WGU C172 Network and Security – Foundations- QUESTIONS WITH COMPLETE SOLUTIONS

protocol correct answer: The set of rules established for users to exchange information topology correct answer: The network architecture used to interconnect the networking equipment deterministic network correct answer: Each station connected to the network is ensured access for transmission of its messages at regular or fixed time intervals bus topology correct answer: The computers share the media (coaxial cable) for data transmission ThinNet correct answer: The coaxial cable used in a bus network. star topology correct answer: Twisted-pair cables connect the devices to a central hub or switch hub correct answer: A multiport repeater device used at the center of a star topology multiport repeater correct answer: The data it receives is broadcast and seen by all devices connected to its ports. A hub. broadcast correct answer: Transmission of data by a hub to all devices connected to its ports switch correct answer: Device used at the center of a star topology that forwards a frame it receives directly out the port associated with its destination address mesh topology correct answer: All networking devices are directly connected to each other, allows for full redundancy OSI model correct answer: The seven layers describing network functions Physical layer correct answer: Provides the electrical and mechanical connection to the network (cabling, NICs). 1st OSI layer Data link layer correct answer: Handles error recovery, flow control (synchronization), and sequencing (MAC, Ethernet). 2nd OSI layer Network layer correct answer: Accepts outgoing messages and combines messages or segments into packets, adding a header that includes routing information (IP, IPX). 3rd OSI layer Transport layer correct answer: Concerned with message integrity between source and destination (TCP, UDP). 4th OSI layer
