Answer to Question 1

The term elastic means that the amount of resources leased can be increased or decreased dynamically, programmatically, in a short span of time and that organizations pay for just the resources that they use. The resources are pooled, because many different organizations use the same physical hardware; they share that hardware through virtualization. Cloud vendors dynamically allocate virtual machines to physical hardware as customer needs increase or decrease.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
