Coursera Course 2 Week 1 UPDATED ACTUAL Questions
and CORRECT Answers
1. Duplex Communica- The concept that information can flow in both directions across the cable.
tion
2. Half-Duplex Communicate in only one direction at a time.
3. Ethernet Protocol of the data link layer used for transmitting data between devices
on a Local Area Network
4. CSMA/CD Short for carrier sense multiple access with collision detection. It is the
method for multiple hosts to communicate on a Ethernet.
5. Media Access Control On a Layer 2 switches are mapped to specific of the device attached
Address (MAC Address)
6. Collision Domain On an Ethernet network, a(n) is the portion of a network in which
collisions occur if two nodes transmit data at the same time.
7. Organizationally The first 24 bits of a MAC address (first three octets), assigned to the NIC
Unique Identifier (OUI) manufacturer by the IEEE.
8. Unicast If the least significant bit in the first octet of a destination address is set
to zero, it means that Ethernet frame is intended for only the destination
address.
This means it would be sent to all devices on the collision domain, but
only actually received and processed by the intended destination.
This is a transmission over the Ethernet Protocol
9. Ethernet Transmission 1. Unicast
Types 2. MultiCast
3. Broadcast
10. Multicast If the least significant bit in the first octet of a destination address
is set to one, it means you're dealing with a frame.
