Tech Term of the Week #1 at 4:02 PM

ok i know this is kinda early but i kinda realized that i dont wanna get up earlier than i have to ....

ok this week's word is DDR RAM! often shortened to just ram
no its not dance dance revolution, would be pretty awesome if you had a ram that could play ddr....

anyways DDR RAM stands for double data rate random access memory. This is the stuff that stores everything your computer is doing when its on. So lets go through what the name stands for. The double data rate refers to the technology called double pumping, which i think is that thing Tiger Woods does...lol... ok jokes aside, computers work by going through cycles of high voltage and low voltage, and a cycle consists of one up and down voltage. Double pumping however allowed us to use the high and low voltages of one cycle to transmit two pieces of information instead of one, thus double pumping, and that leads to double data rate, aka DDR

ok moving on to the RAM part, AHAH GET IT RAMPARTS AHAHAHAHAHAHAA IM SO FUNNY!

ok so basically you need ram because you need some kinda of storage that can read and write rly rly fast so that your cpu wont be stuck waiting for you storage decide to load and write data. Hence the name random access memory, it works well when you randomly need to read or write data. Now you might ask me, hey isn't that what my hard drive is used for? Reading and storing data? Well yes but your hard drives are painfully slow compared to your ram, even in comparison the fastest hard drive right now. So a little bit of numbers to put this into perspective.

The faster consumer hard drive right now is the WD Velociraptors hard drives
which spin at 10000 rpm. It reads at 130 MB/s and writes are 55MB/s.

the slowest version of ram DDR-200 has peak transfer rates of 1600MB/s up and down
and the faster ram, DDR3-1600 has transfer rates of 12800MB/s, aka hella fast.

ok im getting tired of writing so ima sum up ddr ddr2, and ddr3 in one sentence.

basically the differences are that the memory cells on the sucessive (is that the right word?) has double the pipelines out thus allow faster data transfer.

and thats this weeks tech term
