What is an advantage of using DHCP in a network environment? A. More different administration on the network B. Static IP addressing C. Can send an operating system for the PC to boot from D. Assigns IP address to hosts

C. Hub

What is device that connects segments of a network together but is nothing more than a glorified repeaters that are incapable of recognizing frames and data structures? A. Switch B. Router C. Hub D. Bridge
