Welcome back.


The course consists of practical work in the
laboratory and lectures in computer network
ing.
We have access to room
3
-

8
where there is Cisco network equipment, so very practical
work
on networks
can be done there.

We will call it the
Cisco Lab


M
ethodology

There will be weekly assessments
(normally) and a

written examination in May 2013
.

I advise all students to attend regularly as the material builds on the previous lecture. I use
the Cisco material from the
Cisco
Network Academy

and all students
will
have access to
this.

You are not required to buy any books.

However for those who like to have a book

instead of a screen
, there
is a book that covers the entire course:

Book:
Network Fundamentals, CCNA Exploration Companion Guide
.

Authors: Mark Dye et al.


Online
course mat
erial is on the website

The C
isco Network Academy is at

http://cisco.netacad.net/

The weekly assessments are done in the computer laboratory as per timetable. The
assessments consist of online exams on a Cisco server and the results are given immediately
and recorded in the
student
gradebook

on the server
.


Software: Packet Tracer

This
is software that allows simulation of networking. The so
ftware will be used to simulate
networking with exercises in each chapter of the book or course material.

The
same
exercises
can be done live in the Cisco Laboratory
.
