Transmission efficiency

Which one of the following transmission media is immune to electrical interference?

Optical fibre

Which one of the following is NOT a property required for communication between two entities?

Conversion of brain waves into speech

Which one of the following is NOT a type of transmission mode?

Multiplex

Which type of transmission media provides a direct link between two devices and does not allow any other devices to share the medium?

Point-to-point configuration

What is the purpose of encoding data?

To change how data are represented

What is the device used to convert a digital signal into an analogue signal?

Modem

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 books with their authors:

Computer Networks: A Systems Approach = Larry L. Peterson, Bruce S. Davie Computer Networks = Andrew S. Tanenbaum, David J. Wetherall Computer Networking A Top-Down Approach = James F. Kurose, Keith W. Ross Simple Steps to Data Encryption, A Practical Guide to Secure Computing = Peter Loshin

Match the following course topics with their descriptions:

OSI model = A conceptual framework used to understand and describe network protocols TCP/IP = A set of protocols used for communication over the internet Wireless Communications = The transfer of information between two or more points that are not connected by an electrical conductor Cybersecurity = The practice of protecting systems, networks, and programs from digital attacks

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:

Simplex = Transmission in one direction only Half-duplex = Transmission in both directions, but only in one direction at any time Full-duplex = Transmission in both directions simultaneously, if required Guided = Transmission where the medium is bounded and the transmission is contained within it

Match the following types of transmission media with their descriptions:

Two wire = Simplest arrangement, with two wires, separated by air. Only reliable for low data rates Twisted Pair = Two insulated wires twisted together. Suitable for short distance medium speed links Coaxial cable = Single central wire, separated from woven outer conductor by plastic insulation. Can support medium to high data rates Optical Fibre = Uses single strand of glass as core, with light shield around it. Capable of high data rates
