Pipeline
Have you ever heard about a pipeline in computer technology? Guess what. Right. A pipeline is very close to a computer. But can you tell me what a pipeline is? Well, let me explain. A pipeline in a computer is a sequence of stages a computer uses to carry out instructions.
The CPU makes sure every stage in a pipeline is always operating on an instruction. As a stage of a pipeline in the CPU finishes manipulating an instruction, it hands its instruction to the next stage and gets another instruction from the stage before it, moving several instructions along the pipeline simultaneously. This process is more efficient than it would be if each instruction had to start at the first stage after the previous instruction finished the final stage.
Oh, I almost forgot, the more pipelines a CPU has, the faster it can execute instructions. A CPU with two or more pipelines is said to be a super pipelined or superscalar. Okay. Have you got it? Not yet. How about going to the library and searching for more explanations about a pipeline? See you and good luck.

Making Paper from Woodchips
Do you have any paper in your bag? It may seem like a silly question but do you know how to make paper? What is paper made of ? Right. And how about ‘wood chipping’? Have you ever heard about it? Well, wood chipping is a process used to obtain pulp and paper products from forest trees.
First of all, the tops and branches of the trees are cut out and then the logs are taken to the mill. At the mill, the bark of the logs is removed and the logs are taken to a chipper which cuts them into small pieces called woodchips. The woodchips are then screened to remove dirt and other impurities. Hmm…, at this stage they are either exported in this form or changed into the pulp by chemicals and heat. Oh, I almost forgot, the pulp is then bleached and the water content is removed. Finally, the pulp is rolled out to make paper.
Considering the complexity of making paper, let’s appreciate any paper on our hands. Use it more effectively.

How Fuel Warning Light Work?
Many cars, motorcycles and other modern vehicles have fuel warning light devices. the warning light is usually red which switches on automatically when the level of fuel in the tank is very low. The warning light gives the driver information about the amount of petrol in the tank. When the light switches on red, it tells the driver that the petrol in the tank is almost empty. Therefore he have to put more fuel into the tank. However do you know how the fuel warning works?
Well this is the way the fuel warning light work and gives the driver information about the accurate amount of the petrol in the tank. When the level of the fuel falls, the float inside the tank moves downwards. When this condition happens, the arm also moves downwards and it make the lever touch an electrical contact. This switches on the fuel light in the car dashboard.
The red light which appears in the fuel panel of the dashboard tells the driver that he needs more petrol for his car. When he pours more petrol into the tank, this condition makes the fuel level rise and it pushes the float upwards. In return it disconnects to the electrical contact and makes the red light switch off.



Why is Bali Famous for Tourism Object?
One of the famous tourism spots in Indonesia is Bali island. Bali lays at the part east of Java. Thousand domestic and foreign tourists visit Bali each month. Do you know why Bali island is so famous?
A lot of tourists like fresh natural environment. If that what they want, Bali is the best choice to visit. Bali has beautiful landscape dominated with green luxurious terrace fields. Moreover Bali give fantastic view; beautiful sunrise in Sanur and fascinating sunset in Kuta beach.
Beside the beautiful beach and panorama, domestic and foreign tourists also enjoy the balinese local genius arts such as; dances, puras, and temples. Most of these objects are amazing.
Like many other tourism objects, Bali also provide souvenir center which they can take home. Most balinese people are artists. They spend their time to apply skill and imagination through painting, carving dancing.
What make them more exposed is that most of them are English speaking people. That is why Bali is well-known all over the wold.

How Earthquakes Happen?
Earthquake is one of the most destroying natural disasters. Unluckily it often happens in several regions. Recently a horrible earthquake has shaken West Sumatra. It has brought great damages. Why did it occur? Do you know how an earthquake happens?
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves. It make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don’t just slide smoothly. The rocks are still pushing against each other, but not moving. After a while, the rocks break because of all the pressure that’s built up. When the rocks break, the earthquake occurs.
During the earthquake and afterward, the plates or blocks of rock start moving, and they continue to move until they get stuck again. The spot underground where the rock breaks is called the focus of the earthquake. The place right above the focus is called the epicenter of the earthquake.

How do seasons happen?
Seasons come to us regularly. We have probably noticed that it gets warmer in summer or dry season while it get colder in the winter or wet season. However do we know how these seasons change?
Seasons happen and change every year. This happens because the earth tilts back and forth as it goes around the sun. During the summer, the earth tilts toward the sun. It makes half of the earth hotter. this condition is what we call summer. During the other half of the year, the earth tilts away from the sun. As a result, it makes that half of the earth cooler. This cool condition is then what we call winter.
The different parts of the world have the same seasons at different times. In the northern half of the world , winter happens during the months of December, January and February. The regions are such North America and Europe. In the other hand, the southern half of the world have winter during the months of June, July and August.The regions are like South America and Australia. How does this difference happen? The same season happens at different times because the top and bottom halves of the earth tilt away from the sun at different times.

