To day Lesson: Internet Connection

Summary





 







Wireless

Radio frequency bands are used in place of telephone or cable networks. One of the greatest advantages of wireless Internet connections is the “always-on” connection that can be accessed from any location that falls within network coverage. Wireless connections are made possible through the use of a modem, which picks up Internet signals and sends them to other devices.
Mobile
Many cell phone and smartphone providers offer voice plans with Internet access. Mobile Internet connections provide good speeds and allow you to access the Internet on the go.
Hotspots
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. Hotspots can be phone-based or free-standing, commercial or free to the public.
Dial-Up
Dial-up connections require users to link their phone line to a computer in order to access the Internet. This particular type of connection—also referred to as analog—does not permit users to make or receive phone calls through their home phone service while using the Internet.
Broadband
This high-speed Internet connection is provided through either cable or telephone companies. One of the fastest options available, broadband Internet uses multiple data channels to send large quantities of information
DSL
DSL, which stands for Digital Subscriber Line, uses existing 2-wire copper telephone line connected to one’s home so service is delivered at the same time as landline telephone service.
Cable Internet connection
Cable Internet connection is a form of broadband access. Through use of a cable modem, users can access the Internet over cable TV lines. Cable modems can provide extremely fast access to the Internet.
Satellite
In certain areas where broadband connection is not yet offered, a satellite Internet option may be available. Similar to wireless access, satellite connection utilizes a modem.
ISDN
ISDN (Integrated Services Digital Network) allows users to send data, voice and video content over digital telephone lines or standard telephone wires.

Follow these step-by-step instructions to connect to the internet
Step 1: Choose an internet service provider (ISP). This could be the company that provides your telephone line or it could be one of the many independent providers.
Step 2: Having chosen an ISP and signed the contract, you’ll have to wait a few days while your line is converted to broadband. During this time, you should receive a letter with your username and password and the hardware you’ll need: a small box called a 'router' and its attachments. You can see an example on the right.
Step 3: Once you’re told that your broadband is active, you can set up your router.
Step 4: When you get the router, you should also receive a CD. Once you’ve set up the router, all you need to do is put the CD into your computer and follow the step-by-step instructions. If you don’t want to do this yourself, some companies offer a home installation service and, for an extra cost, will send an engineer to set up your broadband connection for you.
