The history of telecommunications began in the late 18th century with the French engineer Claude Chappe's optical telegraph system, which used towers and line of sight to transmit information faster than previous methods. Wireless communication transmits electromagnetic waves through space without cables, providing mobility. Bluetooth is an example of this, using wireless personal area networks to connect commonly carried devices like phones, headphones, and computers.

Telecommunications
Telecommunications began in the late 18th century with the development of optical telegraph systems using towers and line of sight signaling. In 1792, the French engineer Claude Chappe built the first optical telegraph system, allowing faster transmission of information over long distances without traveling. Wireless communication transmits electromagnetic waves through space rather than physical cables, providing advantages like Bluetooth which connects devices over short ranges without wires as an example of wireless personal area networks.

Information and communication technology
ICT began when humans started communicating and sharing information with each other. It involves using technology to gather and share data through hardware, software, and networks. The history of ICT can be broken into four periods: premechanical (3000 BC to 1450), mechanical (1450 to 1840), electromechanical (1840 to 1940), and electronic (1940 to present). Key developments included the invention of the telegraph, telephone, transistor, integrated circuit, and personal computers. Today, ICT fuses hardware, software, and communication networks and is exemplified by the World Wide Web, online systems, functions, and platforms.

Activity 10 timeline history of internet
The first concepts of a globally interconnected network of computers were developed by J.C.R. Licklider in the 1960s, who envisioned a network through which users could access data and programs from any site. Research in the 1960s by Kleinrock and others demonstrated the theoretical feasibility of packet switching, laying the foundations for computer networking. The Advanced Research Projects Agency Network (ARPANET) was developed in the late 1960s and early 1970s based on these ideas, with the first message sent between computers in 1969. The ARPANET was then used to demonstrate networking concepts publicly for the first time in 1972.

powerpoint presentation of LiFi
This document discusses Li-Fi technology. It provides background on Li-Fi, noting that it uses LED lights to transmit data through light instead of radio waves like Wi-Fi. The document outlines some of the history of Li-Fi development and explains the basic concept of how data is encoded in the light. It then discusses potential applications of Li-Fi including in traffic lights, planes, underwater, and intrinsically safe environments. Advantages are highlighted such as high data rates, security, energy efficiency, and ability to work in places where Wi-Fi cannot. The conclusion is that Li-Fi could provide an alternative to Wi-Fi hotspots using existing light bulbs.
Presentation final
Ibrahim Quddusi's presentation discusses the emerging technology of Li-Fi, which stands for Light Fidelity. Li-Fi transmits data through illumination by varying the intensity of LED light bulbs faster than the human eye can detect. A German physicist first began developing this concept in 2004. Li-Fi offers several advantages over traditional Wi-Fi such as higher speeds, more available spectrum, and better security since light cannot pass through walls. While still in development, Li-Fi may one day allow data transmission through light bulbs in homes and public areas like traffic lights.

The document discusses the contributions of the telegraph to the development of international mass communication. It notes that the telegraph allowed for fast transmission of information across long distances, laying the foundation for near-instantaneous global communication. This relatively fast speed helped information to be more easily sent and received internationally. Additionally, the widespread interest and use of the telegraph led to the establishment of standards organizations like the International Telegraph Union, now called the International Telecommunication Union, to facilitate international cooperation on telecommunication issues. Thus, the telegraph significantly advanced international mass communication by enabling faster transmission of information worldwide and establishing standards bodies to support continued development of cross-border communication networks and services.

Infor telecommunications
- 2. When the history of telecommunications began? • It began at the end of the XVIII century
- 3. First wit Telecommunications. How important was it ? • In 1792 a project of the French engineer Claude Chappe was aproved to build the first system of optical telegraphy. This system required the construction of towers for specific use. • The importance that the telegraph had, was that the transmission of information was much faster and you could get all kinds of information and details you could communicate with people who were far without moving.
- 4. What is wireless communication? • Wireless communication is one in which sender and receiver are connected by a physical means of propagation, but using electromagnetic waves through space.They are an advantage because they don t need cables
- 5. → BLUETOOTH • Bluetooth is a wireless comunnication example. It belongs to the Wireless Personal Area Networks, which basically means that serves to connect the devices we carry on.
