3. ICQ • It refers to an instant messaging service that serves the purpose of receiving updates from one’s server. Such notifications can be configured in the “Contact Manager” interface in cPanel, by clicking on WHM -> Home -> Server Contacts -> Contact Manager. • With regard to servers, let us briefly touch upon web hosting, where server space is leased by web hosting companies to store the files of websites. These companies also provide the services and the technology that are required by websites to be accessible online. Certain terms are frequently used to refer to web hosting service providers, such as, the “Best Website Hosting Company” or the “Best Cloud Hosting Company” or even the “Best Windows Hosting Company in India”

4. Identity Provider • It indicates third-party authority that is meant to provide external authentication to other services as well as sites to log in. External Authentication modules can be used by third-party developers. External Authentication can be configured in the “Manage External Authentications” interface in WHM. The path to do so is, WHM -> Home -> Security Center -> Manage External Authentications.

5. Include (file) • It refers to that file which is added automatically within another file, by a program. Custom content can be added by such files to the header or footer of the cPanel interface. •  Include command can be used by the server administrators in order to add specifications to the file that relates to Apache configuration. Alternatively, the “Apache Configuration” interface in WHM can be used by clicking on, WHM -> Home -> Service Configuration -> Apache Configuration.

6. Index Page • It refers to the default page that is viewed by the visitors upon accessing a website directory. This default page is usually, index.html or index.htm or index.php. • In the event that no index page is available for a specific directory, the visitor is shown a list of files in that directory. This happens unless indexing is disabled in the “Indexes” interface in cPanel. It can be done by clicking on cPanel -> Home -> Advanced -> Indexes.

7. Internet Message Access Protocol (IMAP) It refers to one of the 2 most extensively used methods for email transfer. Email account information is synchronized regularly with the mail server by IMAP. When multiple devices are used by a user to check emails, it is IMAP that lets the user know the messages that have been viewed by him and replied to and/or forwarded.

8. 1-800-123 -8156 Whoa! That’s a big number, aren’t you proud?

9. Internet Protocol (IP) It indicates the main protocol that transmits information across the Internet. IP addresses are used by this protocol to serve the purpose of delivering information from one host to another.  2 versions of Internet Protocol are supported by cPanel & WHM. One of those is IPv4 which is an older but more popular and accessible version. It uses 32-bit IP addresses. The availability of this version is limited. The other one is IPv6 which is a newer version. It uses 128-bit IP addresses. A vast number of addresses are available in this version. An IPv6-enabled network and server are needed by it.

10. Internet Protocol (IP) Address It refers to a certain identification number for a computer on a network. This enables other computers to find it and then initiate communication with it. “Add a New IP Address” interface in WHM can be used to add new IP addresses to a user’s existing pool of IP addresses. It can be done by clicking on, WHM -> Home -> IP Functions -> Add a New IP Address.

11. Internet Relay Chat (IRC) It is an application layer protocol that has to do with real-time online communication. It ensures that group discussions as well as one-to-one messaging can take place, along with data transfer. Custom modules can be created by third-party developers in order to send notifications that are meant for IRC and other services.

12. iptables It refers to a user space utility program. It enables the configuration of Linux kernel firewall data tables. This configuration is done by server administrators.

13. Jailed Shell It is a Common Line Interface (CLI) configuration that is meant to restrict a user’s access rights. Shell sessions are limited by the system to a filesystem which doesn’t have the home directories of the other users of cPanel who are on the system. VirtFS is used by cPanel & WHM to provide jailshell access. Custom jailed shell mounts can be created to let users have additional access.

14. Java It is a computer programming language that is used by many web applications.

15. JavaScript Object Notation (JSON) It refers to a file format in which human-readable text is used to store as well as exchange data. It has data objects in array data types and in attribute-value pairs. JSON is used by cpanel & WHM for API output and for some data storage that is internal. Many basic variables can be used for the sorting of API output in JSON.

16. Kernel It is the central component of the operating system of a server. The kernel serves the purpose of managing communications between the user and the resources of a server (processor, memory etc.).

17. Key Keys are meant for the purpose of encrypting or decrypting information. Keys have an important function in ensuring security. Hence, these need to be guarded properly.

18. Known Netblock It is a class C address space. It has an address that has been used by a user to log in successfully. The settings for known netblocks can be configured in the “Greylisting” interface in WHM, by clicking on WHM -> Home -> Email -> Greylisting.
