(2).There are three data transmission modes. Explain two of them of your choice using a
diagram.
Answers
Answer:
The simplest way to explain the difference between the two is that absolute pressure uses absolute zero as its zero point, while gauge pressure uses atmospheric pressure as its zero point. Due to varying atmospheric pressure, gauge pressure measurement is not precise, while absolute pressure is always definite.
Simplex mode, Half duplex mode, and Full duplex mode
Explanation:
Half-duplex gadgets can handiest transmit in a single path at one time.
With half-duplex mode, statistics can flow in directions, however now no longer at the identical time.
The time period duplex, on its own, refers back to the functionality to ship and acquire statistics.
Duplex is regularly used whilst speaking me approximately conversations over a cellphone or computer.
The time period full-duplex describes simultaneous statistics transmission and receptions over one channel. A full-duplex tool is able to bi-directional community statistics transmissions at an identical time.
