“KB” usually means kilobyte , a computer-data unit, and “TK” usually means to come or a placeholder for text that will be added later. So “maximum kb tk” is not standard English by itself; it looks like shorthand or a mixed phrase where KB = kilobyte and TK = to come/placeholding text.

Most likely meanings

  • KB = kilobyte, a unit of computer storage or data size.
  • TK = “to come,” used in editing to mark missing information.
  • Put together, “maximum kb tk” could mean something like “maximum kilobytes to come,” but that is not a normal fixed phrase in English.

In plain English

If you saw it in a document or post, it probably means the writer was using shorthand and left part of the text unfinished. In a technical context, it may refer to a data-size limit in kilobytes, while TK is just a placeholder.

Best translation

A natural English rendering would be:

“maximum kilobytes, to be added later”

or, if it was just a placeholder:

“maximum KB: TK”
