The internet is a global network of interconnected computers, servers, and other devices that allow people to communicate and access information from anywhere in the world. It was first developed in the 1960s as a way for researchers and scientists to share data and communicate with each other, but has since evolved into a vast network that is used by billions of people around the world for a variety of purposes.
It is made up of a vast number of interconnected networks that use a variety of technologies and protocols to transmit data. These networks are connected through a series of servers, switches, and other hardware that allow devices to communicate with each other and access the vast amount of information that is available online.
