Today I want to explain you that "Are Cisco Packet tracer and GNS3 simulator or emulators?. What is the difference between simulators and emulators?."
In other field of world, simulators and emulators have same meaning.A simulator is a software that provide the environment to the user to do work which is not real.A famous example for a simulator is the flight simulator that simulates the functionality of an aircraft . It is help full in the development process.
A emulator is a hardware which provides the real environment and functionality of image operating system which work as a actual system.
Cisco Packet tracer is a simulator because it only provide environment to the user to do work which is not real.It has limited functionality and completely help full for CCNA level but not completely help full of CCNP level.Cisco Packet tracer commands does not support completely.There is weak point exist in Cisco Packet tracer.

GNS3 is a network emulator which provides the real environment and functionality of image operating system which work as actual system.Real operating systems run in to GNS3. A lot of RAM consume in GNS3. but it is completely help full at CCNP level.

ReplyDeletegood explication :-)
ReplyDeleteI would say that an emulator has the functionality of a real-world networking environment. GNS3 is an open source (vendor neutral) emulator and is extremely "raw." Images such as routers and PCs are not automatically included and have to be downloaded. The only advantage that it has over the simulator called Cisco Packet Tracer, is the fact that a virtual networking environment and a physical networking environment can be interconnected. Otherwise, I'm using Packet Tracer 99% of the time. I really don't care for the functionality of GNS3.
