1.Some Basics Before Starting Java


Before we go forward to learn Java,we must know about Computers and how it understands user Input...

lets see....

What is Computer?
thinking........
"The Computer is an Electronic Device capable of  performing Computations."

We Human having Heart to live in this World...In the same way Computer must have some heart to live in this world...How it is possible?Even computer having Heart?you may ask me,hey santhosh are you gone mad,how could it be possible?

Yeah its Possible by using Processor...without Processor our system wont work... 

Okay santhosh,but you have written computer is an Electronic device then how  it can understand TEXT,IMAGES,AUDIOS and VIDEOS?
Great Question...I am having answer for this too...


Just look at this above diagram, Computer can understands only Electric signals...In our diagram we are passing 5 volt current, its simply binary 1...Similarly we are passing 0 volt current, its simply binary 0...Our Computer is continuously bombarded with these electronic signal/process...
*8 bits of such signals are grouped together..
*Symbol  "#" is represented by 10101010(8 bits)..
I hope you guys got it upto we discussed...Next we will see some overview of Assembly language...
