Firstly What is Bits and Bytes?
Bits :
The concept of a bit can be understood as a value of either 1 or 0, on or off, yes or no, true or false, or encoded by a switch or toggle of some kind.
Bytes :
A byte is often a computer's smallest addressable memory unit. In most computers this is an ordered sequence of eight bits or binary digits that can represent one of 256 possible values. Most recent computers process information in 8-bit units, or some other multiple thereof (such as 16, 32, or 64 bits) at a time. A group of 8 bits is now widely used as a fundamental unit, and is generally called a 'byte' (or sometimes octet).

PageRank is a numeric value that represents how important a page is on the web. Google figures that when one page links to another page, it is effectively casting a vote for the other page. The more votes that are cast for a page, the more important the page must be. Also, the importance of the page that is casting the vote determines how important the vote itself is. Google calculates a page's importance from the votes cast for it. How important each vote is taken into account when a page's PageRank is calculated.
PageRank is Google's way of deciding a page's importance. It matters because it is one of the factors that determines a page's ranking in the search results. It isn't the only factor that Google uses to rank pages, but it is an important one.
