...The telecommunications industry is growing at a very rapid tempo. The number of people who need to communicate is increasing with time, as well as, how fast they need to communicate. Thus, organizations and businesses are utilizing the Internet, intranets, and other telecommunications networks to support their business operations. Here are a few key points which will help understand networking and the need for telecommunications within a business structure. Telecommunication Networks A telecommunications network is an assortment of terminals, links, and switches which connect to enable telecommunication between users within the structure of network. Telecommunication networks can be defined as computer networks, the internet, and telephone networks. Telecommunications networks enable managers and end users to electronically exchange data and information anywhere in the world with other end users, customers, and even vendors. The use of telecommunication networks work in partnership innovatively, manages their business operations and organizational resources more efficiently, and stays current in the ever so changing networking industry. A good example of a how a telecommunication network works is the Open Systems Interconnect reference model (The OSI model). The OSI model divides network traffic into a seven layers. Each layer is independent, and all layers builds on the services provided by the layer below while providing new services to the layer above. Below you will......

...LAN (WLAN) is being very helpful to connect the more than one devices and it provides the easy internet connection. So that more than one or two PCs (Personal computers) can be connect to Wireless Local Area Network to ease in providing internet connection. PROBLEMS TO RUN MORE THAN ONE PCs ON A WIRELESS LOCAL AREA NETWORK: If a girl wants to connect her four PCs with Wireless Local Area Network then she has to face several problems: LOW SPEED OF INTERNET: The first problem that she faces will be low speed of internet so she will face the problem in running her business that she will have great problem in opening her mail and receiving her important mails and documents regarding to her business. The interference of the signal is the major problem of the low speed of internet. Wireless network may interfere other radiations or network working in the house. Such as radio signals may interrupted by this networking due to which not only internet signals will be reduced but also radio signals will also be affected. And her computer may be infected by internet worm so the speed may slow. Speed of Internet also dependent to the service provider. As the connections are directly related with the speed. The greater the number of connections connected, greater will be distributions of the signals, hence more time will be consumed. So speed will be slowed down. It is much slower than the wired networks. She will be handled more carefully. LARGE NETWORK: Next problem she......

...Julie Cason Networking Essnls II March 5, 2012 WAN/LAN Description Assignment The first part of this assignment is to describe the infrastructure of a network. The infrastructure is the hardware that enables computers to communicate with each other. My infrastructure is based on a star topology and can go from a LAN to a WAN very easily. I will begin with the type of cable that will be used to wire and connect my network. The cable I will use will be an Ethernet, coax interface also known as 10-base-2.The computers are connected to make a chain (like a star) and the coaxial 50ohm cable connects each “T” to the “T” on the next computer. The next technology that I will use is a hub/router. The hub houses a separate connection to each computer on the network. Any data entering the hub on one of the cables connected to it is repeated out onto all other cables connected to the hub. From there, it is then sent through a server and gateway. The gateway is tied into the Active Directory of all the computers on the network. From the server/gateway, it then goes into a Main Switch. The switch examines each arriving data packet and finds the packet's destination address. It then only sends data out to the port associated with that address. This cuts out a lot of needless network traffic and thus is why it is so important to have on a network. Finally, on my network is a Bridge. All computers end up connecting to the same wire and so they have to wait for silence on the network......

Business Networking

...Business networking is a socioeconomic business activity by which groups of like-minded businesspeople recognize, create, or act upon business opportunities. A business network is a type of business social network whose reason for existing is business activity. There are several prominent business networking organizations that create models of business networking activity that, when followed, allow the business person to build new business relationships and generate business opportunities at the same time. A professional network service is an implementation of information technology in support of business networking. Many business people contend business networking is a more cost-effective method of generating new business than advertising or public relations efforts. This is because business networking is a low-cost activity that involves more personal commitment than company money. Country-specific examples of informal networking are guanxi in China, blat in Russia, and Good ol' boy network(US)/Old boy network(UK). In the case of a formal business network, its members may agree to meet weekly or monthly with the purpose of exchanging business leads and referrals with fellow members. To complement this business activity, members often meet outside this circle, on their own time, and build their own one-to-one business relationship with the fellow member. Business networking can be conducted in a local business community, or on a larger scale via the Internet. Business......

...NETWORKING (Author’s name) (Institutional Affiliation) Telecommunication networks and OSI Telecommunications network is an assemblage of links and connecting points where several lines join together which are capable of conveying data, visual and audio activities of conveying information. Besides, audio connectivity, it also includes internet, forms of telephony and wireless equipment. Telecommunication network serve to provide efficient transmittance of data from original point to destination point, for example, a telephone call. Usually, the process that allows users to act together in a real time manner takes place within seconds. Public switched telephone network, internet and private computer networks are common forms of telecommunicating network. These are used in voice and visual communications and in businesses. A telecommunicating network is made up of terminals, computers, links, equipment and software of telecommunication. These are important in accessing the network, channeling transmitted information and regulating conveyance of messages over networks. Telecommunication network can be set up as wide area network which allows for reliable and controlled transmission of information between nodes that are geographically distant. This network model is used by most businesses across the world. Local area network provides more secure same information as in a wide area network on a small geographical area. It provides......

...were narrowly used by important personnel like military bases so they can maintain connection with their traveling co-workers, keeping them safe, and giving them direction. These networks were not connected to the Internet, as we know it. They were just basic networks for the sake of communication. Networks became much more widely used in the 1990’s when the internet emerged to the masses. Now corporate offices and residential homes alike could start a network of their own so they can to connected to whatever they like. The importance of networking was realized very quickly, the number of networks rose at a rapid pace, and today there are billions of people connected to each other in different ways. Whether it be in a small corporate office connecting employees, or the network that connects a business to its manufacturer in China, its very obvious that the network changed the world, and helped it prosper. In this paper I will discuss every networking feature in the Windows operating system as well as its importance to the network. Importance Of A Network Now that it is common for a household to have multiple devices with the ability to connect, networks have become more important than ever. Computers are no longer used just for basic communication like e-mail. These days the daily usage of a computer seems like a life requirement. People are using them for work, entertainment, and shopping, all of which most likely need a network for access. Its almost easier to ask what......

...and recapture some of the interpersonal cues that have been filtered out by the medium. Ultimately, the digital conversation lacks the spatial and temporal rules that govern embodied conversation, creating ambiguity and uncertainty for the users. How is context created and interpreted? How is conversation initiated and maintained? What function does it serve? How does searchability affect the ways that online users perform conversations? These are some of the questions that this paper attempts to answer by focusing on the conversations on Facebook, an online networking site. Facebook is an online networking site that allows its users to create detailed personal Profiles that link with other users. Features such as photo posting, commenting on other users’ “Walls,” and joining groups relating to a shared interest also form a large part of the Facebook experience. Facebook distinguishes itself from other social networking sites like Myspace and Friendster because its participation is determined by offline social networks. Initially requiring membership in a university community, Facebook more recently includes members from specific high schools, regions, and companies. Social browsing is limited to the Friends that the user lists and people from the user’s offline community (e.g. a university or city). Users can manipulate their Profile’s privacy settings to control access to their entire Profile, photos, wall posts, and other social information. Facebook has become a huge......
