Another missed lecture and tutorial for Data Communications which I definitely regret as the subject is very interesting.
Week 7 focused on Local Area Networks, the reasons for them, how they work and how to implement them.
Some ways to increases speed of server based LAN is to increase the number of NICs [Network Interface Cards] in the server, or upgrade to a faster network protocol (ie: to fibre).
The tutorial work analyzed the flow of packet through a typical LAN as illustrated above.
Some notes from the lecture:
NOS [Network Operating System]
- Server version of NOS
- Client version of NOS
- Network Profiles
- Directory Service
- Examples – Linux, Windows Server, Windows NT
Distinguishing features of LAN – Clients, Server, cables, NOS, Switch.
A good description of the difference between hubs, switches and routers: http://ask-leo.com/whats_the_difference_between_a_hub_a_switch_and_a_router.html
