Task 2.5

a)      Satya and Simon can let their friend know what they are doing by text however when they text they have to send multiple different messages and forward multiple recipients which could cost a lot more money. They could also use a range of social networking sites (Facebook, twitter, MySpace) to write one status and let all their friends know what they are doing however this requires an internet connection and if through phone then coverage to a network. They could also use email but the same applies with a phone you need internet connection and or coverage from a mobile network.

b)      To take photos and send it to family/friends they would use either phone email or social networking, the advantage of using social networking is you only have to post it once and everyone you want to see will see it, disadvantage would be that other who you may not want to see it could see it and unless you spend time making it private which is effort. You can also use mobile phones but again the text cost is very expensive to send a picture unless you have a contract however this requires access to and 3g connection. With email it is the same point you must add multiple recipients and send to them individually which is slower.
