3. I/O Management: Disk Arm Scheduling & RAIDa. It is known that a disk drive has 256 cylinders, with cylinder numbers starting from 0 and ending at 255. The position of the needle on the disk drive currently stops at 128. It is also known that the needle always “goes to the cylinder with the smaller number first”. The order of the positions visited sequentially is: 254, 64, 32, 100, 50, 70. From the 3 choices of algorithms below, which one is the best algorithm? Make each image and determine the seektime.i. SCANii. C-SCANiii. FIFO
Select problem below. Your post must include: The problem statement. A description of your solution highlighting the use of the split(), join(), lists and the different list operations involved in solving the problems. Include line numbers from your program. please make it simple and DONT use Java Create a program and reads a MAC address and determines whether it is syntactically correct or not. Assume the format of the MAC address is dd-dd-dd-dd-dd-dd where dd represents a 2-character hexadecimal number (each character is a digit or a letter between a and f). Use the `split function to access the values in the input MAC address.

1:56 Suppose that the majority of students use Linux most of the time but they still need access to Windows for those few applications that they haven't found acceptable alternatives for in Linux. Students also use MS Office at University and want to have access to it at home. Other students want to have access to the altemative operating system just for fun, training, or to keep current in their studies. Identify how to managing (set-up) dual boot operating systems (e.g, RedHat and Windows) on a single computer system.

Student information is being held in a data area, where each student record has the following format: The first nine bytes are the student number, held in ASCII The next byte is the course mark The next word is the section identifier There are well over three hundred such student records that have been loaded sequentially into memory starting at address $10000. The last record loaded is a dummy record with a section identifier of $FFFF, to show the end of the records. If a2 has the address of a student record, what is the location of the next record in the array / data area:
