File system Essays

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

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

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

“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

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

for privacy and permission. BYOD • Operating systems-The software that supports a computer's most simple functions, such as scheduling tasks and controlling external systems eg. Printer, mouse. • Application software-Application software is different computer programs designed to allow the user to be able to perform tasks and activities. • File management-A file manager is a computer program that allows a user to manage their personal and shared files and folders. • Storage devices-A piece of equipment

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

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

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

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

inferred to be inversely varying with the quality of information technology system in a country. (Bagchi, 2006) Countries with better equipped computing systems and environment are shown to have lower piracy rates than those with poorly equipped systems. This information technology system includes the internet. The internet is often viewed as the main driving force for the increase of digital piracy rates as it made file sharing much easier and readily available. In fact, five of the six most common

The Web 2.0 has revolutionized business practice and the cross-platform iTunes functionality is one of the representatives by selling music with DRM-free. Apple has removed the Fairplay Digital Rights Management system from iTunes music in order to create a larger iTunes user base and protect its integrated platform. This action also enables Apple to protect the corporate knowledge on user interfaces and industrial design. Nevertheless, this refusal was meet some criticisms which claimed that the

Internet Piracy gives people access to media without having them pay and allows them the comfort of just downloading a file or even streaming from the internet.Piracy is considered by most as morally wrong and degrading the quality and reputation of certain intellectual properties. Internet piracy is an immoral act which has been thought of as equal to stealing.People

All members of the Recording Industry Association of America (RIAA) are also the plaintiffs. A&M Records claimed that Napster could be held liable for contributory infringement and vicarious infringement of copyrights based on their peer-to-peer file-sharing service. The district court agreed. Napster was given a preliminary injunction by the district court that “enjoined them from engaging in, or facilitating others in copying, downloading, uploading, transmitting, or distributing plaintiffs’

There have been significant technological advancements over the past two decades, changing the way music is recorded and distributed. With the rise in popularity of the internet and the introduction of MP3 players into the market, consumers have been given a vast number of choices to obtain music - from purchasing a physical copy, to legally or illegally downloading, and streaming online – giving rise to issues that make it increasingly difficult for record labels and artists to create and maintain

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

works. Through past cases, important precedencies have been established. Napster Developed by programmers Sean Fanning and Sean Parker in 1999, Napster was a website that used peer-to-peer (P2P) sharing to allowed users to trade copyrighted music files stored on Napster’s servers without any payment necessary. P2P networks enable computers to connect directly to each other and utilize specialized

development and commercialization of internet allowed people to freely download or upload music as digital file online. This act, also known as music piracy, created an option that allows consumers to listen to music other than purchasing artists’ albums. And when carrying this action out, consumers justify their action by criticizing the inflated music market. Consumers consider downloading illegal files online as “a revolt against over-priced and inferior products” states Harlan Spotts, the writer of “We'd
