Chapter 3.1.5 Network Topology for Form 4, Information & Communication Technology (ICT)

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

2. 3.1.5 NETWORK
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

8. NETWORK TOPOLOGY
So, what is the conclusion that you know
about the 3 different network
topologies?

9. TYPES OF NETWORK TOPOLOGY
RING
BUS
