LDA addr and STA addr are Fortran language instructions stored in an external memory IC for a microprocessor.
Programs written for the 8080A must have slight modifications to run on the 8085A.
The software used to drive microprocessor-based systems is called:
When referring to instruction words, a mnemonic is:
The technique of assigning a memory address to each I/O device in the computer system is called:
A register in the microprocessor that keeps track of the answer or results of any arithmetic or logic operation is the:
Which of the following buses is primarily used to carry signals that direct other ICs to find out what type of operation is being performed?

What type of circuit is used at the interface point of an input port?
How many buses are connected as part of the 8085A microprocessor?
The ________ ensures that only one IC is active at a time to avoid a bus conflict caused by two ICs writing different data to the same bus.
Which of the following are the three basic sections of a microprocessor unit?
The register in the 8085A that is used to keep track of the memory address of the next op-code to be run in the program is the:
