UNIT 14 D2

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.

• A protocol that I use is bluetooth, i use this to send stuff such as music; pictures, videos e.t.c 
• before using bluetooth you  would have to switch it on first.Whilst  bluetooth you would have to pair with other devices then search them in your previous bluetooth senders, when you have done pairing you have switch off your bluetooth
• Bluetooth is useful because you can send to any technical device and it has no limit.
• Negatives about bluetooth is that sometimes depending on what phone you have bluetooth doesn't send, such  phones are IPhones.
• Another negative about this protocol is that depending on the distance of the mobile device it would not send, if someone starts to get a distance from you and you are bluetoothing it would automatically stop.

• Another Protocol is BBM which stands for blackberry messenger. Using BBM you can be sending things to other blackberry's such as music, pictures; video's e.t.c. 
• The negatives about BBM it has a limit of Mega bites (MB) sometimes when sending things it will decline your request because of the MB limit.
• Another negative is that because of BBM it is only on Blackberry's and even with BBM you cannot send it on other devices except for Blackberry's.
• Even with the MB limit you can still send things and also messages.
