and saw many technological advances. One advancement is the widespread use of telephones in american homes and businesses. “By the 1950s, roughly two-thirds of American households had at least one telephone, with the percentage growing every year” (Fredman). Back then people only had one phone in the entire house, and they did not own it, it was rented from AT&T. The phones had a rotary dial on the front, since keypads had not been implemented yet.
TELEPHONE Telephone or fixed phone is communication device that can connect two users to make a conversation when they are in different places. Alexander Graham Bell is an inventor of the telephone, he found something that can help the other since he was 24 years old, before finally finding the telephone when he was 29 years old. Alexander Graham Bell get a patent on the electric telephone on March 7, 1876 by United States Patent and Trademark Office ( USPTO ). Telephone looks like a complicated machine, but actually telephone the simples device that exist in our homes. To be able to connect one user ( in telecommunication we called subscriber ) to another, this devices requires a network, commonly called a communication network.
Britain constructed lines to India in 1870, and lines to Australia in 1872 via submarine. The telegraph was also used to report news to the news companies for their newspapers. In the years 1902-1903 alone, there were over 92 million telegrams sent making that period of time the peak of the telegraph. One other time the telegraph was used was during World War I where people in offices and on the fronts of battle sent messages back and forth, some carrying bad news. If the telegraph was never created, Alexander Graham Bell would have never created the telephone in 1876 leading him to create The Telephone Company in 1878.
Communication in the Present: The telegraph was the first major milestone in the development of communication technology because it led to many of the things we use today and it’s similar to techniques we use today. Expansion in this past technology has made it possible for many of the things we use today, such as telephones, radio, cable television, Internet, and mobile phones. It was not long after the telegraph became a success before the next progression in technology came along, the telephone. The telephone was used to transmit speech electronically. Like the telegraph, the telephone was also a wire-based electrical system.
COMPANY PROFILE Motorola Inc. was founded on 25th September, 1928 in Schaumburg, Illinois, United States. It was an American multinational, founded by Galvin brothers, Paul and Joseph. It was initially named Galvin Manufacturing Corporation. After having lost $4.3 billion from 2007 to 2009, the company was divided into two independent public companies, Motorola Mobility and Motorola Solutions on January 4, 2011. The company's first products were battery-eliminators, devices that enabled battery-powered radios to operate on household electricity.
The first communication of fiber optic start off by Alexander Graham Bell in 1880 called as The Photophone. The Photophone is a device that permitted for the transmission of sound on a beam of light. Based on the Photophone capabilities which can use of an atmospheric transmission medium, Bell creates the first wireless telephone transmission within two buildings with 213 meters apart. However, the Photophone was more practical and took tangible shape. It does not show any practical prove until the enhancement has been made and secured the transport of light was permitted in the technologies of laser and optical fiber.
The photoelectric effect was also explained by Albert Einstein in 1905 for which he received the Nobel Prize in Physics in 1921. In 1946, Russell Ohl patented the modern junction semiconductor solar cell, which was discovered while working on the series of advances that would lead to the transistor. Chapin was the first to develop the highly efficient solar cell, Fuller and Pearson in 1954 using a diffused silicon p-n junction. In the last four decades, eccentric progress has been made, along with Megawatt solar power generating plants which are now been
There is a slogan of Telekom Malaysia is “Merintis Kemungkinan”. Telekom Malaysia has over 27000 employees and over 2.2 million broadband customers. Telekom Malaysia has been established as the Telecommunications Department in 1946, and it is privatized in 1987. Telekom Malaysia has separated its mobile telecommunications services from main business to focus more on Telekom Malaysia’s core fixed line telecommunications business. The first time of Telekom Malaysia to introduce the broad band services is in 2001, TM net is established as the largest Internet Service provider in the South-East Asia region and launching Blue Hyppo.com.
OSI (Open Systems Interconnection) model Brief of History Open Systems Interconnection (OSI). OSI model was introduced in the late 1970s which was proposed by British Standards Institute to the International Organization for Standardization (ISO) that to define communication infrastructure for distributed processing a standard architecture was needed. Most the design of OSI was done by a group at Honeywell Information Systems, headed by Mike Canepa, with Charlie Bachman as the principal technical member. Introduction OSI model served for the purpose to show there is a way to communicate different type of systems with different logic of underlying hardware and software through without the need to change the systems specifications. OSI model
After processing, output data can again be perceived as information. When information is packaged or used for understanding, it is known as knowledge. The importance of information, as early as in ancient times are already known. People used to transmit signal through the beacon towers. But as a science to study, the initial of information that researched was in 1746, Watson transfer electrical signals on the two mile wire.
