7. MEMORY Calculations
Binary Digit – 0 or 1 (bit)
4 bits = 1 word
8 bits = 2 words = 1 Byte
1024 Bytes = 1 kilo Byte (kB)
1024 kilo Byte = 1 mega Byte (MB)
1024 mega Byte = 1 giga Byte (GB)
1024 giga Byte = 1 Tera Byte (TB)

9. Analog VS Digital Computer
Normal (Human & Animal)Voice is Analog Signal.
Vibrations are Analog Signal.
Needed devices to convert analog signal to digital signal.
Computer can operate and store only in digital data.
But it can convert analog to digital and vice versa.
Simple example for a digital data is normal switch which
can be operated in any one of the two states(ON / OFF)
There are some hybrid computers which can operate in
Analog as well as digital data like Medical Scanners etc.,

Assume there are 10 equal size boxes and I am providing
you 1000 Re.1 coin.
You need to put those 1000 coins in the boxes in any
order you like.
Terms & Conditions.
You need to fill all the boxes, No box should be empty
before giving it to me.
I can ask you money in any whole number in two or three
times whose sum will not exceed to Rs.1000/
While giving for the money which I ask, you need to give
