The definition of a cloud is a visible mass of small water droplets or ice particles which are suspended in the sky.
Facts About Clouds
When a cloud forms in space, it is known as an interstellar cloud, or a nebula. Three components are necessary for clouds to form: water vapor, cool or cold air, and condensation nuclei. A white cloud means that the cloud was formed with warm air. A grey, or a black cloud, means that the cloud contains larger drops of water.
There are four main types of clouds:
- Cumulus - the white and puffy clouds in the sky, generally under 7,000 feet in altitude. Made up almost entirely of water drops.
- Stratus - the flatter clouds that stretch over greater lengths of distance in the sky, generally under 7,000 feet in altitude. Made up almost entirely of water drops.
- Cirrus - clouds which are extremely high in the sky, generally over 18,000 feet, and are very thin and feathery looking. Composed primarily of ice crystals.
- Cumulonimbus - clouds which go the highest of all clouds, up to 60,000 feet. They produce storms, thunder and lightening.
An example of a cloud is what makes the sky dark on a rainy day.

cloud - Computer Definition
A wide area network (WAN) commonly is depicted as a cloud, which serves to obscure its complex inner workings from view. Data just pops in on one side of the cloud and pops out on the other side, so to speak.
A communications network. The word "cloud" often refers to the Internet. However, the term "cloud computing" refers to the services that have enabled the cloud to become so prominent in everyday life (see cloud computing). See private cloud and personal cloud. A Cloud May Refer to Any Network A cloud can be a wide area network (WAN) like the Internet or a local area network (LAN) within an organization. For decades, network diagrams have used a cloud-like symbol to reduce the entire infrastructure into simple entry and exit points. Cloud symbols are drawn when the network architecture is not material to the illustration. Inside the cloud, there may be any number of cables, routers, switches and servers that handle the forwarding of data from one point to another, as well as the required data processing.
