A web server is a computer that stores websites on the Internet and delivers web pages to viewers upon request. This service is referred to as web hosting. Every web server has a unique address, called an Internet Protocol address, that tells other computers connected to the Internet where to find the server on the vast network. The Internet Protocol (IP) address looks something like this: 69.93.141.146; this address links to a more human-friendly address, such as http://www.ieinternet.com/ Web hosts rent out space on their web servers for people or businesses to set up their own websites, and the web server allocates a unique website address to each website it hosts.

Every computer connected to the Internet must have a unique address known as an IP (Internet Protocol) address. The IP address is a numeric address written as a set of four numbers separated by dots, for example 64.149.219.213. The address provides a unique identification of a computer and the network it belongs to.

(What we do) Hosting (also known as Web site hosting and Web hosting) is the business of housing, serving, and maintaining files for one or more Web sites. More important than the computer space that is provided for Web site files is the fast connection to the Internet. Using a hosting service lets many companies share the cost of a fast Internet connection for serving files.

Domain Name System - a system of mapping names to IP addresses. Because domain names are alphabetic, they're easier for humans to remember. The Internet, however, is really based on IP addresses. Every time you use a domain name, DNS translates the name into the corresponding IP address. It is similar to a phonebook for the Internet.

Post Office Protocol is the most common protocol used to retrieve e-mail from a mail server. Most e-mail applications (sometimes called an e-mail client) use the POP protocol, although some can use the newer IMAP (Internet Message Access Protocol). The newest version, POP3, can be used with or without SMTP (an e-mail sending protocol, stands for Simple Mail Transfer Protocol). IMAP servers are similar to POP servers, the only difference being they save the e-mail so they can be retrieved from multiple locations or multiple users.

'''What is Bandwidth?'''
 
−
 
 
−
Bandwidth in respect to hosting, is the amount of information that can be transferred from the server to a Browser. Hosts usually limit the amount of bandwidth a user has available per month. As an example, if you had a file on your site that was 1mb and you had 1Gb of bandwidth, users could download the file 1000 total times.
 
−
 
 
−
'''What is Disk Space?'''
 
−
 
 
−
Disk Space - the total physical amount of hard drive space a host allows a user to have.
 
−
 
 
−
'''What is a Dedicated Server?'''
 
−
 
 
−
A Dedicated Server is one that only has a single website running on it. Rather than a shared server which has multiple websites being served up.
 
−
 
 
−
'''What is a CGI Service'''
 
−
 
 
−
CGI stands for Common Gateway Interface. CGI provides a method to interface a computer program with an HTML page. CGI programs can be written to do many different things, which includes: counting visitors to your web site; processing data obtained from online forms; and creating simple animations.
 
−
 
 
−
'''What is a dashboard?'''
 
−
 
 
−
In information technology, a dashboard is a user interface that, somewhat resembling an automobile's dashboard, organizes and presents information in a way that is easy to read.
 
−
 
 
−
'''What is IMAP4?'''
 
−
 
 
−
IMAP stands for Internet Message Access Protocol. It, like POP, is a way of accessing your email on our servers. The primary advantage to IMAP is that since it maintains the original emails on the server, no matter how many different machines you login from you will have complete access to all your email. It also let’s you work with an unlimited number of server-side folders, which makes IMAP a perfect companion to server-side email filtering and Spam administration
 
−
 
 
−
'''What is encrypted mail?'''
 
−
 
 
−
Email encryption refers to encryption, and often authentication, of email messages, which can be done in order to protect the content from being read by unintended recipients.
 
−
 
 
−
'''What is FTP?'''
 
−
 
 
−
File Transfer Protocol - Allows the transfer of one or more files from one computer to another across the Internet. Usually from a personal computer to a Server or vice versa.
 
−
 
 
−
'''What is meant by the term “cached”?'''
 
−
 
 
−
In computer terms a cache is a type of temporary storage. Your computer's cache stores information about whatever program you're running. Cache memory usually runs at a higher speed than a hard disk so that this information can be accessed quickly.
 
−
 
 
−
'''What is a DNS cache?'''
 
−
 
 
−
A DNS cache contains entries that translate Internet domain names such as "ieinternet.com" to IP addresses. The Internet's Domain Name System (DNS) involves caching on both Internet DNS servers and on the client computers that contact DNS servers. These caches provide an efficient way for DNS to efficiently keep the Internet synchronized as the IP addresses of some servers change and as new servers come online.
 
−
 
 
−
'''What is a sub-directory?'''
 
−
 
 
−
A directory that is located within another directory. A similar term can be used to describe a folder beneath another folder in a graphical user interface (GUI).
 
−
 
 
−
'''What is mkdir command?'''
 
−
 
 
−
The mkdir command is is used to create new directories
 
−
 
 
−
'''What is Binary or ASCII?'''
 
−
 
 
−
An ASCII file is a binary file that stores ASCII codes. Recall that an ASCII code is a 7-bit code stored in a byte. To be more specific, there are 128 different ASCII codes, which means that only 7 bits are needed to represent an ASCII character.
 
−
 
 
−
However, since the minimum workable size is 1 byte, those 7 bits are the low 7 bits of any byte. The most significant bit is 0. That means, in any ASCII file, you're wasting 1/8 of the bits. In particular, the most significant bit of each byte is not being used.
 
−
 
 
−
Although ASCII files are binary files, some people treat them as different kinds of files. I like to think of ASCII files as special kinds of binary files. They're binary files where each byte is written in ASCII code.
 
−
 
 
−
A full, general binary file has no such restrictions. Any of the 256 bit patterns can be used in any byte of a binary file.
 
