HRM 3450 Chapter 6 Notes – Summary
Introduction
• The program server can easily limit distribution of the program appropriately.
• The amount of data to be stored, processed, and managed may be extremely large.
• It is more efficient to equip a small number of computers with the power needed than
to require powerful computers at every station.
• Typically, humans request information from knowledgeable sources as they need it.
• Thus, the client-server approach is naturally consistent with the way humans acquire
and use information.
• The most familiar example of the use of client-server technology is the Web browser–
Web server model used in intranets and on the Internet.
• In its simplest form, this model is an example of two-tier architecture.
• Two-tier architecture simply means that there are two computers involved in the
service.
• The key features of this architecture are a client computer running the Web browser
application
• A server computer running the Web server application, a communication link between
them, and a set of standard protocols
• In this case, HTTP, for the communication between the Web applications, HTML for the
data presentation requirements, and, usually, the TCP/IP protocol suite for the
networking communications.
• In the simplest case, a Web browser requests a Web page that is stored as a pre-created
HTML file on the server.
• More commonly, the user is seeking specific information, and a custom Web page must
e reated on the fly, using an appliation program that looks up the required data in
a database, processes the data as necessary, and formats it to build the desired page
dynamically.
