The Internet is not a physical place, using the conventional concept of a place - with a location that has physical dimensions. The net is as massive "highway" of wires, optical fiber cables, and microwave links - connected by relay hardware called "routers" and "hubs" to dedicated computers called "servers". Those servers buy space (bandwidth) on various locations on the net (the main trunk lines of the net are called "the backbone" and carry the main bulk of the signals) and rent out that space to companies that wish to host web sites. The browser on your computer or smart phone or tablet receives near-Human readable code over the net from those servers - and create web-pages out of them - no web-page is transmitted the way you see it by your browser. The code is written in a language called "hyper-text markup language (html)" following a set of rules called "a protocol" (http) and is authored on software on local computers, tested, and uploaded to the server - and then propagated through the entire net - to special location servers so the address you type into your browser can find the web-page. Other technologies are typically included in web-pages such as Java (small code originally invented by Sun Microsystems to run toys) and various audio/video multi-media coding software. So technically speaking, you can't walk into the net - it doesn't exist in physical space (the wiring,connections, and servers do) - you can think of it an an illusion of a place - created to make communication easier across the net - typically using the World Wide Web that sits "on top" of the connections.
