...Term paper of computer networking (Design wireless network) x.y.z. Abstract: this document tells us about wireless network and various techniques to design a computer wireless network Keywords—wireless networks, connecting devices, switches, hubs. [pic] Campus network A campus network is a computer network made up of an interconnection of local area networks (LANs) within a limited geographical area. The networking equipments (switches, routers) and transmission media (optical fiber, copper plant, Cat5 cabling etc) are almost entirely owned (by the campus tenant / owner: an enterprise, university, government etc). In the case of a university campus-based campus network, the network is likely to link a variety of campus buildings including; academic departments, the university library and student residence halls. [pic] | | | | Introduction A computer network allows sharing of resources and information among devices connected to the network. The Advanced Research Projects Agency (ARPA) funded the design of the Advanced Research Projects Agency Network (ARPANET) for the United States Department of Defence. It was the first operational computer network in the world. Development of the network began in 1969, based on designs developed during the 1960s. For a history see ARPANET, the first network .

...servers and peer to peer (P2P) networks. There are many ways that computers connect and share information with each other. Computers today connect and share information by connecting to a network. There are several types of networks that computers can connect to, but the two most popular are local area networks (LAN) and wireless local area networks (WLAN). In a computer network, anything that a computer can communicate with can be connected to the network. Such as printers, fax machines, routers, and other computers. The internet was created in the mid 1960’s by the department of defense. At first this new invention called the internet was not available to the public. Like with every other new technology, the government officials were the only ones with access to the internet. In 1974 the design of the Transmission Control Program (TCP) made data and information sharing easier and more efficient. In 1982 the internet technology protocols were developed. These protocols worked together with the TCP to regulate and monitor the information sent/received over network. The first definition of the internet is described as computers connected to a set of networks (Mitchell, 2010). From here on out, the World Wide Web is the most sophisticated way to send and receive electronic mail, find information on any topic, and access web pages from any computer. A computer network is used to connect two or more computers together so they can share data between them. Networks are built with...

...1. You have just begun working as a networking consultant with MTI Technologies Inc. One of your first tasks is to help troubleshoot a small Ethernet network at a tax preparation office. The backbone of this network consists of six hubs connected in a bus fashion. Three of the hubs service workgroups of 10 workstations each. One of the hubs services two file servers and two shared printers. In anticipation of tax season and a heavier workload, the organization recently upgraded its network from 10BaseT to100BaseT. However, they have not seen any of the performance increases they expected. Before even visiting the firm, what can you suggest as reasons for the less than optimal performance? If one of the NICs is not capable of 100BASE-TX the entire network will operate on 10BASE-T even if all of the hubs and other NICs are capable of negotiating 100BASE-TX. If there are a large number of transceivers trying to talk at once on a hub-based network they will jam up as packet switched traffic is inherently bursty. There's a limit to the number of repeaters that can be installed between any two hosts on a hub network. There is no such limitation for switches, which is what I would recommend for the company. 10BASE-T allows for 4 repeaters between hosts, but 100BASE-TX allows for only two and only under very strict circumstances. If my initial assessment of the topology is correct, each case involves no less than 3 hubs: one for the workstation group, one for the backbone bus itself...

It also uses voice when you make a call. 2. Land phones use both networks. It uses data for caller ID and to send the information to find out where the call will be going. It also uses voice to transmit back and forth so that you can have a convocation. 3. SMS/Text messaging uses data networks. It only uses data networks because you are sending a message to another person. And in that message you can have files attached to the message as well. 4. Fax machines uses a data network. It uses this network because you put a document or photo threw the machine and it takes the image of that and creates a file. It then takes that file and sends it to another location. Then that location opens and prints or views the file. 5. Pagers use only data networks. It only uses data networks because when you send a file containing only text and then send it to a pager. The pager then takes that file and opens it showing the text for that person to read. 6. VOIP (voice over IP) uses data networks. VOIP uses data networks only because It uses the internet to talk to people instead of the traditional voice network. This allows someone to bypass the phone company.

...Chad Nash Advantages and Disadvantages of Windows XP Windows XP was introduced as a significant upgrade to Windows 98 and Windows Millennium. After Microsoft brought out MS-DOS in the 1980's it developed its futuristic operating system - Windows. Newer versions of this OS were developed over the years, including the out bringing of Windows NT (New Technology) which was aimed at business users and computer servers. After numerous incarnations of the Windows operating system, including Windows 95, 98 and the much criticized Windows Millennium, the XP system was released October 25, 2001.Windows XP has much in common with the singularities and also engineering of Windows 2000. In fundamentals XP was created to"bridge the two architectures (NT and Windows 9x--or DOS) into a single common operating system." Windows 2000 was based on Windows NT technology; as far as Millennium (ME) was created from Windows 9x technology. The NT operating system was much more honorable than the other versions before the o of Windows and accordingly Microsoft decided to choose this technology as the infrastructer for XP. XP was put out in two basic versions - The home and the professional version. The basic inequality between the two versions is that the up to speed version places more significance on security. It also has the efficiency to encrypt files and data and has support for multiprocessor systems. ( Lanyon P.) Windows XP was developed to on the problems and inconsistencies in the ME system...

...Wireless LAN is a networking technology that allows the connection of computers without any wires and cables, mostly using radio and infrared frequency (RF) technology. It's called LAN because the range targets within an office, a building, a store, a small campus, or just a house. The description of a WLAN is a mobile data communication connectivity system installed and configured as an alternative in some cases for traditional LAN. The WLAN equipment is capable of receiving and sending data over an adequate range. In the United States, the WLAN business is increasing in areas like the airports, health-care, warehousing and manufactures. Several research companies are predicting a healthy increase in WLAN business market in the coming years. The WLAN provides advantages over traditional LAN technology such as buried cables in the ground, hidden cables behind walls, and long cable runs measured in feet or miles. Without restrictions, the new technology infrastructure can easily be installed and ready to be used. Current growth concerning network communication technology in the enterprise communication environment has resulted in widespread deployment of numerous products that cover only a small part of the total mobile and WLAN infrastructure required.

...full-duplex mode. Baud transmission is the number of signaling elements that occur each second. At slower speeds, only 1 bit of information is encoded in each electrical change. When saying 1500 baud, it means that 1500 bits are transmitted each second, this is also shown as 1500bps. Communication protocols can also describe the syntax, semantics, and synchronization of analog and digital communications. Communications protocols are 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...
