Mobile and broadband subscribers versus installed base of laptops
In the past few years many TV shows and movies have suddenly been made available over the Internet.
It has driven more types of devices to be connected to networks, which in turn will increase the business value of a network to its nominal owners.

What is a social network? A human empowered network.
A platform specifically focused on the building and verifying of social networks for whatever purpose.
A platform where people from all walks of life come together to express themselves by means of sharing videos, music, pictures, content
It provides the ability to collaborate using peer-to-peer applications and services.
![Page 15: Technologies For Home Networking SUDHIR DIXIT / RAMJEE PRASAD](https://reader035.vdocuments.mx/reader035/viewer/2022062308/56649e365503460f94b26627/html5/thumbnails/15.jpg)
1.3.1 Business Applications Businesses are beginning to use social
networks as a means to connect employees and to help employees build profiles.
A network that connects businesses by industry, functions, geography , and areas of interest. Networks are usually free for businesses or at a low cost.
These networks act as a customer relationship management tool for companies selling products and services.

1.12 VISION OF THE FUTURE 1. It is logical to assume that all devices will
eventually be networked, but it will most probably start with devices that either are already intelligent (computers) or are very important to us (e.g., television, phone, and music system).
2. A possible way for the network to maximize its value is through server-to-server and peer-to-peer networking.
3.Devices, systems, services, and applications capabilities are defined by software.
