Differences between LPG and PGA

the point is he has a question to answer for his computing course, and wants us to answer it for him, it'd be much better for him if he learnt how to research stuff properly and found out for himself/herself. There's 2-3/day like this. There was one yesterday along the lines of:
explain all about AA, and which settings you should use for a high power system and which you would use fo a low powered system. No mention of the actual systems, or the software being used.
In a way if this is the kind of education being offered then it just keeps the competition low, but the lack of ability to help educate themselves is shocking.
He's made it to here, but can't make it to wikipedia?
learn to fish! is the message i'm trying to put across.

@OP you need to be a little more specific with your question.

PGA can stand for a number of things in terms of computers and electronics:

Pin grid array- a type of packaging for integrated circuits

Programmable gain amplifier, an amplifier whose gain can be changed during its operation

Programmable gate array, a semiconductor device containing programmable logic components and programmable interconnects (vast majority of today's PGAs are field-programmable gate arrays, or FPGAs)

------

LPG - Not even sure what this is?

Im guessing maybe your asking for the difference's between LGA and PGA? Which basically are different CPU pin-outs. LGA standing for Land Grid Array, and PGA standing for Pin Grid Array. LGA is flat, like small gold "bumps", PGA is pins.
