openings. Ping sweeps are often used in combination with Port scans‚ similar process. Ping sweeps are used to see what targets are available on the network. For instance‚ we may be on a 192.168.1.0 vlan with only a few computers. The router or DHCP server will assign each machine with its own IP address in order by request‚ by doing this the IP address can get out of order. A Ping sweep of the IP range 192.168.1.1 – 192.168.1.99 would show the computers are currently on the network. Hackers do

I. Computer Dynamics Computer Dynamics is a microcomputer software development company that has a 300-computer network. The company is located in three adjacent five-story buildings in an office park‚ with about 100 computers in each building. The current network is a poorly designed mix of Ethernet and token ring (Ethernet in two buildings and token ring in the other). The networks in all three buildings are heavily overloaded‚ and the company anticipates significant growth in network traffic.

Discuss Network Topology Network topology refers to the physical layout of a network. The chosen layout directly impacts how each node on a given network communicates with another. There are multiple types of topologies that can be used based on the need of the project. The ultimate goal is to provide multiple lines of data communication which will increase fault tolerance on the network and reduce or eliminate a complete disruption of service. A mesh topology offers the most effective fault
