Technology Infrastructure Essay Example for Free

Technology Infrastructure Essay Information Technology Infrastructure is the integrated framework upon which networks operate. The infrastructure is the physical hardware used to interconnect computers and users or in some cases it is viewed as everything that supports the flow and processing of information, the transmission media, which includes telephone and cable television lines and also the routers, repeaters and other devices that control transmission paths. The software used to send, receive and manage the signals that are transmitted is also part of the infrastructure and should be managed and designed accordingly in other to have an effective network. In this final paper I will assess, compile, update and synthesize all the information that I have collected throughout the 10 weeks. A proposal will then be written to address some problems and deficiencies which were uncovered in the network and what my proposed solution is. Part 1: Network Assessment  The network that I have been characterizing is a small local area network for an Accounting firm in downtown Manhattan. The network will be made up of 14 workstations where 8 will be used for invoice billing, 1 for the manager, 2 for the IT department, 1 for reception the 2 others will be left unused just in case employees from other offices are there on business and need to access work related files. The LAN is being designed with the hope of expansion to another floor in the coming months so provision is made with this in mind. Considering the size of the organization I chose to design a LAN because of it is cost effective, because of the connectivity and communication which allows users to communicate be email with each other, Data Sharing lets the networked computers share data with each other and because Data Security and Management allows the administrator to manage the data better. I also kept in mind that instead of installing software and updates to each individual computer the software can be uploaded to the entire network and dispatched to all computers on said network eliminating time and expenses. Designing this network called for effective Information Technology planning which is a key ingredient in achieving strategic business success when implanting a network or any type of information technology infrastructure. Because the network is comprised of 10 workstations and the manger as well as the CEO will be using laptops I have chosen to use fiber optic instead of regular cable especially due to the amount of noise present in cable communication media with a DSL / Digital Subscriber Line internet connection while incorporating wireless service for laptops and visiting employees as well as those who work from home. Though Fiber-optic seem to be a bit pricy my decision to go with Laser Fiber Optic was based the company needing the computers to be up and running all day and making sure that the lines are secured. Secondly because the company is thinking of expanding to another floor we need the transmission range to maximize, so 100 kilometers as far as transmission range is important. The only other alternative media that I would consider is the thick coaxial cable but we would need to incorporate the use of repeaters after a 100meters when the company is ready to expand. The main issue to consider is how secure this line is which is the reason why Fiber-optic would be the most trusted and efficient. My third reasoning behind choosing fiber again is the potential noise issues which could slow down the network and cause disturbances. Two specific points where I think noise will be present are when employees are working from home trying to connect through the VPN connection in windows XP there can be attenuation issues which is loss of signal strength. The VPN connections allow window XP clients to connect to a VPN remote access server by using PPTP and LT2P network protocols. Secondly with the wireless network infrastructure implemented if too many users are trying to use the same channel (not enough bandwidth to go around) and the adapter settings are not done properly then there are bound to be interruptions with the data transmission, any form of signal issue is a potential for noise. My recommendation to eliminate this issue would be keeping the routers in an area central to the rest of the devices that will be connecting and changing the wireless channel on the router associated with the wireless connection. The key devices needed to put the network together are 2 servers, (one will be used for backup although we are using cloud computing) CAT6 cable, 2 wireless routers / wireless switches, a network adapter and a repeater. All these devices together links up all the local and remote network segments with each other to make data communication flow better. Because of the size of the network there are a number of peripheral, devices applications and data that will be shared by users on the network. Some of the peripheral devices include the router and modem which will be used to connect all the computers, the printers and copiers, scanners for scanning documents and file and folder sharing. Some of the application software shared will be emails, internet and the web browser. Everyone on the network will also share the same operating system which will be windows 7. The document sharing will be shared among the users on the same network because they all will be connected to the main server. When updates need to be made it won’t be sent to individual computers instead it will be sent through the network and server so all computers are updated automatically. Although a license has to be purchased for every user who is using the software on their individual computers everyone will be able to share and use the same program or software on the network as long as they are connected. Because of the partial wireless nature of the network, there are a number of protocols with needed to be implemented. The two protocols that are implemented are PPPoE and PPP. PPPoE stands for Point to Point Protocol over Ethernet and PPP stands for Point to Point Protocol which is a member of the TCP/IP suite of network protocols. PPP is usually used over serial communications like dial-up modem connections. The advancement of technology has brought hackers and cyber-attack at an all-time high, so securing the network deemed a bit challenging especially due to the wireless part which possess security and technical challenges. Some of the security issues include viruses, worms, denial or service, hackers and the list goes on. To secure the data on the LAN I will be implementing Data Encryption Standard which is a commonly used encryption method used to send and receive secure transactions. To avoid and intercept viruses and worms I implemented an antivirus called the Symantec Endpoint