What is a hardware address? pg.94
MAC address is burned right into the network card of a PC.
How do you get someone’s MAC address if all you know is there name not the IP address?pg94
You use name resolution (hostname-to-IP-address resolution)
If two hosts are on the same LAN they don’t need DNS to broadcast, when asking information. T or F pg.94
True.
What does ARP stand for? pg95
Address Resolution Protocol.
_____ is a contention media-access method that allows all hosts on a network to share the same bandwidth of a link.pg 95
Ethernet. pg.95 It is popular because of its readily scalable–easy to integrate new technologies.
Ethernet uses both __ __ and __ __ specifications.pg95
Data Link, Physical layer
What is the Ethernet term for a network scenario where one device sends a packet out and forces every other device on that network to pay attention to it? pg95
Collision domain.
___ ___ is a situation where each device’s digital signals interfere with another on the wire and forces the devices to retransmit late.pg96
Collision event.
Collision events are typically found in what type of environment.pg96
Hub environment. pg96 Where each host segment connects to a hub that represents only one collision domain and one broadcast domain.
What is a broadcast domain? pg96
It refers to the set of all devices on a network segment that hear all the broadcasts sent on that segment.
What is a media access control method that helps devices share the bandwidth evenly without having two devices transmit at the same time on the network medium.pg96
(CSMA/CD) Carrier Sense Multiple Access with Collision Detection. pg96 It was created to overcome the problem of those collisions that occur when packets are transmitted simultaneously from different hosts.
