There is still some minority of people that have not yet owned a PC despite the spread of the use of computer. Some of them view a PC as a device that is too complicated for them to handle while some cannot afford to have one. Some of these people like e-mailing and surfing the internet most of their times without the complications that they have to know about a PC. Over the past few years, manufacturers have developed several products specifically for such people.
People that have been using the computer quite for some times and have been browsing would remember their first devices to access the internet. The first device is probably an external Modem. You had to enter the password and username to be connected to the internet, and a telephone line was used in your PC to get your connections. The speed of the internet was probably 56 kbps and this depended on the quality of your modem. After this technology, their came modems that were internally fixed to your computer. This modems did not increase the speed of your internet, they just saved space.
ISDN modems then came which had a speed of up to 128 Kbps. It allowed two-way images, data and voice by using 2 independent channels. At the same time their came ADSL that is Asynchronous digital subscriber line. It became popular more than the ISDN among access internet devices. Compared to the ISDN, the speed was a bit higher of about 256, 512 kbps and 1 and 2 mbps. You required a telephone line for you to be able to connect.
With such great speeds, high speed internet devices started to immerge. Companies started developing Broadband devices. Broadband can actually be defined as having download speed of at least 256 kbps or another company known as federal communication commission in the United States defines broadband as having data transmission speed of 768 kbps or more. The trend of high speed internet devices continued to grow as the market place continued to look for faster services.
Wireless technology like Wi-Max and Wi-Fi were riding the ADSL wave, this technology was greatly picking up in homes. This type of wireless technology lets a person use a broadband connection in many computers, without having the computers being physically connected to the ADSL modem. This made ADSL modems more acceptable in offices and homes today.
In the current market we also have high speed internet devices that can be connected to USB ports in your computer. The first technology on this had a speed of around 144 kbps, but this speeds increased with the current USB modems that we are currently using which have a speed up to 3mbps. Another important device that I have failed to mention is the cable modems. This kind of device uses a cable TV connection to give you access to the internet. By using a cable modem, you are guaranteed of receiving speeds over 2mbps or poor speeds and this will totally depend on the number of subscribers using this kind of technology to get access to the internet at some point in time.
