Discussion :: Networking Basics - Networking Basics (Q.No.27)

27. 

What is the main reason the OSI model was created?

[A]. To create a layered model larger than the DoD model.
[B]. So application developers can change only one layer's protocols at a time.
[C]. So different networks could communicate.
[D]. So Cisco could use the model.

Answer: Option C

Explanation:

The primary reason the OSI model was created was so that different networks could inter-operate.

When networks first came into being, computers could typically communicate only with computers from the same manufacturer. For example, companies ran either a complete DECnet solution or an IBM solution—not both together. In the late 1970s, the
Open Systems Interconnection (OSI) reference model was created by the International Organization for Standardization (ISO) to break this barrier.

The OSI model was meant to help vendors create interoperable network devices and software in the form of protocols so that different vendor networks could work with each other.

The OSI model is the primary architectural model for networks. It describes how data and network information are communicated from an application on one computer through the network media to an application on another computer. The OSI reference model breaks this approach into layers.

OSI is the Open System interconnect. It is basically created where the different layers of network layers can communicate.
