Communication Theory:
Инструкция: Communication theory focuses on studying the process of transmitting information from one point to another. It encompasses various concepts and models that help in understanding how communication occurs and how it influences individuals and society. The primary aim of communication theory is to analyze the factors that affect the effectiveness of communication, including the sender, the message, the medium, the receiver, and the context.

Output of the source:
Инструкция: The output of the source in communication theory symbolizes the message or information being transmitted. It represents the content that the sender wants to convey to the receiver. The source can be any form of communication, such as verbal, written, or non-verbal, and the output can be in the form of words, images, or gestures.

Definition of "Channel"
Инструкция: In communication theory, a channel refers to the medium through which the message is transmitted from the sender to the receiver. It can be a physical channel, such as air for sound or wires for electrical signals, or it can be a symbolic channel, such as language or gestures. The channel plays a crucial role in determining the clarity and accuracy of the message being conveyed.

Creation of Mathematical Theory for Communication Systems:
Инструкция: The mathematical theory for communication systems was created in the early 1940s by Claude Shannon, an American mathematician and electrical engineer. Shannon"s work on information theory laid the foundation for understanding the fundamental limits of communication and the principles of encoding, decoding, and error correction in communication systems.

Characteristics of Communication Theory:
Инструкция: Communication theory has several specific characteristics. Firstly, it emphasizes the importance of understanding the sender"s intentions and the recipient"s interpretation of the message. Secondly, it recognizes that communication is a dynamic process influenced by various external factors. Thirdly, it addresses the role of noise or interference in communication. Finally, it acknowledges the significance of feedback in assessing the success of communication.

Definition of Information Technology (IT):
Инструкция: Information technology (IT) refers to the use and management of computer-based systems for storing, retrieving, transmitting, and manipulating data. It encompasses various technologies, including hardware, software, networks, and databases, to facilitate the creation, storage, processing, and dissemination of information.

Main Concerns of IT:
Инструкция: The main concern of IT is to ensure the efficient and effective use of technology in organizations or institutions. It involves maintaining hardware and software systems, ensuring data security, managing networks, developing and implementing software solutions, and providing technical support to users.

Occupations of IT Professionals:
Инструкция: IT professionals work in various occupations that require expertise in managing and utilizing technology. They can work as software developers, network administrators, database administrators, system analysts, IT consultants, cybersecurity specialists, or technical support personnel. Their roles may vary depending on the specific area of IT they specialize in.

Definition of "Infotech":
Инструкция: "Infotech" is a term derived from the combination of "information" and "technology." It refers to the use of technology, particularly computer-based systems and information processing methods, to enhance the efficiency and effectiveness of information management and communication. Infotech encompasses various technologies, applications, and methods for storing, retrieving, processing, and disseminating information. It plays a vital role in facilitating decision-making processes, improving productivity, and enabling better communication and collaboration within organizations. Infotech is often used interchangeably with the broader term "IT" but may specifically focus on the application of technology in managing information.
