A computer network is a digital telecommunications network that allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections between nodes. These data links are established over cable media such as wires or optic cables, or wireless media such as WiFi.

Computer networking is an interdisciplinary field of computer science and engineering that deals with the design and implementation of computer networks. Networks range in size from a local area network (LAN) to a wide area network (WAN).

In the early days of computing, each time a new application was developed it had to be implemented on a new hardware platform and connected to the existing network. This was a time-consuming and expensive process.

With the advent of network analysis, it became possible to study the structure and behavior of existing networks in order to design more efficient and effective networks. Network analysis is a powerful tool that can be used to improve the performance of computer networks.

Network analysis can be used to determine the best location for new nodes in a network, the best routing paths between nodes, and the best way to allocate resources to nodes. Network analysis can also be used to identify bottlenecks in a network and to find ways to improve network performance.

Network analysis is a complex process, and there are a variety of methods that can be used to perform a network analysis. The most common method is to use network simulation software to create a model of the network.

Network simulation software allows the user to input data about the network, such as the number of nodes, the connections between nodes, and the resources that are available to each node. The software then simulates the behavior of the network, and the results of the simulation can be used to determine the best way to design the network.

Another common method of network analysis is to use network monitoring tools to collect data about the traffic on a network. This data can be used to identify bottlenecks and to find ways to improve network performance.
