Structure of NTFS The NTFS file system is used in all critical Microsoft Windows systems. It is an advanced file system that makes it different from the UNIX file systems that the original TCT was designed for. This document gives a quick overview of NTFS and how it was implemented. The biggest difference is the use of Alternate Data Streams (ADS) when specifying a meta data structure. MFT The Master File Table (MFT) contains entries that describe all system files, user files, and directories.
File system Concept A file is collection of related information recorded on secondary storage by sequence of bits, bytes, lines or records. All data written to secondary storage in file format, which can be numeric, alphabetic, alphanumeric or binary. Attributes of files: - name to which system refers when file participates in process; - file identifier; - file type ( text, source, object, executable); - location; - size; - protection level; - creation / modification date. Operations with files:
Data Acquisition Data acquisition is the process of copying data. For computer forensics, it’s the task of collecting digital evidence from electronic media. There are two types of data acquisition: static acquisitions and live acquisitions. Static Acquisitions: if you have preserved the original media, making a second static acquisition should produce the same results. The data on the original disk is not altered, no matter how many times an acquisition is done. Your goal when acquiring data for
Have you ever needed to have more than one home computer for you and your family? Do you have two or more computers, but need to copy and/or share files and/or programs between them, but you don’t know how? Do all of your computers need Internet access, but you don’t want to have a phone line installed for each of them? Well, you can do all of this. I know, because this is what I did at my home. After doing research I found that there are several advantages for having your own Home Computer Network

Windows 2000 Server will be able to support up to four processors. Windows 2000 Advanced Server will support up to eight processors. And Windows
be using. With Windows XP/2000 there are two file system types to choose from, FAT and NTFS. FAT is an acronym for file allocation table, and NTFS is an acronym for New Technology File System. Windows XP also supports two types of file systems on CD-ROM and DVD (Compact Disc File systems [CDFS] and Universal Disk Format [UDF]). Primarily the Windows XP/2000operating system uses the NTFS file system. The NTFS file system uses the cluster scheme that is seen in FAT for allocating data, but for a given
Computer Forensic Tools: The use of computers in homes, schools, offices, and other places has increased in the past few years due to technological developments. As computers have become important components of modern communication, their increased use has also led to the emergence of computer crimes. Computer crimes basically involve the use of a computer system to carry out an illegal activity. In attempts to lessen the frequency and impact of computer crimes, law enforcement agencies use computer
? Abstract?Digital forensic investigations has become an important field in this era due to the raise of cybercrimes. Therefore, most governments and companies found the urgent need to invest more in research related to digital forensic investigations. To perform digital forensic investigations covering extraction, analysis, and reporting of digital evidences, new methods and techniques are required. One of these methods used when applying digital forensics on a Windows operating system, is PowerShell
My advice to someone starting his or her coop would be to start as soon as possible. 150 or 250 hours is a long time, especially if you already have another job. This coop led to two and a half months of a very busy and hectic schedule. It is a very important part of the learning process and I don’t recommend rushing it. In my case I found it a difficult task remembering where I was supposed to be on a certain day, so I bought myself a day planner. I also advise future students starting their coops

If NTFS is employed users will receive a prompt to format the drive when attempting to access content. Users will find that there are some reductions in performance and should generally expect a computer performance drop of at least single digit percentages
Q.1 a) What is meant by operating system? Define it in detail with the help of suitable examples. Answer: The 1960's meaning of an Operating system is "the programming that controls the Hardware". Not with standing, today, because of microcode we require an improved definition. We see an operating system as the program that make the equipment usable. In short, an operating system is the set of programs that controls a computer. A few illustrations of operating systems are UNIX, Mach, MS-DOS, MS-Windows
Data recovery programs are a boon to those who have lost their data due to some reason that we do not want to know now. All that matters is the deleted data to be retrieved somehow and that’s it. Whether the drive is damaged in error, data lost while formatting, files deleted by accident, due to software crash or ran it through a wash, all you want is your data back. But fret not, as the data that you might have recently deleted and then further cleared from the Recycle Bin are usually still found
Manager, Windows Explorer etc. The files are placed in the folders and the index contains the file information known as File Allocation Table (FAT). One of the latest file management systems of the Windows is the New Technology File System (NTFS). The NTFS store owner name, it provides POSIX file permissions, creation timestamps, last access timestamp, and last content modification timestamp. The Mac operating system uses the file managers that include: the Disk Order, Finder, Path Finder, and
some high traffic sites are using MySQL so there is no doubt on performance of PHP’s preferred database management system i.e. MySQL (by Oracle). • The ext4 file system of Linux OS (supports PHP) has better performance record than MS Windows OS’s NTFS (used for ASP) during Input/output (IO) process. • The Linux web servers with LAMP platform use comparatively fewer server resources i.e. CPU and Memory. • The PHP developers got the flexibility choose their own editor but this feature is not associated
1. Introduction The aim of this report is to theoretical cover data preservation, examination of digital evidence, tools and techniques for data capture, preservation and examination with a list of recommendations. In our modern society, computers and other digital devices are becoming ubiquitous. In the late 1970’s the number of crimes that involved digital devices and computers has been increasing rapidly. As a result of that, computer experts specified the need for permanently improving digital
An Operating system is system software that controls the system’s hardware that interacts with users and the application software. As we all may know, Windows Microsoft has always been a commercial high-level sale in the retail industry and an in domain operating system used today. But there are more operating systems than just Windows Microsoft than the general population may assume. Linux is another well-known operating systems, which is free and open-source software. Linux is also used in companies
Windows uses the “New Technology Filing System” or NTFS. This filing system was introduced and included with every version of Windows since 1993. It has many useful features like encryption, permissions and better support for larger disks. Mac OSX in the other hand uses HFS+ as their filing system for all
UNIX VS NT To build a good and stable network is extremely difficult. It takes a team of very knowledgeable engineers to put together a system that will provide the best service and will forfill the need for the companies users and clients. There are many issues that have to be resolved and many choices have to be made. The toughest choices IT managers have to make, are what will be the best server platform for their environment. Many questions must be answered. Which server software offers complete
Introduction Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. But it also contains highly organized physical structures which are called intracellular organelles. These organelles are important for cellular function. For instance Mitochondria is the one of most important organelle of the cell. Without
. Ten years later, there was a separate child pornography task force in half of all FBI offices; many other law enforcement agencies also operated their own task forces. This “new” violation resulted in the seizure of ever-increasing volumes of digital evidence and was a major driver in the growth of digital forensics" (Pollitt 9). Quickly, organized crime began to realize the potential of computers (and the internet) as well. The terrorists involved in the 9-11 attacks were using computers with
