The Colossus used over how many vacuum tubes to process characters per second?

The Colossus, which was one of the first electronic computers developed during World War II, utilized around 2000 vacuum tubes. This was a significant technological advancement of its time, allowing the machine to perform complex calculations and process data at a much faster rate than previous mechanical computers. It was capable of processing approximately 25000 characters per second, which was incredibly impressive for that era.

The use of vacuum tubes was a critical aspect of the design of the Colossus, as these components allowed for the electronic switching and amplification needed for its operations. This high number of vacuum tubes enabled the computer to execute its tasks with a level of speed and efficiency that laid the groundwork for future developments in computing technology.
