star topology needs correct answer: hub or switch hub correct answer: A device that uses its ports to connect devices (computers, printers, etc.) cal layer of the OSI model.It forwards data packets to connected devices switch correct answer: A device for making, breaking, or changing the connections in an electrical circuit. Is smart, faster and more efficient. Data link layer of the OSI model. It passes data based on the MAC address. Router correct answer: A type of computer that forwards data across a network. Works with an IP address. sits at the network layer of the OSI model Access Point correct answer: the computer or network device that serves as an interface between devices and the network.It provides connection to the wired LAN. mounts towards the ceiling and sits at the data link layer of the OSI model. protocol correct answer: A set of rules governing the exchange or transmission of data between devices. Topology correct answer: The physical and logical design of a computer network; examples include mesh, bus, ring and star; the physical layout of the network devices and the cabling, and how all the components communicate with each is the network architecture used to interconnect the networking equipment Bus Topology correct answer: A network layout in which there is one main trunk, or backbone, that all the various computers and network devices are connected to. enable coworkers to share resources with each other using a cable. the cable is terminated on each end. data packets travel using electrical signals on each end.It is slow and easy to set up. First come first serve. token ring topology correct answer: A type of LAN ring topology in which a frame containing a specific format; called the token; is passed from one station to the next around the ring. When a station receives the token; it is allowed to transmit. The station can send as many frames as desired until a predefined time limit is reached. When a station either has no more frames to send or reaches the time limit; it transmits the token. Token passing prevents data collisions that can occur when two computers begin transmitting at the same time. toking ring topology advantage correct answer: it is deterministic .This means that the networking devices gain control of the network at fixed time intervals Star Topology correct answer: A topology with one central node that has each computer or network device attached to the central node. All data first goes into the central node and then is sent out to its destination. (Think of it like a bic
