The purpose of output hardware is to provide the user with the means to view information produced by the computer system. Information is output in either hardcopy or softcopy form. Hardcopy output can be held in your hand, such as paper with text (words or numbers) or graphics printed on it. Softcopy output is displayed on a monitor.
Monitor is a component with a display screen for viewing computer data, television programs, etc.
Printer is a computer output device that produces a paper copy of data or graphics.
Modem is an example of communication hardware – an electronic device that makes possible the transmission of data to or from computer via telephone or other communication lines.

Hanna and Heather Craig from Alaska have invented a new winter rescue device: a 1.2 metre-long robot called the Ice Crawler. The robot is designed to take a rope to a person in a dangerous situation, for example, on thin ice or very soft snow.
 The Ice Crawler’s body consists of two tracks made of silicon-reinforced rubber, which is very strong and flexible even at extremely cold temperatures. This means the robot can move over ice, snow or rough ground without getting stuck. The Ice Crawler is operated by a control panel. This allows the rescue team to stay at a safe distance from the victim. The control panel enables the user to steer the robot, move it forwards and backwards, and switch the power on and off. A plastic tube holds the rope that pulls the victim back to safety.

Hanna and Heather Craig, twin sisters aged seventeen from Alaska, have invented a new winter rescue device: a 1.2 metre-long robot called the Ice Crawler. The robot is designed to take a rope to a person in a dangerous situation, for example, on thin ice or very soft snow.
The robot runs on two 12-volt drive motors – one on each of the tracks. These are powered by a 12-volt battery. A plastic tube carries the control panel’s wiring. It also holds the rope that pulls the victim back to safety. A video camera is attached to the front of the robot. This helps the rescue team to see where the Ice Crawler is going in snowy conditions or on very rough ground.

Our solar system is over 4,500 million years old. In a solar system, the sun and the planets form at the same time. They form from a cloud of gases called nebula. A nebula rotates in space and the force of gravity pulls material to its centre. The nebula contracts and its centre gets hot. This hot centre becomes a star.
The outer part of the nebula is not so hot. When the temperature goes down the gases condense into particles of dust. The dust slowly sticks together and forms the planets. Life on our planet begins from the dust of a dying star.

4,500 million years A.C.: the planet temperature is very high. There are many volcanoes but there is no biological life. Meteorites fall from outer space and volcanic eruptions prepare the Earth crust. Gases from the volcanoes form the initial atmosphere. The temperature goes down, oxygen and hydrogen join and form the first lakes and oceans. Scientists believe that life begins in these waters.
