Blog

A blog, or weblog, is an online journal, diary, or serial published by a person or group of people.

Blogs are typically used by individuals or peer groups, but are occasionally used by companies or organizations as well. In the corporate arena, the only adopters of the blog format so far have tended to be design firms, web media companies, and other "bleeding edge" tech firms.

Blogs often contain public as well as private content. Depending on the functionality of the CMS software that is used, some authors may restrict access — through the use of accounts or passwords — to content that is too personal to be published publicly.

Blogging

Blogging is the act of writing in one's blog. To blog something is to write about something in one's blog. This sometimes involves linking to something the author finds interesting on the internet.

See also: blogosphere, blogroll

Blogosphere

The blogosphere is the subset of internet web sites which are, or relate to, blogs.

See also: blog, blogroll

Blogroll

A blogroll is a list of links to various blogs or news sites. Often a blogroll is "rolled" by a service which tracks updates (using feeds) to each site in the list, and provides the list in a form which aggregates update information.

Bookmarklet

A bookmarklet (or favelet) is a "faux" bookmark containing scripting code, usually written in JavaScript, that allows the user to perform a function.

Examples

  • The WordPress Press It bookmarklet allows a user to quickly blog whichever web site he/she is currently viewing.
  • The del.icio.us bookmarklets allow a user to quickly post a link to his/her del.icio.us bookmarks list.
  • the Flickr bookmarklet allows a user to view all images on the page he/she is currently viewing, then select one or more to post to his/her Flickr photostream.
  • Tantek's favelets

Boolean

A Variable or expression which evaluates to either true or false.

Category

Each post in WordPress is filed under a category. Thoughtful categorization allows posts to be grouped with others of similar content and aids in the navigation of a site. Please note, the post category should not be confused with the Link Categories used to classify and manage Links.

CGI

CGI (Common Gateway Interface) is a specification for server-side communication scripts designed to transfer information between a Web server and a web-client (browser). Typically, HTML pages that collect data via forms use CGI programming to process the form data once that data is submitted by the client.

Character Entity

A character entity is a method used to display special characters normally reserved for use in HTML. For example, the less than (<) and greater than (>) are used as part the HTML tag structure, so both symbols are reserved for that use. But, if you need to display those symbols on your site, you can use character entities. For example:

use &lt;  for the less than (<) symbol
use &gt;  for the greater than (>) symbol

Related articles: Fun Character Entities

Character set

A character set is a collection of symbols (letters, numbers, punctuation, and special characters), when used together, represent meaningful words in a language. Computers use an encoding scheme so members of a character set are stored with a numeric value (e.g. 0=A, 1=B, 2=C, 3=D). In addition, a collation determines the order (i.e alphabetic) to use when sorting the character set. By default, WordPress uses the Unicode UTF-8 (utf8) character set for the WordPress MySQL database tables created during the installation process. Beginning with Version 2.2, the database character set (and collation) is defined in the wp-config.php file. Also note, the character set used for syndication feeds is set in the Administration > Options > Reading panel.

chmod

chmod is a Unix/Linux shell command used to change permissions on files. Its name is a contraction of "change mode."

Related articles: Changing File Permissions, UNIX Shell Skills, .htaccess for subdirectories

Class

Classes are groupings of CSS styles which can be applied to any HTML element.

Related articles: CSS, Blog Design and Layout

Collation

Collation refers to the order used to sort the letters, numbers, and symbols of a given character set. For example, because WordPress, by default, uses the UTF-8 (utf8) character set, and when the WordPress MySQL database tables are created during the installation process, MySQL assigns utf8_general_ci collation to those table. Beginning with Version 2.2, the collation (and character set) used by WordPress is defined via the wp-config.php file.

Comments

Comments are a feature of blogs which allow readers to respond to posts. Typically readers simply provide their own thoughts regarding the content of the post, but users may also provide links to other resources, generate discussion, or simply compliment the author for a well-written post.

Comments can be controlled and regulated through the use of filters for language and content, and often times can be queued for approval before they are visible on the web site. This is useful in dealing with comment spam.

Content

Content consists of text, images, or other information shared in posts. This is separate from the structural design of a web site, which provides a framework into which the content is inserted, and the presentation of a site, which involves graphic design. A Content Management System changes and updates content, rather than the structural or graphic design of a web site.

Content Management System

A Content Management System, or CMS, is software for facilitating the maintenance of content, but not design, on a web site. A blogging tool is an example of a Content Management System.

