Abstract: Computer systems linked to nodes in a communication network communicate directly with each other to establish name associations for entities (e.g. programs, storage files, etc.) susceptible of being shared across the network, and thereafter communicate further by names (rather than addresses) to establish sessions (i.e. logical connections over the network) between entities. Each system maintains a table of names assigned to locally accessible entities. The name and session establishment processes are architected to avoid dependence on any "central" or "master" system, and to allow for extension of communications relating to these processes across devices linking portions of the network associated with different communication media or channels.

Abstract: In a computer system, paging operates and a method of use thereof are provided for extending the addressing capability of a processor by using a page register. The page register includes means for storing different codes for different operations to be performed on the memory. The memory is divided into four groups of memory within 2.sup.n addresses such that there is paged and unpaged ROM and paged and unpaged RAM. The unpaged ROM and RAM include only a single block which is directly addressed by the n bit address bus. The paged ROM and RAM includes a plurality of blocks or pages, one of which is selected to be addressed by the page register. The page register responds to the address bus and to signals from the processor defining the memory operation to be performed by providing page signals, selecting one page of paged memory.
