| This video was about the components and functions that take place in the CPU. The video creates a visual of more or less where the components are, how they connect and what’s happening inside the CPU. The Information in this video was very specific and explained all the different elements of a CPU very well. I learned that there are a lot of things happening all simultaneously in the CPU. I also learned about the different components, their functions and placements of them inside. What I thought to be a little confusing was the details about Cache. All the different locations of the cache and different kinds of cache are too ...view middle of the document...

Two major Manufactures are:
* Intel
* AMD
Organization
* System Bus- Carry’s information in and out CPU
* When enters CPU, it’s called the Font side Bus (Usually uses a 64 bit wide data path)
* Connects to controllers which control basic functions, components and communication
* Internal Bus (usually a 32 bite wide data path) connects Controllers to ALU
* ALU- Preforms complex calculation(CPUs can include one or more)
* Back side bus connects the ALU to the Cache and the Cache to the Controllers
* Cache- Internal memory

Speeds
* Processor- measured in GHz
* System Bus- measured in MGz
* Multiplier- Ratio between processor & system bus (System bus x Multiplier = processor speed)
Differences between:
* Multiprocessing-using multiple ALU’s
* Multiple Processors- more than one CPU on single...
