The main difference between power and control cables is that control cables are plain annealed conductors whereas the power cables are conductors of copper and aluminum. Where power cables are made for transmitting electricity, the control cables act as controlling agents in the different process automation fields.

2-Wire vs. 4-Wire: A 4-wire transmitter is either powered by a 110V or 220V power supply. This allows direct activation of relays, pumps, solenoids, etc. ... A 2-wire transmitter is loop-powered, which means it is powered by a low voltage, low current, DC power supply, typically 24V.

Communication is simply the flow of information from the first party (the sender) to the second party (the receiver) irrespective of whether the recipient has properly downloaded the message or not, whereas effective communication is the flow of information in exactly the same manner the sender intends to do so.

Flow Control basically means that TCP will ensure that a sender is not overwhelming a receiver by sending packets faster than it can consume. ... Congestion control is about preventing a node from overwhelming the network (i.e. the links between two nodes), while Flow Control is about the end-node.

Analog communication is entirely the use of continuous time varying signal for the transmission of information from the sender to receiver. On the other hand, digital communication utilizes the usage of digital technology for sending the information over the channel.

Parallel connections have multiple wires running parallel to each other (hence the name), and can transmit data on all the wires simultaneously. Serial, on the other hand, uses a single wire to transfer the data bits one at a time.

TYPES OF DATA FLOW IN COMMUNICATION SYSTEM. Communication between two devices can be simplex, half-duplex, or full-duplex. SIMPLEX: In simplex mode, the communication is unidirectional, as on a one-way street.

Data is what we need to sent whereas signal is what we can sent. Data is being carried whereas signal is the carriers. Data can not transmit signal whereas signal can transmit data.

The difference between events and messages is that events are used for intra-stack communication, whereas messages are used for inter-stack communication.
