Shoutbox
A shoutbox, saybox, tagboard, chatterbox or chat box is a chat-like feature of some websites that allows people to quickly leave messages on the website, generally without any form of user registration. In their simplest form, shoutboxes are simply lists of short messages, possibly with information about their authors. The page may be automatically refreshed after a certain interval, or polled dynamically in order to keep new messages visible. Older posts are often deleted after a certain number of messages have been written in order to preserve space on the server. Technology Shoutboxes are embedded into a page with inline frames or JavaScript. Many Internet forum and web blog software packages can be modified to add shoutboxes in sidebars on site pages. Shoutboxes are usually maintained in a manner similar to that of more complex boards, with moderators that can delete posts and ban usernames or IP addresses. Occasionally, features such as impostor identification, flood contr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Chat
A web chat is a system that allows users to communicate in real-time using easily accessible web interfaces. It is a type of Internet online chat distinguished by its simplicity and accessibility to users who do not wish to take the time to install and learn to use specialized chat software. This trait allows users instantaneous access and only a web browser is required to chat. Users will always get the latest version of a chat service because no software installation or update are required.

Internet Forum
An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages. They differ from chat rooms in that messages are often longer than one line of text, and are at least temporarily archived. Also, depending on the access level of a user or the forum set-up, a posted message might need to be approved by a moderator before it becomes publicly visible. Forums have a specific set of jargon associated with them; example: a single conversation is called a " thread", or ''topic''. A discussion forum is hierarchical or tree-like in structure: a forum can contain a number of subforums, each of which may have several topics. Within a forum's topic, each new discussion started is called a thread and can be replied to by as many people as so wish. Depending on the forum's settings, users can be anonymous or have to register with the forum and then subsequently log in to post messages. On most forums, users do not have to ...

Online Chat
Online chat may refer to any kind of communication over the Internet that offers a real-time transmission of text messages from sender to receiver. Chat messages are generally short in order to enable other participants to respond quickly. Thereby, a feeling similar to a spoken conversation is created, which distinguishes chatting from other text-based online communication forms such as Internet forums and email. Online chat may address point-to-point communications as well as multicast communications from one sender to many receivers and voice and video chat, or may be a feature of a web conferencing service. Online chat in a less stringent definition may be primarily any direct text-based or video-based (webcams), one-on-one chat or one-to-many group chat (formally also known as synchronous conferencing), using tools such as instant messengers, Internet Relay Chat (IRC), talkers and possibly MUDs or other online games. The expression ''online chat'' comes from the word '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Website
A website (also written as a web site) is a collection of web pages and related content that is identified by a common domain name and published on at least one web server. Examples of notable websites are Google, Facebook, Amazon, and Wikipedia. All publicly accessible websites collectively constitute the World Wide Web. There are also private websites that can only be accessed on a private network, such as a company's internal website for its employees. Websites are typically dedicated to a particular topic or purpose, such as news, education, commerce, entertainment or social networking. Hyperlinking between web pages guides the navigation of the site, which often starts with a home page. Users can access websites on a range of devices, including desktops, laptops, tablets, and smartphones. The app used on these devices is called a Web browser. History The World Wide Web (WWW) was created in 1989 by the British CERN computer scientist Tim Berners-Lee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
User Registration
A registered user is a user of a website, program, or other systems who has previously ''registered.'' Registered users normally provide some sort of credentials (such as a username or e-mail address, and a password) to the system in order to prove their identity: this is known as logging in. Systems intended for use by the general public often allow any user to register simply by selecting a ''register'' or ''sign up'' function and providing these credentials for the first time. Registered users may be granted privileges beyond those granted to unregistered users. Rationale User registration and login enables a system to personalize itself. For example, a website might display a welcome banner with the user's name and change its appearance or behavior according to preferences indicated by the user. The system may also allow a logged-in user to send and receive messages, and to view and modify personal files or other information. Criticism Privacy concerns Registration nec ...

