Cisco Certified Network Associate certification has become must for anybody who wishes to start  a career in networking. This certification validates that you have the ability to install,configure and troubleshoot a network. You need  lot of practice for achieving success in this exam. Apart from the labs where you are getting trained for CCNA what if you had a chance to practice at home. Or what if you want to self learn for CCNA? Well for both of the questions above, Cisco Packet Tracer is the perfect answer. To quote from Cisco’s official website,Packet tracer is

“a powerful network simulation program that allows students to experiment with network behavior and ask “what if” questions.”

It further says,

“The simulation-based learning environment helps students develop 21st century skills such as decision making, creative and critical thinking, and problem solving. Packet Tracer complements the Networking Academy curricula, allowing instructors to easily teach and demonstrate complex technical concepts and networking systems design.”

Nothing could have defined that better. This software is available for free from Cisco’s website provided you are a registered Networking Academy student, alumni, instructor, or administrator. Even if you are not one among the above you could still get hold of this software,just google it.
