True or false: Computer Communication Networks is a course offered in the Department of Health Informatics.
True
True or false: The grading breakdown for the course includes Time Attendance as a component.
True
True or false: The term 'communication' is defined as the act of receiving information.
False
True or false: In a direct link, a transmission path propagates signals directly from transmitter to receiver with no intermediate devices, except amplifiers to increase signal strength.
True
True or false: A configuration is point-to-point if it provides a direct link between two devices, and those are the only two devices sharing the medium.
True
True or false: Communication requires the presence of a medium to carry the information?
True
True or false: Coaxial cable is prone to interference?
False
True or false: Modulation is the conversion of the digital signal into an analogue signal, and demodulation converts the analogue signal back into a digital signal.
True
True or false: Microwaves can be used for data transmission through space?
True
True or false: Full-duplex transmission allows for simultaneous communication in both directions?
True
Match the following course assessments with their respective grading weights:
Attendance = 30% Assignments = 10% Presentations = 10% Quizzes = 10%

Match the following data encoding concepts with their definitions:
Modulation = Conversion of the digital signal into an analogue signal Demodulation = Conversion of the analogue signal back into a digital signal Encoding = Changing how data are represented Encryption = Encoding to hide the meaning of data
Match the following data transmission terms with their correct descriptions:
Direct Link = A transmission path that propagates signals directly from transmitter to receiver with no intermediate devices, except amplifiers to increase signal strength Point-to-Point = A configuration that provides a direct link between two devices, and those are the only two devices sharing the medium Multipoint = A configuration where more than two devices share the same medium Bandwidth = The range of frequencies within which all transmissions occur
Match the following data codes with their corresponding definitions:
ASCII = American Standards Committee for Information Interchange EBCDIC = Extended Binary Coded Decimal Interchange Code Analogue Data = Data that exists in continuous, non-discrete form Digital Data = Data that exists in discrete, discontinuous form
Match the following communication terms with their definitions:
Transmission medium = The physical path between the transmitter and receiver Transmission rate = The speed at which 'what is being communicated' is being sent Transmission efficiency = How much overhead must be added to manage the transmission Transmission code = An agreed 'language' to be used for communication
Match the following communication models with their descriptions:
Simplified Data Communications Model = Includes elements such as sender, receiver, addressing, protocol, and transmission medium Simplified Communication Model = Consists of basic elements like source, transmitter, transmission system, receiver, and destination Communication Model = Describes the process of communication and the properties required for effective communication Diagram of Simplified Communication Model = Illustrates the key tasks and elements involved in communication
Match the following types of transmission with their definitions:
