1.1 and 1.2.

As modern technology advances, the number of ways to access the internet increases in both ways and speed.
Computers gain internet access usually through hard lining a router to the PC using an Ethernet cable which means you are unable to move around with your computer without removing the cable  meaning you lose the internet connection. Originally computers gained their internet access through a Dial-up modem which was slow to connect and slow to use. Dial-up modems would also take up the full use of your phone line so you could only use one or the other. Now with broadband and fibre-optic cables internet speeds have increased and no longer interfere with the phone line, (however a phone line connection is still required for this to work!) While hard lining the router to the PC is still the usual way to go for fastest speeds and stability, the new ways of accessing the internet allow wireless internet connections known as Wi-Fi. This gives you freedom of movement, usually with smaller hand held devices such as laptops, tablets and mobile phones. This new internet connection method does still have its drawbacks though, the further you are from the router the weaker the connection thus the slower the internet speed, and if you get too far from the router, the connection is lost completely and you have to move back within range of the router.


Mobile phones gain their internet connection (when not connected to Wi-Fi) through 3G/4G. Like the ability to connect online with computers, the capabilities to get online with mobile phones has advanced significantly in location and speed. 3G now has the ability to cover approximately 95% of England's populated areas and 4G, which is the newest form of mobile internet connection is currently in the process of expanding its reach around the country with data transfer speeds that are at least 10 times greater than that of 3G! Laptops can also take advantage of the 3G and 4G bandwidths by using a Dongle that plugs into a USB slot to supply it with an internet connection.
