To test data integrity, the sender of the data calculates checksum value by taking the sum of the binary data transmitted. When receiving the data, the receiver can perform the same calculation on the data and compare it with the checksum value provided by the sender.
Venusâ atmosphere is much thicker than Earthâs, preventing a clear view of the planet. Its atmosphere is dominated by carbon dioxide, and features swirling clouds of sulfuric acid. The atmosphere on Mars is also dominated by carbon dioxide, although unlike Venus, it is quite thin. Gas giants are composed of gases.
The atmosphere of Venus is very thick and is about 90 times more massive than Earth's atmosphere. It is mostly carbon dioxide gas (about 96%), with some nitrogen (about 3%) and a very small amount of water vapor (0.003%). Venus also has a thick layer of sulfuric acid clouds. The sulfur in the clouds gives Venus its yellowish appearance. The clouds in Venus's atmosphere also move very fast, reaching speeds of 220 miles per hour (350 km per hour).
