...Peripherals 4 Networking 4 Security 5 A Comprehensive and Secure Solution Even small businesses can benefit from a solid network. Due to the unique nature of the site and the number of offices a Microsoft based small business network suits the location perfectly well. For this business I recommend purchasing 20 HP Desktops with standard peripherals, a wireless N based network infrastructure, and a Microsoft Windows 2010 small business server for user authentication, file sharing, and security. Desktops and Server The HP 6305 Small Form Factor desktop is an excellent option for this deployment. IT comes standard with a dual core AMD A4-5300 processor which has a 3.4 GHz core speed and a 1MB cache, built in Radeon HD 7480 Graphics, 8GB of DDR3-1600 RAM and a 1TB HDD. Windows 7 64-bit comes pre-installed; a 64-bit operating system is required to take full advantage of the 8 GB of RAM. Also installed is an Intel 7260NB 802.11a/b/g/n wireless network card to support a wireless network which will be discussed later. These machines will provide plenty of local storage and sufficient processing power to handle all standard business applications with sufficient RAM to handle most multitasking scenarios. For a centralized server an HP ProLiant ML310e Gen 8 will provide 2TB of storage for shared files while providing a 1 HDD failure tolerance, the server will also provide a centralized management of the network as well as proxy services through Microsoft Threat Management...

...Network Trends Prepared by: Rossell Powell Professor Yana Todorova ISSC321 I002 Win 12 American Public University 02-25-2012 Networking abilities in households is an important feature as an increasing number of students attend school online and still others work from home. With this increase, an increase in the number of computers in the household increases and all are dependent upon one Internet source. There are advantages and disadvantages to household network set-ups ( Dubendorf, V. A. (2003) The advantages in the ability to form a home network are numerous. The three main advantages to home networking are: sharing a single Internet connection among multiple computers, sharing files among computers, and using a printer or other device connected to another computer. Another advantage is that less wiring is needed when additional computers have wireless capabilities (Freeze, J. T. 2000). “The addition of wireless capabilities to these gateway devices gives the user the convenience of taking a computer anywhere in the house, and not have to worry about running wires through walls and crawl spaces and attics to connect computers in various parts of the house” .While the student is doing homework, the parent can continue to do work online and access their e-mails. Security issues are the biggest disadvantage to home networking. From , there are at least four types of security issues that exist. The first is bandwith parasites that use another person’s wireless connection...

Our first assignment related to the bookstore project was to identify the hardware and software as well as the databases and data communications. We were tasked with how the bookstores use the different databases, such as what information is stored, and what are possible issues. Our team identified several databases, as well as software and hardware used for the bookstore as part of the bookstore project research. Week Two Objectives were to describe how and when to use databases in business; determine data communications needs based on business function; and use Microsoft office to accomplish business objectives. There were several database options that our team had to choose from in order to suit our bookstore project; our team decided on what we thought would be the best and least expensive to suit both our project and budget. Our team also went with the best options that pertained to software and hardware for our book store project. There were many options amongst the providers, but we decided to go with options that would the best financial benefit, and offered longevity. Week Three’s objectives were as follows: determine how and when to use Internet technologies in business; determine collaboration tool needs based on business functions; write a discussion about whether the companies are meeting their business objectives; use Microsoft Office PowerPoint to accomplish business...

...factor in the cost of setting up a network infrastructure, network security, storage, redundancy, backup, and maintenance. Compare that to a commercial PKI solution, it is considered more profitable in the long run to pay for the service and not worry about all the factors above. It is mainly the control ability that drives companies toward an in-house PKI solution. In return, in-house PKI costs rise because it requires a separate security model including hardware storage solution in order to contain certificate repositories and public keys. The additional security model includes server, router, firewall, and IDS to keep hackers out. Additional software associated with a PKI infrastructure includes operating system for the server, Microsoft Certificate Server software or commercial based software, licensing, and secure backups. Due to the higher level of security requirements associated with PKI structures and private keys, the secure backups would be separated from the everyday backups found in a standard corporate backup system. Furthermore, a separate server is needed for certificate repository which will add even more costs and maintenance to an in-house design. On the other hand, using a commercial PKI would eliminate all those cost factors because most of those hardware and software infrastructure is located and maintained off-site which is included in the service price. In a single service package, a...

...implemented in hardware and software. There are thousands of communications protocols that are used everywhere in analog and digital communications. Computer networks cannot exist without them. With KFF, being that the Home Office or Headquarters is located in La Jolla, there is a T3 dedicated line that connects HQ with Del Mar and Encinitas locations. These lines are usually rented at a monthly or yearly rate to connect geographically separate offices for private voice and or data networking. It is also very costly averaging over $3000 USD per month, so most don’t lease these lines. They are also reserved circuits that operate over either copper or fiber optics cables. One of the protocols that should be implemented is the Transmission Control Protocol/Internet Protocol (TCP/IP). TCP/IP is the set of rules for communication on which most major networks, such as the Internet, are based. TCP/IP has become standard for transmitting data over the Internet and all operating systems such as Microsoft Windows, Mac OS and Linux. All...

...A Comparative Study of Cognitive Radio Platforms Moshe Timothy Masonta CSIR Meraka and TUT P.O. Box 395 Pretoria 0001, South Africa Mjumo Mzyece Tshwane University of Technology (TUT) Pretoria, South Africa Fisseha Mekuria Council for Scientific and Industrial Research (CSIR) Pretoria 0001, South Africa mmasonta@csir.co.za mzyecem@tut.ac.za fmekuria@csir.co.za ABSTRACT Cognitive radio (CR) technology has become one of the buzzwords within the wireless communications community over the past 12 years. Its ability to learn, decide and adapt to the external environment made CR attractive to regulators, researchers, academia, politicians and the industry. CR promises to bring a paradigm shift in spectrum management policies from command-and-control regime to dynamic and opportunistic spectrum access. Despite more than a decade of research in the CR area, there are too little CR systems ready for the market. This lack of ready CR systems may reflect an overemphasis in the CR literature on theory and simulations with less work done in experimental-basedresearch and publications. In order to fast-track the real-life deployments of CR systems, the research community is now focusing on the development of CR platforms. With different software defined radio (SDR) packages and hardware available, it is confusing to decide which one to build or use. The objective of this paper is to study the design of CR platforms making use available SDR software packages and hardware...

...Abstract The expansion of the organization has allowed the IT department to design a network that will allow each office to share the same Internet Domain Name while still being located in separate offices. The organization currently own 25 servers and they expect to have to purchase up to thirty more to accommodate the new branch office. The design will allow for providing service to 5000 users with the thought of future growth being applied to the new network design. It has been suggested that certain resources are to be centralized which would help to reduce costs. With all of this in mind, the team came up with the necessary design while trying to keep costs down to a minimum. Quantity of Connectivity Equipment In order to successfully link all of the new branches there will be several connectivity devices that are required. The design for the organization will need to include seven new branch offices in five states; each branch office will consist of five floors each. This expansion of the company will require the company to purchase several new hardware connectivity devices in order to ensure that the expansion is successful. In order to do this I would recommend that each branch is equipped with five switches, one for each floor. This will require thirty-five switches total for all of the branches. Each floor will be set up as a small network with permissions to connect to each of the other floors in the branch. In addition to the switches...

... business and social interactions, and Internet access no longer depends on a wired system such as a modem connected to a telephone landline, but rather, it can be achieved using a mobile enabled device whenever and wherever a mobile access point is available. Such access points or hot spots are now widely available in airports, hotels, educational institutions and other public buildings, and increasing numbers of wireless networks are being installed in commercial buildings and private homes. The term "wireless" refers, in the most basic and obvious sense, to communications sent without wires or cables. It is a broad term that encompasses all sorts of wireless technologies and devices, including cellular communications, networking between computers with wireless adapters, and wireless computer accessories. Mobile technology extends computing and the Internet into the wireless medium, and provides greater flexibility in communication, collaboration, and information sharing. Mobile technology, which can support computing on the move using portable devices through wireless networks (Varshney and Vetter, 2000; Malladi and Agrawal, 2002), has emerged as the next wave in IT revolution.

...Introduction Wireless internet has now become a way of life. It is all around us. Our society has now moved from the ability of being linked by a cord to access the internet to the availability of accessing the world wide web by using wireless capabilities. The way we receive news and media has changed since the invention of wireless. This technology has become so common that one may rarely think about it at all when using it. The days of plugging up a computer to an Ethernet cord to be connected to the internet has become a thing of the past. Surely this method is of course still used, but it has become a less modern way to connect to the World Wide Web. When you want to see what the weather forecast will be in your area, it is as simple as opening up your phone and punching in your zip code. It has also made the ability for ratings to be gathered for televsision shows using netowrking sites such as twitter and facebook. These sites can be access through wireless on mobile phones (Spangler, 2011). Presently more applications are being developed that allow the use of wireless internet. These applications can be downloaded for celluar phones, tablets, ipads, and ipods. One application that I have used is an application called Kazzam. This application is truly amazing and I has been helpful in several situations. Have you ever heard a song that you loved and could not get it out of your head?

...Networks, Telecommunications, and Wireless Computing | | | Telecommunication systems enable the transmission of data over public or private networks. A network is a communications, data exchange, and resource-sharing system created by linking two or more computers and establishing standards, or protocols, so that they can work together. Telecommunication systems and networks are traditionally complicated and historically ineffi cient. However, businesses can benefi t from today’s modern network infrastructures that provide reliable global reach to employees and customers. Businesses around the world are moving to network infrastructure solutions that allow greater choice in how they go to market—solutions with global reach. These alternatives include wireless, voice-over internet protocol (VoIP), and radio-frequency identification (RFID). | | | | | Knowledge Areas | Business Dilemma | | | Business Dilemma Personal sensing devices are becoming more commonplace in everyday life. Unfortunately, radio transmissions from these devices can create unexpected privacy concerns if not carefully designed. We demonstrate these issues with a widely-available commercial product, the Nike+iPod Sport Kit, which contains a sensor that users put in one of their shoes and a receiver that users attach to their iPod Nanos.
