Clouds are formed from water droplets or snow crystals.
The mass of aqueous vapor that is suspended in the atmosphere is known as a cloud . Clouds, visible in the sky , are made up of water droplets or snow crystals. By dispersing visible light, they are usually perceived as white , although when they are very dense the light cannot pass through them and they appear gray or black .
For example: "The day dawned sunny, although the clouds didn't take long to appear" , "Look at those clouds: I think it will rain tomorrow" , "The sky was covered with clouds and it seemed to become night" .
Cloud types
According to their appearance and characteristics, clouds receive different nominations. Nimbus clouds are those capable of forming precipitation (which, depending on various factors, will be rain, snow or hail).
Stratus clouds , for their part, are stratified, while cumulus clouds have vertical development. Cirrus clouds , on the other hand, stand out for being formed by ice crystals.
Cloud computing makes it possible to use applications that run on a remote computer.
Other uses of the term
The notion of clouds, however, has other uses. A cloud, in a symbolic sense, can be a group or large amount of something that goes through the air : "After the explosion, a cloud of smoke covered the sky," "We were on the beach when a cloud of seagulls descended on the sea." » .
The large number of people or things that are together is also called a cloud: "Let's go somewhere else: this is a cloud of people," "I think my son dreams of living in a cloud of candy and sweets." This term can also be something that obscures or conceals something : "We are living in difficult times, but the clouds have already moved away."
Cloud computing
The English term cloud computing refers to working in the cloud and means operating applications that are located and executed on a remote computer , and that store their session data there. Currently this technology is increasingly popular, both in the field of video games and in the development of applications and the creation of documents.
In theory, any application can run in the cloud, regardless of the volume of information that must be transmitted per second, although it goes without saying that in certain cases it only becomes practicable if the user has a high- speed Internet connection with low latency. extremely low (that is, the delay in communication is almost imperceptible to humans).
Advantages and disadvantages
Let's look at some of the advantages of working in the cloud:
* allows a device with basic or moderate specifications to "run" extremely demanding applications, since the processing is done on a remote server ;
* does not require disk space from the user to store their applications;
* By always remaining on the computers of the company that provides the cloud services, the same individual can use their programs and personal documents wherever they are, with any device;
* It offers an almost universal level of compatibility, since it does not usually require more functions than an Internet connection to allow interaction with a multitude of applications.
On the other hand, the cloud has its disadvantages, such as:
* A cut in the Internet service is enough for a large number of users to be left without access to their programs and games, despite having paid for them and still having electricity supply;
* similar to the previous point, you cannot have true control over our applications and our information , since they are located in a remote site and are maintained by third parties;
* There are more risks of security issues, especially when sensitive data is stored in the cloud.
