Google File Systems (GFS) is developed by Google to meet the rapidly growing demand of Google’s data processing needs. On the other hand, Hadoop Distributed File Systems (HDFS) developed by Yahoo and updated by Apache is an open source framework for the usage of different clients with different needs. Though Google File Systems (GFS) and Hadoop Distributed File Systems (GFS) are the distributed file systems developed by different vendors, they have been designed to meet the following goals: They
Alternatives of Network File System Since human beings have used Computers , the request of being rich ,and getting more information quicker than before has increased . Have you ever found yourself rushing from one computer to another in your office or home ,attending to several different jobs at various location? Or do you often find yourself moving files that need printing from a PC that you happen to be working on the PC that is Connected to the printer ? You may have heard a lot about
1. Introduction A penetration test is performed on a system in order to find security threats. The pen tester carries out the same tests a hacker would do. The hacker is looking for vulnerabilities in the computer and network in order to exploit them and gain access. The pen tester performs the same task but wants to find and fix any security threats without harming or compromising the system. The pen tester has permission to perform vulnerability checkes wheras the hacker does not. (Add more).
and in particular, file extensions, viruses, social networking safety and protecting your online identity. 1. A.) A File extension is the suffix placed at the end of a filename, that is used to make it identifiable, what format of content is held in a file. File extensions were initially designed to help users to determine which application to launch in order to run a program, yet, sneaky sly's have used them to implement rouge files, and virus into innocent peoples computer systems. Always be wary
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

Because then, passwd and shadow files won’t be accessible via the local user. Chapter 5 Conclusion In this report, Add-on security in firefox was analyzed by practical implementation of addons in javascript and XUL. These addons were successfully able to bypass firefox’s

For good system analyst skills required are 1. The ability to learn quickly. 2. Logical approach to problem solving. 3. Knowledge of Visual Basics, C++ and Java. b)
Linux is an operating system developed by Linus Benedicts Torvalds. The operation system is the key of communication between the software and the hardware. Linux is a free and open-source software1 built around the Linux kernel. The first event leading to its creation is the conception of the UNIX operating system implemented by Ken Thomson and Dennis Ritchie in 1969 and first released in 1970. They rewrote it to make it portable and it became widely adopted, copied and modified by academic institutions
Containers - Drives - Files APPENDIX .: I. INTRO :. [-=] About [=-] This is a quick rundown on how to encrypt files, containers, and drives under Linux. The use of loopback encrypted filesystems and openssl is explained and examples are given. This paper should have you encrypting in no time. The following commands were done running kernel 2.6.9. .: ENCRYPTING :. I'll outline how to create encrypted containers and drives using the loopback filesystem support and file encryption via openssl
workflow emphasize the importance of using a system to handle the many programs and the data files that are a standard part of a research project. Files may be developed, used, and updated by multiple members of a research team. Therefore, it is imperative that members of the team agree on a set of guidelines for naming, revising, and storing files. In the earlier example of documentation, the initial comment of a program file included who prepared the file and when it was last updated. This is good
Advantages and Disadvantages of ICT ICT has made my project easier to do. Making a catalogue is a long process, involving a lot of design and research plans, using a computer and IT based materials has cut down the time it would take of I had done it manually. For example, before starting to make my catalogue I had to do some research on the items I wanted to advertise, using the internet was a faster more efficient way of doing this. The internet showed the websites I needed to go
paper is to analyze the security of UNIX. Considerations shall be given regarding generalized security aspects of a typical UNIX system. The ultimate scope of the following presentation shall remain within the boundaries of a few of the more critical UNIX security aspects. Of particular note will be discussion regarding standard user access, root access, file system security, and internet access precautions. This will not focus on specific measures used to implement security, but rather will investigate

Explain the purpose of operating systems (P2) The operating system whatever it may be (Windows or Linux) it is the most important program that runs on a computer. All general purpose computers require an operating system in order to run other programs. The Operating system performs essential basic tasks such as recognizing input from the keyboard, keeping track of files and their directories on the disk, the sending output to the display screen and the controlling of peripheral devices such as keyboards
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. The MFT
This paper proposes the Google File System (GFS). They introduced GFS to handle Google's massive data processing needs. GFS considers the following goals: higher performance, scalability, reliability and availability. However, it's not easy to reach these goals, there are many obstacles. Thus, in order to tackle challenges, they have considered using constant monitoring, error detection, fault tolerance, and automatic recover to tackle component failures that can affect the system's reliability and
1.1 Describe Systems and Procedures for Storing and Retrieving Information Collect documents to be filed, sort in to alphabetical, numerical or chronological order, find the relevant file and place the document inside after it’s divider, and return the file to its original place. Confidential files should be kept in a lockable cabinet and old documents should be shredded after the length of time outlined by the organisation. Electronic filing is similar but on the computer. It is important to name
Google File System (GFS) was developed at Google to meet the high data processing needs. Hadoop’s Distributed File System (HDFS) was originally developed by Yahoo.Inc but it is maintained as an open source by Apache Software Foundation. HDFS was built based on Google’s GFS and Map Reduce. As the internet data was rapidly increasing there was a need to store the large data coming so Google developed a distributed file system called GFS and HDFS was developed to meet the different client needs. These
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 forensic to investigate these offenses. Actually, computer crimes are governed by specific laws and dealt
