A disk system has 250 cylinders, numbered 300 to 550. Assume that the read / write head is at cylinder 400 and determine the order of head movement for each algorithm to satisfy the following stream of
requests. For comparison purposes, calculate the total head travel distance. They are listed in the order
received.
450, 510, 345, 410, 545, 330, 495, 395, 475, 380, 529, 251, 365
Discuss the following algorithms and briefly explain which algorithm is best. (i) LOOK, (ii) SSTF, (iii)
C-SCAN, (iv) FCFS.

Which of the following methods could be considered a “best practice” in terms of informing respondents how their answers to an on-line survey about personal information will be protected? respondents are informed that investigators will try to keep their participation confidential; however, confidentiality cannot be assured. respondents are informed that a research assistant will transfer all the research data to a password-protected computer that is not connected to the internet, via a usb flashdrive. the computer is located in a research team member’s office. the investigator uses the informed consent process to explain her institution’s method for guaranteeing absolute confidentiality of research data. the investigator uses the informed consent process to explain how respondent data will be transmitted from the website to his encrypted database without ever recording respondents’ ip addresses, but explains that on the internet confidentiality cannot be absolutely guaranteed.

In my email i got a message it says a quick message and in message details on who its from its says nicole and under nicole is [email protected] -

Monica and her team have implemented is successfully in an organization. what factor leads to successful is implementation? good between different departments in an organization leads to successful is implementation.
