Communication Technology

The modern  Communication Technology is mobile, computer, laptop, email, yahoo, television, radio, internet, etc. The world seems really small in front of this  Communication Technology.

Communication Technology is spread like a net in this whole world and bond us at one point. And now we all are connected and close where we are go and what we are doing.

History of  Communication Technology

The history was beginning when the world was creating and human was appearing. So let’s began from that story.

History began from smoke communication, use of smoke signals and drums in Africa, Asia, and the Americas. 1970 semaphore system was invented in Europe. The telecommunication system started in 1830.

In the 4th century BC, the Greek hydraulic semaphore system was used. In 1790 French engineer Claude chapped began his work in telegraphy, using the Paris of “clock” and this clock’s hand pointed in different symbols.

Swedish engineer Abraham edelcrantz made other systems from Stockholm to Drottningholm in 1794. Semaphore was suffering from the need for skilled operators. Finally, in 1880, the last commercial line was abandoned.

 Communication with electricity was unsuccessfully started in about 1726. the scientists Laplace, ampere Gauss were involved in this work. German physician has created the electrochemical telegraph.

In 1804 and 1809 Samuel Thomas von simmering, Spanish polymath and scientist Francisco Salva Campillo were working together for the development of electrical telegraphy.and they designed it with up to 35 multiple wires.

And finally, the first working Telegraph was invented in 1816 and worked by Francis Ronaldo used static electricity. In 1838 Charles Wheatstone and William Fothergill Cooke evident five meddle six-wire system which entered commercial.

Types of Communication Technology

Communication is the main thing that broadcast information to a vast audience. The world is all connected to a network of cables and satellites. Technology is classified into how fast we can communicate with others and connected every time.

Telephone/Mobile Phone

Nowadays the mobile phone is the Most common telecommunication system. Everyone knows about this device. In 1876 in March Alexander Graham Bell invented the telephone.first-time the telephone was landline communicate with other countries.

The first cell phone was invented in 1973 and Dr. Martin Cooper made the first call to his rival at Bell Labs. From then to now Mobile phone updates really fast. Small cheaps, developed protected screen, Long-lasting Battery, etc were invented successfully. Samsung, Sony, Huawei,iPhone Apple are the world wide company of cellphone.

Radio

Radio is not a much likely network now but once upon a time, this was the main system of telecommunication. In the 1900s and 1910s, early radio communication was used by the sea, vessels for communication with the other ships. After some years radio started with advertising but the producers realized that people could not enjoy the Radio unless they were not fascinating.

 Then Radio producer was decided to made Drama Programs. After that, the radio became popular day by day in late 1929 and early 1930. In September 2011 the FCC reported that there were 14865 radio stations only in the U.S.     

Television

In 1947 in US full-scale television first broadcasting. The inventor Lee Deforest tells that- while theoretically and technically television may be feasible, and financially it is an impossible”.in 2010 over 15 million Tvs with 99 percent of households reported owning at least one set in the USA. Now hundreds of tv channels are casting on tv and covering everything like- Sports, acting, entertainment, music, reality show, and even game events.

Firstly white and black tv invented, which was no Colour pack system and not even function. In this era, there are smart TVs with HD Colour system. Those TVs are also connected with the broadband system so one can easily browse anything.

Computer

The computer is the best invention of Communication technology. The first computer is used for calculations. Then the investor can realize that computer was more than a calculator. The calculator computer was invented in the 20th century. Then to now, the computer was updating with Its new software.there are many kinds of computers.

  • Analog computer
  • Digital Computer
  • Mainframe Computer
  • Supercomputer
  • Minicomputer
  • Microcomputer

Analog Computer

To counting the physical magnitude analog computer is using. In the 1960s after digital computer invention, the use of the analog computer is fully closed.

Digital Computer

In the 1930s and 1940s in the United States, Britain, and Germany the digital Computer began. Digital computer processing system made with binary digits orbit.

Mainframe Computer

International Business Machines Corporation(IBM), and other companies made large, expansive computers of increasing power In the 1950s and 1960s. Those are uses for Government research laboratories purpose in major corporations. Those computers are also called mainframe.

Supercomputer

A supercomputer is the most powerful computer all of them. It is very expensive also. It is using for weather forecasting, nuclear simulation, and government-sponsored research. Some technical systems of supercomputers are in common use In PCs today’s date.

Minicomputer

In the mid of the 1960s minicomputer was invented. It is small and inexpensive. Minicomputers were used in a single Department of an Organization or in a small group.

Microcomputer

The microcomputer is a small computer that is built with a microprocessor integrated circuit or chip. Our laptop is one kind of Microcomputer. In 1972 the Intel Corporation produced the first microprocessor.   

 Satellite

 Satellite is a device that places on spaceflight orbit for analyzing the space. The Soviet Union launched the first artificial satellite on 4 October 1957. Since then to now, 8900 satellites are launched from more than 40 countries.     

Internet

The Internet came about the 1990s as a result of the number of previous telecommunications projects such as ARPANET (Advanced Research Projects Agency Network) that were used primarily by the military. The previous idea was connecting with one computer into another in the milliary camp. To transfer the data from one computer to another is the basic idea of the internet. So in today’s date phones, laptops also have internet facilities. By using undersea cables the internet is used worldwide and 2.5 billion people using the internet. The best thing about the internet is, it does vast work but is wireless and any device can be connected with this. Email, Facebook, instant massaging, voice and video call or chat also the blessing of the internet.

The Advantage and Disadvantage of Communication Technology

Advantage

From this Communication technology, People can communicate from one corner to another corner in the world. So the study, doing business, or any kind of Jobs are doing easily by the Marcy of this technology.

  1. Businessmen can be connected easily with their customers even if they are in different countries. 
  2. Students can learn from foreign teachers with meet, google, and browsing their important thing also.    
  3. By satellite, we can know about the weather forecasting, up Coming cyclone, and analyze the orbits of the earth.
  4. We can chat, make calls, see our friends and family in video calls on one side to the other side in this world.
  5. The IT section is opening.so many jobless are getting a job.  

Disadvantage

  1.  Lack of relationship building with our family and friends.
  2. Children are addicted to mobile, laptop, tap.
  3. Obesity problems are increasing.
  4. Eay problems, heart problems are increasing.
  5. Radiation is increasing day by day in the air environment.     

Conclusion

After all of this, we can say that communication Technology is the best part of developing our technology but it has some problems also. But the blessing of communication technology we can do anything from a stay at home. We get more time for learning more about life and technology.
