The differences between MMS or emailing a picture (related to p4)

By sending a picture by text message charges a certain amount it depends on what network you are currently on. 

By emailing a picture is free no cost what so ever and no postage unless you put it up for the newspaper 

by MMS  when the person you send it to get the picture the picture will be blurry but not when you email the picture come clearly threw.

The speed by texts messages are very fast compared to the emailing 
emailing takes time to get to another person if another person lives in another country.

also the cost text messaging costs emailing does not cost much

 how do protocols keep your data safe? 

The way to keep your device safe is very easy you just need to follow the simple steps carefully what you do for example you should change your password regularly so people don't hack you if the have discovered your password you will still will still be safe as long as you do not put up true personal information. 

REMEMBER NOT TO GAVE YOU PASSWORD OUT TO ANYONE AS THEY CAN HACK YOU CAN CHANGE YOUR PASSWORD AND DETAILS. DON'T WRITE IT DOWN SOMEONE AS SOMEONE MIGHT FIND IT.

Encryption is another way of keeping your personal information safe. By encoding messages in this way it will stop people from eavesdropping or even hacking your information so they cannot read it. Only the people that you want to read your messages
