In what ways has computer technology changed in your own lifetime?

The first time i used a computer in school i was 6 years old , and they were really slow and also the monitors were very thick , now the computers i have seen and also have worked with have the monitors very thin. Another thing that has changed is that the computers are actually much faster then when i used the first computers in my first grade class. Also when i would have to trasfer something to my teacher i would either have to send him an e-mail just like now but it would take like , 2 to 3 hours to upload the attachment into the e-mail and also now we use USB's to transfer our files from our own computer to another one but before we had a USB everyone would use floppys and the bad thing about that was that it would not store that much information as a USB and it would also take very long to upload aswell. Well my gradma told me that before she knew anything about a computer she would have to work very hard to find her answers now hse says that i have it easy that i don't have to do much work to find answer to my answers just "google" it . My gradma also says that she likes it to because she also uses it for "googling" things aswell
