Kilobytes, Megabytes, Gigabytes and Terabytes

Hey everybody!
Hope y'all are having a happy Friday so far! Today I want to compare file sizes and explain what bytes are. Remember the old days when we had floppys, and 3.5 disks. Wow, how far we have come along in technology.

Today we have Megabytes, Gigabytes and Terabytes. Big, Bigger, and Biggest. These are units of digital information storage. Here is a summary of what each capacity is.

8 bits = 1 byte
1024 bytes = 1 kilobyte (kb)
1024 kb = 1 Megabyte (Mb)
1024 Mb = 1 Gigabyte (Gb)
1024 Gb = 1 Terabyte (Tb)

These days we are more digital than ever, so we require more space and convenience for storage of our photos and/or digital files for printing. Think of it like this, most email address cannot accept an attachment greater than 5 MB or megabytes which is actually a small file. It doesn't take up much memory and can be easily emailed (most of the time this is a low resolution version of the parent file).

A standard CD to burn music and files on, is about 700 MB, which is about 80 minutes of music. You can usually burn a whole music cd to one of these. A standard DVD is 4.7 GB and 120 minutes, which can hold a full length movie. Most of the time in printing we get files on DVDs, they are usually too big for a standard CD. Of course you can buy memory sticks these days with 2 Gigs or more. Amazing how many photos can be taken on a 2 gigabyte digital camera.

I have not actually used Terabyte storage items yet but will be looking into it for backups for our storage system in printing. I am sure as time goes on there will be even bigger bytes. But for now I hope this compares the sizes and explains what bytes are. Have a great weekend everyone!
