Understanding Communication Systems

What is the definition of a communication system?

• A communication system is a set of components that enables the transmission of information from a sender to a receiver.

• A communication system is a device used for measuring temperature.

• A communication system is a method for storing data securely.

• A communication system is a type of software for editing images.

List the main components of a communication system.

• Transmitter, Channel, Receiver, Noise

• Encoder, Buffer, Source, Destination

• Router, Protocol, Data, Interface

• Modulator, Decoder, Feedback, Signal

What are the elements involved in data transmission?

• Network Switch, Router, Firewall, Server

• User Interface, Database, API, Cache

• Sender, Receiver, Transmission Medium, Message, Protocol

• Data Storage, Encryption, Backup, Firewall

Define simplex communication mode.

• Simplex communication mode requires a two-way communication channel.

• Simplex communication mode allows data transmission in both directions.

• Simplex communication mode is used for broadcasting signals to multiple receivers.

• Simplex communication mode allows data transmission in one direction only.

Explain half duplex communication mode with an example.

• A telephone call between two people.

• An example of half duplex communication is a walkie-talkie.

• A one-way radio broadcast.

• A video conference with multiple participants.

What is full duplex communication mode?

• Full duplex communication mode enables simultaneous two-way communication.

• Full duplex communication mode is limited to audio signals only.

• Full duplex communication requires a single channel for data transfer.

• Half duplex communication allows one-way communication only.

Differentiate between LAN and WAN.

• LAN connections are slower than WAN connections.

• LAN is for local connections; WAN is for long-distance connections.

• LAN is for global connections; WAN is for local connections.

• LAN is a type of WAN; WAN is a type of LAN.

What does PAN stand for and how does it differ from LAN?

• PAN stands for Public Area Network.

• PAN is a Local Area Network variant.

• PAN stands for Personal Area Network.

• PAN is a type of Wide Area Network.

Describe the characteristics of a CAN.

• A CAN is a multi-master, message-oriented protocol that allows devices to communicate in a reliable and efficient manner, featuring error detection and prioritization.

• A CAN is a protocol that does not support error detection and prioritization, making communication unreliable.

• A CAN is a protocol used exclusively for video streaming and does not apply to device communication.

• A CAN is a single-master, data-oriented protocol that only allows one device to communicate at a time.

What are the advantages of using a LAN?

• Advantages of using a LAN include high-speed data transfer, resource sharing, improved communication, enhanced security, and cost-effectiveness.

• Increased vulnerability to attacks

• Limited resource sharing

• Slow data transfer speeds
