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

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

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
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
better secure your system. We will discuss the following four (4) areas: v Email v Internet v Chat Programs v Virus Protection 1. Email: · Do not open any email attachment that you receive from anyone without checking first - not even from your closest friends. · If someone has to send you a doc file ask them to convert it into *.rtf or *.txt format and then send. · If you must open any doc extension files, you can first use one of those doc file readers available free
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
Memory management is basically the functionality of computer which runs main memory. It keeps track of each and every memory location either it is allocated to some process or it is free. It checks how much memory is to be allocated to processes. It decides which process will get memory at what time. It tracks whenever some memory gets freed or unallocated and correspondingly it updates the status. SWAPPING Problem: Mono programming is not really of any benefit to us now days. We need to be able
Introduction A basic operating system mainly contains 4 management functions includes process management, memory management, file management and I/O and disk management. Process management and file management will be mainly discussed in this case study. Process management This management function monitors and maintains processes running in the operating system. Task manager Processes In Windows 10, a user would need to access the task manager to handle and monitor running processes. This is
File servers are an important part of any business. The file server is the central location of files for a business small or big. The file server can be a cloud accessible server which grants accesses anywhere. The file server can also be a dedicated server which is only used on the business network. I am going to touch on the specifications of a file server. This means I am going to go over CPU, memory, bus, DMA, storage, interrupts, input/output peripherals, and monitors of a files server. The
stealing their content. File Management File management is used to keep, send and receive files efficiently so the files can be accessed easily. Using naming conventions and good file structuring are some ways for people to organize files and make it easier for themselves to access their work. Without good file management, the user will use up a lot of their time and effort trying to find the right files. A good example of good file management is putting all the python files in one folder and not have
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
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.
