Match the following words with its definition.
A method of transmitting data packets across a network. Each data packet is able to take an individual pathway across the network.
Computers and devices that are joined together using cables or wireless technology.
A network component that examines a data packet to obtain its destination address and then forward the packet to this address.
The unique address that is given to a device when it is connected to a network.

Multiple Choice
True or False: There is only one method of transmitting data.
True
False
What's data?
4
Methods of data transmission
We are going to learn 5 methods:
Serial
Parallel
Simplex
Half-Duplex
Full-Duplex
5
Methods of data transmission
Serial and parallel data transmission involve the number of wires that are used to transmit the data
Simplex, half-duplex and full-duplex transmission involve the direction in which the data is transmitted.
6
Multiple Choice
What are the three types of data transmission methods that describe the direction of data flow between devices?
7
Fill in the Blanks
What are the two types of data transmission methods that describe the number of wires used to transmit data?
8
Serial data transmission
9
Categorize
The data arrives ordered.
The transmission is slow.
Less chance of interference.
It is cheaper.
It requires additional data to confirm the beginning and end of the data transmission.
Organize the advantages and disadvantages of the serial data transmission.
10
Parallel data transmission
11
Categorize
The transmission is quicker than the serial transmission.
The bits do not arrive in order to the destination.
There is no requirement to convert the data into serial data transmission.
More chance to data interference, so more chance of error.
More expensive than the serial data transmissions.
Organize the advantages and disadvantages of the parallel data transmission.

Serial
Parallel
What is a leaflet?
13
Multiple Choice
We need to send very important data over a long distance to a remote server. Which method should we use to connect the computer to the server?
Serial
Parallel
What is a leaflet?
14
Simplex data transmission
15
Open Ended
You would only use simplex type of data transmission when there is no need to send data both ways between the devices.
Can you think of devices that would use simples transmission.
Name devices that don't need to receive data only send.
16
Half-duplex data transmission
17
Fill in the Blanks
