The relative performance of the IBM 360 Model 75 is 50 times that of the 360

The relative performance of the IBM 360 Model 75 is 50 times that of the 360 Model 30, yet the instruction cycle time is only 5 times as fast. How do you account for this discrepancy?

Expert Solution

By comparing other components of the two IBM Machines, this discrepancy can be explained:

Therefore, based on the above mentioned considerations the IBM 360 Model 75 is better than IBM 360 model 30.

Performance of IBM machines:

An IBM 360 Model 75 is 50 times better than that of a IBM 360 model 30 because of some reasons:

• When comparing computer system not only the CPU clock rate should not be taken into account.

• Some of the features like memory system, data rate of memory, cycle time of processor, relative speed, data channels. Data rate on channels.

By comparing other components of the two IBM Machines, this discrepancy can be explained:

Performance Management Process Many times, people confuse performance management with one element of the performance management process: performance appraisal. Performance management is much more than a once or twice a year event. It is a critical process that aligns individual goals and performance with the strategic goals of the organization. In some organizations, performance management is part of an overall talent management or human capital management program, which is the process that organizations use to both attract and retain skilled...

It is estimated that labor costs are between 50 - 75% of the costs of a business. On December 1, 2016, a new labor law was supposed to take effect that would have likely made millions of salaried workers eligible for overtime pay. Certain salaried workers who earn below $47,476 would have been entitled to time-and-a-half wages for each hour they work beyond 40 hours a week. Currently salaried workers $23,660 and above earn no overtime pay even though many...

A tank contains 360 gallons of water and 50 oz of salt. Water containing a salt concentration of 1 6 (1 + 1 4 sin t) oz/gal flows into the tank at a rate of 8 gal/min, and the mixture in the tank flows out at the same rate. The long-term behavior of the solution is an oscillation about a certain constant level. a) What is this level? b) What is the amplitude of the oscillation? (Round your answers to...
