Millions of businesses use the Internet as a cost-effective communications channel. It lets them exchange information with their target market and make fast, secure transactions. Web applications use a combination of server-side scripts to handle the storage and retrieval of the information, and client-side to present information to users. This allows users to interact with the company using online forms, content management systems and more. In addition, the applications allow employees to create documents, share information, collaborate on projects, and work on common documents regardless of location or device.
