As you are aware the World Wide Web is a collection of electronic documents that are linked together like a spider web. As you explore this Network you will find lots of information on wheelchairs. In fact we estimate that you will locate no less than 10,000 documents or web sites on wheelchairs.
The wheelchairs websites or pages are located on computers which are called servers. Some servers are exclusively dedicated to wheelchairs.
If a wheelchairs supplier is sufficiently committed to their marketing that they develop their own server technology to service wheelchairs customers then you can be reasonably confident that they are there for the long haul.
