Suppose we have a deeply pipelined processor, for which we implement a branch-target buffer for the conditional branches only. assume that the misprediction penalty is always four cycles and the buffer miss penalty is always three cycles. assume a 90% hit rate, 80% accuracy, and 10% branch frequency. how much faster is the processor with the branchtarget buffer versus a processor that has a fixed two-cycle branch penalty? assume a base clock cycle per instruction (cpi) without branch stalls of 1.

You are working as a security analyst in a company xyz that owns the whole subnet range of 23.0.0.0/8 and 192.168.0.0/8. while monitoring the data, you find a high number of outbound connections. you see that ip's owned by xyz (internal) and private ip's are communicating to a single public ip. therefore, the internal ip's are sending data to the public ip. after further analysis, you find out that this public ip is a blacklisted ip, and the internal communicating devices are compromised. what kind of attack does the above scenario depict?
