Web Content Management Systems

January 27th, 2010

Website management is one of the tasks that needs some system to create, edit and manage content. Web pages are a typical example of content. You need some editor to create pages, some database to store them and some system to generate and retrieve pages when they are needed.

Web Content Management System (CMS) is a web application designed for creating and managing HTML content–web pages. Web CMS is used to manage a large collection of web resources (text, HTML code, images, PHP scripts, etc). Web CMS functions usually include: content creation, content control, content editing, maintenance functions, and functions special to each CMS. In general, web content management software applications provide authoring tools designed to allow users with little or no knowledge of programming languages or markup languages to create and manage content with relative ease. Therefore you don’t have to know anything about HTML, CSS, PHP, JavaScript, AJAX or other fancy codes.

Web content management systems use a database to store content, metadata, or additional data that might be needed by the system. A web CMS usually contains a presentation layer which displays the content to web-site visitors based on a set of templates. A template is a basic page layout that contains content place holders, page styles and other page data that does not change.

Most web CMS applications use server side caching to boost performance. This works best when the web content is not changed often but visits happen on a regular basis. Administration of web CMS is typically done through web-based interfaces, but some systems require the use of a desktop client. A web CMS typically requires an experienced administrator to set up and add features, but is primarily a Web-site maintenance tool for non-technical administrators. It allows non-technical users to easily make changes to a website with little or no training.

There are many open-source web Content Management Systems you can download and use for free. Some well known free CMS systems are Wordpress, Joomla, and Drupal to mention only the most popular. Those mentioned are based on PHP scripting language. There are also other CMS applications based on other languages like.NET, ASP.NET, Java, Java Bundle, Perl, Python, Ruby on Rails, etc.

Software-a Computer Program

December 12th, 2008

Software, computer programs; instructions that cause the hardware-the machines-to do work. Software as a whole can be divided into a number of categories based on the types of work done by programs. The two primary software categories are operating systems (system software), which control the workings of the computer, and application software, which addresses the multitude of tasks for which people use computers. System software thus handles such essential, but often invisible, chores as maintaining disk files and managing the screen, whereas application buy software performs word processing, database management, and the like. Two additional categories that are neither system nor application software, although they contain elements of both, are network software, which enables groups of computers to communicate, and language software, which provides programmers with the tools they need to write programs.

In addition to these task-based categories, several types of software are described based on their method of distribution. These include the so-called canned programs or packaged software developed and sold primarily through retail outlets; freeware and public-domain software, which is made available without cost by its developer; shareware, which is similar to freeware but usually carries a small fee for those who like the program; and the infamous vaporware, which is software that either does not reach the market or appears much later than promised. In addition to a computer’s speed the usability of the software and the ergonomic design of the physical components are important considerations. Usability is the ease with which a person learns to use an application, as well as how efficient and effective it is. Ergonomics determines how people function in relation to their environment, and with respect to computers, how to make input and output devices easy, comfortable, and efficient to use.

Voice over Internet Protocol (VoIP) is basically a process, which converts your voice into digital signals that travel over internet. Its most prominent feature is its affordability. With VoIP you can make long distance calls at a fraction of cost that you used to pay to your telephone companies.
