...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...

The facility is owner operated with six employees and one location that provides a number of services to the public and area optometrist. This includes partnering with an optometry therapist to provide a full array of eye care services for pre and post eye surgery patients. Also included in this paper are short definitions of Rotary and Dual Tone Multifrequency (DTMF), Wide Area Telecommunications Service (WATS), Private Branch eXchange (PBX), and The layers of the International Organization for Standardization-Open Systems Interconnection (ISO-OSI), telecommunication terms as the relate to this business. Gaining permission to view and evaluate the telecommunication systems of a small family owned and operated business when you have been working there less than a week can be a tricky matter. I began by explaining that my interest in the system is purely school related. I continued by letting him know that the conversation and information exchanged could assist in developing a more effective system for the business. This helped but, skepticism and caution were still the overriding view of Doctor Martin business owner and board certified ophthalmologist. Ensuring the privacy of his business records appeared to relax him a bit as did telling him that I did not want any defined information just general. Telling him that I was...

...1.0 Introduction Telecommunication is very important in the social and economic empowered both for developed and developing countries. 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. The historical perspectives of how reforms have been achieved will the area of concern in this review. 2.0 Czech Republic ...

...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...

...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...

...Network Management and Security (Name) (Instructors’ name) (Course) (Date) Network Management and Security A telecommunication Management Network, commonly known as TMN, is an infrastructure that provides interfaces for connection between several types of operating systems and telecommunications equipment, so as to manage the telecommunication service and network. This is from Glenn Warnock and Nathoo Amin (215). Also, it enables the functioning of the management information, which is exchanged through these interfaces. On the other hand, 5620 SAM is widely used for developing distributed systems, as it provides the infrastructure for interoperability of several object oriented management applications. With this application, the 5620 enables applications of operating systems to interoperate with the service access manager, allowing it to provide connections, isolate and manage network issues across an Alcatel network (225). With this, users can access management information transparently and independent of the hardware and software platform. This therefore enhances the portability of applications, which are developed across the multiple platforms of management. The principles and concepts of the TMN that can be matched with the features and functions of the 5620 platforms include the specification translation and the interaction translation. Redundancy is also an important feature. It is the automatic transfer of data network to stand by, and protects the...
