I'd like to ask about the meaning of "come in" in the following context:
When an image is captured on a digital camera’s CCD array, it then has to be transferred somewhere else for storage before the camera can take another picture. This storage is usually done on small, removable, high-tech discs that come in the same capacities already well familiar to us from computers.
This is not 'come in' as in welcoming someone into your home.
'come' here is used in the sense:
be sold, available, or found in a particular form : "Does this shirt come in blue?" ""This car comes with metallic paint and GPS." "The food processor comes with all attachments for shredding and slicing."
