Machinery of around us
Life of our modern are supported by a lot of our machine. I feel very inconvenient car, air conditioning, TV, and mobile phones, not just any one.
Personal computer is present must be in order to gather information, utilization, processing, and transmits in that.
People who not live without PC also I think in get inside.
The history of the personal computer

- 1990s
- Adopted the PC / AT standard of IBM, PC / AT compatible machine flows from abroad, PC9800 series of proprietary went lost its market gradually. I will continue to migrate to 32-bit personal computer gradually 16-bit personal computer by this.
- 1995

Question to a PC current
PC The current surprise in spite of many parts have been used in high-performance, to being sold cheap surprising.
Personal computer was very expensive also, seems to have succeeded in reducing costs by combining an inexpensive parts are standardized in the old days.
Thanks that is standardized, you can You can add peripherals variety, it is more convenient machine to the PC simple . Also, I heard from by exchanging parts also inside the computer, and can be modified to a PC that is powered up simple .
Book but verification by decomposing the actual contents of the PC is said to be simple , whether really easy unexpectedly it is the purpose of the site.
Extended with peripheral devices
I will add as a machine to increase the useful function by PC peripherals personal computer. Currently, it is used most standard USB that it is.
※I will not go for the peripheral equipment in this site.
Internal structure of the personal computer
The personal computer itself current with a focus on ATX standard I have made based. (Super) the figure below is a simple internal structure of the personal computer. I will continue to focus on the parts that have been standardized these in this site.
