...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...

For a very large size company like Public Bank Group, the best type of telecommunication network should be WAN. WAN is an acronym for wide area network. WAN coverage large geographic area such as a state, province or country. It often connects multiple smaller networks, such as local area networks (LANS) or metro area network (MANS) by using private or public network transport. WAN can be said that it is the most popular networks in this world nowadays. WAN is actually same as the internet that we are using right now. Businesses and government entities utilize WAN to relay data among employees, clients, buyers, and suppliers from various geographical location. This kind of telecommunication network allows Public bank group to effectively carry out its daily function regardless of location since public bank has so many branches in different location. The main advantage by using WAN is it provides the facility to communicate in long distance for the purpose of sharing information too. Public Bank uses this network to share the customer profile and other financial transaction information among different branches. It allows Public group branches to...

...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...

Most of young generation has the latest mobile technology, such as laptop, IPhone or blackberries.. Telecommunication system enables transmissions of data over public or private network…business can benefit from today’s modern network infrastructures that provide reliable global reach to employees and customers (Baltzan & Phillips 2007). Mobile marketing is very important because of millions of people around the world exchanging text message or use multi-media service to each other. By utilizing the popularity of text message or mobile coupon, we can convince mobile user customers to switch to our product. The café needs to use mobile technology to extend its marketing by offering mobile coupons its customers. Mobile coupons allow café customers to get instant redemption coupons on their cell phone. As customer walk past the café (or within a 25 foot radius of the café) a coupon for a dollar off a latte or a 15% off discount on an order will be sent to customer’s mobile device. (Cohension Case). Customers can simply bring their cell phones to the café to redeem the coupon electronically. M- coupon is much better than traditional paper coupons for many reasons. First of all, it provides great convenience to customers. Customers do not have to worry about cutting the paper coupon from newspapers or magazine to carry with them for future use. It...

...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...

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...

...I have learned a lot from this class about management and organizational behaviors, and will carry these things with me through my career. The things I have learned in this class about how to manage people and business will further my education and knowledge of the managerial world. 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. The four step process that doesn’t have any kind of organization as to which ones a manager must do first or last or in between spells out the acronym C.L.O.P. The first letter of the management process is C. The letter C stands for Controlling. Controlling is the process of measuring work performance, comparing results to objectives and taking corrective action as needed (Schermerhorn, 2012). Control is a necessary quality for a manager to have so that he can make sure all of his employees and co-workers stay on task and don’t fall behind with their work. The second letter L stands for Leading. Leading is the process of arousing people’s enthusiasm to work hard and inspiring their efforts to fulfill plans and accomplish objectives (Schermerhorn, 2012). Leading is an important quality for a manager to have so that while controlling their employees to get...

...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...
