CONCLUSION
REFERENCES I. Introduction
The current design consists of an Intel personal computer with Windows 7 as the operating system and accessing Internet services at 56 kbps modem speeds. The objective is to upgrade to a faster solution through the use of Ethernet Cable and Wireless 802.11n; deploy properly a Local Area Network using the necessary technology, hardware and software specifications, appropriate protocols and group policies; and combined wired and wireless communications to include Internet services provided by an Internet Service Provider.
Overview
The incorporated network consists of workstations, printer, scanner, fax and copier bundle; telephone capabilities; server management and protocols. The network would be configured to manage users, files, folders and printer sharing options to include a well implemented security system to prevent intrusion of cyber threats such as unauthorized users, viruses and spillage of information.
A client-server oriented local area network architecture allows for easier and centrally administration of clients and to provide better reliability, top performance, and cost-efficiency a star topology must be implemented as the layout of the network. The server side of the client-server model offers several features that can facilitate the management of nodes such as Remote, and file-printer server capabilities to include data backup. The clients in the client-server layout can access and store files and folders in the server which can be shared by all workgroups.
Internet capabilities are provided by a top Internet Service Provider, Comcast offers bundle packages composed of Internet, Business E-mail, phone and television at low prices. Each bundle package offers telephone services and a variety of features intended for high speed internet connections, for instance, Web Host package, Wireless services, Telecommuting, unlimited data allowances and speeds ranging from 3 Mbps to 150 Mbps for upload and download of data, as well as unlimited local and domestic long distance calls.
To successfully attain network connectivity, appropriate hardware and software must be correctly installed from cables, hubs, and adapter cards to configuring IP addresses, applications and drives; Group policies and protocols must be establish correctly following business rules; needed applications are safely uploaded to attain corporate communications required between staff and consumers.
Network Architecture
The success of the network lies on three major tasks: i. The constant communication between nodes with minimal to no loss of packages. ii. The access of data needed in a timely manner by clients to carry out the required business. iii. Proactive administration of network nodes identifying shortcomings and security breaches promptly. To attain such outcome, all data must be stored and accessed by network clients - computers, printer, and faxes - from a centralized host standing as a server. In addition, network clients must have the capability of sharing folders and files with other network clients using peer-to-peer communication therefore preventing overloading the server and finally every protocol and group policy must be set properly to allow the authentication only through the use of proper credentials. The network configuration consists of Intel computers with Windows 7 operating system, an all-in-one printer, copier, fax and scanner, VoIP telephones, and hub, routers and switches connecting all end systems to one main computer serving as the main server. All nodes connect to each other by using approved cable and connectors. A star topology can provide for better data transfer results; it offers the possibility to easily replace malfunctioning components without a full network shutdown; and it allows for future expansion of the network. While minimizing the possibility of a fault which could bring the network down it requires more cable to connect all end-systems and

Cabling and Connectors

A necessary component to ensure all devices work properly in a network is the cables and connectors that join these devices. The number of cables and connectors needed is determined by the amount of devices that compose the network, each device requires a cable and connector. The maximum required length for Ethernet 10 Base-T and 100 Base-T is 100 meters with no cables being shorter than three feet long. The quality of network cabling and connectors also is a key element to ensure a good connectivity. Ethernet cables should be rated as Category 5 (Cat 5) or better (Cat 5(e), Cat 6, and Cat 7) provide better connectivity. It is imperative that the cables are purchase from a local computer store this ensures cables can be returned if they are defective. As for connectors the RJ-45 twisted pair cable or patch cable is the standard connector. Normally, the multifunction printer, VoIP Telephone, Desktop and other devices have the necessary cables included such as power cable, USB cables, and adapter cables.
Security

Security software vary from vendor to vendor and carry many essentials for the protection of computers and laptops. One example is McAfee which provides protection against virus, spyware and web threats. Other security software vendors include Symantec, Trend Micro, Kaspersky and ESET. A secondary measure is to ensure no unauthorized user gains access to information stored in a desktop, laptop or server is through the use of a Username/Password combination. Window Server 2012 fully installed in Dell PowerEdge T-110 II provides several features and technology that helps protect the integrity of the network. These include protection of user security group and authentication policy silos adding more credential protection; BitLocker encryption methods; encryption of hard drives and network unlock features. Also, smart cards sign-in services; identification of programs running on domain computers to control the ability of those programs to run. These are only a few of the security capabilities offered by Windows Server 2012. D-Link DIR-655 Xtreme N Wireless Gigabit Router allows encryption using 128-bit Wired Equivalent Privacy (WEP) and 64-BIT Wired Equivalent Privacy (WEP) algorithms and security protocols and security certification programs Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA-2).
