With the release of windows me, microsoft added a new built-in utility to their desktop operating systems which allows to roll back system files and settings to an earlier point in time without affecting personal files. it provides a yet another way to undo system changes to the computer when an installation of a new program or device driver causes a problem and uninstalling doesn't fix the problem. the utility's interface contains a list allowing the user to bring back the system to the state it was in before the selected event. items on that list are called:

When making changes to optimize part of a processor, it is often the case that speeding up one type of instruction comes at the cost of slowing down something else. for example, if we put in a complicated fast floating-point unit, that takes space, and something might have to be moved farther away from the middle to accommodate it, adding an extra cycle in delay to reach that unit. the basic amdahl's law equation does not take into account this trade-off. a. if the new fast floating-point unit speeds up floating-point operations by, on average, 2ă—, and floating-point operations take 20% of the original program's execution time, what is the overall speedup (ignoring the penalty to any other instructions)? b. now assume that speeding up the floating-point unit slowed down data cache accesses, resulting in a 1.5ă— slowdown (or 2/3 speedup). data cache accesses consume 10% of the execution time. what is the overall speedup now? c. after implementing the new floating-point operations, what percentage of execution time is spent on floating-point operations? what percentage is spent on data cache accesses?
