Yes, although you won't here DDR1 used by anyone.
Yes, DDR3 is type of RAM.
It means double-data-rate three synchronous dynamic random access memory or double-data-rate three synchronous dynamic RAM.
Short answer is no.They are not interchangeable.
DDR2 RAM is slightly smaller and has square chips. DDR1 RAM has rectangular chips.
DDR by a long shot
DDR 1
no it support only ddr1 ram
DDR. Technically, there is no "DDR1", only "DDR" and DDR2".

You are speaking about the RAM ? Just remove your old RAM from the slot. Buy a 1 GB RAM ( be carefull that your new RAM should be same frequency (FSB) that is supported by your motherboard and same size ( i.e. SD, DDR, or DDR1, or DDR2, or even now DDR3 or other ).
DDR 1 USE 184 PINS THE BEST THING IS TO TAKE DDR AND CHECK THE PIN AREA THAT IS GOLD PLATED YOU WILL FIND WRITTEN 1-96 AND OTHER SIDE 97 -184 THAT MEANS YOU ARE USING DDR1 DDR 2 USE 240 PINS SAME THING FOR DDR2 AND IT WRITTEN 240 MUSTAFA AHMED KHAN DDR 1 USE 184 PINS THE BEST THING IS TO TAKE DDR AND CHECK THE PIN AREA THAT IS GOLD PLATED YOU WILL FIND WRITTEN 1-96 AND OTHER SIDE 97 -184 THAT MEANS YOU ARE USING DDR1 DDR 2 USE 240 PINS SAME THING FOR DDR2 AND IT WRITTEN 240 MUSTAFA AHMED KHAN DDR 1 USE 184 PINS THE BEST THING IS TO TAKE DDR AND CHECK THE PIN AREA THAT IS GOLD PLATED YOU WILL FIND WRITTEN 1-96 AND OTHER SIDE 97 -184 THAT MEANS YOU ARE USING DDR1 DDR 2 USE 240 PINS SAME THING FOR DDR2 AND IT WRITTEN 240 MUSTAFA AHMED KHAN
DDR2 RAM is slightly smaller and has square chips. DDR1 RAM has rectangular chips.
It supports ddr (first generation - ddr1).
DDR has a 184-pin DIMM interface and DDR2 has 240. DDR2 runs cooler and has generally slower timings but is a lot faster than DDR in the end. DDR2 is capable of holding more ram on one DIMM.
