- linear address space — A memory addressing scheme used in processors where the whole memory can be accessed using a single address that fits in a single register or instruction. This contrasts with a segmented memory architecture, such as that used on the Intel 8086, where an address is given by an offset from a base address held in one of the "segment registers". Linear addressing greatly simplifies programming at the assembly language level but requires more instruction word bits to be allocated for an address.

- partitioned data set — (file format) (PDS) A data set on an IBM mainframe that contains members, each of which acts like a separate data set. Partitioned data sets are more space-efficient than individual data sets, because they can put more than one data set on a track. They are also used to hold libraries, with one function per member. The syntax for a member is NAME.OF.PDS(MEMBER) although some systems (such as Phoenix) could use NAME.OF.PDS:MEMBER Original PDSes were of fixed size, and needed frequent compression to recover space after deleting or changing members. Newer PDS/E Extended PDSes do not have this problem.
