The Linux file system does things a lot more differently than the Windows file system. For starters, there is only a single hierarchal directory structure. Everything starts from the root directory, represented by '/', and then expands into sub-directories. Where DOS/Windows had various partitions and then directories under those partitions, Linux places all the partitions under the root directory by 'mounting' them under specific directories. Closest to root under Windows would be c:. Under
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 .

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
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
The operating system (OS) is a collection of software to control the computer tasks and manage proper utilization of the hardware resources. The basic operating systems are the Linux, UNIX, Mac and Microsoft Windows. There are several and diverse components of an operating system that include but not limited to the file management, security, memory and process management. The following paragraphs present the comparison of basic operating systems with respect to the above given features (Solomon
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:
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
OF LEGACY DATABASE SYSTEMS: Definition of Legacy System: In the context of computing, the legacy system refers to the programming languages, application software’s and outdated computer systems. The legacy systems may also be linked to the terminology and processes that are no longer applicable to the current contexts, thus creating confusion. In theory, it would be best to have access to use the latest technology. But in the reality, most of the organizations have legacy systems, to some extent. In

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).
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
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
you have only one chance to create a reliable copy of disk evidence with a data acquisition tool. Live acquisition: The future of data acquisitions is shifting toward live acquisitions because of the use of disk encryption with newer operating systems (OSs). In addition to encryption concerns, collecting any data that’s active in a suspect’s computer RAM is becoming more important to digital investigations. The processes and data integrity requirements for static and live acquisitions are the same
Problems & Strategies of Information Keeping & Management Keeping Every human keeps or stores information. Some keep their information organized, others not. People encounter huge amounts of information daily, too much to store it all. There are various costs that prevent us from storing all the information we receive. The more information we keep, the more management is required to keep all the information organised. Information needs to be organised so that people can obtain value from it. As
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 on the Hard Drives

attractive form. Filing systems are important to any secretary. The files at any office must be maintained in perfect order, so that any file may be located promptly by any person authorized to use the files. General secretaries often work inside an organization where company records are maintained by special file clerks inside a central filing room, but the secretary may still remain responsible for all the filing. A secretary must learn the rules of four basic filing systems. The alphabetic, subject
database and fileservers are Linux servers. Linux is a UNIX system which implies that it has solid compatibility, stability and security features. Linux is used for the mentioned environments because these services require high security. Further, an increase of attacks on these servers can be observed. Additionally, the methods to prevent intrusions on Linux machines are insufficient. Further, the analysis of incidents on Linux systems are not considered appropriately (Choi, Savoldi, Gubian, Lee
delete a couple of files or a complete directory accidentally, of course, and it will be the job of the LAN administrator to save the day because the files were the company's financial statements and they are due in a meeting yesterday. The NetWare 3.12 and 4.X SALVAGE utility is the extremely useful and sophisticated tool to recover these files. NetWare retains deleted files in the volume were the files originally resided. There they continue to pile up until the deleted files completely saturate
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
