The CPU and OS types are detected by the client and sent to the servers when requesting assignments. They can influence what sort of work will be assigned, and which core URL is given to the client. Each of these types is reported as a pair of numbers, the first of which is a basic type defined by Cosm, and the second of which is a subtype determined by the client. The most detail is available for Windows systems running on Intel CPUs. The numbers are sometimes stored in little-endian order in queue.dat, and sometimes in big-endian order, with no clearly consistent pattern. If qd recognizes the pair of numbers, it prints a string which interprets them.

The full set of numbers are: CPU Type, CPU Species, OS Type and OS Species.
