Electronics

There are different types of electronics which are commonly used in daily life even in different aspects of life as well. Toys, military equipments, communication, home electronics, cars satellite and others.  This is only an overall list of products which contain electronics. In other words electronics plays very important role to our life. Even we wake up with electronic clock even we drink coffee which is made in electronic machine. Even computer is a big example of very unique electric machine which is commonly used now these days. We listen music on sound systems and even when we go to sleep then we adjust our electronic watch for tomorrow morning. Just hundred years ago situation of world was totally change and now these days it’s really change even creation of different things made our life as easier as possible.

Experimental and theoretical study of electricity started in 18th and 19th centuries that enabled the development of first electronic machine and a vast use of electricity as well.

Electronic system has become more complex now these days. Every thing is unique in its sense. Usage of electronics is increasing in our life day by day because this is era of technology. Electronic system became more complex and smart. Computers included hundred of thousands of transistor. Their number rapidly increased during next ten years. In 1970 the number was 1,000 in a chip and the result of hard work of physicists, electronics and mechanical engineers was developing and producing of first microprocessor with memory interface in 1971.This event was the beginning of computerization and smart digital electronics.

There are different types of electronic circuits. Analog circuits, Digital circuits. If we want deep study in electronics then we definitely have to be known with mathematics of circuit analysis.

Electricity is cheap, clean and safe source of energy producing. This is cheap in normal use but to use it for heating purposes it’s really very expensive. Electricity made us our life more convenient.
 
If there is advantages of electricity at the same time there are some disadvantages as well. For example if we sit in front of computer all the day we will see so tired when will go for off.  Main disadvantage of electricity is that this is very dangerous in case of any shock or injury.

Electricity keeps us warm even cooks our food. Even in traveling electricity plays very important role. Just like traveling buses or helicopters etc having electric engines. In other words we can say that electricity makes very important role to making our lives easier. But at the same time if we see disadvantages then we came to know that electronics make fumes which are really dangerous to our health. Electricity also make us soft lazy and flat.  But now these days no one can survive without electricity. Electricity lightens our life we can’t live now without it. In this era we are nothing without electricity. In old ages there was no electricity but as with the passage of time scientist introduced this unique thing which is now as needy for life as water for us.
