- BAnalogue architecture used buses
- CAnalogue architecture units where hardwired
- DAll of the above
4A data bus is..
- AA subsystem that interconnects devices
- BA subsystem that needs algorithmic rules and protocols
- CCould be compared to a human nervous system
- DAll of the above
5Data buses could be classified as…
- ASerial or parallel
- BPoli and mono source
- CPrecedent and primary
- DPrimary and secondary
6Possible number of sources regarding buses are
- ASingle source (point to point)
- BSingle source (full duplex
- CMultiple source (half duplex)
- DNone of the above
7Select the correct anwer
- ACommunication protocols where only part of analogue architectures and no longer play a role regarding data buses
- BBus Architecture describes how the various system elements are interconnected and organized
- CLRU stands for Liquid Ram Units
- DA CPU is usually not part of the elements that comprise a bus data system
8Simple bus principles can be
- ASynchronous or asynchronous
- BA limitations is that data can only be exchanged between two devices
- CBoth are correct
- DNone of the above are correct
9About type of buses (choose the correct answer):
- AThe 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.
- BThe 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.
- CThe strong points of the MIL-STD-1553B are its reliability and sturdiness but it is not well established yet.
- DAll previous answers are correct.
10BUS (select the correct answer):
- A1. Is an electrical system which transports the energy from the electrical pumps to the electrical driven systems as informatic data.
- B2. Is a subsystem that permits interconnection and data exchange between the devices in a complex system.
- C3. Its basic components are wires, Information Packing Equipment and rules (algorithms and data format).
- D4. Can be classified as serial (several bits at a time) or parallel (most typical in aircrafts due to length and weight) .
11About fibre channel buses topologies
- A1) Arbitred loop 2) Point to point communication 3) Hubbed loop 4) Switched fabric
- B1) Switched fabric 2) Hubbed loop 3) Arbitred loop 4) Point to point communication
- C1) Arbitred loop 2) Point to point communication 3) Switched fabric 4) Hubbed loop
- D1) Point to point communication 2) Arbitred loop 3) Hubbed loop 4) Switched fabric
12Types of avionics architecture:
- A1) Distributed Analogue 2) Distributed Digital 3) Federal digital 4) Integrated Modular
- B1) Federal Digital 2) Integrated Modular 3) Distributed digital 4) Distributed Analogue
- C1) Distributed Digital 2) Integrated Modular 3) Federal digital 4) Distributed Analogue
- D1) Distributed Digital 2) Distributed Analogue 3) Federal digital 4) Integrated Modular
13The MIL-STD-1553B is an example of:
- AFederated digital architecture
- BDistributed analogue architecture
- CIntegrated modular architecture
- DDistributed digital architecture
14It is an element of the data buses:
- AA. LRUs (Line Replaceable Units) or Bus Users
- BB. Bus Stop / Bus coupler
- CC. A and B are correct
- DD. A and B are false
15The type of BUS can be classified by the:
- AA. Number of bits at a time (serial or parallel)
- BB. Number of sources and sinks (single surce – single sink, single source – multiple sink or multiple source – multiple sink)
- CC. Number of wires depending on the same Information Packing Equipment (single or dual
- DD. A and B are correct
16About JIAWG (Joint Integrated Avionics Working Group:
- AA. Is a development of modular integrated architecture implemented in the F22
- BB. Does not have data buses for cabinet interfaces
- CC. Has Common Integrated Processor (CIP)
- DD. A and C are correct
