So to work out the speed of what your meant to be getting for internet you divide it by 8? so if you have 80MB connection you should be getting 10MB download speed? also how do you calculate upload speed?

Also can someone explain to me how 1gb can be 1024 MB and 1000MB I was always teach at college that 1mb was 1024 KB, 1gb was 1024MB and 1TB is 1024 GB can someone explain why people say it is 1000?


As far as I can tell that is correct...divide by 8 to find the speed you should actually be downloading...As for upload, divide by 8 as well?...They are being measured in the same unit, so wouldn't it make sence to divide by the same number?...That's what I THINK anyways...can someone confirm this?

People usually round it out (at least I do)...Its easier to remember\add\divide\whatever by 1000, then it is by 1024...Its also easier when your talking with someone who is not very, or at all, familiar with data units (tb, gb, mb, kb, etc)...Personlly I use 1000 all the time, but if you wanna be accurate, you should use 1024...

even dividing by 8 to get MB/s rather than mbps will not get your actual download speed. That is more of a theoretical maximum, you will get slower than that. Though hopefully not too much slower.

Always does your maths accurately! Just use a calculator if you need one.

What if I don't have a calculator or my phone at my disposal? What if I don't wanna waste time being accurate, I just want a quick estimation? I don't really care about those extra 24mb...just makes all the math a pain... but of course if you REALLY want to be accurate, then go ahead and spend 5x longer to figure out the addition...even longer for multiplication...

The k being 1000 stams from the metric system. Since a kilogram is 1000 gram it's pretty normal to say that a kilobyte is 1000 bytes.
However computers store data in bits, so they have an easier way of calculating 1024 (2^10) instead of 1000, so the people using computers prefered to use 1024 for it.
Since there was so much confusion in this and kilo was already in the metric system, it's now common to say that 1 kB equals 1000 bytes.
Also another standard was made for the binary ones, like KiBibyte (KiB), where Bi stands for Binary and 1 KiB equals 1024 bytes.

The advertised speed should definitely be your actual download speed (the Mbps divided 8), at least in cases like Cable and Fiber, since that is what your ISP is selling you. Only in cases like DSL, where your speed is strongly depending on how close you are to the DSLAM, your speed won't be what your ISP is telling you, since they can only offer a "maximum" speed. And well, of course some ISP's are just assholes and oversell their products while they don't actually have the backbone to support all traffic or actually traffic shape everything so your speeds might still be awful for P2P and the like.

wait... are you saying that even the ISP's use the 1000 for K? im now curious as to which way they interpret K...

:O I did not know this was common. People are so lazy/stupid.

well i for one just noticed while working on 2 different machines one ubuntu on fedora that one uses the 1000 for K and the other 1024 and Ki >.< why use different ones?!?! but at least they use proper notation....

It works the same for bits: kilobits = 1000 bits and kibibits = 1024 bits.
But with bits you don't really need a binary system, since they already are bits :P
ISP's would always use 1000's since they could sell more Mbit/sec that way while it is less for them ;) Same with HD manufacturers. RAM suppliers do seem to have 1024's labeled, although wrongly (in GB instead of GiB), due to historic reason I suppose.

Also if you want to do it perfectly right, a kilo should be a lowercase k. So it's like kB, kb, kbps, kbit/s. Though the rest is still uppercase.

Something even more confusing is that Micro$oft uses kB for Windows while it is actually using 1024 bytes in their OS. My guess is that it's because they've used it like that since their first DOS and didn't wanna confuse people by "magically increasing your diskspace" with a new version. :P
This is also the biggest reason why your hard drives in Windows always look smaller than what they state on the labels. The rest that is missing is because of the file system. Though some drives do have less actual bytes than they label. :(

11) I have the Noctua NH-D14, and as some of you may now...this bitch is CHUUUUNKY...its so chunky that it nearly cover my PCIE16 slot on my Asus M5A99XEVO motherboard...luckily my motherboard has 3 PCIE16 slots :D...My GPU is arriving on Monday, but I don't think it will fit into PCIE16 Slot 1 (Because the Noctua NH-D14)...So my question...Is it O.K to put my GPU in PCIE16 Slot 2? Will they're be a performance difference? Will they're be ANY difference?

Motherboards are configured differently, so keep in mind that the answer to your question won't always be the same.

The Asus M5A99XEVO has three PCI-e x16 slots, but the black one is only capable of providing the bandwidth of an x4 slot. This means that this third slot will offer worse performance for cards that need lots of bandwidth (i.e. modern video cards, which may get bottlenecked).

As for the other slots, they share their available bandwidth. So, if you only use one of the blue/white PCI-e x16 slots, you will get the total available bandwidth there (x16), but if you use both interfaces simultaneously (i.e. with two cards in SLI/CrossFire), each slot will only get half the bandwidth (x8/x8).

You caught me while I was editing my post. >.<

I went into a little more detail.
