...Template Hands on project 4-4: Answer: Case Project 4-5 Answer: To acquire the data from the source file following methods can be used: 1. Disk-to-Image files: FKT Imager can be used to disk-to-image files from other proprietary formats. We need not segment the data as entire 2 GB can be stored directly. FKT runs on the windows and needs write blocking device. FKT can read AccessData, Expert Witness, SafeBack, SMART and raw format files, CD and DVD files. Proprietary format tools run an option to compress or not compress image files of a source drive, to save space on the target drive. Hashing helps check the integrity of the data. Various tools can integrate metadata into the image file But there exits an inability to share an image between different vendors’ computer forensics analysis tools. Like ILook imaging tool IXimager produces IDIF, IRBF, and IEIF but can be read only by ILook. Proprietary format tools produce a segmented file of 650 MB. Maximum file size per segment can be 2 GB. 2. Disk-to-disk copy: UNIX/Linux dd command does disk-to-disk copy. dd command is very easy and effective in a Linux machine. But for that we need equal or larger space in the target disk to copy full image from the source disk. Raw formatting is a technique in which we use dd command to generate image files which are split into smaller segments and are exact bit-by-bit replica of the original disk. These are sequential flat files of the source drive. Hardware and software...

...S. Park and S.-Y. Ohm: New Techniques for Real-Time FAT File System in Mobile Multimedia Devices 1 New Techniques for Real-Time FAT File System in Mobile Multimedia Devices Sunhwa Park and Seong-Young Ohm Abstract — Flash memory has become the most important storage media in the mobile multimedia products such as MP3 players, mobile phones, and digital cameras. Most mobile multimedia devices, however, use one of the conventional FAT file systems slightly modified for flash memory environments. Our analysis shows that theses file systems have some restriction in recording a live multimedia stream stably because they have irregular write response times. In this paper, we have considered the problems of the existing FAT file system and propose two new techniques to solve the problems. The first technique called Sector Reservation method reduces internal overhead effectively. And the other method called ACPA avoids the periodic cluster allocation of the conventional FAT file system and removes the frequent modifications on the file allocation table in the FAT file system. To evaluate our new techniques, we implemented a prototype Real-Time FAT file system on ARM9 board with our two novel techniques. The experimental results show that our system achieves our goal successfully in that its write response times are very deterministic and more uniform1. Index Terms — Flash memory, FAT file system, FTL, Mobile multimedia device. I. INTRODUCTION One of the distinct trends in...

...ITM301 Module 1 Module 1 – Case Click Link Below To Buy: http://hwcampus.com/shop/acc201-module-1-case/ Data, Information, and Organizational Knowledge Assignment Overview Every company has, to a greater or lesser extent, an information subsystem -- that is, a means by which it gathers data, interprets it, and makes it available to employees through a distribution system. Whether we are talking about marketing information, cost projections, accounting results, or internal quality reports, every company depends on knowledge to support its planning, decision-making, and control. So how does knowledge fit into the picture? The emergence of the field called knowledge management has highlighted some key propositions in the last 10 years or so. All organizations are storehouses of knowledge that operate in information-rich environments made up of people and things both inside and outside the organization itself Organizations organize, interpret, and evaluate this information to solve organizational problems Knowledge is the primary mechanism for processing and utilizing information People's brains are the key knowledge resource of any organization Codified knowledge stored in books, audio, videotapes, and computer systems can be an important knowledge resource as well There are organizational processes and strategies for IT management and management in general. Therefore, processes and strategies in particular can significantly enhance the ability of organizations to...

It is capable of this level of efficiency because it uses the connectionless User Datagram Protocol (UDP) for communication rather than the acknowledgement-based Transmission Control Protocol (TCP). 4. b T1 is a time indicator that corresponds to 50% of the DHCP lease time; T2 corresponds to 87.5% of the total DHCP lease time. 5. b A DHCP server will hand out IP addresses to requesting clients from its available address pool, which consists of the total address range less any IP addresses that have been configured as exclusions from the available range. 6. c The TFTP protocol was used by BOOTP, the predecessor to DHCP, which was used to provide automatic IP addressing information to diskless workstations. 7. c When you reconcile a server or a scope, the DHCP service uses both the summary information in the registry and the detailed information in the DHCP database to reconstruct the most current view of the DHCP service. 8. c Superscopes contain only a list of member scopes...

...Part 1 1. What is the difference between interactive processing and real-time processing? Interactive processing is when there is a continuous exchange of information between the computer and user whilst performing tasks. Examples include entering information into a query in a database or information into a word processor. Real time processing means that there is a continual input, process and output of data. It may be a situation whereby a user sends in transactions and awaits a response from a distant computer before continuing. We see this happening when we use telephone banking to transfer funds from our savings to our credit card and the money is accessible immediately. Real Time Processing [Online]. Available from http://www.answers.com/topic/real-time-processing-e-business-term. (Access 14 July 2010). Interactive Processing [Online]. Available from: http://linux.about.com/cs/linux101/g/interactiveproc.htm. (Accessed 14 July 2010). 2. What complications could arise in a time-sharing system if two processes require access to the same file at the same time? Are there cases in which the file manager should grant such requests? Are there cases in which the file manager should deny such requests? If two processes require access to the same file at the same time, two main situations could arise: 1. Both processes attempt to read the file in which there is no harm. If the file is used as merely input for the processes and is not being changed then...
