Bitnet was a computer network that connected many universities in the 1980s and 1990s. It was like a really big club where students and professors could share information and messages with each other, almost like sending letters or emails.
Think of it like a big playground where kids from different schools could play together and share their toys. But instead of toys, they were sharing information and messages on their computers.
Bitnet allowed people to send and receive messages, files, and even computer programs from their computer to other computers on the network. It was a really cool way for people to connect with others who had similar interests and share knowledge and ideas.
But just like how people move away and schools start to change, Bitnet eventually slowed down and was replaced by other networks that were faster and could connect with more people.
