Many web hosts offer limited features in their starter packages and then expand the offerings (sometimes tremendously) for higher-tier plans. Read the small print to make sure the plan you are selecting offers what you need. If you need a site builder application to design your website, make sure that the low-cost web host you are picking actually comes with a site builder. Many of them require you to pay for the builder as a separate add-on. Website builders usually don't cost a lot of money, but if you can find a web host that includes one for free, that's money in your pocket. And, if it's integrated with your hosting service, you're more likely to have a smooth, supported experience.
Unlike traditional client/server models, such as a Web server/Web page system, Web services do not provide the user with a GUI. Web services instead share business logic, data and processes through a programmatic interface across a network. The applications interface, not the users. Developers can then add the Web service to a GUI (such as a Web page or an executable program) to offer specific functionality to users.
