Why blog Name is Zero Equal to Infinite
Here is the points of view why i gave this name to my blog

1. Mathematical explanation 1:-We have seen in basic mathematics that when there is a function f(x)=C/x
and x approaches toward 0 the value of function f(x) approaches toward infinite i.e limit x-->0 C/x = infinite.

2. Mathematical explanation 2:- Let us suppose we have strip of paper(11''by 3''), now make a circle using this strip by joining two ends but one end must be rotated by 180 degree before joining, now cut this circular strip/shape so that the width if the strip remains half that of the initial width. Now see, the width of the circular shape go on decreasing but the circumfrence of the shape go on increasing. Therefore one can say if the width of the paper will be zero the circuference of the circle will be infinite. But fact is that zero width is not achievabl, and hence the infinte circuference of circle.

3.General View:-What is our general view about infinite?. It is certainly what is not perceivable by our senses, it is the certainly indicates the limit of our senses. It is certainly indefinite, non-deterministic in nature. It is certainly where one can not reach. Now look at the zero. We initially/normally say that when nothing is there, the quantity is zero. But reconsider when there is nothing there, how can a question related to quantity be valid. Think seriously, we will see zero same complex/amazing as we think about infinite.

4. Spiritual 1:-
What is SMAADHI, it is a state where mind is free from any worldly thought, it is a state of SUNAY (zero), now whatever is percieved here in this state is the feeling of being oneness. When worldly thought deminishes, self emerges (JAB VICHAAR TIROHIT HOTE HEIN, TO SAVYAM AAKAAR LETAA HAI), whose realization/dimesions/scope is infinite.

5. Spiritual 2:-Conciousness is malacious due to five DOSHH (KAMA, KRODH,MOH,LOBH, and IERSHHA), when degree of these DOSHHA approaches to zero, the state of conciousness approache to infinite.

6.
Spiritual 3:- Every one individual has zero strength as compared with the infite strength of nature, ones wisdom seems to be zero/uncapable to understand the infite's(GOD's) potential/scope/degree/functional/attriute. But it the individual who has capability to understand all these which in first instance seems impossible.

7. Scientific:-

Components of Central Processing Unit (CPU)
A CPU has following components:
1. Datapaths (such as ALUs and pipelines)
2. Control unit: logic which controls the datapaths
3. Memory components such as register files, caches
4. Clock circuitry such as clock drivers, PLLs, clock distribution networks
5. Pad transceiver circuitry
6. Logic gate cell library which is used to implement the logic

Phase-locked Loop(PLL)
A phase-locked loop or phase lock loop (PLL) is a control system that generates a signal that has a fixed relation to the phase of a "reference" signal. A phase-locked loop circuit responds to both the frequency and the phase of the input signals, automatically raising or lowering the frequency of a controlled oscillator until it is matched to the reference in both frequency and phase. A phase-locked loop is an example of a control system using negative feedback.

Pad transceiver circuitry
A transceiver circuit for an integrated circuit having a pad located therein, a receiving circuit connected to the pad for receiving digital data signals therefrom, a transmitting circuit connected to the pad for transmitting digital data signals to the pad, characterized by output resistance control means connected to said transmitting circuit and arranged to dynamically retain said output resistance of the transmitting circuit at a constant value during data signal transmission from said transmitting circuit.

Logic gate cell library
A standard cell library is a collection of low level logic functions such as AND, OR, INVERT, flip-flops, latches and buffers. These cells are realized as fixed height, variable width full custom cells. The key aspect with these libraries is that they are of a fixed height, which enables them to be placed in rows, easing the process of automated digital layout.
How Computer Cache works

Lets take a library as an example to understand how caching works. Imagine a large library but with only one librarian (the standard one CPU setup). The first person comes into the library and asks for a book titled "Lord of the Rings". The librarian goes off follows the path to the bookshelves (Memory Bus) retrieves the book and gives it to the person. The book is returned to the library once its finished with. Now without cache the book would be returned to the shelf. When the next person arrives and asks for "Lord of the Rings", the same process happens and takes the same amount of time.

But, if this library had a cache system then once the book was returned it would have been put on a shelf at the librarians desk. This way once the second person comes in and asks for "Lord of the Rings", the librarian only has to reach down to the shelf and retrieve the book. This significantly reduces the time it takes to retrieve the book. Back to computing this is the same idea, the data in the cache is retrieved much quicker. The computer uses its logic to determine which data is the most frequently accessed and keeps them books on the shelf so to speak.

Similarly, more level of caching desk (computer cache) can be possible which indeed the case for the modern computer systems architecturs.
