How Solar Cells Work

Solar panels are composed of many small solar cells. Each solar cell uses light to generate electricity.

Every day we see the electrical work. When a person opens a light, electrons through the wire, a bulb. Electronic that is flowing is electricity.

Solar cells using light make electrons. The battery is by sticking together of two different levels. The first layer is equipped with an electronic, electronic is prepared from the layer to the second level. The electrons take a second. It is ready to take more electronic.

When light shines on the ground floor of the electron, the electron jumps to the second-tier. It makes e-another move, which makes other electronic acts, and so on. So began a stream of electrons, or electricity.

About Networks

 Networks

 Hello hello... guys today I start my first post about  LAN WAN MAN VAN posts.stay tuned with us.So, what are they LAN WAN MAN VAN.These are Communication networks categorizes.Communication networks may be categorized in to four distinct groups depending upon the physical or geographical areas that they cover.These groups are :

• Local Area Networks (LAN)
• Wide Area Networks (WAN)
• Metropolitan Area Networks (MAN)
• Value Added Networks (VAN)

Basic communication are normally organized into a system or network and the design of these communications networks varies greatly depending upon  the general applications for which they are used.Different designs are used for different geographical,cost and operational requirements,which in turn dictate the type and range of equipment used.

Data communication systems are the electronic system that transmit Data Over communication lines from one location to another.

Previously telecommunications meant voice transmission over telephone lines.Today,much of telecommunication transmission is digital,from one computer to another computer.

 STAY TUNED FOR NEXT POST.

Medicine

Medicine

The practice of medicine is based on diagnosis and treatment.A hundred years ago,the physician felt the pulse and came to various conclusions about illnesses.

He had only a few instruments to diagnose a disease.Within the last A hundred years, medical technology developed.Now the physician has sophisticated medical instruments to diagnose diseases.

X-ray machine that was invented in 1895, came into regular use.It was invented by Wilhelm Rontgen.With the help of this machine the doctors were able to see the inside of the body and diagnose diseases.In 1973 the CAT scan machine was invented.With this invention medical science was revolutionized.The patient is kept inside the machine and the body is scanned by X-ray.

The E.C.G machine was invented during the last century.It is used to find out how the heart works.The damage caused by a heart attack can be measured on this machine.

Medical technology continues to develop very rapidly.Today the changes of the body can be observed and measured.These findings are the key to diagnosing diseases and deciding treatment.

Medical science and technology has developed so much that surgeons transplant organs from one body to another.Kidney transplantation was first attempted in 1902.Today it is a well established operation.Heart transplantation was first performed in South Africa,in 1967.It was done by the surgeon,Christian Barnard.

Satellite Communication

Hello visitors!!!!!!!!!!!Read following and up your Knowledge..

Have you looked at the sky on a cloudless clear night?What do you see there high up in the sky?There are millions of stars hiding the secrets of the universe.Among them them,if you look at the sky very carefully for sometime,you can see blinking stars moving from north to south or south to north and you will understand that their movement is very fast.What are they?Why are they moving so fast They are man made stars;they are called artificial satellites.

So.....I think to post today satellite Communication................An artificial satellite is a spacecraft.It is orbits the Earth at a fixed distance.Artificial satellite are sent to space on various purposes such as communication,remote sensing,military purpose,space astronomy.However,the main purpose of satellites is communication.They bring the world together.It is with the help of communication satellites that  we enjoy the thrill of Olympic Games,World cup football,Asians Games or the World Cup Cricket Finals How does CNN or BBC news come to us?How does the weather forecast come to us?They all are communicated with the help of satellites orbiting the Earth.

The first artificial satellite,Sputnik 1 was launched by Soviet Russia(USSR) on 4th October 1957.It was a competition between the USSR and the United States of America(USA) at the beginning.Later,other countries like France,China,India,,and japan too started launching their own satellites for various purposes,mainly for communication.In 1945 the honored Sri Lankan citizen Arthur C.Clarkemade a very famous statement about making communication possible with countries all over the world with the help of a spacecraft orbiting the Earth.The world became a single village as a result of satellite of satellite communication.There are commercial communication satellites like TEL STAR,INTELSAT etc.providing communication facilities for the whole world.

 Geostationary satellites orbit the Earth at a distance of 35900 Km and take 24 hours to orbit.That`s why they appear almost at the same time of the day in the sky.If you observe the sky for a few days you will be able to see these artificial starts orbiting the Earth every day at the same time.At the moment there are more than 3000 satellites orbiting the Earth.

 All these satellites communicate with communication stations build at various places on the Earth.Dish antennas are used to communicate between a satellite and communication center.In countries where there are satellite television services people can receive T.V.program-mes telecast by hundreds of T.V. stations all over the world with the help of a dish antenna.
