Local Area Networks

Figure shows network topology .
Name the topology .

• Tree  topology
• Bus Topology
• Ring topology
• Star topology

What is a LAN?

• Local Area Network
• Local Access Network
• Localized Area Network

What is a characteristic of a LAN?

• Small geographical location such as a school or small office.
• Really cheap to set up.
• Uses less cables than a star.

"To share hardware, software and data" is the answer to the question ...

• Why do we network computers and other devices?
• Why do we use wi-fi all the time?
• Why is a network complicated?

What are two factors that affect network performance?

• Traffic and bandwidth
• Lag and ping
• Banter and bants

What is bandwidth?

• The amount of data that can be carried at any one time.
• The overall amount of data I use in a month.
• The speed of my data per second to a friend and back.

What network topology is this?

• STAR
• BUS
• RING

What network connection type is this?

• Mesh
• Star
• LAN

What is the main advantage of a star topology?

• If a device fails, then the rest of the network can continue to work (unless it is the central point)
• There is no single point where the network can fail

What is the main advantage of a mesh topology?

• If a device fails, then the rest of the network can continue to work (unless it is the central point)
• There is no single point where the network can fail
