How did the widespread adoption of the OSI model change the development of network technologies?

he widespread adoption of the OSI model changes the development of network technologies in many ways. Most traditional communications media including telephone, music, film, and television are reshaped or redefined by the internet, giving birth to new services such as Voice over Internet Protocol (VoIP) and Internet Protocol Television (IPTV). Newspaper, book and other print publishing are adapting to Web site technology that have reshaped into blogging and web feeds. The Internet has enabled or accelerated new forms of human interactions through instant messaging, Internet forums, and social networking. Online shopping has boomed both for major retail outlets and traders. Business-to-business and financial services on the Internet affect supply chains across entire industries.

The early development of LANs, MANs, and WANs was confused in many ways. The early 1980s saw great increases in the number and sizes of networks. As companies realized that they could save money and gain productivity by adoption of the OSI model. The existence of the model makes it easier for networks to be analyzed, designed, built and rearranged, by allowing them to be considered as modular pieces that interact in predictable ways, rather than enormous, complex monoliths. Today's data communications environment differs from that of 20 years ago in that it reduces complexity, possess standardized interfaces, facilitates modular engineering, ensures interoperability between vendors, simplify teaching and learning.
