1. Describe a local land line phone system on the following Landline Telephone Components: a. Local Loop: A local loop is a network or circuit that connects a group of telephone customers to the edge of the service provider’s network, no larger than 3 miles. b. Central Office: A central office is responsible for providing certain services to the local loop, such as, call routing, signaling, digit collecting. c. Local Exchanges: A system of devices or switches that direct local calls. Commonly called a switchboard. d. POP: POP (Point of Presence) is the location or interface point of a communicating party. Comparable to an internet POP such as a router or switch. e. Long Distance System: The long distance system is a service for making long distance calls. Before direct dialing, this was done though several switchboards spanning many different areas. f. Fixed Line: A fixed line, also called a landline, is a telephone that is physically connected to the local loop via telephone line. This differs from a cellular phone which uses radio waves to connect. 2. Define and describe the following Telecommunications Network Components: g. Cellular Telephones: Cellular Telephones use radio waves to communicate with cellular towers that direct the call. They currently use 3G and 4G connections for both voice and data. i. Voice: Voice calls are not too unlike fixed line calls; the difference being that is it transmitted wirelessly. The call is transmitted via radio waves to a cellular tower, which is then routed through the service provider and to the party on the other end. ii. Data: Data is commonly called “mobile internet”. Data is sent through radio waves in either a 3G or 4G connection, which streams data to and from the phone, much like a computer connects to the internet. h. Telephone Network…...

...Networking When you have two or more computers connected to each other, you have a network. The purpose of a network is to enable the sharing of files and information between multiple systems. The Internet could be described as a global network of networks. Computer networks can be connected through cables, such as Ethernet cables or phone lines, or wirelessly, using wireless networking cards that send and receive data through the air. LAN - Local Area Network A LAN connects network devices over a relatively short distance. A networked office building, school, or home usually contains a single LAN, though sometimes one building will contain a few small LANs (perhaps one per room), and occasionally a LAN will span a group of nearby buildings. InTCP/IP networking, a LAN is often but not always implemented as a single IP subnet. In addition to operating in a limited space, LANs are also typically owned, controlled, and managed by a single person or organization. They also tend to use certain connectivity technologies, primarily Ethernet and Token Ring WAN - Wide Area Network As the term implies, a WAN spans a large physical distance. The Internet is the largest WAN, spanning the Earth. A WAN is a geographically-dispersed collection of LANs. A network device called a routerconnects LANs to a WAN. In IP networking, the router maintains both a LAN address and a WAN address. A WAN differs from a LAN in several important ways. Most WANs (like the Internet) are not owned by...

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 faces that due to its large network because as much as the network is large or wide it is not easy to handle it. As the Wireless Local Area Network is large and complex network......

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.

...1. Choose a topic. If you are lucky enough to be able to choose your research topic, pick one that interests you. The last thing you want is to end up spending hours learning and writing about a subject in which you have zero interest. You will find the whole process much more enjoyable if you actually care about what you are doing. [1] * Be sure to stay within the guidelines you are given by your teacher or professor. For example, if you are free to choose a topic but the general theme must fall under human biology, do not write your essay on plant photosynthesis. * Stick with topics that are not overly complicated, especially if the subject is not something you plan to continue studying.

Course Project Week #: 2 Networking in My Life and Career A network is defined as a group of computers that are connected to share information. An NIC is a Network Interface Card. It is the physical component of a computer that allows a computer to connect to a network. Three types of media used for network connections are cable television coaxial, fiber optic cable and wireless connections. There have often been times when I have had to access my home wireless internet network and have not been able too. I start to troubleshoot by disconnecting and re connecting to the wireless network in the Open Network and Sharing Center. If that does not work, I check my wireless router to see if the lights on the router are green indicating that it is working properly. If there is a red or orange light on the router, I unplug the power source of the router and let it reset. This usually resolves the issue. My career goal is to become a Network System Administrator. That being said, I will be dealing with networks on a daily basis. A Network System Administrator is responsible for designing, installing, maintaining and upgrading networks in businesses of different sizes. I still have not taken any networking classes.

And she has thought about going on a cold turkey but that will make her so uncomfortable, and she knows that she can not do it. Joanna Lipari is a clinical psychologist at the University of California. She says that social networking is like the movie “The Truman Show” with Jim Carrey a movie about a fabricated world where nothing goes wrong. And it is the same with Facebook. People only use Facebook to present the crème de la crème of their lives on Facebook. When you are addicted to Facebook you stay up late on Facebook even though you are tired, if you use more than an hour on facebook, if you become obsessed with old loves, if you ignore work in favour of Facebook and if the thought of getting off Facebook leaves you in a cold sweat. 2.

Social networking is the grouping of individuals into specific groups, like small rural communities or a neighbourhood subdivision. Social networking is also possible in person, especially in the workplace, universities and high school as well.

...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......
