Abstract
AT&T has its roots from the Bell System Company formed in the 19th century. Following the invention of the telephone by Alexander Graham Bell, AT&T became part of the system of the company. Its integration to a telecommunications services and equipment company took place between the years 1984 to 1996 following an agreement reached by the company and the U.S Justice Department. From then on, it became a leader in global networking. ATT became the 14th largest company in the world while considering its market value. Its influence in the world is big as it boasts a total of over a hundred million customers stretching over the globe.
Transistor
A transistor is a semiconductor with three terminals used to connect to an external circuit. It is an amplifier that switches electric signals and electronic power. Three key physicists William B. Shockley, John Bardeen and Walter H. Brattain invented the transistor. This invention took place in New Jersey at Bell Labs’. Engineers later developed the transistor at Western Electric plants in Pennsylvania. Much of the developmental work involved was the diffusion of chemical agents known as dopants into semiconductors. Other developmental works included the purification of silicon and crystal growing. This took more than a decade to be completed so that the transistor could become fully developed.
The transistor has had a massive effect on the society today. Its invention has been the core to the development of other technological advancements. Practically all modern day equipments use transistors. Manufacture of radios and televisions requires the installment of a transistor. Computers are now re-designed to use transistors. This has reduced their size and lowered the heating problem caused by processor. Other devices commonly used in society such as calculators also use the transistor. Many electronic devices have the LED light. The transistor turns on this LED light. Without the transistor, it is impossible for modern day electronics to function effectively.
Fiber optics
An optic fiber is a strand of glass that is long and thin. It transmits light over long distances at very high speeds. This has made it effective in the field of communication as data sent over long distances at high speeds makes communication effective, fast and reliable.
Telecommunication companies in societies today use the fiber optic in the transmission of data, voice and video over long distances. Multinational companies use fiber optics in the transfer of their financial information from one computer to another securely. The optic fiber has facilitated high-speed internet connectivity across the globe in an effort to speed up communication and the transfer of data. This has brought about the growth of the economy in many countries across the globe. Business people transact their business transactions at a faster rate than before.
Hiring engineers
In the hay day of AT&T, Bell Telephone Laboratories would look for engineers adequately qualified for the engineering jobs. They would look for engineers who were innovating with the determination and the desire to develop and invent new devices. These devices would push the telecommunication and industrial to new heights. Bell Telephone Laboratories hired engineers expected to be disciplined with a keen interest of following orders. Engineers hired by Bell Telephone Laboratories would be expected to work well under pressure and be able to complete a project within the set deadline.
