Web technology can mean a lot of things. In the world of design we are referring to the applications that exist to help us create websites. To create a professional website you need two programs. A graphic editor and a web coding application. For most professionals that means Adobe Photoshop, and Adobe Dreamweaver. These two programs account for 99.9% of what you need to create a website. In actuality You need a text editor to create a website, however, to create a GUI or graphical interface you will need a graphics program. And, unless you want to spend days creating your site you will need a web coding application like Dreamweaver that will take care of the redundant parts of the coding process.