E

Excerpt

An excerpt is a condensed description of your blog post and refers to the summary entered in the Excerpt field of the Write Post SubPanel (see Advanced Editing). The excerpt is used to describe your post in RSS feeds and is typically used in displaying search results. The excerpt is sometimes used in displaying the Archives and Category views of your posts. The Template Tag the_excerpt() can be used to access the contents of this field.

An excerpt should not be confused with the teaser which refers to the first few sentences or paragraphs of a post. When typing a long post you can insert the <!--more--> Quicktag after a few sentences to act as a cut-off point. When the post is displayed, the teaser, followed by a hyperlink (such as Read the rest of this entry...), are displayed. Your visitor can then click on that link to see the full version of your post. The Template Tag the_content() can be used to display the teaser.

Feed

A feed is a function of special software that allows "Feedreaders" to access a site automatically looking for new content and then posting the information about new content and updates to another site. This provides a way for users to keep up with the latest and hottest information posted on different blogging sites. Some Feeds include RSS (alternately defined as "Rich Site Summary" or "Really Simple Syndication"), Atom or RDF files. Dave Shea, author of the web design weblog Mezzoblue has written a comprehensive summary of feeds. Feeds generally are based on XML technology.

FTP

FTP, or File Transfer Protocol, is rather predictably, a client-server protocol for transferring files. It is one way to download files, and the most common way to upload files to a server.

An FTP client is a program which can download files from, or upload files to, an FTP server.

You may need to use an FTP client to upload your WordPress files to your web server, particularly if you use a hosting provider.

Hack

A hack is a bit of code written to customize or extend the functionality of a software product. Older versions of WordPress used a hack-based extension system, but versions 1.2 and above of WordPress use a plugin API with hooks for extensions.

Hacking

Hacking is the process of writing code for, or contributing code to, a piece of software.

There is some controversy surrounding the meaning of this term. It began as a benign term meaning "to exercise proficiency" or "to alter or improve," but the popular media have since construed it to mean "to break into a computer system, usually with malicious intent." Many in the computer industry have recently begun trying to 'take back' the word from its popular mutation, and many have adopted the term cracking to replace the malicious interpretation. Because of the desire to reclaim the word, you will often find the term used in conjunction with open source projects, intended in its benign form. For more information about the history of the term, please see Wikipedia's article on Hacker.

Hosting provider

A hosting provider is a company or organization which provides, usually for a fee, infrastructure for making information accessible via the web. This involves the use of a web server (including web server software such as Apache), and may involve one or more related technologies, such as FTP, PHP, MySQL, and operating system software such as Linux or Unix.

Related articles: Hosting WordPress

.htaccess

A .htaccess file is a granular configuration file for the Apache web server software, used to set or alter the server's configuration settings for the directory in which it is present, and/or its child directories.

WordPress uses an .htaccess file in conjunction with the mod_rewrite Apache module to produce permalinks.

Note that .htaccess is a hidden file in Unix/Linux (as dictated by the preceding period '.'), meaning it may not be visible using the default settings of some FTP clients.

HTML

HTML, or Hypertext Markup Language, is the W3C standard language with which all web pages are built. It is the predecessor to XHTML, but HTML is often still used to describe either one. It is often used in conjunction with CSS and/or JavaScript.

WordPress strives to conform to the XHTML standard.

IP address

An IP address is a unique number (e.g. 70.84.29.148) assigned to a computer (or other internet-capable information appliance, such as a network printer) to enable it to communicate with other devices using the Internet Protocol. It is a computer's identity on the internet, and every computer connected to the internet is assigned at least one — although the methods of assigning these addresses, and the permanence and duration of their assignment, differ according to the use of the computer and the circumstances of its internet use.

Every web server is assigned an IP address as well, but often times hosting providers will assign multiple IP addresses to one computer, in the event that multiple web sites reside on the same physical server. This is the case with most inexpensive 'managed' or 'group' hosting packages.

Domain names were created to provide an easier means of accessing internet resources than IP addresses, which are cumbersome to type and difficult to remember. Every domain name has at least one corresponding IP address, but only a small number of IP addresses have a domain name associated with them, since only computers that are web servers require domain names. The Domain Name System (DNS) is what maps Domain names to IP addresses.

JavaScript

Developed by Netscape and Sun, JavaScript is a client-side programming or scripting language. It's used to create interactive and dymanic effects on a web page, as well as handle and manipulate form data. JavaScript is a separate language from Java. All modern browsers support JavaScript. Some excellent JavaScript references and tutorials can be found at JavaScript Kit.

