B- What We Will Cover Network Architecture Network Layer Model Different Kinds of Networks © John Wiley & Sons Canada, Ltd. B- NETWORK ARCHITECTURE A network architecture refers to the design of a computer system or network. The term usually covers the overall combination of the hardware and software that makes up the network infrastructure. An open architecture is one where anyone can know the design, thus allowing anyone to develop software and hardware to work with it. A closed architecture network has a proprietary design, making it difficult for outsiders to design programs that work with the network. Most of today’s computer systems are open to allow for easy growth. © John Wiley & Sons Canada, Ltd. B- CLIENT/SERVER ARCHITECTURE The most common network architecture is the client/server architecture. © John Wiley & Sons Canada, Ltd. B- CLIENT/SERVER ARCHITECTURE Processing is shared among multiple small computers known as clients that are connected via a network to a host computer known as a server. Clients are typically PCs and workstations, a type of high-powered small computer built for specialized applications. Servers are computers running server software, with each server typically focusing on a specific task. Because both the client and the server are capable of processing, it is shared between the two computers. © John Wiley & Sons Canada, Ltd. B- THREE-TIERED ARCHITECTURE © John Wiley & Sons Canada, Ltd. Three-tiered client/server architecture uses a client, an application server, and a database server. B- TYPES OF SERVERS Server Type Purpose File Provides both software and data files to users Database Handles queries to a large database and returns matching records Application Handles high-speed processing Web Handles requests for web pages Mail Sends and receives e-mail for the entire organization Fax Sends and receives faxes for the
