A device or computer that has an ;0 address is a host. Short Answer
15. ,hat is the central device used in wireless LANs! Answer: wireless access point %ifficulty: &asy 'ection (eference: ;dentifying Types of LANs &)planation: The wireless access point 9,A0" acts as the central connecting device for the network. Today such networks can consist of many types of devices other than traditional 0Bs including smart phones 0%As ta$let computers and microcomputers. 1. ,hat is the difference $etween a switch and a hu$! Answer: A hu$ allows only one device to communicate to another device at a time. ;f two devices try to communicate at the same time a collision will result. A switch allows multiple conversations to occur at the same time. ;n addition a switch also supports full8duple) which means that a computer or host can send and receive at the same time. %ifficulty:
