Design and manufacturing of computer chips is a advanced technology. Current technology uses micro-electronics of about 0.35 micron using aluminum as conductors and 0.25 micron sizes using copper as conductors of electrons. In near future the technology of 0.10 micron with copper and even nano-electronics will be used to make computer chips. Aluminum conductors will be phased out by copper on computer chips, as copper is a better conductor of electrons. In about 20 years from now, silicon chips will be phased out by molecular computers and bio chips which will be billions of times faster than silicon chips.
Molecules are a group of atoms.
And atoms are tiny particles which makes up everything that you see in this world. When the switch is ON it indicates 1, and when it is OFF it indicates 0. Table below shows the progress and future advancement trends of computer chips. In fact, any person in this world with a small low-cost PC can write software. It will be a great advantage to take the existing code and add missing features or enhancements to PostgreSQL and start using it immediately.
