The methods mobile devices communicate are called protocols, you need to identify and describe all the protocols used by an up-to-date mobile phone and a laptop, giving examples of the file types you would send over these protocols.

• WiFi - WiFi is a type of protocol; it is wireless connection to internet, worked better in a local area than a far distance. This can be used to contact people using interractive internet such as facebook, twitter e.t.c , this is very useful but the negatives are that sometimes you will need a password to use someones or a public places WiFi, which in public area's you cant ger access of but in homes WiFi passwords are easily confused.
• 3G - 3G is a type of protocol, it is used for internet acess inside or outside the house, different to Wi-Fi; 3G offers better and more serviceoptions to its users, including mobile braod band. Also offers more fliexibility and service by making it more efficiant osed of moblie bandwidth than its predecessor 2G. Although faster and newer 4G tecnology is now available, 3G still remains the UK's dominant mobile broadband technolgy. The negatives about 3G is that it is only on mobiles that are on contract  but you cn get them on IPad's.
• sms - SMS is another protocol, it is used for mobiles to text other mobiles, you can receive and deliver messages from other people with mobles. The negatives about sms is that with no network you can type your message but it wont send, also you have to pay for sms it doesnt come cheap.
• Bluetooth - Bluetooth is also another type of protocol, it is used to send data to other devises such as song, video's; pictures .e.t.c bluetoth send to all sorts of devices if the bluetooth is connected. The negatives about bluetooth is that bluetooth only send from  a particular distance onces the devices are far from each other they will stop sending, also on some devices bluetooth doesn't work but that very rare.
