I have been looking for a laptop just for checking my emails-downloading pictures and or songs-etc.
Nothing real important. I have a desktop for all bill paying and downloading for most things that I need to keep. I ran across one for sell thru a friend of mine . It has 256 in memory and 26 GB's. My sister has a laptop that is 512 in memory and 80 MB's. Which is bigger the MB's or the GB's?
Can anyone answer this for me please !!!

Thanks

One gigabyte is equal to 1,024 megabytes. Therefore GB is larger than MB. The one for sale is much 'smaller' than your sisters. Your sisters has twice the RAM(memory) and not quite 3 times the hard disk space (26 vs 80) in general terms. The 80 in GB not MB, I can assure you.

Megabyte is 1,000,000
Gigabyte is 1,000,000,000
Terabyte is 1,000,000,000,000

Million/Billion/trillion

Maybe an external hard drive?(USB)

Remember, it is all binary math, powers of two 2x2x2x2x2 etc


1 kilobyte is 1,024 bytes expressed in KB
I megabyte is 10 kilobytes 1,024,00 epressed in MB
I gigabyte is 10 kilobytes 1,024,000,000 expressed in GB

I used to teach this way back when to students who immediately forgot it all after the final exam
In the beginning there was the command line.

The difficulty is that there is no single standard adhered to by all.

Memory capacity is quoted on a fully binary tree - binary Meg & Gig (Mebibytes & Gibibytes):

http://physics.nist.gov/cuu/Units/binary.html

A binary megabyte (Mebibyte) is 2^20 bytes = 1,048,576 bytes

Hard drive manufacturers quote capacity based on decimal multiples - a megabyte is 1,000,000 bytes, etc.

The intermediate values eg a megabyte being 1000 KB (1,024,000 bytes) appear in some things like DOS disk utilities, where megabytes are calculated as decimal multiples of the 512 byte disk sector size (ie a megabyte is 2000 sectors).
