• What are smart phones? o A smart phone is a device that was introduced after the basic phone was used.The usual cell phone was used to make and receive calls. A smart phone as the ability to make and receive calls, send text messages, and browse the web. Web browsing has become more popular with the increase of speeds from cellular networks. No one wants to sit with their blackberry curve and browse on 2G. As soon as 3G came around, there was a large increase in the usage of smart phones also and now, moving forward with LTE/4G as well.
• What changed from 1G cellular technology to 2G technology? o The main thing that changed from 1G to 2G technology was the ability to send SMS and MMS messages. 1G technology speeds were below10kbps. I cannot even imagine data that slow. I think most people if they were trying to browse with analog speeds would just give up.
• Compare typical 2G speeds with 3G speeds? o Typical 2G speeds are about 10kbps, the data speeds received on 3G are Typically provide speeds of 300 to 500 kbps. However, when dealing with mobile devices, you’re also factoring in many variables. For one instance, environment. When using wireless cards or cellphones while browsing, you will not always receive the same data speeds wherever you go or all during the year. Sometimes during fall, the foliage is prevalent, and it weakens signal strength to cell towers. It can depend on the structure of your house, and whatever structure is between you and the nearest connected cell tower.
• What are likely to be typical download speeds for early 4G systems? o Currently the speeds for 4G are still far higher than 3G, but are not as high as 4G will become to be. The current speeds are around 3-5 Mbps.
• What speeds will 4G support eventually? o Download speeds for a typical 4G user, would be from 1Gbps for a stationary user and 100 Mbps for a user on the…...

...Networking Concepts and Applications Week 1 Homework : Questions Question 7: How do local area networks (LANs) differ from metropolitan area networks (MANs), wide area networks (WANs), and backbone networks (BNs)? One of the key differences between different network types is their geographical scope. A local area network, or LAN, is made up of a smaller group of computers linked together and located in the same small area such as a room, a floor or a building. A backbone network, or BN, is a larger network which connects multiple LANs, WANs, MANs or other BNs together and can range from a few hundred feet to miles in size. Metropolitan area networks, or MANs, normally range in size from a few miles up to thirty miles and LANs and BNs from different areas to each other as well as to WANs. Wide area networks, or WANs, can be hundreds or thousands of miles in size and connect MANs and BNs across these distances. Question 14: Explain how a message is transmitted from one computer to another using layers. The message is first created at the application layer using a software application. This software translates the message based on the protocol being used to transfer the message and places the necessary information along with the message into a Protocol Data Unit (PDU) which is also known as a ‘packet’. This packet is then passed on to the Transport Layer. The transport layer, using its own Transmission Control Protocol, or TCP, takes the packet from the......

...Richard McMaster INF325: Telecommunications and Networking Concepts Week 2 Answer the following “Test Your Understanding” questions using APA style and form: a. Below what speed are there different leased line standards in different parts of the world? Difficulties start below 50 Mbits of data so different countries have different lease line standards. b. What is the exact speed of a T1 line? A T1 line is a lease line in North America. This connection is a dedicated connection that can support up to 1.544 Mbps based on a digital signal on 24 channels at 64 Kbps. c. What are the speeds of comparable leased lines in Europe? The comparable lease lines in Europe to a T1 in North America can support up to 2.048 Mbps. The network structure is similar yet still different from the network setup of North America. d. Why are fractional T1 and E1 speeds desirable? Fractional T1 and E1 speeds have a large effect on costs, efficiency and use. The use of these dedicated lines is dependable and consistent and mainly used by companies and/or individuals who require a dependable access to the internet. e. List common fractional T1 speeds. Fractional T1 speeds include 128 kbps, 256 kbps, 384 kbps, 512 kbps, 768 kbps. f. What are the most widely used leased lines? The most widely used leased lines would be T1 and E1 and Fractional T1 and E1 lines g. What leased line standards are used above 50 Mbps? Above 50 Mbps is when the SONET/SDH......

Networking Technology Concepts

...Networking Technology Concepts Capella University Abstract The purpose of my paper is to explain the concepts of networking technology and what impact these concepts have in an organization. A number of these concepts embody, but are not restricted to, improved communication, enlarged productivity, and enhanced mobility. In addition, what part does network architecture play in developing network technology? In doing thus, I will be able to justify the aim and role that standard-setting organizations play in establishing network standards and identify two standards in network technology and outline their roles. Explain the importance of the ISO (International Organization for Standardization) and show how they contribute to the advancement of the network industry. Keywords: technology, ISO, networking, architecture, concepts Networking Technology Concepts The basic concepts of networking technology are to improve communication, increase efficiency, and enhanced mobility. In addition, network architecture falls in line with these concepts because architecture is the foundation or the framework to configure networks. Improve Communications Technology is important because it expands communications in the workplace. Employees are no longer limited to using regular landline phones, couriers or snail mail. Technology has evolved tremendously whereas, you are able to start communicating electronically using computers, smartphones and other forms of electronic devices......

...MAN also depends on communication channels of moderate-to-high data rates. This network is usually owned and operated by one company, but used by many other companies or organizations. d) Campus area network/ Corporate area network (CAN) This network is made of an interconnection of local area networks (LANs) within a limited geographical area. The networking equipment’s (switches, routers) and transmission media (optical fiber, copper plant, and Cat5 cabling) are almost entirely owned by the campus tenants/ owner. The university, government or an enterprise. There are a lot more modes of communication such as GPS (Global Positioning System), MMS (Multimedia message sending), Satellite systems for live communications. 5) OSI and TCP/IP models both share similar architecture. They both are constructed with layers. The application layers are the same, but the services maybe different depending on the model. The functions that are performed at the presentation and networking level, similar functions are performed the transport layer of the TCP/IP model. According to information gathered from the internet, a networking professional must be knowledgeable of both OSI and TCP/IP. Both models individual packets may take different paths in order to reach the same destination. The differences are that TCP/IP protocols are considered to be standards around in which the internet is developed. For this reason, it is also considered to be a more credible model than the......
