Types of Internet Access


Types of Internet Access

Dial-up
A dial-up modem converts digital signals from a computer to analogue signals that are then sent down the telephone line. A modem on the other end converts the analogue signal back to a digital signal the computer can understand.


 Broadband 
Cable broadband works on the same principles of ADSL broadband. The modem still receives data and signals from a wire and the connection is always on. However, instead of using copper wires, cable broadband uses fibre-optic materials.

 fixed broadband
ADSL broadband comes from your local telephone exchange, owned by BT, through a Fixed Line Access Network made out of copper wires. ... The lines in the street connect to the wiring inside your house and provide you with an internet and phone connection through the BT socket on the wall.

fixed wireless
With the growing infrastructure of the GSM wireless networks, fixed wireless has also become a viable solution for broadband access. Using the 3G speed and reliability, businesses and homes can use fixed-wireless antenna technology to access broadband Internet and Layer 2 networks using fixed wireless broadband.

 Satellite
Satellite internet equipment is made up of three main components: a geostationary satellite in space, a satellite dish mounted on your home and a modem that transmits internet signals from the dish to your computer. You obtain satellite internet through a satellite broadband provider.

Wireless hotspots
Put simply, a portable hotspot taps into 3G and/or 4G cellular networks, just like a smartphone does, and then wirelessly shares its data connection with other nearby (within 30 feet or so) Wi-Fi-enabled gadget—typically, between three and 8 or more at a time, depending on the device and the carrier.

 mobile phones 
Cell phones have an in-built antenna which is used to send packets of digital information back and forth with cell-phone towers via radio waves. Mobile phones connect to a cell tower in the area, and instead of connecting to another phone it connects to the Internet and can fetch or retrieve data.

How the world wide web was affected by the use of cross-platform and open source. The Growth of the World Wide Web In 1989 the world wide web was invented by Sir Tim Berners-Lee. He was trying to find a new way for scientists to easily share the data from their experiments.  Hypertext and the internet already existed at this point but no one had thought of a way to use the internet to link one document directly to another.  Tim suggested three main technologies that meant all computers could understand each other (HTML, URL and HTTP). All of these remain in use today.  He also made the world’s first web browser and web server. You can still see pages from the first web server online. How the world wide web was affected by the use of cross-platform The world wide web allowed it to be access by anything regardless of weather or not your computer is high end or not. But the world wide web isn't limited to one type of device, and is not developed by any one co...
