Assembly Language

What are instruction sets?

• Codes used for communication between processors
• Instructions recognized and processed by a processor
• Algorithms for high-level programming
• Data stored in memory locations

Why do instruction sets differ?

• They are specific to the processor
• They facilitate communication between different devices
• They enhance the speed of program execution
• They standardize programming languages

What is Assembly Language?

• High-level code similar to Python
• Low-level code using mnemonics converted by an assembler
• Machine code for communication protocols
• Intermediate code for virtual machines

Which statement best describes assembly code?

• It is as complex as machine code
• It is a midpoint between machine code and high-level languages
• It is easily understandable by non-programmers
• It requires an interpreter to execute

What is the primary purpose of assembly language?

• To make programming faster and easier
• To provide a human-readable representation of machine code
• To facilitate internet communication
• To automate repetitive tasks

What are the basic commands in assembly language used for?

• Mathematical calculations
• Input/output operations and data manipulation
• Graphics rendering
• Network communication

What does the command "LDA" do?

• Load the contents of the ACC onto the given address
• Load the contents of the given address onto the ACC
• Load the ACC with a constant value
• Load the ACC with data from an external device

What does the command "STA" do?

• Store the contents of the ACC to the given address
• Store the contents of the given address to the ACC
• Subtract the ACC from the given address
• Transfer data from one memory location to another

What does the command "ADD" do?

• Subtract the contents of the given address from the ACC
• Add the contents of the given address onto the ACC
• Multiply the contents of the given address with the ACC
• Divide the ACC by the given address

What does the command "SUB" do?

• Add the contents of the given address onto the ACC
• Subtract the contents of the given address from the ACC
• Copy the contents of the ACC to the given address
• Reset the ACC to zero
