The basic service is the e-mail system itself. Effective e-mail systems will allow the exchange of mail with different mail systems using international industry standards. This allows for the exchange of e-mail between Internet mail servers. A POP service allows someone on a personal computer to easily fetch mail from an SMTP mail server. POP service does not require the computer to always be available to receive mail.
POP also supports friendlier user interfaces on personal computers for reading mail.
Network News Groups Network news groups let people with shared interests communicate about a particular subject area. The information shared through news groups is mainly simple text, which makes news groups useable over low-bandwidth connections. The effective use of a news group is directly related to the size and interests of the group. Probably the fastest growth in use of the Internet is with public information servers such as the World Wide Web. Bandwidth requirements for these services are a function of the type of service and also the role, whether client or server.
