Data Transmission Modes

What is serial transmission?

• Sending data one bit at a time over a communication channel.

• Transmitting data wirelessly

• Receiving data in parallel

• Sending data all at once

What is parallel transmission?

• Sending multiple bits simultaneously over separate channels within the same cable or connection.

• Sending data sequentially over multiple channels within the same cable

• Sending bits simultaneously over the same channel within a cable

• Transmitting data over a single channel within a cable

Explain simplex mode of data transmission.

• Data transmission in simplex mode is slower than other modes

• Data flows bidirectionally between sender and receiver

• Simplex mode allows simultaneous data transmission in both directions

• In simplex mode of data transmission, data flows in only one direction, from the sender to the receiver.

What is half duplex mode of data transmission?

• Half duplex mode enables data transmission in multiple directions simultaneously.

• Half duplex mode of data transmission allows data to flow in both directions, but not simultaneously.

• Half duplex mode restricts data transmission to a single device.

• Half duplex mode allows data to flow in one direction only.

Describe full duplex mode of data transmission.

• Full duplex mode requires data to be sent and received sequentially

• Full duplex mode of data transmission allows for simultaneous two-way communication where data can be sent and received at the same time.

• Full duplex mode is limited to sending data only

• Full duplex mode allows for one-way communication only

What are the advantages of serial transmission?

• Lower cost

• Higher data security

• Simpler hardware implementation, longer transmission distances, better noise immunity, and easier synchronization between sender and receiver.

• Faster data transfer speed

What are the disadvantages of serial transmission?

• Slower data transfer rates, susceptibility to noise and interference, difficulty in implementing bidirectional communication

• Ease of implementing bidirectional communication

• Immunity to noise and interference

• Faster data transfer rates

What are the advantages of parallel transmission?

• Faster data transfer rates, improved error detection and correction, suitable for short-distance communication

• Slower data transfer rates, decreased error detection and correction, suitable for long-distance communication

• Incompatible with modern devices, prone to overheating, difficult to implement

• Limited bandwidth, higher cost, increased susceptibility to interference

What are the disadvantages of parallel transmission?

• Lower cost, decreased complexity, immunity to crosstalk and interference

• Limited bandwidth, inefficient data transfer, prone to synchronization issues

• Higher cost, increased complexity, susceptibility to crosstalk and interference

• Slower speed, reduced efficiency, vulnerability to signal loss

Explain the differences between half duplex and full duplex modes of data transmission.

• Half duplex allows communication in both directions but not simultaneously

• Full duplex allows communication in both directions simultaneously

• Half duplex is faster than full duplex

• Full duplex is more reliable than half duplex
