Introduction

Assignment: Gain skills required for the practical portion of the CCENT certification: This particular lab does not require Cisco hardware to complete.

Conditions: You will find that the lab is most effective if you use it as a guide and work out your calculations on a separate sheet of paper.

Check Results: Since the labs already have built-in verification steps, baseline configurations are found here for reference.

Task 1 - Converting Decimal to Binary and Binary to Decimal

Step 1: Convert 146 into binary. Action:

Result: In the example of converting 48 to binary, start with the 128 column. Ask yourself, “Would 128 fit into 48?” It’s too large, so the answer is no, and a 0 is placed in that column. Next column, “Would 64 fit into 48?” Again, no, so a 0 goes in that column. Next, “Would 32 fit into 48?” Yes. Place a 1 in this column and subtract 32 from 48, leaving 16. “Would 16 fit into 16?” Yes. Place a 1 in this column and subtract 16, leaving 0. “Would 8 fit into 0?” No. So, a 0 goes in that column. The same applies for 4, 2, and 1, resulting in all zeros.

When completed, the binary number is 00110000. Another way to verify is to check which numbers are “on” in binary. In this case, the numbers 32 and 16 are “on,” and 32+16=48, confirming the accuracy of your conversion.

Explanation: After reading through the process of calculating the binary equivalent for 48, try applying the same steps to convert 146 into binary by filling in the remaining columns.

Your answer should be:

Step 2: Convert 222 into binary. Action:

Explanation: On a separate piece of paper, determine the values to place in each column to convert 222 into binary.

Your answer should be:

Step 3: Convert 119 into binary. Action:

Explanation: Determine the correct values for each column to convert 119 into binary. Your answer should be:

Step 4: Convert 135 into binary. Action:

Explanation: Find the values in the columns that will correctly convert 135 into binary. Your answer should be:

Step 5: Convert 60 into binary. Action:

Explanation: On a separate piece of paper, determine the values to place in each column to convert 60 into binary. Your answer should be:

Step 6: Convert 10100101 into decimal. Action:

Result: To convert from binary to decimal, place the eight binary digits into the appropriate columns. For example, with 11001100, the “on” bits correspond to 128, 64, 8, and 4. Adding these together gives 204, the decimal equivalent.

Explanation: After reading through the process of converting 11001100 to decimal, try the same approach with 10100101. Start by identifying the columns with binary ones and add their decimal values.

Your answer should be:

Step 7: Convert 11100011 into decimal. Action:

Explanation: Identify the columns with binary ones, find their decimal values, and add them together to convert 11100011 to decimal. Your answer should be:

Step 8: Convert 10110011 into decimal. Action:

Explanation: Identify the columns with binary ones, find their decimal values, and add them together to convert 10110011 to decimal. Your answer should be:

Step 9: Convert 00110101 into decimal. Action:

Explanation: Identify the columns with binary ones, find their decimal values, and add them together to convert 00110101 to decimal. Your answer should be:

Step 10: Convert 10010111 into decimal. Action:

Explanation: Identify the columns with binary ones, find their decimal values, and add them together to convert 10010111 to decimal. Your answer should be:

Step 11: You have finished the lab. Action: Since hardware is not needed for this lab, you can repeat it at any time.

Result: You can also assess your mastery of the material by taking the lab again. Instead of using the Sample Solution link, which guides you through each step, you can use the Suggested Approach link. This offers the same steps but without the walkthrough. This vLab was designed with built-in verification and detailed explanations to deepen your understanding of the concepts.
