Your memory (as in RAM) won't be 1TB.

You mean your storage.

Actually, to be actuate it's 1024 Gb = 1tb, you have 24 GBs more.Its estimated to 1000GBS but it can be 1000GBN exactly in some drives but for purposes of virtualisation and binary representations(complex stuff) it would be 1024GB.so 2TB would be 2048GB SEE:http://www.whatsabyte.com/

I'm surprised that your the only one that knows/wrote that it's actually 1024. This is a tech Q&A site I would have thought that everyone here would have known it.

I knew it but then you get bombarded with the questions as to why. And I felt that it was better to give him/her the rounded number to not confuse them.

Well it's easy enough to explain. You could have added it to your answer just like HHBones did. I figured some of you just did it to not confuse others and that is why I wrote "knows/wrote".

Due to marketing, the drives are actually rounded down so that everything is 1000 instead of 1024. Not to mention the system reserved part of the drives. Because of this, a 750GB is actually 698GB and a 500 is actually 465GB. Is very deceptive but if you already know about, you know what to expect.

1 Terabyte (TB) is 1024 Gigabytes (GB) 2 Terabytes is 2048 Gigabytes. Simple really.

1TB= 1 Terabyte 2TB= 2 Terabyte which are the size of a Hard Drive. Think of it as 2 5ooGB drives

1TB means 1 Terabyte. Which equals around 1,000 GB. A 2 TB hard drive means 2,000 GB.

It is the new big storage size.

I think you're confused. Usually when you're talking about upgrading the "memory" on a computer, you're talking about RAM. This is usually represented in gigabytes, somewhere between 1gb and maybe 6gb if it'sa newer machine.

If you see a number like 500 gb or 1 tb, you're talking about the hard disk, or the storage medium.

The difference is that the RAM, or random access memory, it temporary and goes away when the computer is powered down. The hard disk is for storage, it's where the computer stores all the data files and programs.

If you can tell us the brand and model of the computer, we could help you figure out what type of memory it takes. Usually there is a sticker on the back with the exact model number, or if its a laptop it may be on the bottom.

He still doesn't have the concept of it.

One byte is the space needed to store a character, or 8 bits (1 or 0) on most machines, which work in ASCII (some, like Macintosh, use Unicode, which is more advanced, but a byte is still standardized to 8 bits).

This is because computers have their roots in binary code. Every second, billions of 32- or 64-bit opcodes flash through your processor.

Because everything is based in binary, it's only fitting to measure storage and memory in powers of 2. So, one kilobyte is 1024 bytes, or 2^11. This was chosen because it's the closest to 1000, a nice decimal measure, hence the name kilobyte. Next is megabyte, or 1024 kilobytes, which works out to be 1048576 bytes. Then come megabytes, then gigabytes, terabytes. In other words, one terabyte is mostly estimated to be 1 trillion bytes of storage (so, you can store, theoretically, 1 trillion different letters on the hard drive).

1TB stands for 1 Tera Bytes. 1TB is a 1000GB. Thats a lot of storage.

@Juan Arias M: what is with the "JAJAJA" at the end of what look like sentences? You can use a period.

It's a lot, not allot.

Unless he's talking about allotted space on a hard drive...

Hey guys, please note that TB and Tb are two different units. We don't need to confuse new people in this thread.

In that instance, 1TB would be twice your 500GB Hard drive, however, if you do opt to purchase such a large hard drive for your computer, it's very important that you split the drive up into at least 2 partitions, for best practice purposes.
