PC133 is an SDRAM standard. SDRAM is a type of RAM.
No. PC133 SDRAM and DDR1 ram are different in many ways.
PC 3200/DDR 400
PC-100 or PC-133 SDRAM will not fit into a DDR SDRAM slot. If you look at the bottom edge you will see that the number of notches and the spacing of them are completely different. Even if they did use the same sockets, they are not at all compatible with each other, to the point that if you have a motherboard with both sockets you would only be able to use one type of RAM at a time.
The DDR DIMM is an older type of RAM. DDR DIMM is not compatible with other kinds of RAM which is why a person that has an older PC has to choose a DDR DIMM memory as a replacement for one that broke.
Unfortunately you can not. DDR and DDR2 have a different pin arrangement and they will never work in each others slots.
No, you cannot. PC2 is ddr2 type of memory when PC is ddr. Those types are not compatible.

Depending on your motherboard it is most likely because most motherboards can only use one type of ram at a time. So you can only use ddr with more ddr to see more than one stick of ram.
Not both at the same time. Most motherboards will be able to support both types of RAM but DDR RAM is much better, due to the double data capability it has. Since RAM prices are quite cheap it would be better if you throw out your SD RAM and buy DDR. No you cannot use both ddr ram and sd ram on the same pc. You have to use either or depending on the motherboard. The slots are different. You can determine what type of memory you have by entering setup in the bios when you turn on your pc. DDR Ram has a slot in the very center of the chip that forms to the slot you plug it into. SD ram has a slot on the chip off set the middle. Hope this answers your question.

No. DDR RAM cannot be used to replace or upgrade a PC133 module.
The Kingston Technology DDR is a good brand for any computer PC Kingston Value is the best choice.
Double sided PC memory is a RAM module that posses two edges (a rising and a falling edge) on which data is received/sent. An example is DDR and DDR2 RAM.
