Anewly established internet company with 40 employees needs your advice. they are looking for a collaboration tool and have narrowed their choices to gotomeeting, webex, and my web conferences. after reading the information presented in this chapter and other sources, prepare a two- page document ( double spaced) that includes two advantages and two disadvantages of each tool. which one is your final recommendation? why did you choose that tool over the other two?

Awell-diversified portfolio needs about 20-25 stocks from different categories is this true or false?

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?
