domain name will point to your host server's IP in order to display your website, for example.

Another example: your domain must use a mail server to display your emails. The mail server's name will also point to an IP address.


This is a feature associated with shared hosting.

Multi-domain makes it possible to point multiple domain names to a single host server.

The end-client connects to a domain name and doesn't see that the server hosts various other sites.

NIC handle

The NIC handle is your customer reference. It is made up of two letters, some numbers and ends in -ovh (e.g. xx9999-ovh).

This type of reference is originally used by registers.


PHP for Hypertext Preprocessor (recursive acronym) is a programming language used to develop dynamic websites. It is used in the majority of CMS.

Some sites need a specific version of the PHP installed on the server in order to operate. That is why you can modify it on shared hosts.


PhpMyAdmin(PMA) is the software you can use to log in to an SQL database.


A sub-domain allows you to create names that derive from and compliment your original domain name (for example, to quickly access a section of the site).


www is the sub-domain. OVH is the domain. com is the domain extension.

The "www" sub-domain is automatically created.

If you want to develop an application in development mode, you can create the sub-domain:, for example.


SSH is another data transfer protocol, like FTP protocol.

This protocol typically executed from the command line via a terminal such as Putty.


Secured Sockets Layer is the name of the most well-known, secure protocol on the internet.

We use this protocol to connect to webmail and/or via a mail client, as well as for your shared host server's certificate.


The URL corresponds to your domain name's web address. For example, if your whole site is stored in a folder named "Boutique", your URL will be like this:


Whois is a command/tool that allows you to retrieve information on a domain name. In particular, you can retrieve the DNS servers used by the domain name, information about the domain owner if this information is not hidden, and generic information such as the domain name's creation or expiration date.
