Describe a satellite network system.
What will be an ideal response?
The Hughes Corporation offers a unique solution to low-speed Internet connections. For a few hundred dollars, you can buy their HughesNet Internet satellite networking system. Internet data comes to your PC via satellite at speeds between 500Kbps to 800Kbps. Upload speeds are considerably slower at approximately 128Kbps, but well within an acceptable range. This is an ideal situation for browsing, when you need to receive information fast (if a Web page contains many images) but only send information out (clicking on a new URL to load a new page) occasionally. A lower-speed connection for transmitted packets is generally acceptable, unless you are uploading large files to an FTP site or sending e-mail with large attachments. If there is no cable where you live or work (for a cable modem connection), HughesNet or another Internet satellite provider may be the answer for you.
