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.

Who were the two scientists involved in the creation of the Transmission Control Protocol (TCP)?

• Vint Cerf and Bob Khan

• Tim Berners-Lee and Steve Jobs

• Bill Gates and Paul Allen

• Larry Page and Sergey Brin

In what year was the OSI model document published by the International Standardization Organization (ISO)?

• 1984

• 1978

• 1990

• 1980

Which model became the most used networking model by the end of the 1990s?

• TCP/IP model

• OSI model

• DEC model

• IBM model

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.

• It created the first computer network.

• today

• Today, network engineers still use the OSI model as a reference, but in practice the TCP/IP model is used.

• 1983

• the use of the OSI model started declining and the TCP/IP model became the most used one

• essential

• The OSI model consists of seven layers, each with its own function.

• seven

• Both models are essential for understanding network communication.

• four

• TCP/IP is a more simplified model with four layers.
