How does PDUs pass down the stack?
- Data (Data Stream)
- Segment
- Packet
- Frame
- Bits (Bit Stream)
When it detects a problem it will broadcast it and will give way to the traffic and it will have flow control one at a time to avoid collision, but only happens on wireless networks
Carrier sense multiple access with collision
avoidance CSMA/CA (wireless)
A network protocol function that uniquely labels each transmitted segment of data
Sequencing
True or False:
When a message is sent, it must use a specific format or structure.
True
A type of protocol that is used for the automatic detection of devices or services.
Service Discovery
An internet standard that focused on long-term research related to internet and TCP/IP protocols.

It is a one to one communication
Unicast
A network protocol function that ensures data flows at an efficient rate
Flow Control
It is the left -most part of the address indicates the network group of which the IP address is a member. Each LAN or WAN will have the same network portion.
Network portion (IPv4) or Prefix (IPv6)
True or False:
All communications are governed by protocols.
True
Last in First Out
Stack
A type of protocol that enable two or more devices to communicate over one or more networks.
