The internet infrastructure is made up of a complex network of hardware and software components. At the lowest level, the Internet is composed of physical infrastructure, including cables, routers, and switches, as well as the computers, servers, and other devices that make up the network. Data packets travel along these physical pathways, which are connected to each other via different types of network technologies.
At the higher level, software applications such as web browsers, email clients, and other Internet-enabled programs make use of the physical infrastructure to send and receive data. This data is routed through the Internet backbone, which is made up of high-speed fiber-optic cables that connect major cities around the world. Finally, data is delivered to end-users through their local Internet Service Provider, which provides the connection between the user’s computer and the Internet.