Protection. Symantec Endpoint Protection offers great performance and support for virtual environments; antivirus scans are reduced because of layering technologies like insight which lowers the risk of cyber criminals. The third form of security that I have implemented is the use of a firewall. A firewall is a system or combination of systems that supports an access control between two networks so in this case it would be between my LAN and the WAN which is the World Wide Web. A firewall limits users on the internet from accessing certain portions of a corporate network and can limit internal users from accessing various parts of the internet. This is where access control would play a part. Firewalls come in two basic types, packet filters and proxy servers. Packet filters examines all incoming and outgoing transmissions and filter out those transmissions that are deemed illegal. Proxy’s on the other hand are computers running at the entrance to a computer network and acting as a gatekeeper. Finally because of the wireless part of my network I will need to make sure that there is wireless security implemented by making sure that a password is used to long in. The use of WAP (Wi-Fi Protected Access) will be used as the encryption key to keep the wireless segment protected and secured. In relation to physical security I recommend always locking up the server rooms, turning them off will save on power but won’t avoid unauthorized persons from tampering, ensuring that there are good locks on the server door is crucial. Secondly disconnecting and removing computers that are not being used and locking them up is a way to prevent hackers from accessing unsecured computers that are connected to the network. Employees who are out to lunch should also lock their computer to avoid the fellow employee from accessing files that they are not authorized to see. The third physical security option is disabling the drives; If you want to prevent your employees from copying information to a removable media disabling or removing floppy drives, USB ports and any means of connecting to external drives is important. Disk locks can be inserted into floppy drives on the computers that are restricted. The forth physical security I would install is a backup server, not at the current location but somewhere away from the office. In case there is a fire in any of the office or someone messes with any of the computers, the files will be stored at a secure location outside of any of the offices that the company in question has. Network security starts at the physical level, having firewalls won’t deter an intruder who is able to gain physical access to your network and computers’ so locking up well is the key. Although every aspect of the network was addressed there were some issues that came up towards the end of the project right when the company was about to lunch the new system. The 2 deficiencies that came up were related to the hardware which was associated with the physical structure of the network as well as performance issues. Part B: Proposal Document Project Justification: The LAN has the potential to be a great network because it has the potential of expanding into a WAN, so to address the problems which were just discovered I have put together a proposal which is guaranteed to eliminate the hardware and performance issues associated with the connection on the network. It is important that the hardware issues which includes the printers, telephone lines and VPN connectors are dealt with before the new network is completely lunched because not only is invoicing done for clients in the New York, but the office in Tokyo needs to access the same files and need to be able to send documents to the printer/ fax machines with no encumbrance. The current infrastructure’s VPN connection was not configured correctly so during testing it was brought to my knowledge that anyone who would be working from home would have issues getting a connection. Secondly with the installation of the VoIP telephones we realized that the connection was not clear and any long distance calls which went over 5 minutes would be disconnected. The performance issues which had been a problem from conception stemmed from me not taking into consideration the applications that were going to run on the network and the use of a hub instead of a switch.

Essay on Brutalities of African Society in Chinua Achebes Things Fall

Brutalities of African Society Exposed in Things Fall Apart      Ã‚   David Carroll writes, of the novel Things Fall Apart, "This incident is not only a comment on Okonkwo's heartlessness. It criticizes implicitly the laws he is too literally implementing..." (Carroll) The incident that David Carroll refers to is the death of Ikemefuna. Ikemefuna was a young boy who was handed over to the village of Umuofia as compensation for the murder of one of that village's citizens. He is handed over to Okonkwo, a great man in the village, to whom he gives every affection. The brief life with Okonkwo and death of this innocent young man, and the life of Okonkwo himself, is a microcosm of life in Umuofia. Inconsistencies, brutalities, and conflict abound in even the highest of Umuofian life. And as Ikemefuna is led off to be murdered by the man he calls father, "the whole tribe and its values is being judged and found wanting" (Carroll).    When Ikemefuna first arrives in Umuofia, he is housed with Okonkwo because Okonkwo is a great man in the village. He had reached his prime and was a man of wealth. Ikemefuna quickly befriended Okonkwo's eldest son and began calling Okonkwo "father." Soon, however, this seeming peace and civility in the village and the life of the villagers disappears. Okonkwo receives a message from the village elders that the boy, the town's innocence, must be killed off. The boy is lead off to the slaughter completely unaware of his fate, and with his "father" in the company of the killers. When a machete is drawn and the black pot atop Ikemefuna's head is cut down, the boy runs to the man he loved as father. It is he who, lacking the courage to confront the others with his love for the boy, draws his machete and... ...e on the things that held us together and we have fallen apart" (Achebe, 176). The village of Umuofia held to backward laws and values that "destroy innocent children" (Achebe, 146). The tribe's innocence had to die in order for those who survived to mature. Although Umuofia's peak of innocence may have been when Ikemefuna was handed over to the village, but its maturity would come through the death of Ikemefuna, the tribe's innocence, at the hands of those the tribe called "father." Things Fall Apart clearly illustrates the faults of the African system and way of life through "the series of catastrophes which end with his [Okonkwo's and Umuofia's] death" (Carroll).    Works Cited Achebe, Chinua.

