Networks
- LAN (Local Area Network)
- Devices connected
together over a small
geographical area.
- Connection methods
- WiFi
- Wireless Fidelity. A
wireless method of
connecting to a LAN.
- WiFi has a longer range in
comparison to
Ethernet.
- ...because the signal can be
boosted with a WiFi range
extender.
- ...because the signal can be
boosted with a WiFi range
extender.
- WiFi has slower data
transfer speeds in
comparison to Ethernet
- ...because physical
obstructions, such as
walls, interfere with the
radio waves.
- ...because physical

- Wireless Fidelity. A
wireless method of
connecting to a LAN.
- Ethernet
- A protocol (set of rules) that governs
how data is sent between connected
devices.
- Ethernet has a smaller
range in comparison to
WiFi
- ...because the range is
limited by the length of the
cable.
- ...because the range is
limited by the length of the
cable.
- Ethernet has faster
data transfer speeds in
comparison to WiFi.
- ...because the data does
not get obstructed by
barriers as it travels
directly down the cable to
its destination.

- WiFi
- Hardware
- Router
- Enables a LAN to connect
to a WAN (e.g. the
Internet.) and enables
devices to communicate
with each other in a LAN.
- Enables a LAN to connect
to a WAN (e.g. the
Internet.) and enables
devices to communicate
with each other in a LAN.
- NIC (Network Interface Card)
- Installed in a device, such as a PC, to enable it to
connect to a network by providing a means of
communication between the device and the network
devices (e.g. a router or switch).
- Installed in a device, such as a PC, to enable it to
connect to a network by providing a means of
communication between the device and the network
devices (e.g. a router or switch).
- Switch
- Facilitates (Enables)
communication between multiple
devices in a LAN by directing data to the correct device.
- Facilitates (Enables)
communication between multiple
devices in a LAN by directing data to the correct device.
- WAP (Wireless Access Point)
- Enables WiFi devices to
connect to wired networks.
- Enables WiFi devices to
connect to wired networks.
- Ethernet cable
- Cable used to connect
devices in a LAN
together.
- Cable used to connect
devices in a LAN
together.
- Router
- Enables devices to share data.
- Enables peripherals, such as printers,
to be shared between devices.
- Enables users to communicate via
email (electronic mail).
- Devices connected
together over a small
geographical area.
- WPAN (Wide Personal Area
Network)
- Connection Method
- Bluetooth
- Bluetooth
- A network created by pairing
two devices together over a
small distance
- It is secure because it
is only over a small
distance
- The connection is quite fast
- It does not use up much
power
- It does not use up much
power
- The connection is quite fast
- Connection Method
- WAN (Wide Area Network
- Connection Method
- GPRS (General Packet Radio Service) Mobile Data
- GPRS (General Packet Radio Service) Mobile Data
- You can use it mostly all over the world
- A reasonably fast connection
- Is not very expensive
- Is not very expensive
- A reasonably fast connection
- A network that is all over the
world and is used by almost
everyone and can be
accessed from almost
anywhere
