That's exactly what it means, though I think the word "buffer" would be more appropriate.

cache [noun]: a temporary storage space or memory that allows fast access to data.

buffer [noun]: a storage device for temporarily holding data until the computer is ready to receive 
or process the data, as when a receiving unit has an operating speed lower than that of the unit 
feeding data to it.
