Give a UNIQUE (NON EXISTING) application/device that involved IMAGE or AUDIO Processing. Define the application and its relevance. Be innovative and creative Ex. Application: Image Duplicate Analyzer Description: It's an application that can be added to an operating system where it avoids duplication of images in a single directory (folder). It uses image processing to check multiple images for duplicates instead of using file name. This will help to detect duplicates of image files much effective which will save more memory spaces. This application works the same as the current process, the only difference is it analyzes the files by image not by file name.

A disk attribute in Windows XP that is hidden from view in Disk Management is

Partitions on a hard disk must utilize the same filesystem once one is formatted with it. Is it right or wrong?

True/false: 1. One of the I/O module functions is command decoding 2. With multiple zoned recording, the amount of data that can be stored on the outer long track is the same as that can be stored on the inner short tracks, 3. Using Winchester head mechanism, the head is in a physical contact with the disk surface when it is in motion. 4. Scanning information at the same rate by rotating the disk at a fixed speed is known as the constant angular velocity. 5. The disadvantage of the software poll is that it is time consuming 6. When large volumes of data are to be moved, the most efficient technique is direct memory access (DMA). 7. In semiconductor memory, soft errors are permanent. 8. File organization on disk has no effect on I/O performance. 9. DRAMs are more densę than SRAMs 10 The areas between pits are called lands

Flash storage: How is the flash translation table, which is used to map logical page numbers to physical page numbers, created in memory?

Get-OSVersion - Write a PowerShell function called Get-OSVersion that returns the numeric version of the operating system The function should take an input parameter called ComputerName which is the name of the computer system from which to get the OS Version • The function should gather the required information from the Win32 ComputerSystem class in WMI • The function should output a string stating the OS version on the computer inspected

linux !#bin/bash Backup Files Write a bash script to backup files. The script can take 0, 1 or 2 arguments. When there are 0 or more than 2 arguments, the script should print out the usage of the program on the screen. When there is 1 argument, the program should take the argument as source directory and backup all the files (not include directories) in the source directory. If the source directory does not exist, the program should print out the error message and the usage of the program on the screen. If the source directory exist, create a subdirectory inside source directory named ”backup-yyyy-mm-dd” and copy all the files in source

At a murder scene, you have started making an image of a computer’s drive. You’re in the back bedroom of the house, and a small fire has started in the kitchen. If the fire can’t be extinguished, you have only a few minutes to acquire data from a 10 GB hard disk. Write one to two pages outlining your options for preserving the data.
