Nt1310 Unit 4.1 Term Paper

“In 2003, two students from MIT bought 158 used and formatted disk drives from a wide variety of locations. From there they were able to extract over 5,000 credit card numbers, secret corporate financial information, detailed personal and medical information, along with many gigabytes of personal emails and pornography” (Sherweb, 2010, para 2). Computer forensic tools are used to find out and analyzing available, deleted, or hidden information that may be used for evidence in a legal matter. These forensic tools allows the user to uncover potential evidence that someone else does not want to be discovered. This

the following is true about the process of read data, as described in the chapter?

The host writes a byte of data into the data-out register, and sets the write bit in the command register

1. Consider a processor that supports virtual memory. It has a virtually indexed physically tagged cache, TLB, and page table in memory. Explain what happens in such a processor from the time the CPU generates a virtual address to the point where the referenced memory contents are available to the processor.

Q: Which of the following allows certain hardware subsystems within the computer to access system memory independently of the central processing unit?

b).1. Instruction and data transfers would take three bus cycles each, one for the address and two for the data. Since If the address bus is 32 bits, the whole address can be transferred to memory at once.

Computers organize memory with master map. They do know ‘where’ the information which they need is.

a.|Each program to be processed was loaded into secondary storage, then swapped into memory in parts|

In computer organization and architecture, memory is the most important part of a computer. Every computer must have its own memory. Memory represents two stable or semi-stable states that are representing 1 and 0. It is capable of being written to at least once and read multiple times. In this lab, we will learn briefly on two parts of memory only, which are RAM and ROM. As we know that a memory can either be non-volatile (as seen in a read-only memory) or volatile (used in random access memory).

Digital forensics has been responsible for putting away thousands and thousands of criminals. Ranging from simple crime computer crimes to child pornography. To get quality evidence that can be admissible in court there are steps that are needed in preparing a computer investigation. There are also requirements for data recovery, as well as procedures for corporate investigations. “Digital forensics has become prevalent because law enforcement recognizes that modern day life includes a variety of digital devices that can be exploited for criminal activity, not just computer systems. While computer forensics tends to focus on specific methods for extracting evidence from a particular platform, digital forensics must be modeled such that it can encompass all types of digital devices, including future digital technologies” (Reith, Carr, and Gunsch, 2002).

Development of this technical evaluation report is the result of a request from a standing Army CPT to fulfill the requirement of expanding the CPTs memory forensics capabilities. The three considerations of cost, capability, and operating systems compatibility are the main points for comparison. The memory forensic tools where compared and contrasted based upon the guidelines that the CPT provided. When comparing the two tools in all three factors of consideration Magnet IEF was the clear winner. The final recommendation of this technical evaluation is that the CPT acquires Magnet

In today’s world it is an indisputable fact that computers and digital devices are a part of our everyday lives. As such they are a part of our society whether they are used for business or for personal reasons. There are many uses for computers. We can

Explanation: E) The "flow of control" describes the order of execution of instructions. It defaults to being linear (or sequential) but is altered by using control statements like conditionals and loops.

There are a few advantages of the forensic methodology regarding mobile forensics. One of the advantages is the ability to search a digital device that 64% of Americans utilize on a daily basis. As a result, this media permits forensic examiners to acquire, analyze, and examine texts, emails, phone calls, images, and internet history. Also, since current smartphones are heavily employed for GPS, location tracking is also possible. Additionally, there have been advances in forensic tools that are exclusive for mobile forensics that were developed by companies like Cellebrite and MSAB (XRY tool).

In the data extraction phase, the data is extracted and prepared for further processing. The resume
