The Internet provides global access to an agency’s website . The web site is usually on a separate computer or a ‘web server’. The web server can be directly managed by the agency or by a third party . such as an Internet Service Provider (ISP). The agency usually needs to be connected to the web server to process transactions generated by users and to update web site information . Agencies often use the same infrastructure to process emails going into and out of the agency . Because of this there is a continual two-way flow of information traffic into and out of an agency’s network to the Internet.
