Unlike the human brain, it can only understand and operate on 'words' of a fixed length. This might sound confusing to you because you have a human brain (I hope) (and that is a good thing <sub>probably</sub>). Let's consider a wordle fanatic who only understands words that are 5 characters long. If you want to get something across, you would have to break your sentences and pad them so that it is all 5 characters long.

**Hello did you sleep today** would become **HELLO DIDYO USLEE PTODA Y$$$$** to which they might reply **IDIDN OTSLE EPTOD AY$$$** which when decoded would be (left as an exercise to the reader!). **Hello did you sleep today?** would become **HELLO DIDYO USLEE PTODA Yxxxx** to which they might reply **IDIDN OTSLE EPTOD AYxxx** which when decoded would be (left as an exercise to the reader!).
Notice the trailing **$** used to pad the word making it 5 characters long. Notice the trailing **x** used to pad the word making it 5 characters long.
Processors would operate similarly, except that they only have 2 alphabets, each one called a `bit`. There are only 2 `bit`s - **0** and **1**. Some example words using this alphabet set are Processors would operate similarly, except that they only have 2 alphabets, each one called a `bit`. There are only 2 `bit`s - **0** and **1**.

Recall that computers work well with powers of 2. So instead of a 33-bit computer, the next processor type is instead a 64-bit processor. Recall that computers work well with powers of 2. So instead of a 33-bit computer, the next processor type is instead a 64-bit processor.

When the human race is captured by the robot overlords, they might want to map every particle in the known universe which is around 7 octillion, and hold everything in the RAM for real time tracking.

But that only uses up 92 of the 128 bits. (2^92 is around 7 octillion). They can use the remaining 38 bits to map the particles in alternate universes. 38 bits can address 10 billion things. This **SUPER COMPUTER** can therefore be used to track all the particles in 10 billion universes. But that only uses up 92 of the 128 bits. (2^92 is around 7 octillion).