Using Home Design Software - A Review

Home Designer ® by Chief Architect is a line of software programs for non-professionals. Intended to help the Do-It-Yourselfer (DIYer) create workable home and garden plans, these applications cost less than professional-grade software. Not simplified or simple-minded,  Chief Architect products can teach you more about construction and design than a semester course at the local community college. And they are fun to use. Advertisements promise that this software will save you from napkin sketching, thanks to an integrated mobile Room Plannerâ„ ¢ app which lets you measure and plan rooms on the go and then import the file into Home Designer. You might love napkin sketching, but youll still want to test out the next step in home design. For the inexperienced, try out the middle-of-the line product, Home Designer Suite. You may hit some bumps along the way, but youre sure to find some happy surprises. Heres the scoop on the 2015 version. Using Home Designer Suite Every year is a new version, but most applications work the same way. Download files from homedesignersoftware.com or purchase the DVD. Installation is the straightforward 10-15 minute process. Then jump right in. Create New Plan makes you choose a house style before anything else. This gets you thinking about what look you want for your new construction or what style your built house might be. Of course, the problem with style is that very few house styles are pure Colonial or Country Cottage or Arts Crafts. Select one of the style choices, however, and you get a simple illustration along with written content that defines what they mean by the style. For example, Urban Chic/Contemporary is described as clean and spare. When you first begin, the software prompts you to make decisions — for example, choose a core catalog for your library, framing defaults, exterior siding. Construction pros understand the need to know wall height and thickness before building. However, if you are impatient, you might feel frustrated by the need to choose style details before getting started. The house style you have chosen loads an array of default style choices. Not to worry, however — these defaults can be changed at any time. Still, the creative side of you  may begin wishing for the napkin part of the process — a distraction-free work area to sketch out your inspirations. Building, Not Drawing The default work area in Home Designer looks like a piece of graph paper, although this Reference Grid can be turned off. The unsaved file is called Untitled 1: Floor Plan, so you may want to get into the habit of saving your electronic work often, just as you would in any software program. The cursor is at the crosshairs, beginning at the 0,0 point of an x-y axis. Its all movable, so the new user may reasonably decide to draw a floor plan with a drag-and-drop motion. But Home Designer in 2015 doesnt work like that. The user of Home Designer software does not really draw or sketch a design, but builds and constructs a home. If you begin with the Build drop-down menu, you will see Wall at the top of the list. Each wall section is considered an Object, so once each object is placed, you can select and move it around. The program functions like a builder — it progresses one wall at a time, one room at a time. An architect often thinks more abstractly and conceptually at first — a sketch on a napkin. In contrast, Home Designer functions more like a builder. Using this software, you may feel more like Bob the Builder than architect Frank Gehry. Results: The Wow Factor The very impressive 3D renderings will amaze you. The floor plan that you build can be viewed in multiple ways — overhead like a dollhouse, different camera views, and even a virtual walkthrough along a path you define. This DIY software takes away the mystique of any architect, designer, or construction professional who tries to wow the public with a virtual reality presentation. Anyone can do it; its baked into the software. If You Dont Read the Directions First Remember this, if youre not in the habit of reading instructions before you begin (you know who you are):   (1) Use Build then (2) Select objects to move and modify. In addition to this Build and Select method, Home Designer Suite has two more ways to get your project going: Tools Space PlanningCreate Room Boxes to rearrange, then select Build House from the drop-down menu and poof — the walls and rooms are all there.Go to the Home Designer Samples Gallery and download a zip file of sample plans and renderings. One look at the floor plans and 3D views, and youll say, Yeah, I want to do THAT! A nifty aspect of these sample plans is that they are not static or read only — you can take designs that someone else drew and modify them to your own specifications. Of course, you cant professionally USE them in any official way, because that would be stealing, but you can get a jump start on the learning curve. Product Documentation Tells All Every new edition of Home Designer Suite has its own version of a Users Manual and a Reference Manual. A very, very helpful feature of the Chief Architect website is that the company doesnt throw away much  Ã¢â‚¬â€ from the Product Documentation page, you can choose your version of Home Designer from a drop-down menu, and a PDF file is available for your product and the version (year) of