 Web Site A web site is a collection of web pages which are digital files generally written using Hyper Text Markup Language (HTML). For a web site to be available to everyone in the world at all times, it must be stored or "hosted" on a computer that is connected to the internet round the clock. Such a computer is known as a Web server. The web pages of a website are linked together (through hyperlinks and hypertext) and share a common interface and design. The site might also contain additional documents and files such as images, videos or other digital assets.  With Internet invading in every sphere, we see websites for all kind of causes and purposes. So, we can also say that a website can also be thought of as a digital environment capable of delivering information and solutions and promoting interaction between people, places, and things to support the goals of the organization it was created for.  Components of a Website As you know that a web

This works as well as you are the only person who will be using them. But you must have noticed that much of the time though, they probably aren't being used and and just lie idle. But at places where many computers are used such as your school or offices or banks etc, it would cost a lot of money for every computer to have its own printer . And for every computer to have its own printer . And for the majority of the time, like your printer at home, it wouldn't be used.                                                                                      But the joining computers together to form a network, they are able to share one printer. This means that more money can be spent buying a better quality printer and that the printer is being used much more of the t

 ACCOMMODATION OF AN EYE        A normal eye can see the near and far off objects clearly if the sharp images of these objects are formed on the retina. Since the distance between the eye lens and retina is fixed, so to see the objects at different positions from the lens, the focal length of the lens has to be changed accordingly to form the sharp images of these objects.                                                        If the objects to be seen is far off, then the sharp image of this object can be formed on the retina of the eye by increasing the focal length of the eye lens. The focal length of a lens increases if its thickness decreases. Thus, to decrease the thickness of the eye lens and hence to increase its focal length, ciliary muscles are completely relaxed. Now the parallel beam of light coming from the far off objects is focussed on the retina and hence the object is seen clearly.                                             If the object to be seen in cl

  The Human Eye       The human eye is the most important organ of human body. It is used to see the beautiful nature and the natural phenomena. The human eye is shown in figure                                               1. Cornea. Cornea is the outermost part of the eye. It is transparent part of eye and allows the light to enter in the eye. 2. Iris. It is circular dark diaphragm having a hole in its center. This hole is called pupil. The circular dark diaphragm has muscles and color pigments. The color of an eye depends upon the color of these pigments. The function of iris is to control the size of the pupil. On the other hand, pupil controls and regulates the light entering the eye. The pupil becomes small when bright light falls on the eye. However, it becomes wide when there is dim light.  3. Lens. The eye lens is a crystalline double convex lens and made of transparent and flexible tissue. It is behind the pupil and held by the muscles called ciliary muscles

Transportation is the movement of materials from one part to another, usually from the region of their availability to the region of their use, storage or elimination. Transportation occurs in all organisms, from microscopic ones to large size trees and animals. Transportation in Human Beings It is carried out by circulatory system. In human beings, the circulatory system is made of tubes, a pumping heart and circulating fluids, blood and lymph. Depending upon the fluid, the circulatory system is of two types, blood vascular system and lymphatic system. Blood  It is a mobile fluid connective tissue of reddish color that circulates in the human body, supplying nutrients and oxygen to all the living cells and taking away waste products as well as carbon dioxide from them. The blood carrying oxygen attached to haemoglobin (as oxyhaemoglobin) is called oxygenated blood. The blood carrying carbon dioxide and little oxygen is called deoxygenated blood. An adult human has a total
