...Shawn Saint-Germain NT1110- Computer Structure and Logic June 29, 2015 Module 2 Short Answer I/O devices are a vital part of any computer system. These devices enable the user to put data into the system (input) and receive a visual representation of what they put in (output). Some of the most vital I/O devices to make a system operable are the most common seen. One such device being the monitor. The monitor is the single most important output device to have on a system. The monitor allows for a visual display of all inputted data on the computer. Paired with the monitor, the keyboard and mouse are 2 input devices which allow the user to directly input data and various other information into the system. However, there are some input devices which are not necessary for normal use of the system. One such example being a webcam. Webcams allow for visual input into the system but is not vital for system functionality or performance. Due to the fact that a visual input device is not a normal form of input for a system. A modem is considered an I/O device for a variety of reasons. A modem allows for data input to the system directly from the internet and other systems, as well as allowing the system to output data to other systems. Another device that follows the dual functionality aspect is a printer. The printer is viewed mainly as an output device, allowing for data to be visually outputted to paper. The printer can also be considered an input device, depending on what type...

...Computer Structure and Logic Lab 1 12/17/2015 The computer I am working on right now has Windows 7 Installed on it. Windows 7 is not perfect. Some features are underdeveloped. For example when typing the cursor will move through the document. And some annoyances remain intact. But overall, the final version appears to be a worthy replacement to Windows XP. In window 7 you can take the Screen and split it into two. This is a great feature when you are writing a paper and doing research at the same time. To do this just click on the middle of the tab bar and drag left or right, then take your other screen and go the opposite way. In windows 7 you can now pin Icons to the task bar. For example you can pin chrome to your task bar, to do so open chrome, it will appear in the task bar when it does right click on it. Click on pin to task bar, now you have easy access to chrome. Windows 7 started the “Peak”. You can take your mouse and hover your mouse over an icon on the task bar that is active, when you do this a small screen pops up and you can see what is in that tab. Desktop Gadgets can be added to windows 7. You can add the Weather or even a picture slideshow to the desktop, just right click on your desktop and click on gadgets. Double click on the gadget you want and it will appear on your desktop. The desktop I am using has an Intel Core Processor the CPU is running at 3.30 GHz. It has 8 GB of RAM wish it had at least 16.

...Gerald Sutton Procrastination 1. Procrastination the practice of carrying out less urgent tasks in preference to more urgent ones, or doing more pleasurable things in place of less pleasurable ones, and thus putting off impending tasks to a later time, sometimes to the "last minute" before a deadline. Procrastination I found yourself putting off important tasks over and over again, and Im sure many people procrastinate to some degree – but some are so chronically affected by procrastination that it stops them fulfilling their potential and disrupts their careers. The key to controlling this destructive habit is to recognize when you start procrastinating, understand why it happens (even to the best of us), and take active steps to manage your time and outcomes better. Research found on the Internet. Now that I recognize procrastination as an issue Im seeking out ideas and strategy to help me overcome it by identifying and addressing the issues. · Disorganized : Organized people manage to fend off the temptation, because they will have things like prioritized to-do lists , organized people have planned how long a task will take to do, and will have worked back from that point to identify when they need to get started in order to avoid it being late. · Feeling overwhelmed by the task : Sometimes I may doubt that have the skills or resources I need, so I seek comfort in doing tasks I know I’m capable of completing.

...Market Structures in Computer Operating Systems When purchasing a new computer the discussion on which operating system to choose does not usually come up, as there had been a monopoly in this industry since 1985 (Bellis, 2013). Microsoft with its Windows platform is a giant in the computer operating systems industry. The Microsoft Windows market structure began in an oligopolistic market, became a monopoly, and developed back into oligopolistic. History – Early Years In the early years of Microsoft Windows, the competition for computer operating systems was limited to MS-DOS, VisiOn, and GEM (Graphics Environment Manager). All of these systems struggled in a small demand market because no programs were being written for them. There was no need for consumers to purchase the products. In 1990, Windows 3.0 was released and with its release came extensive third-party support by programmers. This created a huge demand for the system and the software programmed for it. This demand caused the competition to disappear from the market and propel Windows into a monopoly market (Bellis, 2013). Market Types An oligopolistic market is explained as a market where only a few firms compete, as opposed to a monopoly where one firm makes up the entire market (Colander, 2010). Microsoft Windows from 1990 to 2007 was a monopoly to the industry because consumers had no other choice or substitute for a computer operating system. This means the marginal revenue (MR) for Microsoft during...

...that take hold of structures that are built today and three – quarters of a century ago. These structures are designed and tested for weaknesses using computer simulation and this seems to be a problem that has caused loss of life as well as large financial loss. In order to keep these disasters from occurring the investment in a computer monitoring system, which would monitor the structural integrity of various buildings and bridges, would be beneficial from a safety and financial stand point. The implementation of this system should be begun immediately to prevent any further happenings. Further research into perfecting this system needs to be a top priority due to the fragile nature of the problem. INTRODUCTION By investing in a computer monitoring system that would monitor the structural integrity of structures, like bridges and buildings, the benefit would be much more valuable in the long run by saving lives and money. Instead of waiting for a disaster and then sending experts out to the scene to find out what happened there needs to be a monitoring system to give warning before the disaster even comes to pass. This technology would be a lot like using seismographs. The system would have to be wireless and would connect to a hub within a certain parameters. These hubs would be sporadically built in areas around the world. The individual hubs would monitor a certain number of structures for any sign of structural failure. The structures would be fitted with...

...BSA 310 May 15, 2011 Rich Harrell Critical Information Systems An Information System is an organizations framework for efficiency, productivity, and functionality. It “is a collection of hardware, software, data, people and procedures that are designed to generate and disseminate information and data that supports the activities of an organization” (International Graduate, 2011). Kudler Fine Foods is an organization specializing in providing domestic and imported sustenance to consumers. This paper clarifies an information system critical to their business process and examines how this system has an effect on the organization’s intricate structure. Information Systems Information systems used by organizations often follow a “traditional hierarchical structure” (Turban & Volonino, 2010. p.42). The structure commonly consists of seven functional types (1) Personal and Productivity Systems, (2) Transaction Processing Systems, (3) Functional and Management Information Systems, (4) Enterprise Systems, (5) Inter-organizational Systems, (6) Global Systems, and (7) Special Systems. Each category plays an essential role in the overall function of an organization when utilized. The development of an application program is used to execute or support a specific organization task or business process through the use of that information system. Although system types and applications can be independent of each other, most systems and programs are often reliant on each...
