| major internet communication methods. | | | | Dial up communication is a type of internet access |
| DSL | | | | that works on the regular telephone lines. The |
| Digital Subscribers Lines is an advanced technology | | | | computer is granted internet access by connecting |

| ADSL | | | | and external modem. |
| ADSL (Asynchronous Digital Subscribers Lines) is a | | | | GPRS |
| high speed internet connection that is used to send | | | | GPRS General Packet Radio Service is a series of |
| and receive data at very high speed over the | | | | functionalities that allow mobile data streaming and |
| conventional telephone lines. ADSL supports data rate | | | | transfer to users of Global System. GPRS also called |
| of 1.5 MBPS to 9 MBPS when receiving data | | | | as 2.5 G. GPRS allows multiple users to share |
| (downstream) and 16 to 440 KBPS when sending | | | | communication channel. GPRS facilitates the |
| data over internet (upstream) | | | | functionalities of web browsing, SMS, multimedia |
