protocols model

What was the main reason for the need for standardized networking protocols before the 1980s?

• Different vendors had their own protocols, making communication between different computers difficult.

• There were too many computers in the market.

• Networking was not considered important.

• Computers were not advanced enough to require networking.

What was the role of the US Department of Defense's DARPA program in networking?

• It was involved in the creation of the TCP/IP model.

• It developed the OSI model.

• It standardized networking protocols globally.
