Bits are the lowest unit of memory. A byte is 8 bits. A kilobyte is 1024 bytes. I could continue on like this, but the chart below is quite useful. It will look scary to some, but really it's quite fascinating.
Computers in this day and age usually come with gigabyte (GB) hard drives (around 40 GB to 500 GB). Most people don't need more than 150 GB, and even that's saying much. (Check out the "Some Backup Advice" entry for info on storage space).
But more recently, computers can hold 2 terabytes (2000 GB) of space (most likely being a combination of multiple hard drives). I would say that 95% of the people who use computers frequently don't need this huge amount of space. Can you believe that there's things larger than a terabyte?
As technology advances though, we might have applications that take up larger amounts of space, so we might eventually consider 2 terabytes as primitive as storing 2 megabytes.
Here are some fun facts that gives you an idea of how much information these bytes can hold:
