    Give this man "Best Answer" he's right on the money.
  4. Hi :)

    Homework again....


    The answer is ********* by the way...and its not transistors...


    All the best Brett :)

    :lol:
  6. yay homework questions!

    If there is one "basic" component of a CPU it's the MOSFET transistor. However it is possible to construct digital devices without any sort of transistor
  7. Yes, transistors and Oompa Loompas are the basic CPU components.

    How? This is not a homework question :) , just a curiosity in what you are referring to. I have an electrical engineering background so please don't spare the technical terms.

    It's possible to create basic motionless OR and AND gates using just a pull-up/pull-down resistor and two or more PN diodes. The use of a pull-up/pull-down resistor in any internal logic is highly ill-advised because its almost always better to use a CMOS network to reduce switching time and static power dissipation.

    Going back a few more decades it's possible to use magnetic relay switches instead. These are functionally similar to MOSFETS but are extremely slow and actually have moving parts.

    I got ya, Pull up/down resistors and diodes is a way to create logic. That's a good observation.

    As far as relays, that's a transistor in my book, although not by wiki's first sentence of the transistor page: "A transistor is a semiconductor device used to amplify and switch electronic signals and power". The requirement on being a semi-conductor, IMO, is not true. Wiki even talks about vacuum tubes as transistors, hence breaking the definition. Eh, that's what happens with multiple authors. On a side note, one could also use plasma as a switch. Some people doing research related to my group are trying to do this with a micro plasma.
  11. MOSFETS and relays are both voltage controlled switches. Thus they have the same logical function and can be used to implement similar devices without much deviation. Vacuum tubes are interesting and have a lot in common with BJTs that make them suitable for analog applications.

    Plasma can be used as a switch, as can photonics. It's interesting to see how many different physical domains can be used to implement the same logical domain.
  12. Hi :)

    THINK much smaller....

    All the best Brett :)
  13. If by "*********" you mean "electrons" you would be only half correct. Holes are equally important charge carries in CMOS circuits ;)

    He probably meant silicon.

    In more general terms, it could also be 'substrate' since every IC starts with a substrate (wafer) which is not necessarily silicon.

    The most basic component is a transistor. A transistor is like a variable relay. I'd say its the most important creation to all modern day electronics and technology.
