Class Slides

Are there any questions from last week??? You should get a copy of the slides and use

them on your computer.

Your lecturer may have to navigate away fromthe slides from time to time and you should havethem for your own study/revision purposes.

To get the slides:

moodle.tafesa.edu.au u/n Student ID

p/w email address (lower case) given by you at enrolment

See your lecturer now if you cant logon

Then browse to the Certificate III and the 3CDH section

38/42


Connect and properly document the networkinstallation


39/42


Perform simple workgroup tasks in order toshare resources


40/42

Summary

Information networks carry data using hosts asclients, servers, or both.

All computer communication involves asource, destination, and channel.

Rules called protocols govern computercommunications.

Larger networks are divided into smaller, more

manageable ones using a layered hierarchicaldesign.

Each network host needs both a physical MACaddress and a logical IP address.

Good network desi n re uires a network lan.

Session 3 Conclusion Are there any questions???

Again, today was fairly heavy going, you must review andre-enforce your knowledge before the next session/class.

If you struggled with today's content, remember thatstudents are supposed to be spending equal

amounts of time studying inside and outside ofclass

The online test for chapter one, two and three should beavailable on the Cisco website during class so study upand take these assessments to give yourself the best

chance of passing 3CDH. All of the content addressed today will be assumed

knowledge next week, I advise you to get organised withthe Packet Tracer software and borrow the IT Academy

software and start studying/practicing
