Models for Networking

Models for Networking
First let’s review some simple models where no networking exits and computers are used in standalone or ad-hoc mode. The following represent some simple models representing classrooms.

Model 1a: One computer in a classroom with its own private printer. It is recommended that schools with computers in this situation would network the classrooms in question as shown. Networking will more effectively make use of commonly shared resources such as file servers and school printers, internet , email etc. When a mobile PC or PC with projector is require in a room the network points are already present.
In this scenario, there could be a single LAN-connected point for the teacher and an additional LAN connection to allow for a portable switch. Refer to diagram 2a

Model 1b: This scenario is similar to Model 1a, but where other equipment such as printers, scanners are used in ad-hoc and inefficient configuration. It is recommended that schools with computers in this situation would network the classrooms in question . Networking will more effectively make use of commonly shared resources such as scanners, printers, internet , email etc. In this scenario there may be a single LAN-connected point for the teacher and a limited number of LAN connection points throughout the room to allow students access to the school LAN. The connection points may be situated as required around the room depending upon class learning requirements and the availability of existing power outlets. Refer to diagram 2b

Networked Computer Room
Model 1c: A non networked computer room or resource area with an ad-hoc and inefficient use of printers, scanners etc. Networking computer rooms is essential so that all PCs can access printers, the internet, email etc. This scenario represents a school computing room which can be timetabled for classes, and with each computer networked to the LAN. There may be a single LAN-connected presentation point for the teacher and LAN-connected computers throughout the classroom. Traditionally, ICT in Irish secondary schools has been concentrated in dedicated computer rooms. Primary schools have more varied deployment. From an administrative point of view, this setup is attractive. An entire class can be timetabled, avoiding problems of extra teachers for split classes. Refer to diagram 2c
