with incorporating a local area network (LAN) would allow a better line of communication between each employee, as well as able to obtain information more efficiently. Building an intranet system will support the organization in allowing employees to access information stored from a central depository such as a database server. Dirt Bikes’ can also implement a Voice over IP system. The first recommendation is for Dirt Bikes’ to introduce a local area network to allow all the computers to communicate

facilitates communication in the most efficient manner. In order to achieve the desired connectivity, an array of products and services will be necessary. Logical Network Design The network topology used for Acme’s WAN should be a star topology with each site having only a direct connection to headquarters; the benefit is that network administration is centralized. The engineering and sales offices will connect to headquarters over the public WAN through a VPN configured with L2TP and IPSec for

vendors sell many different types of physical interface cards, so the routers have the right physical connectors to connect to different types of networks. D. Routers discard old data-link headers and insert new data-link headers as part of their logic, which treats each interface’s lower-layer details as independent from each other. 4. An enterprise network has many routers that connect to both a LAN as well as the WAN. Which one of the following statements best describes how routers typically use

advancement of the Wireless Sensor Networks (WNSs). Their usage in various fields making them the most fast evolving technology. The wireless sensor network consist of a large number of sensor nodes, Sink and the Actuator. These sensor networks use broadcast communication paradigm but most of the networks depends on point-to-point communication. The sensor networks does not have a global identification because of large in number. The communication architecture of sensor networks has three phases 1. Sensor
