INTERNET CONNECTION SPEEDS

Below are several ways that determine your internet speeds. Most personal computers bought today come with an internal standard V.90 Dial Up 56K analog Modem.

Any other connection which provides more speed requires additional hardware and software installation. Depending on which Internet Service Provider you use, determines whether you have to do the installation or someone comes to your house to do it.

Usually you pay much more for the higher connection speeds although prices are beginning to be more reasonable. Again I cannot stress enough to do your homework and research with what you are purchasing, and who will install it and set it up, and also the support available to you if the equipment should malfunction, or software doesn't work properly.

DIAL UP MODEMS

A dial up base band modem is a device that enables a computer to transmit data over telephone lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A analog modem converts between these two forms.

The internal standard V.90 Dial Up 56k analog modem transmits 56 Kbps (kilobits per second). This is the fastest internal dialup speed available today.

The older modems have connection speeds of 33.6 Kbps which is moderately fast, 28.8 Kbps which was the standard speed in the mid-1990's, and 14.4 Kbps which is very slow and does not support streaming audio and video.

ISDN MODEMS

Abbreviation of integrated services digital network, an international communications standard for sending voice, video, and data over digital telephone lines or normal telephone wires. ISDN supports data transfer rates of 64 Kbps (64,000 bits per second). Most ISDN lines offered by telephone companies give you two lines at once, called B channels. You can use one line for voice and the other for data, or you can use both lines for data to give you data rates of 128 Kbps, almost three times the data rate provided by today's fastest modems.

The original version of ISDN employs baseband transmission. Another version, called B-ISDN, uses broadband transmission and is able to support transmission rates of 1.5 Mbps. B-ISDN requires fiber optic cables and is not widely available.

DSL MODEMS

A direct broadband connection method is DSL (Digital Subscriber Line), which uses digital phone lines and a DSL Modem. You must check whether your local phone company supports DSL, and if you live close enough to a DSL Server. You must also have a NIC (Network interface card)inside of your computer.

DSL modems are usually limited to 10 Mbps because of that is the limit a NIC card can handle. Speeds range from 512 Kbps to 10 Mbps, and your download and upload speeds usually differ depending on the package you purchase.

DSL may eventually replace ISDN and DSL competes directly with cable modems.

Speed is also affected by how close you are to the physical location of the DSL Server.

CABLE MODEMS

You can also create a direct broadband connection to the Internet by using a cable modem provided that your cable TV company has prepared your location for the technology. Cable modems access the Internet through cable TV lines.

Cable modems are connected to a NIC card that you again must have inside of your PC, and again the internet speed is limited to 10 Mbps due to the limitations of the NIC card. Speeds also range from 512 Kbps to 10 Mbps, and again usually the download speed is faster than the upload speeds, depending on the package you purchase.

Speed is also affected by how many users share the same cable lines.

SATELLITE CONNECTIONS

The satellite connection is comprised of both indoor and outdoor equipment. Outside, there is an antenna and transmit-and-receive electronics, integrated into a small, unobtrusive dish. This equipment connects by coaxial cable to the Indoor Receive Unit (IRU) and the Indoor Transmit Unit (ITU), which connect to your computer through a simple USB connector.

Speed is advertised as 768 Kbit downlink / 128Kbit uplink speed but this is the maximum. Speed is affected by how you position your satellite dish towards the south where the most of the satellites are located.

This is an option for those people where DSL or Cable broadband is not available in their location. Of course this also seems the most costly way to connect to the Internet
