Things we’ll explore today: 1) Explain how to access and connect to the Internet2) Analyze an IP address & domain name ICT Project Group 2: Damian Ho, Joel Soh, Kang Yue Ran, Jovan Lee and Jon Tan
Accessing the Internet Things You Will Need: • An ISP (Internet Service Provider) Some ISPs provide unlimited data usage for a fixed monthly price. • A Modem with an Antenna • A Web Browser A Web Browser is a program that allows you to surf the web (For example, Firefox or Google Chrome) • An Email Programme An Email service is essential to send and receive electronic mail, and is sometimes needed for configuration when connecting to a new ISP.
Connecting to the internet • First, use the set up CD provided by the modem company. It will take you through the steps to setting it up. • To connect to the internet, first go to your internet connection on your task bar. • Next, simply look through the networks available and choose yours. Once done you should be able to access your internet.

What is an IP address? • It is a unique identifier for each machine on a network. It is used to send data to specific computers on a network. • There are two standards for IP addresses: IPv4 and IPv6 • In the next two slides, we will analyse both of them.
IPv4 (Internet Protocol version 4) • IPv4 uses 32 binary bits to create a single unique address on a network. • With this system, there are 4,294,967,296 unique combinations, which as of now have almost run out. • It is the fourth version in the development of Internet Protocol and it is the first version to have been widely deployed. IPv4 Address
IPv6 (Internet Protocol version 6) • IPv6 on the other hand uses 128 binary bits to create a single unique address on a network. • It was developed to deal with the long-anticipated problem of IPv4 address exhaustion. • In the IPv6 system, there are 2128, or about 3.4×1038 possible addresses, or more than 7.9×1028 times more than IPv4. • As IPv4 and IPv6 were not designed to be interoperable, the transition to IPv6 will most likely be complicated. IPv6 Address
What is an Domain Name? Credits Group Leader – Damian Ho Information Sourcer – Kang Yue Ran Information Sourcer – Jon Tan Editor – Joel Soh Slide Manager – Jovan Lee • Short for Domain Name System, DNS is an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they’re easier to remember. • Every time you use a domain name (e.g. google.com), you use the internet’s domain name servers to translate the domain name into machine-readable IP addresses (e.g. 184.108.40.206)
