I. Definition of the subject
Telecommunications technology is defined as physical devices and software that links various pieces of hardware and transfers data from one physical location to another. Computer networks consist of two or more connected computers that carry information across a wired or wireless technology. The basic hardware needed for the network to operate is a router which directs traffic to different computers and a network card which allows the computers to communicate. These networks include computers, internet services and communication tools which include cell phones, video conferencing, and email. The internet includes the World Wide Web, chat, email, and voice over internet protocol (VoIP), unified communications, and virtual private networks (VPN). Definitions of each term are defined below.
• World Wide Web is the most popular internet service.
• Chat allows individuals to “talk” live holding and interactive conversation.
• Email allows messages to be exchanged from person to person within seconds. It is faster and less expensive than any other delivery method such as the postal or overnight delivery services.
• Voice over Internet Protocol (VoIP) allows users to send calls using broadband internet. It allows users to avoid long distance and toll charges normally charged by local companies. “VoIP can reduce communication and network management costs by 20 to 30 percent.” (Laudon, 2010, p. 269)
• Unified communications encompasses all forms of communications that are exchanged via the internet.
• Virtual private networks (VPN) are a client base application that allows high speed access to network services through a privately provided cable modem.
In today’s business world, telecommunications, networking, wireless connections, and telecommuting is an absolute must in order to run a highly competitive and successful

Network & Telecommunication Concepts

...Running Head: Week 1, Individual Assignment; TCP/IP Architecture and OSI Layers TCP/IP Architecture and OSI Layers [your name here] NTC360 Network and Telecommunications Concept Associate Professor Anthony Bruno January 04, 2011 The purpose of this paper is to describe an OSI (Open Systems Interconnection) Model with details about each of the seven layers. The OSI reference model adopts a layered approach, where a communication subsystem is broken down into seven layers, each one of which performs a well-defined function. Additionally it is important to understand the purpose of the OSI model in the overall networking architecture especially as it relates to the TCP/IP (Transmission Control Protocol/Internet Protocol) Architecture, which also consists of layers each playing a particular role in the networking design. Generally speaking, the network protocol layer, which is similar to the data and network layer of the OSI model includes the protocols that allow clients and applications to send data over the network. This includes TCP/IP, NWLink (IPX/SPX), NetBEUI, Infrared Data Association (IrDA). However, the purpose of this document is to focus on the relationships between the OSI model and the TCP/IP architectures, and how they may interact together. Finally, as demonstration of this relationship a visual diagram has been provided to depicts how the TCP/IP layers correspond to the OSI model and layers. To begin with...

Telecommunication Industry.

...Telecommunication Industry. Communication networks in the digital world make possible joint production of a range of different services for a diverse group of customers. In the case of telephony, technological development has increased economies of scope far beyond joint production of voice and fax connection. For most calculation purposes, this means that the old costing systems and allocation assumptions stemming from the days of national voice telephony simply do not offer relevant facts any longer. This is true for internal decision making in the telecommunications, but perhaps more importantly for setting interconnection charges. Activity Based Costing (ABC) is an alternative to or improvement of previous costing practices. The activities in telecommunication network can be process steps and switching. For example, a long distance call passes by several switching processes. In this case, we can calculate cost per switching following the call time and distance used by subscriber. In the central process steps in telecommunication network, cost varies according to traffic. Call consists of switching, connection before call, and call connection. In this operating level, cost driver is the number of switches in switching process and the time to call in channel and transmission process respectively. Activity Based Costing (ABC) is an alternative to or improvement of previous costing practices. The activities in telecommunication network can be process steps and switching...

The government must be able to promote growth of vibrant telecom sector. However, most of the governments seek to come up with methods of ensuring that there is an independent telecoms regulator. Communication infrastructure reforms are a concept which enables operators to offer quality services. Infrastructure sharing is one of the reforms that can take place. It refers to the ability of operators to share networks or the ability of one party building communication infrastructure that will lease to other providers. Communication infrastructure can be done in fixed, mobile and broadcasting networks, and it is one of the best options of bringing reforms and best practices by bringing competitors in the industry to collaborate with an aim of lowering the cost and increasing their capital. It is also a method of reducing the risk of proliferating network deployment. There can be active or passive communication infrastructure sharing. In active sharing, the active network and components are shared by the operators. The regulator is aimed at providing clear directions towards achievement of national and regional development goals. This paper looks at the reforms of three countries, Czech Republic, Botswana and Liberia.

...Telecommunication While traditional telecommunications networks have allowed us to cross barriers associated with time and distance, the new multimedia realm is allowing us to include vital physical cues in the information stream, introducing a physical reality into the world of electronic communications, goods, and services. Not surprisingly, some of the industries that are being most radically revolutionized are those that deal with the human senses, including entertainment, health care, education, advertising, and, sadly, warfare. Simply put, technology changes your way and pace of life. In recent years, the word telecommunications has been used so often, and applied in so many situations, that it has become part of our daily lexicon, yet its definition remains elusive. So, let's start with a definition. The word telecommunications has its roots in Greek: tele means "over a distance," and communicara means "the ability to share." Hence, telecommunications literally means "the sharing of information over a distance." Telecommunications is more than a set of technologies, it's more than an enormous global industry (estimated to be US$2.5 trillion), it's more than twenty-first-century business and law that is being re-created to accommodate a virtual world, and it's more than a creator and destroyer of the state of the economy. Telecommunications is a way of life. Telecommunications affects how and where you do everything—live, work, play, socialize, entertain, serve, study...

How to speak to people is one of the most important things to know how to do as a manager. The three things that I have will remember from this course is the management process (CLOP), the steps in the decision making process, and the small business life cycle. I believe that if I remember these three things specifically I will do well in my career.

Ntc 360 Network and Telecommunications Concepts

...NETWORKING Networking Paul F. Scheelk NTC/360 Network and Telecommunications Concepts Instructor: Anthony Bruno University of Phoenix 1. What is the range of usable IP addresses for the following IP subnet? What is the broadcast address for the subnet? 10.150.100.96/27 The range of usable IP addresses is 10.150.100.97 – 10.150.100.126. The first and last addresses are not usable and cannot be assigned to hosts as one is used as the broadcast address, 10.150.100.127 and 10.150.100.96 is the address for the sub network. When initially determining the usable addresses the /27 provides the information that the first 27 bits are network and the remaining 5 are host addresses. The subnet address would be 255.255.255.224. 2. Describe and explain the difference between circuit bandwidth and network throughput. Focus on networking. Communication networks using Ethernet or other protocols distinguish throughput as the average rate of successful packet delivery over a communication channel. The information is passed over a physical or logical link such as Cat5, 5A or 6 or media such as coax and fiber. It is also measured over a wireless network. It is usually measured in bits per second (bit/s or bps), and/or data packets per second or time slot. Throughput is the actual speed that the data is being transmitted. Bandwidth on the other hand is the maximum speed in which packets can be sent or received. Bandwidth is almost always a higher rate than throughput. 3. Research...
