: (A, An, The)Telecommunications refers to (a, an, the) the electronic transmission of signals for communications, including such means as telephone, radio, and television.
Telecommunications has ___ potential to create profound changes in business because it lessens ___ barriers of time and distance. Telecommunications not only is changing ___ way businesses operate but also is altering ___ nature of commerce itself. As networks are connected with one another and information is transmitted more freely, ___ competitive marketplace is making excellent quality and service imperative for success. Data communications, ___ specialized subset of telecommunications, refers to ___ electronic collection, processings and distribution of datatypically between computer system hardware devices. Data communications is accomplished through ___ use of telecommunications technology. ___ figure 6. shows ___ general model of telecommunications. ___ model starts with ___ sending unit, such as ___ person, ___ computer system, ___ terminal, or another device, that originates ___ message. ___ sending unit transmits ___ signal to ___ telecommunications device.___ telecommunications device performs ___ number of functions, which can include converting ___ signal into ___ different form or from one type to another. ___ telecommunications device is ___ hardware component that allows electronic communication to occur or to occur more efficiently. ___ telecommunications device then sends ___ signal through ___ medium. ___ telecommunications medium is anything that carries ___ electronic signal and interfaces between ___ sending device and ___ receiving device. ___ signal is received by another telecommunications device that is connected to ___ receiving computer. ___ process can then be reversed and another message can go back from ___ receiving unit to ___ original sending unit. ___ important characteristic of telecommunications is ___ speed at which information is transmitted, measured in bits per second (bps). Common speeds are in ___ range of thousands of bits per second (Kbps) to millions of bits per second (Mbps).

1. For example, ___ car with gradually loosening bolts (which is difficult to prevent in a corrosive and thermal and mechanical cyclic loading environment) is ___ poor product because of safety, vibration, and noise problems. 2. In these cases, ___ choice should be made of ___ single member at the joint on which to assume the external force to be acting. 3. ___ medium through which a photon can only travel a short distance without being absorbed is known as optically thick. 4. Laboratory users often use ___ ice bath made from a good-quality Dewar flask or vacuum-insulated bottle of at least 1 pt capacity, as shown in ___ Figure 4. 5. It must be emphasized that ___ proper knowledge of these properties is vital to the prediction of fluid mechanics and heat transfer phenomena in rheological fluids. 6. This arrangement results in ___ high quality at the exit from the low-pressure steam turbine. 7. The spill-return nozzle is a simplex nozzle with ___ rear passage that returns fuel to the injection pump. 8. ___sweeping and ___ renewal of the droplet growth process is responsible for the high heat transfer coefficients associated with dropwise condensation. 9. The thermocouple effect between ___ junction of two dissimilar metals causes an electric current that may induce electrolytic corrosion. 10. Products are sometimes specially mounted to counter ___ destructive effects of shock and vibration. 11. If ___ mechanical stresses so produced are below ___acceptable safe working stress of ___ materials involved, no direct protection methods are required.
