simultaneity

Definitions

Astronomy

  • The condition of two events occurring at the same time. One of the key findings of relativity is that all simultaneity is in reality only apparent – a second observer would not see the same events as occurring at the same time as the first one did, or at the same time as each other.

Computing

  • noun in which the CPU and the I/O sections of a computer can handle different data or tasks at the same time
