Cloud

The color of a cloud tells much about what is going on in the interior of the cloud. Clouds form when relatively warm air containing water vapor is lighter than its nearby air and this causes it to rise. As it rises it cools and the vapor condenses out of the air as micro-droplets. These minute particles of water are fairly densely packed, and sunlight cannot go through far into the cloud before it is reflected out, giving a cloud its attribute white color. As a cloud matures, the droplets may join to produce larger droplets, which may themselves merge to form droplets large enough to fall as rain. In this process of accretion, the space between droplets becomes larger and larger, permitting light to enter much farther into the cloud.

If the cloud is satisfactorily large, and the droplets within are spaced far enough apart, it may be that a percentage of the light which enters the cloud is not reflected back out before it is absorbed .This process of reflection/absorption is what leads to the range of cloud color from white through grey through black. For the same reason, the undersides of large clouds and heavy overcasts appear various degrees of grey; little light is being reflected or transmitted back to the observer.

Entertainment

Entertainment is an occasion, piece, or movement designed to give enjoyment or leisure to an audience. The audience may join in the entertainment passively as in actively as in computer games. The playing of sports and reading of journalism are usually included in entertainment, but these are regularly called activity more specifically, because they involve some energetic participation past mere leisure. While people have laughing themselves since the beginning of time, the entertainment industry first became a leading force in culture in the 20th century with the development of latest electronic technologies of recording and spreading.

Western peoples, tired of serious purposes and gathering massacre, turned to popular culture following the two world wars. The financial basis of this new culture was advertising of free or inexpensive entertainment program. In their peak, television networks were great selling machines which, besides entertaining people, prohibited both commercial and political markets by providing direct access to the group of customers. This "territory" is now in danger by the explosion and segmentation of media and especially by the growing importance of communication by computer which allows the consumer to look for out the informational message as an alternative of having it broadcast to him or her. A new system of world history sees Americans in changeover between a fourth, entertainment-based "society" and a future fifth evolution based on computer communication.

Computer

A computer is a machine for manipulating data according to a list of instructions. Computers take plentiful physical forms. Early electronic computers were the size of a large room, overriding as much power as several hundred modern personal computers. Today, computers can be made small enough to fit into a wrist watch and be powered from a watch battery. Society has come to distinguish personal computers and their portable equivalent, the laptop computer, as icons of the information age; they are what most people think of as a computer. However, the most general form of computer in use today is by far the embedded computer. Embedded computers are small, simple devices that are often used to organize other devices—for example; they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and even children's toys.
The ability to store and implement programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turing thesis is a mathematical statement of this flexibility: Any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks as long as time and storage capability are not considerations.

Bond

In finance, a bond is a debt security, in which the authorized issuer owes the holders a debt and is grateful to repay the principal and interest at a later date, termed maturity. Other conditions may also be attached to the bond issue, such as the obligation for the issuer to provide certain information to the bond holder, or limitations on the behavior of the issuer. Bonds are generally issued for a permanent term longer than ten years. U.S Treasury securities issue debt with life of ten years. New debt between one year and ten years is a note, and new debit less than a year is a bill.
A bond is simply a loan, but in the form of a security, although expressions used is rather different. The issuer is equivalent to the borrower, the bond holder to the lender, and the voucher to the interest. Bonds enable the issuer to finance long-term investments with external funds. Certificates of deposit (CDs) or commercial paper are measured money market instruments
