Progressive Hospital Case study 1. Background Progressive Hospital is split over two sites: Remuera and City Centre and is run by the City Centre Health Board (CCHB). The sites are connected by a dedicated fiber link and are managed as one network. There are also 30 Community Clinics which access the Hospital’s network using Telecom’s Frame Relay service. CCHB has approximately 15000 users and 200 servers. 1 Local Area Network 1 Network setup within each site:

model of communication‚ the Media Access Control layer is one of two sub layers of the Data Link Control layer and is concerned with sharing the physical connection to the network among several computers. Each computer has its own unique MAC address. Ethernet is an example of a protocol that works at the Media Access Control layer level. There are two basic media access control methods for shared media: 1. Controlled access method. 2. Contention based access method. Controlled accessed method: When using

Exercise 4.1.2 The voltage for registering a bit of 1 on Ethernet can be as low as 2.5 volts or even 1 volt. Why is this so low when the capacity for transmitting electricity on the copper wire is so high? Because the voltage used to transmit data needs only be high enough for the
