Telecommunication Essay

Throughout history welding has been known as, and referred to as nay things. It has been relayed to and called such things as, blacksmith or iron workers because of its way of using and manipulating metal. Welding can be dated back to over 2000 years during ancient times like the Bronze Age, but it was first documented as metal shaping in Egypt in 4000 B.C. Some civilizations started with less magnetic materials like copper, then progressed to more iron based materials like bronze, gold, iron and silver. In 3000 B.C. using pressure welding The Sumerians beat and formed swords for battle. Later into the 19th century Sir Humphrey Davy was the inventor of the electric arc, that was powered by battery and using two electrodes. Between 1808 - 1827

2. Obtained a 2-3 cm strip of magnesium metal ribbon and coiled it loosely into a small ball. Added the magnesium metal to the acid in the test tube.

Moving beyond the modern day technology that aides the common citizens, there is also an abundant amount of technology that aides in police work such as facial recognition, iris scans and mobile data terminals. Many people don’t understand how simple, yet beneficial facial recognition is in the police work. When first hearing facial recognition many minds may jump to some complex idea but the process is quite easy in fact even simple social networking

People were so full of curiosity on how the light bulb worked. It led to everybody wanted electricity in their homes, and it began to evolve over time to what we have in this time.

The first step that needed to be done in this experiment was adding hydrochloric acid (HCl)

Improvements in communication and transportation became apparent in the nineteenth century due to the expansion of the textile, mining and metallurgy industries. By the middle of the nineteenth century, communication was transformed by the invention of the electronic telegraph and the transatlantic cable, which “Established instant communication between the old and new worlds.” (p. 413) Transportation was also transformed by canal and road building, as well as the introduction of locomotives and steamboats.

4) The first was the interconnected transportation and communication networks for example telegraph, railroad and steamship.

| NaHCO₃ reacts with the hydrochloric acid by heating up violently, bubbling, dissolves, and new gas formation

Procedure: Filled each test tube with substances provided and subjected them to various conditions. These conditions included, heat, cold water, hot water, acid and basic additions and tested on litmus paper. The reactions were observed and documented at each step.

To see if the concentration of hydrochloric acid will increase the rate of the reaction between magnesium ribbon and hydrochloric acid.

4. A small portion of one of the known salts was placed onto a clean spatula. 5. The portion was transferred to a pre-soaked wooden splint. 6.

There is a wide range of communications technology that is used by the Public Services. Every Public Service uses some form of technological equipment as it is vital to carry out their duties effectively and efficiently. Depending on what job they are required to do, they will use different types of technological equipment. Communications technology being, The Police National Computer, Roaming network, Radios, Cormorant digital voice, Local Area Network and Satellite communications.

We began this experiment by obtaining and measuring the mass of a 20 x 150 mm test tube and a 22 x 175 mm test tube with boiling stones. We then weighed out 2 grams of zinc and iodine. First, we added the zinc to the 20 x 150 mm and weighed it out. Then we added the iodine to the 20 x 150 mm and weighed it out. This gave us the amount of each element we were working with before the reaction. Next, we made weak acidified water by adding 18 drops of acetic acid to 25 mL of distilled water in a 50 mL beaker. Then we added 5 mL of acidic solution to the 20 x 150 mm test tube. After the solution is added we swirled the test tube until the liquid became colorless. Once colorless, we poured it into the 22 x 175 mm test tube. We repeated mixing the acid with the zinc and iodine two more times. Then we repeated it 3 more times but poured the solution down the drain. Furthermore, we used a bunsen burner to softly dry off the zinc in the 20 x 150 mm test tube. Once, completely dry we let the test tube

Directions: Select a topic from the case studies in the text. You may choose any of the topics, except those covered in previous assignments. Examples of topics you might investigate include: using telecommunications to keep in touch with co-workers; telecommunications innovation; managing telecommunications; emerging telecommunications technologies; and so on.

British Telecom My aim in this investigation is to discuss whether or not British Telecom has successfully grown and developed since its Privatisation to compete on a world scale. In addition to this has it any long-term strategies for future growth and development of products. According to the 1996 Budget Red Book, more than 50 major businesses have been privatised since 1979 and the state owned sector of industry has been reduced be two-thirds.
