**Title:** Understanding MIPS Machine Language: Binary Code for Basic Instructions

---

**Introduction:**

In this section, we will explore how to translate MIPS assembly instructions into their corresponding machine language binary code. This process involves understanding the instruction format and encoding required for MIPS architecture.

**MIPS Instructions:**

- **Instruction 1: Load Word (lw)**
  ```
  lw $t0, 1200($t1)  # Temporary register $t0 gets A[300]
  ```

  - Operation: Load the word from memory addressed in $t1 offset by 1200 into register $t0.

- **Instruction 2: Add**
  ```
  add $t0, $s2, $t0  # Temporary register $t0 gets h+A[300]
  ```

  - Operation: Add the contents of register $s2 with $t0 and store the result back in $t0.

- **Instruction 3: Store Word (sw)**
  ```
  sw $t0, 1200($t1)  # Stores h+A[300] $t0 back into A[300]
  ```

  - Operation: Store the word from register $t0 into memory addressed in $t1 offset by 1200.

**Explanation:**

These MIPS instructions are used for basic operations involving memory and arithmetic:

1. **Load Word (lw):** This instruction loads data from a specified memory location into a register. The memory address is calculated by adding an offset to the base address in a register.

2. **Add:** This arithmetic operation adds the values from two registers and stores the result in a destination register.

3. **Store Word (sw):** This instruction stores data from a register into a specified memory location, using a similar address computation as the load word.

The comments in the code describe the purpose of each instruction in the context of manipulating data stored at memory location A[300].

**Conclusion:**

Understanding how to convert these instructions into binary code involves knowledge of the MIPS command formats, opcode assignments, and register encoding. Each step plays a crucial role in executing high-level programming logic at the hardware level.