−
 
 
−
We work with binary files all the time. Executables, object files, image files, sound files, and many file formats are binary files. What makes them binary is merely the fact that each byte of a binary file can be one of 256 bit patterns. They're not restricted to the ASCII codes.
 
−
 
 
−
'''What is phpBB?'''
 
−
 
 
−
phpBB is a free flat-forum bulletin board software solution that can be used to stay in touch with a group of people or can power your entire website
 
−
 
 
−
'''What is Mail manager?'''
 
−

'''Who are the IEDR?'''
 
−
 
 
−
The IEDR's originated in UCD but since July 2000 it has been a private company, limited by guarantee. It has no shareholders, the company is owned by its members who are the directors. Surpluses are not distributed, they are added to opening reserves. Directors as per the company's constitution do not have a “beneficial interest“ in the reserves of the company. Only the IEDR can administer .ie - which it does as a public service - but it is not a monopoly in the sense that anybody in Ireland, or elsewhere, can register domains from a choice of approximately 250 different national and generic TLD names. The IEDR liaises as required with national and international governments, governing bodies, trade associations and abides by Internet best practice principles while still operating as an independent private company.

−
 
 
−
'''What is VPS = virtual private server?'''
 
−
 
 
−
Virtual private server (VPS) is a term used by Internet hosting services to refer to a virtual machine. The term is used for emphasizing that the virtual machine, although running in software on the same physical computer as other customers' virtual machines, is functionally equivalent to a separate physical computer, is dedicated to the individual customer's needs, has the privacy of a separate physical computer, and can be configured to run as a server computer (i.e. to run server software).
 
−
 
 
−
'''What is Apache web server?'''
 
−
 
 
−
Apache, otherwise known as Apache HTTP Server, is an established standard in the online distribution of website services, which gave the initial boost for the expansion of the World Wide Web. It is an open-source web server platform, which guarantees the online availability of the majority of the websites active today. The server is aimed at serving a great deal of widely popular modern web platforms/operating systems such as Unix, Windows, Linux, Solaris, Novell NetWare, FreeBSD, Mac OS X, Microsoft Windows, OS/2, etc.

−
'''What is MySQL?'''
 
−
 
 
−
MySQL is a database system used on the web. Basically, a MySQL database allows you to create a relational database structure on a web-server somewhere in order to store data or automate procedures. If you think of it in comparison to Microsoft Access, MySQL is what holds all of your tables, PHP acts as your queries (among other things), and your forms are basically web pages with fields in them. With all of this combined, you can create truly spectacular projects on the web.
 
−
 
 
−
'''What is TCP/IP?'''
 
−
 
 
−
TCP/IP stands for the 'Transport Control Protocol / Internet Protocol' suite. TCP/IP was created in 1983 to replace NCP. The advantage of TCP/IP is it's versitility. It can successfully switch packets of all shapes and sizes, and work across a varieties of networks.
 
−
 
 
−
TCP/IP has become the backbone of the Internet and its composite LANs and WANs. As already stated, it is due to it's ability to switch packets from any computer systems, regardless of network peculiarities, operating system differences and other packet differences.
 
−
 
 
−
The TCP/IP protocol suite refers to several separate protocols that computers use to transfer data across the Internet. Listed below are four of the most commonly used TCP/IP protocols,
 
−
 
 
−
'''What is NAT?'''
 
−
 
 
−
Network Address Translation (NAT) is the process where a network device, usually a firewall, assigns a public address to a computer (or group of computers) inside a private network. The main use of NAT is to limit the number of public IP addresses an organization or company must use, for both economy and security purposes.
 
−
 
 
−
'''What is Web filtering?'''
 
−
 
 
−

'''What is HTML?'''
 
−
 
 
−
HTML (HyperText Markup Language) is a language to specify the structure of documents for retrieval across the Internet using browser programs of the WorldWideWeb.
 
−
 
 
−
HTML is an application of the Standard Generalized Markup Language (SGML) which is the International Standard (ISO 8879) for text markup. The principle is that text markup concentrates on structure rather than appearance, making the files more reuseable and leaving the visual details to the end-user software (like the browser you're reading this with now)
 
−
 
 
−
'''What is Joomla?'''
 
−
 
 
−
Joomla is a free and open source content management system (CMS) for publishing content on the World Wide Web and intranets and a model–view–controller (MVC) Web application framework that can also be used independently.
 
−
 
 
−
Joomla is written in PHP, uses object-oriented programming (OOP) techniques (since version 1.6[2]) and software design patterns, stores data in a MySQL (or, since version 2.5, MS SQL) database, and includes features such as page caching, RSS feeds, printable versions of pages, news flashes, blogs, polls, search, and support for language
 
−
 
 
−
'''What is Dreamweaver?'''

Adobe Dreamweaver is a site building and publishing tool appropriate for intermediate to advanced users that allows you to create and edit web pages and applications using a graphical interface and built-in advanced design and coding features.
 
−
 
 
−
'''What is CSS?'''
 
−
 
 
−
Cascading Style Sheets (CSS) is a style sheet language used to describe the presentation semantics (the look and formatting) of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTML, but the language can also be applied to any kind of XML document, including plain XML, SVG and XUL.
 
−
 
 
−
CSS is designed primarily to enable the separation of document content (written in HTML or a similar markup language) from document presentation, including elements such as the layout, colors, and fonts
 
−
 
 
−
'''What is Perl?'''
 
−
 
 
−
Perl is a programming language which can be used for a large variety of tasks. A typical simple use of Perl would be for extracting information from a text file and printing out a report or for converting a text file into another form. But Perl provides a large number of tools for quite complicated problems, including systems programming.
 
−
 
 
−
Programs written in Perl are called Perl scripts, whereas the term the perl program refers to the system program named perl for executing Perl scripts.
 
−
