For example, a single computer can run web server and file server software at the same time to serve different data to clients making different kinds of requests.
As Consumer Reports noted, "We expect to not only see more cord-free earbuds at CES, but models that actually go beyond noise-canceling technology: The next generation of wireless earbuds will actually filter out ambient noise, and function a bit like a hearing aid to help you hear better in noisy environments." CES certainly offers a huge collection of some of the most groundbreaking, innovative devices around.
Examples of computer applications that use the client–server model are Email, network printing, and the World Wide Web.
The client-server characteristic describes the relationship of cooperating programs in an application.
Airpods are not hearing aids, but they do allow someone with a mild to moderate hearing loss to hear streaming sound more clearly.
These "hearables," which were also a feature at CES 2016, can act as fitness trackers, health monitors and so on.
