Text to Binary refers to the process of converting human-readable text into a sequence of binary digits (0s and 1s) that computers can understand. In computers, binary is the fundamental language for data representation. Each character in a text is represented as a unique sequence of binary digits, typically using a standard encoding system like ASCII or Unicode.
How Text is Converted to Binary:
Each character in the text is assigned a unique ASCII (American Standard Code for Information Interchange) or Unicode value, depending on the character set being used.
Each ASCII or Unicode value is then converted to binary. For example:
The character 'A' in ASCII has the decimal value 65, which is represented in binary as 01000001.
The character 'B' in ASCII has the decimal value 66, which is represented in binary as 01000010.
Example:
Let's convert the word "Hi" to binary using ASCII encoding.
Step 1: Get the ASCII values of each character
'H' → 72
'i' → 105
Step 2: Convert each ASCII value to binary
72 → binary: 01001000
105 → binary: 01101001
Step 3: Combine the binary codes
So, the word "Hi" in binary is:
01001000 01101001
Why Text is Converted to Binary:
Computers use binary to store and process data because they operate on binary logic (0s and 1s).
Converting text to binary allows computers to store text in memory, transmit it over networks, and perform operations on it.
This conversion is essential for tasks like data encoding, storage, and transmission.
