Unit 14 Task 2

P3

Mobile phones have protocols used to connect to other electric devices like laptops through the internet.

Some exsamples could be:-

Wireless application Protocol (WAP)
It is a technical standard to accsesing information on the internet wireless. WAP is a web browser. This is needed to accses the internet and things like Facebook or the news. It is a suit that allows other protocol equipment like GSM to work on the mobile phones.

Bluetooth
Its a open wireless technology standard for exchanging data over short distances. This can be done using short waves lenght from an ISM band. This can create personal are networks (PAN). Its another altinative to data cables and can prevent synchronization and it can be used on any devices.

Short message services (SMS)
This is short communication messeging between electric devices.

Wifi
It is a famouse technology that allows electrical devices to exchange data wirelessly over a mobile or computer network wich comes whith highspeed broadband.

GSM
One of the most sucssesful cellular systems, it uses narrow bands like TDMA wich allows 8 stimutainiouse calls on the same radio frequency.

Infrared
Protocols for wireless infrared communication, the reason it is used beacuse it emits its own wave from one device to another transfering information between devices. Infrared could be found in devices like a USB stick.

Then again there are also protocols used when using a PC or a laptop for exsample:-

HTTP
This is used to show how messages are formated and transmitted.

NTP
Internet standar protocol that assures scynchzorisation to the millisecond of computer clocktime in a network of computers.

M1

There is one main protocol that is used in electronic devices that keep data save and that would be an IP address. An ip addresss pin points wireless networks in an area, wich gets send to an authority to govern internet activity. They consist of 4 numbers and they are all unique wich makes it impossible for someone to use another one.

If you were to use sky broadband and their wiki only you can use it beacuse you know the password wich comes at the back of the sky box, and people who dont know the password cant.

Stateless wich allows sequence of internet accses, the programs keep track of accses this is another safemode.

There are also encypted codes wich is when infromation in encoded in such a way that evedroppers and hackers cant accses it but authorities can.

 Encryption is the process of encoding messages and information in such a way that eavesdroppers or hackers cannot read it, but that authorized parties can. Like the person who enables it or put it there on the first place. In an encryption scheme, the message or information referred as plain text is encrypted using an encryption algorithm, turning it into an unreadable ciphertext.