Mac OS X

Mac OS X is an operating system specifically for modern Macintosh computers. The operating system was first commercially released in 2001. It consists of two main parts: Darwin, an open source Unix-like environment which is based on the BSD source tree and the Mach microkernel, adapted and further developed by Apple Computer with involvement from independent developers; and a proprietary GUI named Aqua, developed by Apple.

Meta

Meta has a number of meanings, but generally means information about. In WordPress, meta usually refers to administrative type information. As described in en:Meta Tags in WordPress, meta is the HTML tag used to describe and define a web page to the outside world (search engines). In the article Post Meta Data, meta refers to information associated with each post, such as the author's name and the date posted. Meta Rules define the general protocol to following in using the Codex. Also, many WordPress based sites offer a Meta section, usually found in the sidebar, with links to login or register at that site. Finally, Meta is a MediaWiki namespace that refers to administrative functions within Codex.

Moblogging

Moblogging is the act of posting to one's blog via a mobile device, e.g. mobile phone, smartphone, or Blackberry. It is pronounced as mōbə-logging or mōb-logging, or sometimes as mŏb-logging in reference to smart mobs.

mod_rewrite

mod_rewrite is an extension module of the Apache web server software which allows for "rewriting" of URLs on-the-fly. Rewrite rules use regular expressions to parse the requested URL from the client, and translate it into a different URL before interpretation.

WordPress uses mod_rewrite for its permalink structure, which is optional functionality.

MySQL

MySQL is a popular open source SQL (Structured Query Language) database implementation, available for many platforms, including Windows, Unix/Linux and Mac OS X.

WordPress requires a MySQL database to store all blog information, including posts, comments, metadata, and other information.

News reader

A news aggregator or news reader is a computer program which tracks syndicated information feeds, via RSS, RDF, or Atom. Most news aggregators allow one to 'subscribe' to a feed, and automatically keep track of the articles one has read, similar to an email client tracking read emails.

Many blogs make their content available in feed form for the convenience of readers using news aggregators. WordPress can generate feeds in RSS and/or Atom formats.

P

Page

A Page is often used to present "static" information about yourself or your site. A good example of a Page is information you would place on an About Page. A Page should not be confused with the time-oriented objects called posts. Pages are typically "timeless" in nature and live "outside" your blog.

The word "page" has long been used to describe any HTML document on the web. In WordPress, however, "Page" refers to a very specific feature first introduced in WordPress version 1.5.

Related articles: Pages, Write Page SubPanel

Perl

Perl is an acronym for Practical Extraction and Report Language, but it's most commonly spelled as a proper name. It's a very popular and powerful scripting language used for web applications, although its use is being largely replaced by PHP in the mainstream. One of its strengths lies in its speedy and effective use of regular expressions. Its unofficial motto is, "There's More Than One Way To Do It," or "TMTOWTDI," owing to the extreme flexibility of the syntax.

WordPress does not use Perl, and it is therefore not required.

Permalink

A permalink is a URL at which a resource or article will be permanently stored. Many pages driven by Content Management Systems contain excerpts of content which is frequently rotated, making linking to bits of information within them a game of chance. Permalinks allow users to bookmark full articles at a URL they know will never change, and will always present the same content.

Permalinks are optional in WordPress, but are highly recommended as they greatly increase the cleanliness of URL. WordPress uses the Apache module mod_rewrite to implement its permalink system.

Permissions

Permissions are security settings restricting or allowing users to perform certain functions. In the case of files on Unix or Linux systems, there are three types of permissions: read, write, and execute. In the case of MySQL databases, there are many more: SELECT, INSERT, UPDATE, DELETE, etc. — although MySQL refers to them as privileges.

Related articles: Changing File Permissions

PHP

PHP is a recursive acronym for PHP: Hypertext Preprocessor. It is a popular server-side scripting language designed specifically for integration with HTML, and is used (often in conjunction with MySQL) in Content Management Systems and other web applications. It is available on many platforms, including Windows, Unix/Linux and Mac OS X, and is open source software.

WordPress is written using PHP and requires it for operation.

Ping

Within the WordPress interface, "ping" is sometimes used to refer to Pingbacks and Trackbacks.

In general computer terms, "ping" is a common utility used in a TCP/IP environment to determine if a given IP Address exists or is reachable. Typically, Ping is used to diagnose a network connection problem. Many times you will be asked, "Can you ping that address?". That means, does the Ping utility return a success message trying to reach the "problem" IP Address?

