[Year 12 SofDev] 2015 Exam Query

Tue Aug 30 10:33:06 AEST 2016

C is nto plausible when setting up a network or with a network already in place where there are no free access points

the cost and labour and time to run a cat 6 utp cable to a particular point inside the walls and then add the actual rj45 is prohibitive
It costs $50 for an electrician to just the wires in the back of an rj45, let alone put the plate in the wall  —> 3 weeks

for your ordinary school network it is merely a matter of putting in a valid user name and password —> ten seconds

very few wired networks run lots of extra points as each point costs well over $100 to install plus cable

Wireless is already there.

Perhaps the question should have clearly excluded ad hoc low effort home networks — but this subject is not about home networks
Very few home networks safely install cable in the walls and wire up proper access points.
I did and that is how I know how much it costs, but there are no OHS issues with cables all over the place.

For example, at home our wireless has a password to access it, but we also use MAC address whitelisting (which is an easy configuration option in the router). It’s far easier to add a new desktop to our network with a Cat5/6 cable than it is to add it via wireless, as we don’t need to enter the MAC address to the white-list if it’s cabled. Adding systems to our wireless network is officially a “pain in the ass” as unless you can easily find the MAC address of the system (which can vary in difficulty depending on what device it is), then the process we need to take is quite tedious.
