The document discusses three common network topologies: bus, ring, and star. The bus topology uses the least cabling but the entire network fails if one connection is lost. Ring networks use tokens to pass data around in a circle, but if a large file is being sent, all users must wait to access the network. Star networks are expensive to implement due to cabling and hub costs but individual connections will still work even if the hub or one connection fails. In conclusion, the document compares the characteristics of bus, ring, and star network topologies.

1. ACTIVITY
Draw 3 basic shapes: train track, ring, & star

TOPOLOGIES

3. ACTIVITY
What can you determine from the angles &
intersection of the 3 objects?

4. NETWORK TOPOLOGY

5. NETWORK TOPOLOGY
• Bus Network
• Is the cheapest
because it uses the
least cabling
• The cables must
have terminators
on the ends
• If one connection is
lost, the whole
network fails

6. NETWORK TOPOLOGY
• Ring Network
• Use tokens to pass data
around the network
• The computer that wants
to send data waits to grab
the token
• Sent to the recipient - it's
ignored by all other
computers
• If it is a large file, all users
have to wait to access the
network

7. NETWORK TOPOLOGY
• Star Network
• Expensive due to cabling
• If one connection is lost,
the rest of the network is
still able to run
• Expensive due to
necessities of a hub
• If the hub fails, the
network fails
• May be the most
expensive, but is the best
in the long-run

So, what is the conclusion that you know
about the 3 different network
topologies?
