Description: A communication system is a set of components and protocols that enable the exchange of information between different entities, whether devices, systems, or people. These systems are fundamental in the digital age as they facilitate the efficient and effective transmission of data. A communication system can include hardware, such as routers and switches, as well as software that manages the transfer of information. The main characteristics of these systems include the ability to send and receive data, security in transmission, information integrity, and the ability to adapt to different formats and protocols. The relevance of communication systems lies in their crucial role in interconnecting devices in networks, automating processes, and enhancing collaboration in various environments. In the context of embedded systems, these communication systems are essential for interaction between microcontrollers and other devices, enabling the creation of smart and connected applications that respond to user and environmental needs.
History: Communication systems have evolved significantly since the invention of the telegraph in the 19th century, which allowed for the transmission of messages over long distances. Over time, technologies such as the telephone, radio, and television were developed, each improving the way people communicated. In the second half of the 20th century, the advent of computers and digitalization revolutionized communication systems, leading to computer networks and eventually the Internet. This advancement enabled the creation of standardized communication protocols, such as TCP/IP, which are the foundation of modern network communication.
Uses: Communication systems are used in a wide variety of applications, from data transmission in computer networks to communication in mobile devices. In the industrial sector, they are essential for automation and process control, allowing for monitoring and information exchange between machines. In healthcare, they facilitate communication between medical devices and data management systems. Additionally, they are fundamental in the development of emerging technologies such as the Internet of Things (IoT), where multiple devices communicate with each other to enhance efficiency and functionality.
Examples: An example of a communication system is the MQTT protocol, used in IoT applications for communication between devices. Another example is the use of local area networks (LAN) in offices, where routers and switches are used to connect computers and enable information exchange. In healthcare, communication systems are used in devices such as vital signs monitors that send data to patient management systems.
