There are a number of different web protocols. They help us in our day to day lives and we use them without even thinking sometimes. Over three years they have got better and better. They are very helpful in many different way from browsing the web on the move on you mobile to using a sat nav to find your way to places in a car. In this assignment I will be talking about the different types of web protocol that are about.
GPRS (General packet radio service)
This allows information to be sent and received across a mobile telephone network. Maximum speeds of up to 171.2 kilobits per second (kbps) are achievable with GPRS using all eight time slots at the same time. This is about three times as fast as the data transmission speeds possible over today's fixed telecommunications networks and ten times as fast as current Circuit Switched Data services on GSM networks. By allowing information to be transmitted more quickly, immediately and efficiently across the mobile network, GPRS may well be a relatively less costly mobile data service compared to SMS and Circuit Switched Data.
GPRS will fully enable the Internet applications you are used to on your desktop from web browsing to chat over the mobile network. Other new applications for GPRS also file transfer and home automation - the ability to remotely access and control in-house appliances and machines.
3G
( The third generation of wireless technologies). It comes with enhancements over previous wireless technologies, like high-speed transmission, advanced multimedia access and global roaming. 3G is mostly used with mobile phones and handsets as a means to connect the phone to the Internet or other IP networks in order to make voice and video calls, to download and upload data and to surf the net.
The advantages of using 3G are that you can browse the Internet on your mobile or portable device at a high speed and download music at high speed. Most 3G phones have a two cameras, this is so you can make video calls with other people.
3G is not that cheap but it's good for people that are on the move such as business people.
Sms
( Short Message Service). This is otherwise known as a text message. You can send a text message to someone on your phone to anyone anywhere around the world. You can even send one text to multiple contacts. They can also be sent from a home phone.
Sms is a simple way to send a short message to someone quickly. Every mobile phone has the capability to send an SMS message.
SMS doesn't just have to be used for a message to one person to another, you can have text alerts, whether this is to remind you of something you need to do or if its from a news company telling you what the latest news is or even the latest football scores! Text messaging can also be used to enter competitions that appear on TV.
MMS
(Multimedia Messaging Service) just like sms it’s a way of sending messages form one phone to the other. But mms can do more, it doesn't just have to be text it can include sound, video and pictures. You can also send an mms message to an email address!
I think that mms is good because you can sent pictures or videos to other peoples phones without them having to wait until they check their emails to receive it. But on the down side it costs a lot more than a usual text to send an mms, so I think I would prefer to do it by email
WAP
(wireless application protocol)
Is a type of Internet connection. It makes the web more accessible. For example wireless Internet, for laptops and mobile phones. It is based on Internet standards. (HTML, XML and TCP/IP). A few examples of WAP that are useful -
- Checking train table information
- Ticket purchase
- Flight check in
- Viewing traffic information
- Checking weather conditions
- Looking up stock values
- Looking up phone numbers
- Looking up addresses
- Looking up sport results
- checking emails
GSM
(Global System for Mobile communications)
This is a protocol which is very popular in many different parts of the world. GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot. It operates at either the 900 MHz or 1800 MHz frequency band.
