Justify the protocol transmission type you used. Ensure you find positive and negative aspects for the protocol and suggest a second way you could have sent the contact.

positive;

the protocol transmission i used was Bluetooth when i sent a photo through Bluetooth to a friend. the positive aspects are that the other person got it for free, they did not have to pay for it which is good for them. also, it is very secure so no one can hack into it, you can create a password for it. you can switch Bluetooth on and off so no one can find you when its off and just switch it on when you wan to be found. bluetooth also does not drain your battery, which is a good thing because you can then do more.

negative; 
bluetooth can only be used in a certain distance which is bad because you have to be near the person if you wanted too send them a data file. bluetooth is also very slow so it will take a while to transmit your data across to others.


instead of bluetooh another way you can send yoru data is through email it is much faster and takes 2 seconds to attach a file. the file size is also bigger so you can see it clearer and better.
