What are programming paradigms?

• Different approaches to using a programming language to solve a problem
• Different forms of critical thinking
• Using one algorithm for different outcomes

Which two broad categories are programming paradigms split into?

• Imperative
• Declarative
• Event Driven
• Procedural
• Object Orientated

State the advantages of procedural programming

• Can be applied to a wide range of problems.
• Relatively easy to write and interpret.
• Reuse of code through inheritance
• Flexibility through polymorphism

State a use of declarative programming

• Expert Systems/ Knowledge-based Systems.
• Artificial Intelligence
• Sequential Execution
• Machine Architecture

Identify the main programming structures used in structured programming

• Sequence
• Selection
• Iteration
• Recursion
• Encapsulation

How does assembly language differ from machine code?

• Assembly language uses mnemonics rather than binary. One line in assembly language is equal to one line in machine code.
• Assembly language uses binary rather than mnemonics. One line in assembly language is equal to one line in machine code.
• Assembly language uses mnemonics rather than binary. One line in assembly language is equal to multiple lines in machine code.
• Assembly language uses mnemonics rather than binary. Multiple lines in assembly language is equal to one line in machine code.
• Assembly language uses binary rather than mnemonics. One line in assembly language is equal to multiple lines in machine code.

What is the function of the STA mnemonic?

• Storing the value in the Accumulator at the given memory address.
• Branches to a given address if the value in the Accumulator is positive. It is a conditional branch.
• it is meant to move data between registers and memory.
• The operands will usually name another register to use as the load address, plus perhaps a 3rd register to be added or scaled and added, or a constant, or all of them above.

What is the function of the BRP mnemonic?

• Branches to a given address if the value in the Accumulator is positive. It is a conditional branch.
• Storing the value in the Accumulator at the given memory address.
• it is meant to move data between registers and memory.
• The operands will usually name another register to use as the load address, plus perhaps a 3rd register to be added or scaled and added, or a constant, or all of them above.

State the function of the opcode and operand

• The opcode specifies the instruction to be performed and the addressing mode.
• The operand holds a value which is related to the data on which the instruction is to be performed.
• The opcerand specifies the instruction to be performed and the addressing mode.
• The opcode holds a value which is related to the data on which the instruction is to be performed.

Identify different addressing modes

• Immediate Addressing
• Direct Addressing
• Indirect Addressing
• Indexed Addressing