Framing (World Wide Web)
In the context of a web browser, a frame is a part of a web page or browser window which displays content independent of its container, with the ability to load content independently. The HTML or media elements shown in a frame may come from a different web site as the other elements of content on display, although this practice, known as framing, is today often regarded as a violation of same-origin policy. In HTML, a frameset is a group of named frames to which web pages and media can be directed; an iframe provides for a frame to be placed inside the body of a document. Since the early 2000s, the use of framesets has been considered obsolete due to usability and accessibility concerns, and the feature has been removed from the HTML5 standard. Tags and attributes The frames in HTML are created using the tag pair. The tag is a container tag for all other tags that are used to create frames. The tag replaces the tag in frameset documents.The tag defines how to divide th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blog
A blog (a Clipping (morphology), truncation of "weblog") is a discussion or informational website published on the World Wide Web consisting of discrete, often informal diary-style text entries (posts). Posts are typically displayed in Reverse chronology, reverse chronological order so that the most recent post appears first, at the top of the web page. Until 2009, blogs were usually the work of a single individual, occasionally of a small group, and often covered a single subject or topic. In the 2010s, "multi-author blogs" (MABs) emerged, featuring the writing of multiple authors and sometimes professionally Editing, edited. MABs from newspapers, other News media, media outlets, universities, think tanks, advocacy groups, and similar institutions account for an increasing quantity of blog Web traffic, traffic. The rise of Twitter and other "microblogging" systems helps integrate MABs and single-author blogs into the news media. ''Blog'' can also be used as a verb, meaning ''to ...

Memcached
Memcached (pronounced variously ''mem-cash-dee'' or ''mem-cashed'') is a general-purpose distributed memory-caching system. It is often used to speed up dynamic database-driven websites by caching data and objects in RAM to reduce the number of times an external data source (such as a database or API) must be read. Memcached is free and open-source software, licensed under the Revised BSD license. Memcached runs on Unix-like operating systems ( Linux and macOS) and on Microsoft Windows. It depends on the libevent library. Memcached's APIs provide a very large hash table distributed across multiple machines. When the table is full, subsequent inserts cause older data to be purged in least recently used (LRU) order. Applications using Memcached typically layer requests and additions into RAM before falling back on a slower backing store, such as a database. Memcached has no internal mechanism to track misses which may happen. However, some third party utilities provide this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat File
A flat-file database is a database stored in a file called a flat file. Records follow a uniform format, and there are no structures for indexing or recognizing relationships between records. The file is simple. A flat file can be a plain text file (e.g. csv, txt or tsv), or a binary file. Relationships can be inferred from the data in the database, but the database format itself does not make those relationships explicit. The term has generally implied a small database, but very large databases can also be flat. Overview Plain text files usually contain one record per line. There are different conventions for depicting data. In comma-separated values and delimiter-separated values files, fields can be separated by delimiters such as comma or tab characters. In other cases, each field may have a fixed length; short values may be padded with space characters. Extra formatting may be needed to avoid delimiter collision. Using delimiters incurs some overhead i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guestbook
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 abou ...

Textboard
A textboard is a simple kind of Internet forum; most textboards require neither registration nor entry of a screen name. Textboards, like imageboards, were invented in Japan, but they remain relatively unknown outside it, in contrast to imageboards (such as 4chan). Features One of the key differences between textboards and traditional forums is that textboards allow users to post without registration, and often encourage anonymous discussion. Hiroyuki Nishimura, the founder of 2channel, says that the philosophy behind anonymous posting is that "all information is treated equally; only an accurate argument will work". Many textboards support a form of pseudo-registration by allowing users to use tripcodes, although users tend to post anonymously. Textboards tend to be much simpler than traditional forums. While forums software such as phpBB or vBulletin supports image or other media embedding, private messaging, polls, and various other features, textboards allow only the pos ...
