Pictured are CN students Kawakami Masashi (left), Evelyne Benie (center), and Shashindra Bhandari (right). They are learning about the different components of a data communication system and different line configurations. Different components include a switch, which connects computers together; a server, which stores network data; and a modem which enables computers to communicate with each other. Line configurations are the actual order that individual wires have to be in so that the network functions correctly.

Pictured are Wade Mickelsen (left), Allan Reko (center), and Jason Nordmann (right). They are creating a Star topology network consisting of a hub, server, four workstations and a printer. A Star topology is a network with all of the computers on the perimeter being connected centrally by a switch.

Pictured are CNA 425 students Adeel Ahmed (left), Curt Richter (center), and Jeff Keenan (right). They are working on a lab which involves creating a computer topology, learning about line configurations and the key elements of a protocol. A topology is the design of the network and physical layout of its equipment. Line configurations are the actual order that individual wires have to be in so that the network functions correctly. A protocol is a certain system that computers use to communicate on a network.


CNA 485 Servers - Click to Enlarge

Pictured is a server installed with Windows Server 2003 software (top) and a server installed with Windows XP Professional software (bottom). These are used by a CNA 485 class for learning about network topologies. A topology is the design of the network and physical layout of its equipment.


Computer Networking and Applications Club Lab - Click to Enlarge

Pictured is the Computer Networking and Applications Club Lab. The lab has 20 Compaq and Hewlett-Packerd computers networked to a Windows server and a Linux server. The Windows server is installed with Windows Server 2003 software and the Linux server is installed with Mandrake software.


Smart Switch 6500 - Click to Enlarge

Pictured is a Smart Switch 6500. A switch is designed to connect two or more computers. The Smart Switch is actually seven switches in one. On top of the Smart Switch is a Tiger Switch. Unlike the Smart Switch, which has separate compartments for each switch, the Tiger Switch is made to be mounted in a rack.

Displayed is a switch that has been taken out for replacement from the Smart Switch 6500. The problem with the switch is that the circuits which allow it to communicate with the central processing chip of a computer are broken, which is also known as a short circuit.
