Sobell Fedora and Red Hat Linux Chapter 1 Answers Essay

The Operating system is one most important parts of anything that runs on technology. It manages the computers memory and processes the information for the software and hardware. There is different operation system for pc, tablets, smart cars, and smartphones.

A computers operating system (OS) is the core of the computer and is more than just software. The OS controls the computer’s memory and processes as well as its hardware and software. It is the brain of the computer. Software applications on the other hand perform a certain task. Ex. Google Chrome provides internet and Adobe allows PDF files to be read (among other things). The OS is what makes all of these applications work successfully and accomplish whatever the application is designed to accomplish.

Linux is the most important free software it has developed into a an operating for business , education , and personal productivity. Linux is so different because of its free implementation of Unix

Usually, attackers will take advantage of known vulnerabilities, such as Shellshock, to gain access to areas on computers, websites, databases, etc. that are not permitted. Typically what first needs to happen before an attacker can execute any code is they need to establish a way into the target and find a way to deliver the payload. Malware is the most common delivery tool to gain access to a vulnerable system. Once the target has been infected, the next goal of the attacker is typically to gain “shell” access. In the realm of computer systems, a “shell” is a terminal where commands can be directly entered and executed by the host operating system. With the large amounts of malware spreading throughout the web today, this unfortunately makes unprotected devices an easy target for disaster. What’s even more disturbing is the fact that malware doesn’t need to be implanted on a Shellshock affected system since Bash alone causes the issue. Thus, an attacker has free reign on a machine with little effort and can perform various types of malicious

The first OS we are going to look at is Linux, it can be a hard system to use and understand, if you have not used it before, you must have a good knowledge of computers in order to deal with Linux. Commands have to be typed in on the command line, and most people do not know or understand command line text. Linux does not have a great number of vendor selling their computer or software, so there is not a good support system for it.

When I encountered command line during last week’s class, I found it a little confusing and “aloof”. I was totally unfamiliar with its purpose and syntax, and the interface is merely characters of same font and size. I thought it is something only for computer science students and does not have anything to do with web design and interaction.

1.) PowerShell is an object-oriented programming language and interactive command line shell for Microsoft Windows.

| It is hard to understand the system of Linux because most people are not familiar

In the workplace today there are many different options for operating systems be they providers of server related services or end-user desktops there is a different Linux distribution for many different applications. There are also a number of advantages and disadvantages to adding onto or switching network operating systems within a company. In the following pages I

This paper analyzes and compares the differences between the Windows and Linux’s operating system in an enterprise. It emphasizes the features in these two operating system such as history, cost, security, user-friendliness, performance, and future trends. It shows how impactful these features can be when an enterprise chooses an operating system. The research in this paper highlights the pros and cons of an enterprise using one operating system or the other. It directs the readers to have a better understanding on which operating system is better for specific instances. Readers will have an enhance perception on Windows and Linux and the platforms they serve. In our paper we try to fully analyze Windows and Linux’s operating system, so an enterprise can choose the best operating system for themselves.

Linux is a trademark owned by Linus Torvalds [1]. It is an operating system which is powerful, free and inexpensive to own based on UNIX [1]. It is a POSIX-compliant with versions available to install in cell phones, supercomputers and most computing systems [1]. Linux is an open source program as its source code is available to the general public for use and the right to modify from its original design without any charges [1]. New code will be added to the next version made available with Linux if it is accepted as a universal improvement [1]. The code will continue to exist and developed by the user even if the company fails [1]. Moreover, updates for Linux are available every six months [1]. Nowadays, Linux is in constant development by

Windows and Linux provide a GUI (Graphical User Interface) and a command line interface. The Windows GUI has changed dramatically from Windows 3.1 to Windows 95, slightly to Windows 2000, big change to Windows XP and is scheduled to change again with the new version of Windows recently named Vista. Themes is a feature in Windows which lets you customize to an extent the look of your GUI. Linux typically provides two GUIs, KDE and Gnome. Of the major distributions, Lindows has made their user interface resemble Windows a lot more than the others. Text mode interface is also known as a command interpreter. Windows users know this as DOS prompt. It is called a shell in Linux. Windows has a single command interpreter but the different types of Windows have different interpreters. Linux, just as all versions of UNIX, supports multiple command interpreters, but Linux usually uses one called BASH (Bourne Again Shell). A few other shells are the C shell, ash shell, and the bourne shell.

Three operating systems discuss in this paper each have their advantages and disadvantages from one another. The biggest advantage for Microsoft is the widespread use and compatibility with most every type of program out there. If you 're a Linux fan then you appreciate not only the price which is usually free but also that it is

The Linux was originally founded by Linus Torvalds. In 1991, he was a second year computer science student in Finland. He sought after an operating system that was similar to the UNIX system, but both UNIX and the hardware it ran on were excessively expensive. A UNIX version called Minix was available for free, but it did not reasonably meet his needs as it was simply an operating system for students, designed primarily as a teaching tool rather than an industry strength operating system. As a result, Torvalds studied Minix and proceeded to set out to write a new version. After six months of working to produce the new operating system, Torvalds made very little progress toward the utility of the system.

In Windows, you can run lots of different program programs. There are customized programs and off-the-shelf (common) programs. These allow you to do everything from running your bowling league to typing up a correspondence.
