UNIX AND LINUX Two Powerful Systems That Are Often Misunderstood Unix and Linux            There have been many-recorded eras throughout man’s history. There was the Ice Age (BURR), the Stone Age, the Bronze Age, and the Industrial Age (revolution) just to name a few. Each of these eras marks pivotal advances in humankind. Here are some examples of our advancements, during the Ice Age, one of nature’s

UNIX and Windows About Unix The Unix operating system is a powerful programming environment designed by and for computer programmers. Unix is available on a wide variety of computer systems, including personal computers, workstations, mainframes and supercomputers. It was developed for, and is particularly well suited to, multi-user systems, but is now also run on 'stand-alone' machines. Beginners and casual users often find the jargon-filled help system frustrating and the lack of

Comparing Microsoft DOS with UNIX As is suggestive of its name, an operating system (OS) is a collection of programs that operate the personal computer (PC). Its primary purpose is to support programs that actually do the work one is interested in, and to allow competing programs to share the resources of the computer. However, the OS also controls the inner workings of the computer, acting as a traffic manager which controls the flow of data through the system and initiates the starting and

UNIX, Linux, and Windows Server Critique UNIX, Linux, and Windows Server Critique Administration Windows Server Advantages There are many administration advantages for Windows Servers. One aspect is domain operations which are an important resource available on the network through Window Server. Making Window Server a domain controller adds security and the ability to add local and group policies to the network (Garza, 2010). If Window Server is not promoted to the status

Windows NT vs Unix As An Operating System In the late 1960s a combined project between researchers at MIT, Bell Labs and General Electric led to the design of a third generation of computer operating system known as MULTICS (MULTiplexed Information and Computing Service). It was envisaged as a computer utility, a machine that would support hundreds of simultaneous timesharing users. They envisaged one huge machine providing computing power for everyone in Boston. The idea that machines as powerful

1. You have just finished a 25-page paper that you have written using Emacs.The file containing the paper is called /assignments/data_sources. After your instructor has briefly looked at the paper, she recommends that you change all instances of the reference “data is” to “data are” before you submit it.Which of the following commands can you use to locate these references in the file for a quick assessment of how much you have to change? a. find - i 'data is' /assignments/data_sources b. test /assignments/data_sources

UNIX, Linux, and Windows Server Critique POS/420 Name Professor Date University of Phoenix Abstract The following sections in this paper focus on analyzing operating systems for Riordan Manufacturing Inc. that specializes in plastic molding and design. Team B concentrated on five main areas of UNIX, Linux, and Windows Server. The five areas include Security, Administration, Networking, Performance, and Programmability. The team explains the existing systems, followed by comparing advantages

Task 1 Processors (CPU) The processor (CPU) is essentially the brain of a computer system. The role of the CPU is mainly to process everything from basic instructions to complex function. The well known measure of the CPU is clock speed and it is measured in MHz or GHz. The different manufacturers of the CPU are Texas Instruments, Intel Corp, Centaur Technology etc.. Motherboard A motherboard (mobo) is basically the main circuit board of a computer system. All the different components

become accustomed to so many choices. One of the major choices in the modern era is the “Operating System (OS)”. Operating systems are the central software component to any computer. The main brands of operating system are; Windows Mac OS, Sun Solaris, UNIX, DOS and Linux. Each brand has its own take on what makes up an operating system. Windows is the most commonly used operating system around the world. The most common advantage about Windows is its simplicity. It is now very easy for an inexperienced

Open and Closed Source Systems June 24, 2013 Open and Closed Source System What Open Source Means Open-Source means it is free. No one owns it, so there is no source code, no key code, and no licensing to purchase. When Linus Torvalds created Linux, he determined that the more people or, the more minds delving into the software can make the system more creative, more improved, and the possibilities are endless. Thus, he gave Linux to the world as a free open-source operating system ("Damicon;

In the beginning of the age of the modern computer, programmers worked around the clock, creating code for their employers for use in proprietary computer systems. These elite programmers enjoyed challenging one another and frequently enjoyed stretching modern systems to their limits. These programmers became know as "hackers" for their talents at dissecting and working around difficult problems, often searching for the most elegant or most efficient solution possible. Unlike the vision

William Wang Christian 5th 7 April 2015 Capstone project Have you wonder where the power of technology and computers and all of the applications came from? Well there are a lot of computer applications like local security applications, protocols, well I am going to explain some security applications to you. There are many kinds of different security applications. I am going to explain two of different applications Linux and security policy settings. Now what are security policies? Security policy

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

examples would include Microsoft Windows and Apple OS X operating systems. Like open source systems, closed source systems offer software for a variety of uses that include personal, server and mobile. Open Source Closed Source Linux Red Hat Unix Windows 97, XP, 7, Vista Versions of Window Server Mac OS X Closed source systems are usually found in personal computers because the level of expertise needed to use them is minimal. There are many factors to consider when determining which
