Unit 1

The Internet - "the road" : The infrastructure, think cables, routers, servers, data moving around the world.
The World Wide Web - "the stuff on the roads" : What you use on top of the internet, think websites, links, images, videos and apps.

Web 1.0 "Read-only web" : early version of the web - static pages and limited interaction. Users were able to read and navigate information, but not meaningfully interact/contribute content.
Web 2.0 "Read-write web" : Web changed from passive consumption to an interactive, user generated experience. Writers wanted to participate adn contribute on the web. People were introduced to being able to create/publish content, where blogs, social media, video sharing, and collaborative tools were created.
Web 3.0 "Sematic/Executive web" : extends to be more read-write-execute, and allowed applications to comunicate directly, enabling more intelligent information retrieval and context-aware processing.
Web 4.0 "Mobile web" : Not necessarily a new version but mobile adaptation of existing web technologies, it connects all devices in real and virtual space in real time.
Web 5.0 "Open, linked and intelligent/emotional web" : Also known as symbiotic web, which communicates with users like other humans, acting more like a personal assistant, serves as an emotional interaction between humans and computers.

A URL is an address for a specific resource on the web, think about it like this: Your house has an address, a file has a file path, a website has a URL. Some example resources that a URL might point to: A web page, a video, a PDF, an image, or a Stylesheet
Every valid URL is meant to point to one specific thing.
