Introduction to web concepts
The Internet can be thought of as an enormous network of
interconnected computer equipment, through which documents,
data, orders and instructions are distributed in every direction. In a
sense, the Internet is the physical element that allows information
to flow between servers, nodes and computers connected either
through cables or fibre optics.
The Internet began in 1969 as part of the research carried out by a
US government agency called ARPA (Advanced Research Projects
Agency) together with four universities. Each university had a
computer which acted as a node. All the computers were connected
to each other thanks to the use of the same protocol prior to the
present TCP/IP, which was integrated as the only protocol in 1973.