External links: Ping at Wikipedia

PingBack

Pingback lets you notify the author of an article if you link to his article (article on a blog, of course). If the links you include in an article you write on a blog lead to a blog which is pingback-enabled, then the author of that blog gets a notification in the form of a pingback that you linked to his article.

If you're feeling really geeky you may want to check out the Pingback technical specification.

Plugin

A Plugin is a group of php functions that can extend the functionality present in a standard WordPress weblog. These functions may all be defined in one php file, or maybe spread among more than one file. Usually, a plugin is a php file that can be uploaded to the "wp-content/plugins" directory on your webserver, where you have installed WordPress. Once you have uploaded the plugin file, you should be able to "turn it on" or Enable it from the "Plugins" page in the administration interface of your weblog. The WordPress source code contains hooks that can be used by plugins.

Port

Within the context of the WordPress community, a port is a bit of code that has been rewritten to be compatible with WordPress. For example, if someone wrote a plugin for MoveableType, WordPress users may want to find a port of that plugin for WordPress. Port can also be used as a verb: to rewrite a piece of software for a different platform/language.

Q

Query string

A sequence of codes in a Uniform Resource Identifier (URI) that a web page uses to determine what dynamic data to display. The query string in a URI comes after an initial question mark, and may contain several parameters separated by ampersands. WordPress uses query strings to indicate criteria to search for specific posts or sets of posts in the database. The use of query strings is generally believed to impede the indexing of dynamic pages by search engines. For this reason, it is often desirable to use a method such as mod_rewrite to reduce exposure of query strings to search engines and other site visitors.

Query Variable

A Variable passed through the query string. For example, in the query string ?category_name=tech&feed=atom, there are two query variables: category_name with a value of 'tech', and feed with a value of 'atom'.

Back to the Top

R

RDF

Resource Description Framework. A language used to describe the locations of resources on the web. WordPress can produce output in RDF format that describes the locations of posts. Like RSS, RDF is used for content syndication.

Relative Path

A relative path is the location of a file in relation to the current working directory and does not begin with a slash (/). This is different than an absolute path which gives an exact location.

See also: Absolute Path

External links: Path_Computing at Wikipedia

Relative URI

A relative URI (sometimes called a relative link) is a partial URI that is interpreted (resolved) relative to a base URI.

On the World Wide Web, relative URIs come in two forms:

A relative URI with an absolute path is interpreted relative to the domain root:

 /images/icecream.jpg → http://domain.example/images/icecream.jpg

A relative URI with a relative path is interpreted relative to the URL of the current document. E.g., on the web page http://domain.example/icecream/chocolate.html,

 strawberry.html → http://domain.example/icecream/strawberry.html

Wikipedia: URI Resolution

Recordset

Recordset refers to the group of records or result returned from a database query.

See also MySQL, $wpdb database class

RSS

"Real Simple Syndication": a format for syndicating many types of content, including blog entries, torrent files, video clips on news-like sites. Programs called news aggregators permit users to view many feeds at once, providing 'push' content constantly. See Category:Feeds for Codex resources about bringing RSS feeds into WordPress. See also RDF Site Summary.


Robots.txt

Web Robots are programs that traverse the Web automatically. Some people call them Web Wanderers, Crawlers, or Spiders. Search Engines are the main Web Robots. Search Engines look for yourserver.com/robots.txt file to see what and where they should look for content and files on yourserver.com You can learn more about robots and robots.txt at The Web Robots Page

S

Shell

A shell is a program which interacts directly with an operating system such as MS-DOS, Unix/Linux, Mac OS X, or others — but it is most commonly associated with Unices. It is often referred to as a 'console' or 'command line', because it is controlled using typed commands rather than mouse or graphical interface input.

Most often, when interacting with a remote computer (as one would when configuring WordPress), an additional "faux" shell is involved called SSH.

Some popular shell programs are:

  • Bash (Bourne Again Shell)
  • Tcsh (an expanded C Shell)
  • Zsh

Singleton

Singletons are objects that exist globally and are the only one of their class; if one instance of a class is created per request, this instance is a singleton object. Some singletons that WordPress uses are $wp_query and $wp_rewrite, instances of the WP_Query and WP_Rewrite objects.

Slug

A slug is a few words that describe a post or a page. Slugs are usually a URL friendly version of the post title (which has been automatically generated by WordPress), but a slug can be anything you like. Slugs are meant to be used with permalinks as they help describe what the content at the URL is.

