There are exist several types to connect to the internet. Following are these Internet Connection Types available:
- Dial-up Connection
- Cable TV Internet connections
- Satellite Internet connections
- Wireless Internet Connections
Dial-up connection uses telephone line to connect PC to the internet. It requires a modem to setup dial-up connection. This modem works as an interface between PC and the telephone line. Modem converted digital signal to analog and again other modem converted analog signal to digital signal.
Dial-up is also a communication program that instructs the modem to make a call to specific number provided by an ISP.
Dial-up connection uses either of the following protocols:
- Serial Line Internet Protocol (SLIP)
- Point to Point Protocol (PPP)
ISDN is acronym of Integrated Services Digital Network. It establishes the connection using the phone lines which carry digital signals instead of analog signals.
There are two techniques to deliver ISDN services:
- Basic Rate Interface (BRI)
- Primary Rate Interface (PRI)
- The BRI ISDN consists of three distinct channels on a single ISDN line: t1o 64kbps B (Bearer) channel and one 16kbps D (Delta or Data) channels.
- The PRI ISDN consists of 23 B channels and one D channels with both have operating capacity of 64kbps individually making a total transmission rate of 1.54Mbps.
DSL is acronym of Digital Subscriber Line. It is a form of broadband connection as it provides connection over ordinary telephone lines.
Following are the several versions of DSL technique available today:
- Asymmetric DSL (ADSL)
- Symmetric DSL (SDSL)
- High bit-rate DSL (HDSL)
- Rate adaptive DSL (RDSL)
- Very high bit-rate DSL (VDSL)
- ISDN DSL (IDSL)
All of the above mentioned technologies differ in their upload and download speed, bit transfer rate and level of service.
4.Cable TV Internet Connection
Cable TV Internet connection is provided through Cable TV lines. It uses coaxial cable which is capable of transferring data at much higher speed than common telephone line.
- A cable modem is used to access this service, provided by the cable operator.
- The Cable modem comprises of two connections: one for internet service and other for Cable TV signals.
- Since Cable TV internet connections share a set amount of bandwidth with a group of customers, therefore, data transfer rate also depends on number of customers using the internet at the same time.
5.Satellite Internet Connection
Satellite Internet connection offers high speed connection to the internet. There are two types of satellite internet connection: one way connection or two way connection.
In one way connection, we can only download data but if we want to upload, we need a dialup access through ISP over telephone line.
In two way connection, we can download and upload the data by the satellite. It does not require any dialup connection.

6.Wireless Internet Connection
Wireless Internet Connection makes use of radio frequency bands to connect to the internet and offers a very high speed. The wireless internet connection can be obtained by either WiFi or Bluetooth.
- Wi Fi wireless technology is based on IEEE 802.11 standards which allow the electronic device to connect to the internet.
- Bluetooth wireless technology makes use of short-wavelength radio waves and helps to create personal area network (PAN).
- Many cell phone and smartphone providers offer voice plans with Internet access. Mobile Internet Connection Types provide good speeds and allow you to access the Internet on the go.
Hotspots are sites that offer Internet access over a wireless local area network (WLAN) by way of a router that then connects to an Internet service provider. Hotspots utilize Wi-Fi technology, which allows electronic devices to connect to the Internet or exchange data wirelessly through radio waves.
