Processor technologies and architectures

the current advances the below topics: Processor technologies and architectures Data storage technologies Parallel and multi-processor architectures Data communications technologies Operating systems technologies Device controller technologies Managing security The paper should not address a "history of" or "evolution of" topic. The topic should be focused on current advances (i.e., in the past three to five years). A brief review of relevant historical facts may be worthwhile, but a background discussion more than one page is inappropriate. Keep in mind that this is a computer science course, not a management course. The purpose of the paper is to allow the student to conduct a technically advanced, in-depth study of a single topic.
