Themes And Plugins

Themes

WordPress users may install and switch between themes. Themes allow users to change the look and functionality of a WordPress website and they can be installed without altering the content or health of the site. Every WordPress website requires at least one theme to be present and every theme should be designed using WordPress standards with structured PHP, valid HTML and Cascading Style Sheets (CSS). Themes may be directly installed using the WordPress “Appearance” administration tool in the dashboard or theme folders may be uploaded via FTP. The PHP, HTML (HyperText Markup Language) and CSS code found in themes can be added to or edited for providing advanced features.

WordPress themes are in general classified into two categories, free themes and premium themes. All the free themes are listed in the WordPress theme directory and premium themes should be purchased from marketplaces and individual WordPress developers. WordPress users may also create and develop their own custom themes if they have the knowledge and skill to do so. If WordPress users do not have themes development knowledge then they may download and use free WordPress themes from wordpress.org.

Plugins

WordPress’s plugin architecture allows users to extend the features and functionality of a website or blog. WordPress has over 40,501 plugins available, each of which offers custom functions and features enabling users to tailor their sites to their specific needs. These customizations range from search engine optimization, to client portals used to display private information to logged in users, to content management systems, to content displaying features, such as the addition of widgets and navigation bars. But not all available plugins are always abreast with the upgrades and as a result they may not function properly or may not function at all.

What is Knowledge Base

A knowledge base (KB) is a technology used to store complex structured and unstructured information used by a computer system.

The initial use of the term was in connection with expert systems which were the first knowledge-based systems.The original use of the term knowledge-base was to describe one of the two sub-systems of a knowledge-based system. A knowledge-based system consists of a knowledge-base that represents facts about the world and an inference engine that can reason about those facts and use rules and other forms of logic to deduce new facts or highlight inconsistencies. The term “knowledge-base” was coined to distinguish this form of knowledge store from the more common and widely-used term database. At the time (the 1970s) virtually all large Management Information Systems stored their data in some type of hierarchical or relational database. At this point in the history of Information Technology the distinction between a database and a knowledge base was clear and unambiguous.
