Word Associations Flashcards
Various tech words and what I want to think about when I see these words.
Segment
Layer 4 TCP - The unit of data.
VLANs - Logical grouping of devices within the same broadcast domain.
Datagram
Layer 4 UDP - The unit of data.
Packet
Layer 3 - The unit of data.
Frame
Layer 2 - The unit of data.
Bit
Layer 1 - The unit of data.
Broadcast Domain
Layer 2 - All the devices that would receive a broadcast message. All devices within a single LAN or VLAN would be in the same broadcast domain.
Broadcast Domains are separated by routers.
Collision Domain
Layer 1/2 - Where data packets can collide with one another. A switch has each port as a separate collision domain (a hub would have all ports within the same collision domain).
Collision Domains are separated by switches.
H.323
The protocol used for VoIP and video conferencing.
