On a traditional magnetic hard disk drive with 200 cylinders (numbered 0 - 199), a file transfer requires access to the cylinders in the following fashion: 116, 22, 3, 11, 75, 185, 11, 87 Draw the head travel sequence in the order of cylinders covered for FCFS, SSTE, SCAN. C-SCAN, LOOK and C-LOOK algorithms in order to answer the below questions. Assume that the head is over cylinder 88 at the start, and is moving upward through the cylinders towards the last cylinder 199? The head assembly flyback time is 20 cylinders. What is the total cylinder travel for C-LOOK algorithm? (write only the number)

Much has been made of the new web 2.0 phenomenon, including social networking sites and user-created mash-ups. how does web 2.0 change security for the internet? how do secure software development concepts support protecting applications?

In this lab, you complete a python program that calculates an employee's annual bonus. input is an employee's first name, last name, salary, and numeric performance rating. if the rating is 1, 2, or 3, the bonus rate used is .25, .15, or .1 respectively. if the rating is 4 or higher, the rate is 0. the employee bonus is calculated by multiplying the bonus rate by the annual salary.

Given a link with a maximum transmission rate of 32.8 mbps. only two computers, x and y, wish to transmit starting at time t = 0 seconds. computer x sends filex (4 mib) and computer y sends filey (244 kib), both starting at time t = 0. statistical multiplexing is used, with details as follows packet payload size = 1000 bytes packet header size = 24 bytes (overhead) ignore processing and queueing delays assume partial packets (packets consisting of less than 1000 bytes of data) are padded so that they are the same size as full packets. assume continuous alternating-packet transmission. computer x gets the transmission medium first. at what time (t = ? ) would filey finish transmitting? give answer in milliseconds, without units, and round to one decimal places (e.g. for an answer of 0.013777 seconds you would enter "13.8" without the quotes)
