Most people often confuse the two terms web development and web designing - they tend to use them interchangeably without even realising that they are completely different. Although any Web Development Company will offer designing services as well, the two terms have absolute different meanings.
Website designing is all about the look and feel of the website whereas development focuses on how a site works and how users get to interact with it. The job of designers is to maintain the beauty of site - they work to make your website look great by putting together all the principles of designing. When users visit your site, they take interest in it and stay for a while on it only if it has eye-catching design. The site should be capable enough to grab attention of potential audience and keep visitors engaged. Website designing is more concerned about graphics, colour schemes, navigation, information (content) and usefulness. Any Website Development Company may have a team of well-experienced website and graphic designers who would have in depth knowledge of designing software such as Photoshop, Illustrator, Corel Draw and Flash.
On the other hand, website development is about building the back-end of your website - after all, a beautiful site has to have a strong foundation too! The team of developers and programmers at any Web Development Company in India or for that matter in any country works together, to make sure that your site functions properly. They need to know technologies such as C++, Java, CSS, HTML, XHTML, ASP.Net, and PHP as well as databases such as My SQL, MY SQL Server, MS ACCESS and Oracle.
However, the two things need to be integrated in perfect harmony to actually build an attractive and highly functional website. The designers need to implement their designs in HTML and developers have to program CGI and scripts like PHP.
