The administrators of Tiny College are so pleased with your design and implementation of their student registra- tion and tracki

ng system that they want you to expand the design to include the database for their motor vehicle pool. A brief description of operations follows:
* Faculty members may use the vehicles owned by Tiny College for officially sanctioned travel. For example, the vehicles may be used by faculty members to travel to off-campus learning centers, to travel to locations at which research papers are presented, to transport students to officially sanctioned locations, and to travel for public service purposes. The vehicles used for such purposes are managed by Tiny College’s Travel Far But Slowly (TFBS) Center.

* Using reservation forms, each department can reserve vehicles for its faculty, who are responsible for filling out the appropriate trip completion form at the end of a trip. The reservation form includes the expected departure date, vehicle type required, destination, and name of the authorized faculty member. The faculty member who picks up a vehicle must sign a checkout form to log out the vehicle and pick up a trip comple- tion form. (The TFBS employee who releases the vehicle for use also signs the checkout form.) The faculty member’s trip completion form includes the faculty member’s identification code, the vehicle’s identifica- tion, the odometer readings at the start and end of the trip, maintenance complaints (if any), gallons of fuel purchased (if any), and the Tiny College credit card number used to pay for the fuel. If fuel is purchased, the credit card receipt must be stapled to the trip completion form. Upon receipt of the trip completion form, the faculty member’s department is billed at a mileage rate based on the vehicle type used: sedan, station wagon, panel truck, minivan, or minibus. (Hint: Do not use more entities than are necessary. Remember the difference between attributes and entities!)

* All vehicle maintenance is performed by TFBS. Each time a vehicle requires maintenance, a maintenance log entry is completed on a prenumbered maintenance log form. The maintenance log form includes the vehicle identification, a brief description of the type of maintenance required, the initial log entry date, the date the maintenance was completed, and the name of the mechanic who released the vehicle back into service. (Only mechanics who have an inspection authorization may release a vehicle back into service.)

* As soon as the log form has been initiated, the log form’s number is transferred to a maintenance detail form; the log form’s number is also forwarded to the parts department manager, who fills out a parts usage form on which the maintenance log number is recorded. The maintenance detail form contains separate lines for each maintenance item performed, for the parts used, and for identification of the mechanic who performed the maintenance. When all maintenance items have been completed, the maintenance detail form is stapled to the maintenance log form, the maintenance log form’s completion date is filled out, and the mechanic who releases the vehicle back into service signs the form. The stapled forms are then filed, to be used later as the source for various maintenance reports.

* TFBS maintains a parts inventory, including oil, oil filters, air filters, and belts of various types. The parts inventory is checked daily to monitor parts usage and to reorder parts that reach the "minimum quantity on hand" level. To track parts usage, the parts manager requires each mechanic to sign out the parts that are used to perform each vehicle’s maintenance; the parts manager records the maintenance log number under which the part is used.

* Each month TFBS issues a set of reports. The reports include the mileage driven by vehicle, by department, and by faculty members within a department. In addition, various revenue reports are generated by vehicle and department. A detailed parts usage report is also filed each month. Finally, a vehicle maintenance summary is created each month.

Given that brief summary of operations, draw the appropriate (and fully labeled) ERD. Use the Crow’s foot methodology to indicate entities, relationships, connectivities, and participations.

Suppose that a 64MB system memory is built from 64 1MB RAM chips. How many address lines are needed to select one of the memory
alexdok [17]

Answer:

6 address lines

Explanation:

The computation of the number of address lines needed is shown below:

Given that

Total memory = 64MB

= 2^6MB

=2^{26} bytes

Also we know that in 1MB RAM the number of chips is 6

So, the number of address lines is 2^{26} address i..e 26 address lines

And, the size of one chip is equivalent to 1 MB i.e. 2^{20} bytes

For a single 1MB chips of RAM, the number of address lines is

\frac{2^{26}}{2^{20}} \\\\= 2^6 address

Therefore 6 address lines needed
