Comparison of file systems Essays

The following section will consider advantages and limitation of the first two mentioned types of digital forensics: Traditional (dead) and Live computer forensics. TRADITIONAL (DEAD) VS LIVE DIGITAL FORENSICS Traditional (Dead) Forensics In order forensic acquisition to be more reliable it must be performed on computers that have been powered off. This type of forensics is known as ‘traditional’ or 'dead ' forensic acquisition. The whole process of dead acquisition, including search and seizure

is always a good idea to make a complete backup process of the entire system before undertaking any major software change. Along with making a reliable backup, I need you to take this opportunity to save all your metadata down to the file level too before upgrading. In case that there is a disaster, and all of your data has been saved down, then recovery is easy. But if your current metadata has not been saved down to the file level

root is the conventional name of the user who has all rights or permissions (to all files and programs) in all modes (single- or multi-user. The root user can do many things an ordinary user cannot, such as changing the ownership of files and binding to network ports numbered below 1024. The name root may have originated because root is the only user account with permission to modify the root directory of a Unix system. Only a process running as root is allowed to change its user ID to that of another

“Writing is a ticket to a professional opportunity”1(Linville). One cannot have any aspirations of a professional career if they do not at least possess the foundational basics of writing. Love it or hate it, writing is more important to everyday life than most might realize and I have come to learn that the necessity of writing skills continue to grow progressively throughout life. Writing skills have represented the most importance for me from kindergarten to college and eventually in work. I

applications. The kernel is also known as the engine or core of an OS, the outermost part of an operating system that interacts with user commands. Some of the kernel’s tasks are resource allocation, process management, memory management, input/output device management, and security management. It basically mediates access to system resources. The kernel is the vital center of a computer operating system. The service layer acts as a source to resources for application programs such as folder manipulation

Perhaps many are confused about the existing commands linux, this time I will discuss about the linux basic commands used along with examples of its use. 1: Seeing identification (id and group id number) $ Id 2: Looking the calendar date of the system a. Looking at the current date $ Date b. See calendar $ Cal 9 2002 $ Cal -y 3: Seeing the machine identity $ Hostname $ Uname $ Uname -a 4: See who is currently active a. Know anyone who is active $ W $ Who $ Whoami b. Changing finger

Google to synchronize client activity with loosely coupled distributed systems. The principle objective of Chubby is to provide reliability and availability where as providing performance and storage capacity are considered to be optional goals. Before Chubby Google was using ad-hoc for elections, Chubby improved the availability of systems and reduced manual assistance at the time of failure. Chubby cells usually consist of chubby files, directories and servers, which are also known as replicas. These

the logical file system takes to create a file. In order to create a new file, an application calls the logical file system that has all the information about the directory structures. First, the system assigns a new FCB(File Control Block). If the system has already generated some FCBs at file creation time, then it is allocated from a set of available FCBs. Finally, the system responsible for reading correct directory to the memory updates it with the new name of file and FCB and is written back

set(gcf,"position",[1,1,500,500]) Only the position and directions of these features are stored. 2) Enhancement of the features The enhancement of the image depends upon the quality of the input image to ensure the identification and verification system. In our algorithm, we have already taken a good quality of image. 3) Binarize To binarize the image the ridges are denotted by black and furrow are denotted by the white. J=I(1,1,1)>150 imshow(J) set(gcf,"position",[1,1,500,500] 4) Thining The thining

output requests from the S/W, and then translates them into data processing instructions for the central process unit (CPU) and other electronic components of a PC. Application Kernel CPU Memory Devices Actually the kernel is the heart of an operating system. The task of this software is to run the programs and provide secure access to the computer’s hardware. If there are so many programs, and the resources are limited, this software called (kernel) also decides when and how long a program should run

is in one place which is the file server. These machines still have a monitor, motherboard, network card, keyboard and mouse. It loads up the operating system from the network instead of a hard drive. Use of backup The backup is when we take a copy of files or system to store it. There are 3 types of backups and they are the full backup, incremental backup and differential backup. The full backup is where a backup of all files and folder is copied. An incremental backup means where all changes

In elementary school, I read the tale “Sadako and The Thousand Paper Cranes” when my obsession for origami first manifested. In the story, anyone that folds a thousand cranes is granted a wish. Being a gullible child, I was fascinated by this legend and in turn, attempted to fold as many cranes as I could, measuring my hours and days by how many I could create. As I grew older, the moral of the cultural myth has stuck with me. The cranes now are a materialistic representation of the time and effort

Dangers of Social Media Lots of people post on social media about their beliefs right? People post their oppian on the network everyday. Many people get in trouble because they forget that nothing goes away and anyone can look at it. Lots of people don't know that when they apply for a job their social media can be searched or checked. Searching social media can give an insight to people’s personalities. People should be more careful on the internet because social media can be used for employee background

Introduction Surveillance is the monitoring of the behavior, activities, or other changing information, usually of people for the purpose of influencing, managing, directing, or protecting them . An automated surveillance system is a substitution for direct human observation. Artificial intelligence algorithms are commonly used to detect what is being observed. There are several aspects of surveillance, some of which include the following: i. Computer and Network surveillance: Monitoring of data

It loads a 3D model in an ‘.obj file’ format and converts the data from the sensor to a sketch on the microcontroller. The sketch on the UNO gives the data over the UART (Universal Asynchronous Receiver/Transmitter), which is based on the incoming orientation data from the sensor. The

Also upon detecting a malware, Webroot is known to run the scan on the infected system repeatedly until the system is declared clean. Webroot is a very quick install on the system and has the silent install feature as well available in case the install has to be done without the system user’s interaction. Webroot is known to be the smallest and the lightest of all the anti-virus and anti-phishing software products which are available

Lab 5: Fileshares File sharing is the public or private sharing of computer data or space in a network with various levels of access privilege. File sharing allows a number of people to use the same file or use some combinations of being able to read, view, write, full control, read and execute or modify the files. The Read permission allows viewing or accessing of the file contents. The Write permission allows the user to write a file or permits adding of files and subfolders. Read & Execute allows

Endodontic therapy involves treating vital and necrotic dental pulps so that patients can retain their natural teeth in function and esthetics. A successful endodontic therapy depends on many factors,among which the most important step is canal preparation as it determines the efficacy of all subsequent procedures . Cleaning pertains to the sufficient removal of debris, bacteria and smear layer from the root canal.3 Debris is defined as dentin chips and residual vital or necrotic pulp tissue

INTRODUCTION The recent decision of Oracle v. Google by the United States Court of Appeals for the Federal Circuit has posed some severe concern for the Software industry. The decision of the court to grant copyright protection to the Java Application Programme Interface (API) is seen by many as a divergence from the traditional copyright policy of keeping ideas free as the building block of creativity as laid down in Baker v. Seldon over a century ago. What concerns many is the tendency of the
