They enable workers to collaborate upon documents in real-time with coworkers within city, region, or region. They permit schools to teleconference with students in Tokyo or perhaps Florida without spending massive amounts of money in long-distance phone calls. And they enable us to stream videos, play free games, and use a variety of different applications that would be impossible or not practical with a lesser amount of advanced technology.
Systems are built with two standard components: equipment or endpoints, and links that connect them. Endpoints are typically computer systems, printers, and wireless routers. They exchange their views through a pair of protocols, guidelines, and methods that influence how information is directed between them. Networks also use redirecting devices just like switches and routers, which hook up local or metropolitan sites to one another. They can also connect regional or national communications systems to global ones including the Internet.