How Cell Phones Work
A cell phone is a great gadget in this modern world. What is a cell phone? A cell phone is actually a radio in certain way. Like a radio, by a cell phone we can communicate to other people in real time. Million people use cell phone for their communication. Even nowadays, people use cell phones to communicate in voice, written and data. Alexander Graham Bell is the person who make great change in the way people communicate to each other. He invented a telephone in 1876. While wireless radio was formally known in 18994 presented by Guglielmo Marconi. By these two technologies, then a cell phone was born. However do you know how actually cell phones work?
This short explanation on how a cell phone work is really wonderful. A cell phone or in long term “cellular telephone’ works by transmitting signals of radio to towers of cellular. The towers are networked to a central switching station. The connection usually uses wire, fiber optic-cables, or microwave.
Then the central switching station which handles calls in certain given area is directed connected to the wire-based telephone system. Cellulars are pick up by the towers and relayed to another cellular telephone user or the user of wire-based telephone network.
The towers vary in the capacity and capability to receive signals. Some can receive the signal from short distance and the others can receive more distance. However, there are usually more than one tower in certain given area so that the system can handle the increasing telephone traffic.

How does Rain Happen?
Rain is the primary source of fresh water for most areas of the world, providing suitable conditions for diverse ecosystems, as well as water for hydroelectric power plants and crop irrigation.
The phenomenon of rain is actually a water circle. The concept of the water cycle involves the sun heating the Earth’s surface water and causing the surface water to evaporate. The water vapor rises into the Earth’s atmosphere. The water in the atmosphere cools and condenses into liquid droplets. The droplets grow until they are heavy and fall to the earth as precipitation which can be in the form of rain or snow.
However, not all rain reaches the surface. Some evaporates while falling through dry air. This is called virga, a phenomenon which is often seen in hot, dry desert regions.

Where Does Rain Come from?
Rain always comes from clouds. But where do clouds come from? How does all that water get into the sky?
Think about your bathroom. There is hot water in your bath. Steam goes up from the hot water. The steam makes small clouds in the bathroom. These warm clouds meet the cold walls and windows, and then we see small drops of water on the walls and windows.
The world is like your bathroom. The water in the oceans is warm when the sun shines on it. Some of this water goes up into the sky and makes clouds. The wind carries the clouds for hundreds of kilometres. Then the clouds meet cold air in the sky, and we see drops of water. The drops of water are rain.
The rain falls and runs into rivers. Rivers run into oceans. And the water from oceans makes clouds and more rain. So water is always moving from oceans to clouds to rain to rivers to oceans. So the rain on your head was on other heads before! The water in your garden was in other gardens in other countries.

Tsunami
The term of “tsunami” comes from the Japanese which means harbour (“tsu”) and wave (“nami”). A tsunami is a series of waves generated when water in a lake or a sea is rapidly displaced on a massive scale.
A tsunami can be generated when the sea floor abruptly deforms and vertically displaces the overlying water. Such large vertical movements of the earth’s crust can occur at plate boundaries. Subduction of earthquakes are particularly effective in generating tsunami, and occur where denser oceanic plates slip under continental plates. As the displaced water mass moves under the influence of gravity to regain its equilibrium, it radiates across the ocean like ripples on a pond.
Tsunami always bring great damage. Most of the damage is caused by the huge mass of water behind the initial wave front, as the height of the sea keeps rising fast and floods powerfully into the coastal area.

Cancer
What is cancer? It is actually a group of more than one hundred separate diseases. Most of us are fear from cancer It is reasonable because next to heart disease, cancer is the second leading cause of death.
Cancer cells come from normal cells because of mutations of DNA. Those mutations can occur spontaneously. The mutations may be also induced by other factors such as: nuclear and electromagnetic radiation, viruses, bacteria and fungi, parasites, heat, chemicals in the air, water and food, mechanical cell-level injury, free radicals, evolution and ageing of DNA, etc. All such factors can produce mutations that may start cancer.
Cancer cells are formed continuously in the organism. It is estimated that there are about 10,000 cancer cells at any given time in a healthy person. Why do some result in macroscopic-level cancers and some do not? First, not all damaged cells can multiply and many of them die quickly. Second, those which potentially divide and form cancer are effectively destroyed by the mechanisms available to the immune system.
Therefore cancer develops if the immune system is not working properly or the amount of cells produced is too great for the immune system to eliminate.
