Given that the company "Slate Rock and Gravel" has business locations in Granitetown and Bedrock, suppose that the company has been assigned a large block of consecutive IP addresses starting with 192.172.0.0, and that it wishes to set up two subnets, one for each location, with each subnet having sufficient IP numbers assigned to cover the host computers at that location. The IP addresses must be assigned in this order: first to Granitetown, and then to Bedrock. Assume that there are 4,000 computers in Granitetown and 2,000 in Bedrock.
Your task is to assign IP address to the two locations. You must show your steps for each calculation.

It is well known that the thermal efficiency of heat engines increases as the temperature of the energy source increases. In an attempt to improve the efficiency of a power plant, somebody suggests transferring heat from the available energy source to a higher-temperature medium by a heat pump before energy is supplied to the power plant. What do you think of this suggestion? Explain.

A college course may have one or more scheduled sections, or may not have a scheduled section. Attributes of Course include courseID, courseName, and units. Attributes of Section include sectionNbr and semester. The value of sectionNbr is an integer, which distinguished one section from another for the same course, but does not uniquely identify a section. There is an operation called findNumSections, which finds the number of sections offered for a given course in a given semester.

A large retail organization previously divided work among its four employee-benefits staff into distinct specializations. One person answered all questions about superannuation (pension plans), another answered all questions about various forms of paid time-off (e. g., vacations), and so on. These jobs were recently restructured so that each employee-benefits person answers all questions for people in a particular geographic area. One staff member is responsible for all employee-benefits inquiries from anyone in a particular geographic region.
