...NT 1210 Lab 3.1.1, 3.2.1, 3.3.1 The Purpose of Reference Models Exercise 3.1.1 What would happen if wireless devices were not governed by the Wi-Fi Alliance and each vendor had its own standards and protocols? What impact would this have on your personal life or business communications? The process of marketing the wireless devices would be much slower than if the Wi-Fi Alliance wasn’t governing them. This would impact my personal life or business communications in a big way. The reason is Wi-Fi Alliance certifies the products through pre-standard rules thus insuring the speed of product market and quality. The OSI Reference Model Exercise 3.2.1 Define each layer of the OSI Model and state what each layer provides. Physical – transmission and reception of the unstructured raw bit stream over a physical medium. Carries signals for higher layers and describes the electrical /optical , mechanical and functional interfaces. Data link – Error free transfer of data frames from node to node over the physical layer , allowing the higher layers to assume virtually error –free transmission over the link. Network - is the third layer, which controls the subnet operation by deciding which physical path data should take based on network conditions and priority of service with other factors. Transport - is the fourth layer, which ensures the error-free delivery of messages in sequence and with no losses or duplications. Higher layer protocols are relieved from concerns with data...

Hello most esteemed US computer guru, Thank you for setting up our branch office in the US. However, our data center has a problem. It seems that everyone there is in love with Office Depot and has a printer on their desk. We employ 150 people. This is too many printers. The ink is so expensive. I hear many people come in of Saturdays and print baseball schedules, shopping list, and photos of their family. What can you suggest to help me? Thank you! From: AA To Rebop Pakulah Hello Rebop; glad to hear your company has increased in employees and volume. Rebop I cannot believe almost every user in cubicle has their own printer. This must stagnate your network, not to mention office expenses for toner and repair calls. Here is what I am suggesting for your 150 employees; you should have 3 multipurpose printers HP4555mfp printers. Then perhaps keep about 10 small HP printers that may belong to your admin staff, such as HR, Recievers, accounts payable team, and those employees that use a printer for 75% percent of their duties. All of these printers would be added to the network server, the subnet, gateway, and IP would be assigned to each printer. After that rules can be added to these printers, such as standard settings, if a user needed to use a portrait printer setting...

...GS 1145 Strategies Unit 11 Assignment 1 Reflection Kelly S Draney This class has been an eye opener for me in respect that I was a real procrastinator. It has helped to open my eyes to the fact that I need to get my homework done and in on time. With the assignment on scheduling I found that I wasted a lot of time during the day, when I could be getting things done. Breaking down my schedule into blocks showed me that I had a lot of wasted time watching TV when I could be more productive. Having to juggle time for work and school was something I was not accustomed to. I have a greater respect for my students now seeing what they have to go through. The other thing this class helped me with, was learning how to use the Microsoft Office Suites programs better. I had no idea how to use Power Point before this class. Gratefully we were put into small groups to work on these projects. The good thing about these projects was it gave me a chance to learn about Power Point. I was surprised how easy it really is to use. It also helped to learn the different rules about completing a Power Point Presentation. I enjoyed being in your class. I heard a lot of good comments from students who felt you were tough, but fair. You created a fun learning environment in class. I look forward to having you again for an instructor later on in my studies....

...Windows 8 is a Microsoft operating system that is designed for home users as well as for business purpose. Its development started even before its predecessor’s release Windows 7 in 2009.Windows 8 is a system that is particularly orientated to touchscreen hardware. There are some important changes and additives that make it look and differently than the users are used to. For example, the Start menu is completely substituted by a Start screen that can be taken away from the desktop easily by touch screen pen and also by just a normal mouse or keyboard key combination. It contains all the important applications also the ones that are active at the moment. All the icons in the old version of the operating system are changed into tiles that can be juggled with. It can stay constantly on the screen or can be hidden.And now the most important that users expect to hear – when will it be available for the public and for what price? The official release date is the 26th of October, 2012. It was preceded by three pre-release editions while still being developed and tested for the period of the 13th of September 2011 until 31st of May 2012. There will be four editions issued on the market – two general editions just for conventional use, one Pro release of Windows most ardent devotees and Enterprise edition which is for business purposes. ² Windows 8 is the current release of the Windows operating system, produced by Microsoft for use on personal computers, including home and business...

...WEEK 8, ASSIGNMENT 2Ireti Kayode Strayer University | | CIS 175 Dr. William McConnell12/03/2013 | | | | | Ocper, Inc. Server Proposal Given Ocper, Inc.’s expanding network scenario there is a clear need to maximize the available resources between employees then it is appropriate to add additional servers to facilitate the sharing of files as well as the configuration of remote access services to allow for remote and secure working. In order to complement the existing network scenario this proposal is based around the configuration and deployment of Microsoft Windows Server 2012 as the network operating system. This is a stable and secure server environment which will allow the designated services to be configured and will equally allow for scalability while at the same time decreasing the overall maintenance and administration to support the network and associated servers. Given the size of the current organization and the IT systems at present, Windows Server 2012 Standard edition would be the most appropriate version for deployment as this will also keep the up-front costs down to a minimum – there is no requirement for the Enterprise Edition whose features will not be required in this implementation. One of the critical roles for the new server implementations will be that of a File Server capability – this can be easily configured within the Ocper, Inc. network through a Static IP address being assigned to this machine and then the...

...Updating From Microsoft Windows XP to Microsoft Windows 7 A lot of problems can arise when trying to update an older machine such as this from Microsoft Windows XP to Microsoft Windows 7. Microsoft has not made it easy for XP users to move to Win7. You won't be able to run the upgrade disk and have the newer operating system install on top of XP, leaving your data and programs in place. Instead, you have two options: 1. You can do a Clean install, in which you wipe the hard drive clean and install a virgin copy of Windows 7, then reinstall your software and copy your data back to the drive. 2. You can do a Custom install, in which your older setup is squirreled away in a folder called WINDOWS.OLD. This will include your program files, though you won't be able to run your software from there. It will also include data files, but you shouldn't rely on this as your sole backup strategy prior to upgrading. First and foremost When performing and update such as this: make sure that all hardware on the machine that is being updated is compatible and will meet Windows 7's minimum system requirements. A good way to do this is simply to go to the Microsoft website and download the windows 7 advisor at: http://windows.microsoft.com/en-us/windows/downloads/upgrade-advisor. This tool can be very helpful in determining if a system is capable of running windows 7. Some of the Windows 7 system requirements are: * 1 GHz processor (32- or 64-bit) * 1 GB of RAM (32-bit); 2 GB of...

...The current architecture of the Riordan Manufacturing Company Inc. Wide Area Network and network security in place requires updated documentation. The purpose of this paper is to gather the existing information into a single format and evaluate the WAN and security documentation for an executive overview. Riordan Manufacturing, Inc. is an industry leader in the field of plastic injection molding. With state-of-the art design capabilities, they create innovative plastic designs that have earned international acclaim. Attention to detail, extreme precision and enthusiastic quality control are the hallmarks of Riordan Manufacturing. With facilities in San Jose, California, Albany, Georgia, Pontiac, Michigan and Hangzhou, China, the company is heavily dependent upon their communication networks. The documentation produced by this analysis will give the management at Riordan Manufacturing an understanding of their networks today, a plan for future upgrades and a baseline to evaluate security. The goal of this exercise is three fold. Our first will be to provide an inventory of the existing network components for Riordan Manufacturing designated by location, review the network security for each site, and our last goal is to document the current security plan for use in future planning. Because of the limited scope of the project, several assumptions must be made. The first assumption is that Riordan Manufacturing has accurate records of the current infrastructure and no changes will...
