The Internet is a global network that connects computers around the world through wires. It began in the late 1950s and saw rapid growth in the 1970s and 1980s as more computers and networks were connected. By the early 2000s there were over 200 million connected hosts. The Internet allows for fast communication and entertainment through browsing websites, searching online, downloading content, and more. While it provides advantages like cheap communication and access to news and education, it also enables certain disadvantages like encouraging violence, pornography, and reducing outdoor activity for some users.
