Scripting language in the context of "AWK"

Hypertext Markup Language (HTML) is the standard markup language for documents designed to be displayed in a web browser. It defines the content and structure of web content. It is often assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript.

Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for its appearance.

A guestbook (also guest book, visitor log, visitors' book, visitors' album) is a paper or electronic means for a visitor to acknowledge a visit to a site, physical or web-based, and leave details such as their name, postal or electronic address and any comments. Such paper-based ledgers or books are traditional in churches, at weddings, funerals, B&Bs, museums, schools, institutions and other private facilities open to the public. Some private homes keep visitors' books. Specialised forms of guestbooks include hotel registers, wherein guests are required to provide their contact information, and Books of Condolence, which are used at funeral homes and more generally after notable public deaths, such as the death of a monarch or president, or after a public disaster, such as an airplane crash.

On the web, a guestbook is a logging system that allows visitors of a website to leave a public comment. It is possible in some guestbooks for visitors to express their thoughts about the website or its subject. Generally, they do not require the poster to create a user account, as it is an informal method of dropping off a quick message. The purpose of a website guestbook is to display the kind of visitors the site gets, including the part of the world they reside in, and gain feedback from them. This allows the website owner to assess and improve their site. A guestbook is generally a script, which is usually remotely hosted and written in a language such as Perl, PHP, Python or ASP. Many free guestbook hosts and scripts exist.

In computing, a command is a high-level instruction received via an external interface that directs the behavior of a computer program. Commonly, commands are sent to a program via a command-line interface, a script, a network protocol, or as an event triggered in a graphical user interface.

Many commands support arguments to specify input and to modify default behavior. Terminology and syntax varies but there are notable common approaches. Typically, an option or a flag is a name (without whitespace) with a prefix such as dash or slash that modifies default behavior. An option might have a required value that follows it. Typically, flag refers to an option that does not have a following value. A parameter is an argument that specifies input to the command and its meaning is based on its position in the command line relative to other parameters; generally ignoring options. A parameter can specify anything, but often it specifies a file by name or path.

Scalable Vector Graphics (SVG) is an XML-based vector graphics format for defining two-dimensional graphics, having support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium since 1999.

SVG images are defined in a vector graphics format and stored in XML text files. SVG images can thus be scaled in size without loss of quality, and SVG files can be searched, indexed, scripted, and compressed. The XML text files can be created and edited with text editors or vector graphics editors, and are rendered by most web browsers. SVG can include JavaScript, potentially leading to cross-site scripting.

Perl is a high-level, general-purpose, interpreted, dynamic programming language. Though Perl is not officially an acronym, there are various backronyms in use, including "Practical Extraction and Reporting Language".

Perl was developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions. Perl originally was not capitalized and the name was changed to being capitalized by the time Perl 4 was released. The latest release is Perl 5, first released in 1994. From 2000 to October 2019 a sixth version of Perl was in development; the sixth version's name was changed to Raku. Both languages continue to be developed independently by different development teams which liberally borrow ideas from each other.

phpBB is an Internet forum package written in the PHP scripting language. The name "phpBB" is an abbreviation of PHP Bulletin Board. Available under the GNU General Public License, phpBB is free and open-source.

Features of phpBB include support for multiple database engines (MariaDB, Microsoft SQL Server, MySQL, PostgreSQL, SQLite, Oracle Database), flat message structure (as opposed to threaded), hierarchical subforums, topic split/merge/lock, user groups, multiple attachments per post, full-text search, plugins and various notification options (e-mail, Jabber instant messaging, ATOM feeds).

Netscape Communications Corporation (originally Mosaic Communications Corporation) was an American independent computer services company with headquarters in Mountain View, California, and then Dulles, Virginia. Its Netscape web browser was once dominant but lost to Internet Explorer and other competitors in the first browser war, with its market share falling from more than 90 percent in the mid-1990s to less than one percent in 2006. An early Netscape employee, Brendan Eich, created the JavaScript programming language, the most widely used language for client-side scripting of web pages. A founding engineer of Netscape, Lou Montulli, created HTTP cookies. The company also developed SSL which was used for securing online communications and was later renamed to TLS.

Netscape stock traded from 1995 until 1999 when the company was acquired by AOL in a pooling-of-interests transaction ultimately worth US$10 billion. In February 1998, approximately one year before its acquisition by AOL, Netscape released the source code for its browser and created the Mozilla Organization to coordinate future development of its product. The Mozilla Organization rewrote the entire browser's source code based on the Gecko rendering engine, and all future Netscape releases were based on this rewritten code. When AOL scaled back its involvement with Mozilla Organization in the early 2000s, the Organization proceeded to establish the Mozilla Foundation in July 2003 to ensure its continued independence with financial and other assistance from AOL. The Gecko engine is used to power the Mozilla Foundation's Firefox browser.

A content delivery network (CDN) or content distribution network is a geographically distributed network of proxy servers and corresponding data centers. CDNs provide high availability and performance ("speed") through geographical distribution relative to end users, and arose in the late 1990s to alleviate the performance bottlenecks of the Internet as it was becoming a critical medium. Since then, CDNs have grown to serve a large portion of Internet content, including text, graphics and scripts, downloadable objects (media files, software, and documents), applications (e-commerce, portals), live streaming media, on-demand streaming media, and social media services.

CDNs are a layer in the internet ecosystem. Content owners such as media companies and e-commerce vendors pay CDN operators to deliver their content to their end users. In turn, a CDN pays Internet service providers (ISPs), carriers, and network operators for hosting its servers in their data centers.
