Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks.The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
DevNet's Learning Labs provide individual labs, learning modules, and learning tracks for coders of all skill levels. Developers and students can learn coding basics. Network engineers can get more familiar with Software Defined Networking (SDN) and other networking-specific areas. Experienced coders can get more in-depth training on Cisco APIs.
In computer network research, network simulation is a technique whereby a software program replicates the behavior of a real network. This is achieved by calculating the interactions between the different network entities such as routers, switches, nodes, access points, links, etc. [1] Most simulators use discrete event simulation in which the modeling of systems in which state variables ...
Cisco Networking Academy or NetAcad is an online global educational program product of American Cisco Systems. It started in California in 1997. [1] [2] [3] [4]
An internetwork is the connection of multiple different types of computer networks to form a single computer network using higher-layer network protocols and connecting them together using routers. The Internet is the largest example of internetwork. It is a global system of interconnected governmental, academic, corporate, public, and private ...
A local area network (LAN) is a computer network that interconnects computers within a single physical location. It is the most common type of computer network, used in homes and buildings including offices or schools, [ 1 ] [ 2 ] [ 3 ] for sharing data and devices between each other, including Internet access .

Network emulation is the act of testing the behavior of a network (5G, wireless, MANETs, etc) in a lab. A personal computer or virtual machine runs software to perform the network emulation; a dedicated emulation device is sometimes used for link emulation. Networks introduce delay, errors, and drop packets.
