task 3 m2 unit 14


M2
What are the main differences when comparing the two technologies described for P4?  Think about the speed of the transmission, costs and coverage.

The main differences are with a mobile is you cannot connect if you were in the middle of a countryside. You could send a picture message through 3g but it will cost and it isn’t that big, it comes out small. The best method is too send it through email and making your phone the hotspot because sending it through email does not cost and it comes out bigger than your phone. The final way of doing it is uploading it to your computer then transferring it through email.

m2- Unit 14

The main difference from sending something from a location off his smart phone and from his home using broadband would be that sending something from his own home would not cost and it would send faster but if he sent something using his phone it could cost. it depends on what technology your using and depends on how fast your phone is too send something too someone, 3g or wireless connection is. The file sizes matter because if your sending a picture it has to be clear instead of through picture message with a small size where as if you send it through email it is a big size and is much clear too see.
