Gig is short for Gigabyte. It’s a measure of quantity of information.
Just a Little Bit
A ‘bit’ is the smallest unit of measurement in a binary system, which a computer uses to communicate internally using only ‘0′ and ‘1′. Early systems started with 8bits ‘01010101′ and have slowly started including more and more bits, to the point where the most current systems operate with 64bits.
- Kilobyte (KB) = 1,024 bytes
- Megabyte (MB) = 1,024 KB
- Gigabyte (GB) = 1,000 MB
- Terrabyte (TB) = 1,000 GB
- Petabyte (PB) = 1,000 TB
- Exabyte (EB) = 1,000 PB
- Zettabyte (ZB) = 1,000 EB
- Yottabyte (YB) = 1,000 ZB
And on and on it goes. Computers, as they get more and more powerful require more and more memory.

Just a little technicality here;
1 B = 8 b (Always, regardless of disk formatting, e.g. 32 bit, 64 bit. The formatting determines the addressing system.)
1 kB = 1,024 B
1 MB = 1,024 kB = 1,048,576 B
Here is where they go from 1024 multipliers to 1000s. It was an advertising trick to sell less for more.
1 GB = 1,000 MB = 1,024,000 kB = 1,048,576,000 B
1 PB = 1,000 GB etc.
Does it really matter? Not really. Just thought I’d give you some pointers.
Thanks for fact checking my original post. The post will be updated to reflect your numbers
