Here's what the individual words mean:
* El: The (masculine singular definite article)
* Ceco: This could be a shortened version of "centro de cómputo" (computer center), but that's not a standard way to refer to it.
Could you please provide more context about where you heard "el ceco"? For example:
* What were you reading or watching?
* Who said it?
* What was the general topic of the conversation?
With more information, I can give you a more accurate translation.
