Binary System.

A Computer understands only  1 or 0.Imagine a switch , if it is On -->1 otherwise--> 0.This system is called Binary system.0 And 1 are together termed as  bits.Computer consists of a lots of transistors(imagine a switch).Often heard of the CPU(central processing system)...It  is the brain of a computer.Hence, if your CPU is faster it means more number crunching,more switches hence faster output.It works this way--

binary-->decimal
0-->0
1-->1
10-->2(eh...?)------->(Just Chill !!!  1st digit *2^0+2nd digit*2^1+3rd digit*2^2.........go on make your own..:).....:))
11-->3
100-->4
101-->5
....................

Now let me ask you a question--->
what is the maximum number you can make with the 8 digit binary...no no i dunno wanna say...........................11111111...that would be so obvious ...:P..what is the decimal equivalent of that number..? try and scroll down for knowing the answer..;)..atleast a rough estimation mate..:)

You know how your computer accepts A,B,C..just wait ..

A->1000001(65 in decimal)
B->1000010


RAM(random access memory) is the place where your programs actually run.

The answer to the question is 255
