The Internet

The Internet is a global network of interconnected computers that communicate using standardized protocols, allowing for the sharing of information and resources.

DNS stands for Domain Name System. It translates human-readable domain names (like www.example.com) into IP addresses that computers use to identify each other on the network.

ARPANET (Advanced Research Projects Agency Network) was the first operational packet-switching network and the predecessor of the modern Internet, developed in the late 1960s.

Tim Berners-Lee is a British computer scientist best known for inventing the World Wide Web while working at CERN in the late 1980s.

The first message intended to be sent over the Internet was 'LOGIN', but the system crashed after sending just the letters 'L' and 'O'.

An IP address (Internet Protocol address) is a unique string of numbers separated by periods (IPv4) or colons (IPv6) that identifies each computer using the Internet Protocol to communicate over a network.

The World Wide Web is a system of interlinked hypertext documents accessed via the Internet, using web browsers to view pages that may contain text, images, videos, and other multimedia.

Modems (modulator-demodulators) convert digital data from a computer into analog for transmission over telephone lines and vice versa, enabling Internet access.

Packet switching is a method of data transmission where data is broken into packets that are sent independently over the network and reassembled at the destination.

A web browser is a software application used to access and view websites on the Internet, such as Google Chrome, Mozilla Firefox, and Safari.
