What Does 165 In Binary Mean?
Introduction
Binary numbers are a fundamental concept in computer science and digital systems. Unlike our decimal system, which uses ten digits (0-9), the binary system only uses two digits: 0 and 1. This article aims to explore what 165 means in binary and how to convert it.
Understanding the Decimal System
Before diving into the binary representation of 165, let’s review our familiar decimal system. In the decimal system, each digit’s position carries a weight that increases by a power of 10 from right to left. For example, in the number 165, the digit 5 is in the one’s place, the digit 6 is in the ten’s place, and the digit 1 is in the hundred’s place. The value of each digit depends on its position and its associated weight.
Converting Decimal to Binary
To represent decimal numbers in binary, the same concept applies, but the weights are powers of 2 instead of 10. To convert 165 to binary, we need to determine the largest power of 2 that is less than or equal to 165. This power of 2 will have a 1 in its corresponding binary position.
Step-by-Step Conversion
1. Start by finding the largest power of 2 that is less than or equal to 165. In this case, it is 2^7 (128). Place a 1 in the 2^7 position (128) and subtract it from 165, leaving a remainder of 37.
2. Repeat the process with the remainder of 37. The largest power of 2 that is less than or equal to 37 is 2^5 (32). Place a 1 in the 2^5 position (32) and subtract it from 37, leaving a remainder of 5.
3. Continue with the remainder of 5. The largest power of 2 that is less than or equal to 5 is 2^2 (4). Place a 1 in the 2^2 position (4) and subtract it from 5, leaving a remainder of 1.
4. Lastly, assign a 1 in the 2^0 position (1), as this is the smallest power of 2. Subtracting it from 1 leaves no remainder.
Binary Representation of 165
By following the steps mentioned above, we can represent 165 in binary as 10100101. Each digit in the binary representation corresponds to a power of 2, from left to right: 128, 64, 32, 16, 8, 4, 2, and 1. Adding the decimal values of the positions where a 1 appears results in 165.
Conclusion
Understanding binary numbers allows us to communicate and comprehend how information is processed in digital systems. Converting decimal numbers, like 165, to binary helps us visualize their representation in the binary system. By following the step-by-step conversion process, we found that 165 in binary is 10100101.
