The Future of Wireless Internet
Fifteen Years ago computers were just an expensive typewriter, calculator, and entertainment center thrown together in one box. People transferred their tiny files with floppy disk. The computer itself seldom had a hard drive. It was an amazing feat to dial into a computer bulletin board, and talk to other users of systems. Networking computers was more or less unheard of. The only exception were mainframes that might span several buildings, with terminals, or dial in terminals. The internet, and TCP/IP were developed by the Department of Defense so as to be able to link together several LANs around the country. Each individual system was built sometimes by different vendors, and were sometimes incompatible. For example I can remember my father telling me while he was working at Perkin Elmer that they had to link from San Diego to Cheyenne Mountain in Colorado with two dissimilar systems. TCP/IP was a robust common language that could be used.
In part the same is true today, The Arpanet is no longer the driving factor in the internet, but business. Computers using a myriad of operating systems, from a DEC to a Unix box, to someone running Windows 2000, they all can speak the same language.
Im going to overview how TCP/IP works into the entire system. Keeping in mind the OSI reference model (Fig. 1). While TCP and/or
UDP are running at the Transport Layer IP is
running at the Session Layer. The IP protocol
handles fragmentation of packets. Fragmentation
is essential, because some networks allow a very
large packet size, and others do not packets
sometimes must be fragmented. The presentation
layer is where the TCP/IP "languages" are used
such as FTP, SMTP, HTTP, a...

The internet was created to test new networking technologies developed to eventually aid the military. The Arpanet, advanced research projects agency network, became operational in 1968 after it was conceived by Leanard Roberts (Watrall, T101, 2/2). Ever since the Arpanet began in 1968, it grew exponentially in the number of connected users. Traffic and host population became too big for the network to maintain, due to the killer application known as email created in 1972. The outcry for a better way sparked the development of the NSFNet. The National Science Foundation Network replaced Arpanet, and ultimately had many positive effects. This early division of the internet spread its netw...
The purpose of this paper is to present a proposal to implement Internet Protocol version four (IPv4) also known as Transmission Control Protocol/Internet Protocol (TCP/IP) structure as our primary means of communication within our network infrastructure. We are currently using a legacy mainframe system that limits are current means of network connectivity with other evolving network systems and it is in our best interest that we look into the future as well as keep up with changing times as Information Technicians. I will present a detailed analysis of the TCP/IP brief history, understanding of IPv4 addresses, subnetting, configuration, and the benefits of using the TCP/IP structure. This will greatly increase the overall success rate of our business
TCP/IP is a network standard that defines how data is sent throughout the network. TCP/IP consists of two different layers. Transmission Control Protocol is the higher layer and manages the assembling of a message or file into smaller packets. After forming the packets, the device will transmit them across the Internet and to be received by a device that is also using the TCP protocol. The device then reassembles the packets into the original message and presents the data to the user. The lower layer is Internet Protocol and handles the...

TCP/IP operates at both levels 3 and 4 of the OSI model. The TCP portion of TCP/IP operates at level 3 (Network) as its primary function is to control the flow of data. IP operates at level 4 (Transport) of the OSI model. IP is the protocol responsible for the actual transmission of packet across the network.
Wireless local area networks (WLANs) have the potential to improve the flexibility, productivity, and the quality of work life of an enterprise (Sage Research Staff, 2001). Berean Institute is a typical two year college with about a staff of sixty eight employees and 250 students per semester. Berean teaches cosmetology, barbering and the latest software and hardware technology, which is located in Philadelphia, Pennsylvania. Berean currently has two locations in the Philadelphia area and using a Local Area Network (LAN).

Nortel Networks already demonstrated wireless applications at speeds more than 25 times faster than today's industry standard. Recently, Herschel Shosteck Associates ranked Nortel Networks first in Wireless Internet infrastructure strategy, and The Yankee Group ranked Nortel Networks first in next-generation Wireless Internet architecture.
The Internet is, quite literally, a network of networks. It is comprised of ten thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to modest PCs in people's homes and offices. Despite the recent hype, the Internet is not a new phenomenon. Its roots lie in a collection of computers that were linked together in the 1970s to form the US Department of Defense's communications systems. Fearing the consequences of nuclear attack, there was no central computer holding vast amounts of data, rather the information was dispersed across thousands of machines. A set of rules, of protocols, known as TCP/IP was developed to allow disparate devices to work together. The original network has long since been upgraded and expanded and TCP/IP is now a "de facto" standard.

The presence of computers, phones, internet and wireless devices have broadened the web of connectivity by changing long distances to short ones where everyone is equal distance from the other through the present connections. Leaving without technology will be totally impossible as this has become every day’s application as more and more people are gaining knowledge on how to make use of the communication tools to improve their ways of living and staying informed on the current technology to avoid being left behind. New technologies are being developed daily which shows that the industry will continue to grow and expand. People will continue using these technologies to improve their standards and to stay informed
In 1973, “Development began on the protocol later to be called TCP/IP, it was developed by a group headed by Vinton Cerf from Stanford and Bob Kahn from DARPA. This new protocol was to allow diverse computer networks to interconnect and communicate with each other (Kristula 1974-1983).” During its development was when the term Internet was first used. TCP/IP was adopted by the Department of Defense in 1980 replacing the old NCP and became universal in 1983. Also in 1983 ARPANET split into ARPANET and the military segment, MILNET. MILNET became integrated with the Defense Data Network created the previous year. Thanks to TCP/IP and its decentralized structure, ARPANET grew and grew during the early eighties.
The first network ARPANET was a network with several computers that performed packet switching that was used to connect to each other by modems (Edwards and Bramante, 2009. p.29). Technological advances, network evolution, and type of communications have changed, but the basic building blocks of a network remain the same. A device to communicate from, a medium of communication, and a device to communicate with. The communication devices are no longer just a big and bulky computer in a University laboratory, they vary from personal computers, smartphones, ATM machines, to supercomputers, and any numerous other devices and new inventions introduced on regular basis. Regardless of the type, these communication devices require a way to enter a network, which are network interface cards, networks hubs, and modems. These are the devices that convert the data into a signal that can be transported over the network from one communication device to another (Edwards and Bramante, 2009). The medium of transmitting the signal can be wired or wireless. A wire communication depends on copper or fiber optic wires and the wireless communications using radio signals. The internet is comprised of numerous networks that control many aspects of everyday life spanning from the energy services to utilities, to telecommunications, transportation, finance, research,