Example post permalink: http://wordpress.org/development/2006/06/wordpress-203/

The slug for that post is "wordpress-203".

Smileys

Smiley are stylized representations of a human face, usually displayed as yellow buttons with two dots for the eyes, and a half mouth. Smileys are often use in Wordpress Plugins. By default, WordPress automatically converts text smileys to graphic images. When you type ;-) in your post you see http://codex.wordpress.org/images/c/c0/icon_smile.gif when you preview or publish your post.

See also: Using_Smilies

Spam

Once upon a time, SPAM was an animal by-product that came in a can and was fodder for many Monty Python sketches, but since the world-wide adoption of the internet as an integral part of daily life, Spam has become synonymous with what is wrong with the internet. Spam, in general terms, is an email or other forms of unsolicited advertising. Spam is very easy to spread throughout the internet, and works on the principle that if you send out thousands, or hundreds of thousands of unsolicited advertisements, scams, or other questionable methods of making money, that you only need a very small percentage of people to be fooled and you will make lots of money.

Common spam these days comes from online gambling sites and those trying to sell drugs for "male enhancement." Lately, web logs, or blogs, as we call them, have been targeted by spammers to try to increase their site ratings in the search engines. Spammers use various methods to distribute their electronic junk mail, and employ bots, or computer programs to quickly and easily send email or comments to millions of addresses and IPs all over the world.

Spammers can be difficult to track down as they often hijack peoples' email and IP addresses. When this happens, it may appear a friend sent you the spam, but in fact, the spammer's bot grabbed your friend's email address and used it to hide the true source of the spam. WordPress developers and community members are constantly working on more and better ways to combat these annoying spammers as they clog the internet with their garbage. You can help by offering your talents, ideas, suggestions, or just by being vigilant and installing any of the currently-available spam combating tools.

SSH

SSH stands for Secure Shell. It is a communication protocol for connecting to remote computers over TCP/IP. Various authentication methods can be used which make SSH more secure than Telnet.

Subversion

Subversion is an open-source version control software tool used by the WordPress Developers to maintain and track the changes and updates to the various WordPress versions.

T

Tagline

A tagline is a catchy phrase that describes the character or the attributes of the blog in a brief, concise manner. Think of it as the slogan, or catchline for a weblog.

Telnet

Telnet is a communications protocol used to establish a connection to another computer. Telnet runs on top of TCP/IP and is typically used in conjuction with terminal emulation software to login to remote computers. Telnet is inherently insecure and has largely been replaced by SSH

Theme

A theme is a collection of files that work together to produce a graphical interface with an underlying unifying design for a weblog. A theme modifies the way the weblog is displayed, without modifying the underlying software. Essentially, the WordPress theme system is a way to skin your weblog.

Related articles: Theme Development, Using Themes

Trackback

Trackback helps you to notify another author that you wrote something related to what he had written on his blog, even if you don't have an explicit link to his article. This improves the chances of the other author sitting up and noticing that you gave him credit for something, or that you improved upon something he wrote, or something similar. With pingback and trackback, blogs are interconnected. Think of them as the equivalents of acknowledgements and references at the end of an academic paper, or a chapter in a textbook.

U

Unicode

A widely supported and preferred character encoding system.

For a computer to display letters (or any text characters), it needs to enumerate them - create an index of characters it knows how to display. These indexes are known as character sets. This is invaluable for users hosting WordPress in a non-English language.

The most widely used collections of these character sets are the iso-8859 with iso-8859-1 and iso-8859-15 (which contains the euro sign and some characters used in Dutch, French, Czech and Slovak) being the most common; they are also known as Latin1 and Latin9. These character sets use 8 bits (a single byte) for each character, allowing for 255 different characters (256, counting null). However, when considering that Latin-based languages aren't the only ones in the world (think Japanese or Hebrew), 255 characters aren't nearly enough.

There is a wide index of characters known as Unicode. Unicode has so many characters that sometimes more than 16 bits (2 bytes!) are required to represent them. Furthermore, the first 127 characters of Unicode are the same as the first 127 of the most widely used character set - iso-8859-1. For this purpose, UTF, the Unicode Translation Format, was created. UTF uses different numbers of bits for characters, and allows for the entire range of Unicode to be used. What you should probably know is:

  • UTF-8 is an 8-bit-minimum type of UTF. There are also UTF-16 and UTF-32.
  • If your document is in a Latin-based encoding, you probably don't need to change anything about it for it to be UTF.
  • A single UTF document can be in various languages with no need to switch encodings halfway through.

