Multiprocessor Operating Systems
Direct Addressing in computer systems architecture is when the number in the address field of the instruction is the actual memory address to be accessed.
Multiprocessor systems have gained popularity over the years as they allow the user to do more than they could with a single processor system. Xbox 360, CELL, and Sequent are examples of multiprocessor systems.
is a number of linked systems, working together closely ,so that they form a single computer
