Why was a bug attracted to the ENIAC?

A bug was attracted to the ENIAC (Electronic Numerical Integrator and Computer) because it was a complex machine that generated heat and had numerous electrical components, creating an environment where insects might wander. The famous incident involved a moth that got caught in the relay of the computer, causing a malfunction. This event led to the popularization of the term "debugging" in computing, as engineers literally removed the bug to fix the issue. The incident highlighted the challenges of early computer engineering and the importance of maintaining hardware.
