Document Summary

Dma is a problem with multiple cpu"s. To improve system performance in a computer: multiple cpus, faster clock speed, wider instruction and data path, faster disc access, more and faster memory. Multiprocessing increases parallel processing: 2 types are tightly processing:each system has its own cpu, each sys known as a node, loosely coupled systems: extends multitasking and program execution. A masterslave processing is a master cpu that controls the system its simple but if it fails, the whole system does. The osi model was created by iso. Ring network topology is bus is closed no ends. undirectional and pnt to pnt. Star is a central node does most of the processing remote nodes are connected point to point with it. Loop is similar to ring, nodes directly in communication path. Web is everything connected to everything else. Mac are characteristics of the channels , data , rate ,voltage lvls etc. detects errors has ethernet and token ring.
