5.4 - Data Buses TQ Flashcards
Which of the following statement is 5/5
true for ARINC 629
multi transmitter, bi directional, less
number of wires, more data can be
sent, 120 user, full duplex
Which statement is true for Basic
Ethernet
it is faster than ARINC 429 and new
computers/systems can be electrically installed easily
What is the disadvantage of Basic ethernet
Adding more computers can increase the delay time
In basic ethernet system
Only one LRU can get the backbone at a time
Carrier Sense Means what?
LRU sense the carrier before transmitting, if no other LRU is transmitting at that time, then the LRU will transmit data
Basic eternet uses which technology?
Carrier Sense multiple Access with
Collision detection CSMA/CD
The sign status matrix (SSM) does what
Tells the signs of the data and validates the system
