Computer Science & Software Engineering Computer Networks (CITS3230) - unit schedule |
|
||
Unit schedule:
All materials required for laboratory sessions may be found in the local
directory /cslinux/examples/CITS3230/.
The links below point to the materials presented during our 2-hour lecture slots. These materials do not define the whole unit. Attending lectures and reviewing their material comprises about ⅓ of the effort required for this unit. The remainder of your time should be spent reading the textbook, attending tutorials, and attempting the laboratory tasks.
