The Management of Telecommunications: 2nd Edition Houston H. Carr and Charles A. Snyder What is Technology?What is Telecommunications? Chapter 1
Introduction • Technology can be found everywhere • It changes the way we work and live. • Technology affects our lives, but because we are so familiar with it, we hardly notice it at all.
Technology awareness • Some technologies are so ubiquitous we tend to forget they surround us.
Data and Information • Technically, information is processed or meaningful data. • Data are unprocessed. • Data becomes information when they are processed so a human can act upon them. • Data are abundant • Information, the stuff with which decisions are made, is scarce.
Telecommunications Technology • Telecommunications technology is the means that is employed to effect communications of voice, data, and image over a distance.
Telecommunications technology devices • Many of the day-to-day technologies we take for granted incorporate telecommunications technologies.
Point-of-service or –sale (POS) • Point-of-service or point-of-sale (POS) systems automate the sales transaction data to a large extent. • The universal product code (UPC) is an example of a technology used by a POS. • POS and UPC work together to gather data. Telecommunications carries the data.
Virtual office • The office traditionally has meant a desk in an office building, downtown. • Today, due to telecommunications technology, the office may be your home, a small satellite office, or even your car.
Technology applications • The purpose of telecommunications is to provide business solutions. • Telecommunications, like any technology, has no inherent value.
Competitive advantage • Competitive advantage is that feature, any feature, of your organization that causes a customer to choose you over a competitor
Telecommunications utility • Telecommunications utility is the ability to leverage resources to remote locations
Channel • A channel is the communications path between a sender and receiver(s).
Basic communications model • Transport model is a simplistic mode of moving data from one source to one or more destinations through a medium.
Medium • A medium is the means of movement of signals from node to node. • A medium is any material that is used for propagation or transmission of signals.
Communications • Communications is a process that allows information to pass between a sender and one or more receivers. • Communications is a human process.
Telecommunications • Telecommunications is the transmission of data, or information, over a distance. • Telecommunications is the communication by electrical, electromagnetic, or photonic means, over a distance. • Telecommunications is a more general term and involves the transmission of information or ideas over a distance between humans or machines.
Data communications • Data communications is a specialized transmission of data between machines, using a code, and is generally not understandable to people in its transmitted form. • Data communications is different from telecommunications in that it is a specialized function.
Noise • Noise is any unwanted signal that interferes with the desired signal.
Encoding • Encoding is the process of placing the signal of interest onto or into a carrier signal. • Encoding signals onto or into a format for transmission is required in all cases.
Decoding • Decoding of signals is required so the true data can be removed from the envelope they were sent in.
Goal of telecommunications • The goal of telecommunication systems is the reliable movement of data over a distance.
A Telecommunications Model • The telecommunications process requires the inclusion of an encoder/decoder and transmitter/receiver.
Information and resource sharing • Information and resource sharing increase their value and reduce their cost.
Decentralization • The ability to decentralize and operate as if centrally located is paramount to any distributed organized.
Communications • Communications is a process that allows information to pass between a sender and one or more receivers ... the transfer of meaningful information or ideas from one location to a second location.
Objectives of telecommunications The objectives of telecommunications are: • Communicate • Distribute and share information • Allow organizations to operate with dispersed or distant functions as if they were centrally located • Share resources
Competitive advantage • Telecommunications in many organizations is the basis for competitive advantage. • Competitive advantage is anything that favorably distinguishes a firm, its products, or services from its competitors in the eyes of its customers or end-users in such a way that they customer chooses to purchase that product or service over another.
Stand-alone computer • Stand-alone, non-networked computers are self-contained and self-sufficient.
Connectivity • The value of computers is leveraged, and then enhanced, by networking them.
Network • A network is a group of nodes (computers) that can communicate among themselves because they are connected via channels.
Elements of a basic communications system • In a basic communications system there is always a sender, a message, a medium, and a receiver (in an environment of noise).
Value of technology • Technology does not exist for itself. The value of technology lies only in its ability to solve a business problem.
The players in the telecommunications environment • The players that affect telecommunications decisions are the results of laws imposed to level the playing field.
System • A system is a group of interrelated and interdependent parts working together to achieve a common goal. • Systems are composed of equipment, software, people, and procedures to achieve a stated goal.
Management Information Systems • Management Information Systems (MIS) are all systems and capabilities necessary to manage, process, transport, and use information as a resource in the organization.
Knowledge society • More people are now involved in knowledge and information related jobs than any other type.
Computer • A computer is a digital, internally stored program device that uses binary instruction and logic to store, retrieve, and manipulate numbers and textual data.
Centralized computing • Centralized computing is the environment where computing resources are in a central location and under central control. • Allowed several people to remotely access the computer from multiple locations.
Remote Job Entry • In a mainframe environment, individuals were connected by a remote job entry (RJE) terminal. • Jobs were submitted as batches into a queue and wait their turn for complete access to the computer.
Timeshare • Timeshare of computers is like the timeshare of condominiums: it allows multiple usage and lower cost. • Allows non-computer owners to enter jobs from a remote device, such as a terminal, and access the computational power of a service bureau’s computer.
Distributed computing • Distributed computing moved the power of the computer and its resident data close to the activities that required them. • Required telecommunications to move the data and applications among the processing sites.