the product. If you read the Reference Manual first, a first-time user may better undersand the focus on objects instead of concepts in the software environment created by Chief Architect. The environment is built on object-based design  Ã¢â‚¬â€ object-based design technology means you place and edit objects, rather than work with the many individual lines or surfaces used to represent them. The environment is 3-D drafting, a three dimensional coordinate system...using the X, Y, and Z axes. The current position of your mouse pointer displays in the Status Bar at the bottom of the program window. Architectural objects take up space in all three dimensions and their height, width and depth can be specified....In addition, the location of objects can be precisely defined using coordinates... How Easy is Home Designer Suite to Use? When the video says, Its that easy, well, its not that easy. For the uninitiated DIYer, a half-days worth of fiddling and training is recommended to become even semi-productive. Even after a full day of fiddling, front porch columns may go through the roof or stairways may end up as high as a rooftop. Although there may be easier ways to draw a floorplan, Home Designer software really gives a professional look to even the simplest of floorplans. While designing the floorplan, its very easy to switch to a different view, such as a 3D overhead called a dollhouse. When viewing the outside of your design, you can easily place your new home in a stock photograph setting or its even more fun to choose your vegetation from a list and do your own landscaping. The online Support Center and drop-down Help menu are phenomenal. Help documents are constantly being updated, including: Frequently Asked Questions and Knowledge Base, a database of FAQs and solutions to specific questionsHome Designer Getting Started Resources, which may include access to too much informationClassroom Training, Webinars, Online and Mobile Training VideosCustomer Service Telephone SupportHome Talk forum and discussion group specifically for Home Designer software users The newbie might want to start with a quick tutorial and then reference the online Users Manual and the Reference Manual. 5 Reasons to Use Home Designer Software It makes you think about design, how elements/objects fit together, and how standard sizes and shapes of appliances can dictate interior design.It may save you money when you use an architect that charges by the hour. If you can conceptualize your ideas using the language of the professional designer or architect, communication will be faster and your expectations can be better thought through.The many standard features will keep you busy for weeks. The uninitiated will not outgrow this software anytime soon.Not only does the software integrate with the Room Planner app, but users can import photos of their own homes for landscaping and remodeling projects.Great support. Affordable price. Other Considerations Once you get the knack of using the software, its just too easy to make complicated designs. Walls and juts are easy to add, but theres no on-screen calculator to show you the immediate construction costs of what you are doing. Beware of sticker shock! Three-dimensional renderings include a snazzy ability to record a virtual walk-through. However, you will not be able create the simple yet elegant line drawings found in the work of professional architects. For that type of elevation drawing, youd need to move up to the Chief Architect product line created for professionals at chiefarchitect.com. Too many options can be paralyzing. Take your time and build your knowledge. Green initiatives and Green Building Software Tips are available online for the Chief Architect professional software. It would be nice to see these tips directed to the everyday consumer, too. Chief Architect, Inc. offers two lines of software products: Home Designer for the Do-It-Yourselfer consumer and Chief Architect for the professional. Both product lines are by Chief Architect, and both are described as Home Design Software. Which program to purchase could be confusing, so check out both the Home Design Software products and the Chief Architect product comparison. Chief Architect has been making professional architectural software since the 1980s. The Home Designer line builds on years of experience with a complex interface. The heftiness of the manuals and the need for so much support suggests the possible need for a more intuitive user experience. Fortunately, the documentation is excellent. After a day of tinkering and discovering what is possible, anyones imagination should soar.  Home Designer can be challenging to master, but well worth the effort. Cost The Home Designer family includes multiple products that range in price from $79 to $495. Students and academic institutions can license the products when adopted as a teaching tool. Trial downloads are available, and Chief Architect backs all products with a 30-day money-back guarantee. If your home projects focus on remodeling or interior design, Home Designer Interiors might be a better purchase at $79. Internet access is required for installation, license authentication, deactivation, video, and library catalog access. Internet access for license validation is required once every 30 days; for Home Designer Pro, license validation is required once every 14 days.
