The internet is a worldwide collection of computer networks. This is the software needed to collect to the internet:

Modem - converts between digital sound produced by computer and analogue signals sent over telephone network; connects to your Internet Service Provider
Router - allows many devices to communicate with each other and share resources i.e. internet connection
Network Adaptor - enables your computer to connect a network - it may be built in like an Ethernet port on a PC or an add-on like a Wi-Fi dongle

An IP address is a unique identifier for every computer accessing the internet. Static IP addresses do not change as they are required by users accessing the web. Whereas, dynamic IP addresses occasionally change, for example PCs.

Domain names identify IP addresses; they are easier to remember than four 8-bit numbers. Domain Name Service translates domain names into corresponding IP addresses.
