Multiple source (half duplex)
None of the above
Questão 7
Questão
Select the correct anwer
Responda
Communication protocols where only part of analogue architectures and no longer play a role regarding data buses
Bus Architecture describes how the various system elements are interconnected and organized
LRU stands for Liquid Ram Units
A CPU is usually not part of the elements that comprise a bus data system
Questão 8
Questão
Simple bus principles can be
Responda
Synchronous or asynchronous
A limitations is that data can only be exchanged between two devices
Both are correct
None of the above are correct
Questão 9
Questão
About type of buses (choose the correct answer):
Responda
The ARINC (Aeronautical Radio INCorporation) is widely used in civil aircraft and supports multiple-redundant operation with dual-redundant operation wich allows physical separation of data buses.
The MIL-STD-1553B is widely used in military aircraft and it is a command-response system in which transmissions are conducted under control of a single bus controller at any one time.
The strong points of the MIL-STD-1553B are its reliability and sturdiness but it is not well established yet.
All previous answers are correct.
Questão 10
Questão
BUS (select the correct answer):
Responda
1. Is an electrical system which transports the energy from the electrical pumps to the electrical driven systems as informatic data.
2. Is a subsystem that permits interconnection and data exchange between the devices in a complex system.
3. Its basic components are wires, Information Packing Equipment and rules (algorithms and data format).
4. Can be classified as serial (several bits at a time) or parallel (most typical in aircrafts due to length and weight) .