Unix

Unix, or UNIX, is a computer operating system developed at AT&T's Bell Laboratories starting back in 1969. Initially designed with the objective of creating an OS written in a high level language rather than assembly, a majority of web servers currently run on different "flavors" of this high-performance OS, or on Linux, developed as a Unix-like operating system.

URI and URL

Uniform Resource Identifier (Locator). A unique identifier for a document on the Internet. For instance, http://www.wikipedia.org/ is the URI for the Wikipedia.
In WordPress, these are as important as permalinks to your entries. A WordPress URI might appear as http://blog.example.com/2004/06/05/entry-name/.

Web server

A web server is a computer containing software for, and connected to infrastructure for, hosting, or serving, web sites written in HTML. The most common web server software on the internet is Apache, which is frequently used in conjunction with PHP, Perl, and other scripting languages.

It is possible to create one's own web server, hosted on any speed of internet connection, but many people choose to purchase packages from hosting providers, who have the capacity and facilities to provide adequate bandwidth, uptime, hardware, and maintenance for frequently-visited web sites.

XFN

The XHTML Friends Network. A decentralised project to have inter-blog links that represent relationships between bloggers. XFN links resemble <a href="http://www.photomatt.net/" rel="friend met">Photo Matt</a>.

XHTML

XHTML, or Extensible Hypertext Markup Language, is the successor to HTML as the W3C standard language with which all web pages are created. It is often used in conjunction with CSS and JavaScript.

WordPress strives to conform to the XHTML 1.0 Transitional standard.

XML

XML, or Extensible Markup Language, is written in Standard Generalized Markup Language (SGML) and essentially allows you to define your own markup language. XML is extremely useful in describing, sharing, and transmitting data across the Internet. Typically used in conjunction with HTML, XML defines data and HTML displays that data.

XML-RPC

XML-RPC is Extensible Markup Language-Remote Procedure Call. A Remote Procedure Call (RPC) allows you to a call (or request) another application and expect that application to honor the request (answer the call). So, XML-RPC allows a user (or developer) to send a request, formatted in XML, to an external application.

絶対パス

絶対パスフルパスとは、コンピュータやファイルシステム上にあるファイルやディレクトリのユニークな位置であり、通常、ルートディレクトリやドライブレターから始まります。パスの中のディレクトリやサブディレクトリは、通常はスラッシュ(/)で区切られます。

例: /Users/Matt/www/blog/images/icecream.jpg

あるページの絶対パスを知るには、まず、新しいテキストファイルに下記のテキストをコピーし、path.php というファイル名で保存。そして、このファイルをウェブブラウザで開きます(例えば、http://www.example.com/images/path.php)。

 <?php
 $p = getcwd();
 echo $p;
 ?>

テキストエディタ

A text editor is a program which edits files in plain text format, as compared to binary format. Using a non-text based word processing program (e.g. using Microsoft Word to edit PHP scripts) can cause major problems in your code. This is because non-text based word processing programs insert extra formatting into text files, and can corrupt the files when they need to be interpreted by the interpreter. An editor like Notepad does not insert any extra formatting.

Edit WordPress Files with a text only editor.

Some examples of file formats which need to be edited as plain text:

Some examples of text editor programs:

Some examples of non-plain text formats that require special software for editing:

  • Microsoft Word documents
  • Microsoft Excel spreadsheets
  • Images, such as JPEG, PNG, or GIF

Some examples of software which can edit text, but which are NOT regarded as basic text editors and NOT recommended for use on WordPress files:

  • Microsoft Word
  • Microsoft Works
  • Microsoft Excel
  • Adobe Photoshop
  • Adobe Illustrator

バイナリ

Binaries refer to compiled computer programs, or executables. Many open source projects, which can be re-compiled from source code, offer pre-compiled binaries for the most popular platforms and operating systems.

配列

An array is one of the basic data structures used in computer programming. An array contains a list (or vector) of items such as numeric or string values. Arrays allow programmers to randomly access data. Data can be stored in either one-dimensional or multi-dimensional arrays.

A one-dimension array seven (7) elements would be:

105 200 54 53 102 13 405

The Template Tag list_cats() uses a one-dimensional array for the 'exclude' parameter.

An example of two-dimensional array, 7 by 3 elements in size, would be:

105 200 54 53 102 13 405
15 210 14 513 2 2313 4512
501 500 499 488 552 75 1952
