Communication: Changed our world
Technological advancements have made our world so much smaller.
We can video call a friend in India just by swiping our fingers over a screen...we can buy anything anywhere at anytime by just tapping our fingers. We do not even have to have a conversation.

Watch this video and identify as many different types of technologies you can.
1. Transport
A) Faster Air Transport
Jet aircraft has brought cities closer together, this has helped:
- Tourism
- Workforces become more mobile
- Perishable products, such as seafood, can be sent to distant markets

B) Ocean Shipping
- Super Tanker: transport cargo such as oil and wheat.
- Containerisation: goods are packed into large containers at the factory and are directly transported onto the ships.

2. Changes in ICT
A) Telecommunications
- Fibre optic cables and satellites are responsible for massive improvements in global communications.
- A network of cables, laid under the sea and on land, connects the world's major cities.
- Satellites make GPS possible.

B) Computerisation
- Computers revolutionised the storage, retrieval and movement of information in global communications.
- Personal computers became available in the 1980's and the internet was introduced in 1995. The internet allows for information to be easily accessed and shared as well as commercial transactions.

Fibre OPTIC CABLES
A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean. The first submarine communications cables, laid in the 1850s, carried telegraphy traffic. Subsequent generations of cables carried telephone traffic, then data communications traffic. Modern cables use optical fibre technology to carry digital data, which includes telephone and internet.
There are currently 299 ACTIVE cables that are running underneath our seas and oceans today! Let's have a look at where they are... What countries are Australia directed connected to by these cables?
Overland Cable Network in the U.S.A
Acrostic Poem
You will write an acrostic poem about everything you have learnt about Globalisation. You are to ensure that you include information about the Fibre Optic Cables we learnt about today. The poems will be collected at the end of the lesson. If you want a challenge, make it rhyme!
