What is an example of an informational computer
Engine Indication and Crew Alerting System (EICAS)
What are the other two categories of PROM
Erasable Programmable Read Only Memory (EPROM)
Electrically Alterable Read Only Memory (EAROM)
Which memory type cannot usually be changed after manufacturer
ROM
What does EEC stand for
Electronic Engine Control
What is Interactive Computers
Can perform several different tasks
Display information to the operator
What is hardware
All other parts and devices to do with the digital data
What type of memory is RAM
Volatile memory, this means that unsaved data in RAM is lost when power is off
What is an informational computer
Collects data from various places, processes it and then formats it for display
What is an example of a reference computer
An inertial reference system
No input needed
What type of memory ROM
Non volatile.
Data stored in ROM are not lost at power lost
What does the data bus do?
Carries the data for the memory or I/O
The flight crew interfaces with the computer by the means of what
Control Display Unit (CDU)
What does EECM stand for
Electronic Engine Control Monitor (EECM)
What does the address bus do?
Specify the memory location or I/O port involved in a transfer
What does RAM stand for and what does it do?
Random Access Memory
Temporary storage until data is needed
What does I/O stand for and what does it do?
Input/Output device and it provides the interface between the microprocessor (cpu) and the outside world
What is software?
Programmes and instructions for CPU
What does EAROM do
Individual element of the memory can be changed without erasing all the data
What does ROM stand for and what does it do?
Read Only Memory
Contains the main program and tells the CPU what to do and when
What does EPROM do?
Erasing the existing program from the IC using UV light. Re program with 1’s and 0’s
What are the 3 types of buses
Data bus
Address bus
Control bus
What is an example of a interactive computer
Flight management computer (FMC)
What is a storage/Monitor Computer
Retain information provided to them by other systems and computers. Information stored may be used by other computers, flight crew…
What type of memory is used to store program steps and content values. It is used in situations where memory values do not change such as dedicated system
ROM
