How did colossus work verses modern computer?

Colossus, developed during World War II, was one of the first programmable digital computers, primarily used for codebreaking. It operated using thousands of vacuum tubes to perform Boolean logic operations, processing data in a serial manner. In contrast, modern computers utilize microprocessors with billions of transistors that enable parallel processing, vastly increasing speed and efficiency. Additionally, modern computers are highly versatile, capable of running various software applications, whereas Colossus was specifically designed for a singular task.
