D2 - UNIT 14

You can use a number of protocol transmission which include...

1. Email
2. Text Messages

Email - 

The good things about this protocol transmission is you can send things from all over the world and it the matter of seconds. However the bad things about email protocol transmission is sometimes the file might not open or it wont transfer all the information depending where you are.Also if you want to send alot of pictures you have to do it in separate emails which could cause some problems

Text Messages -

Text Messages is also a good protocol because its a easier way and it is very fast but the disadvantages is sometimes depending on what you are sending it may cost your more and if you don't know you could get carried away and your phone bill will be alot higher.

                                                                                                                                                                                                                                                                                                                                                                                                                          

M1 UNIT 14

M1
How do protocols and devices keep data safe?

To keep your devices safe you must set a password which only you will remember.Also you must change it on a regular bases so you have no risk of someone hacking you.

Furthermore you should always log out! Even if it is email or Facebook you must because the person using the computer/laptop after could access your messages because you are already logged in.

With WiFi you have to but a password/code so someone can not access it. However if you don't have a password its so much easier for someone to use your WiFi without you realising.
