A string is a sequence of characters, such as letters, numbers, and symbols, used to represent textual data in computer programming. It’s a fundamental data type used to store and manipulate text-based information. Strings are widely utilized in various applications, from simple word processing to complex web development.
Binary refers to the base-2 numeral system, which uses only two symbols, typically “0” and “1,” to represent numeric values and data. In computing, binary is crucial as it forms the basis for all digital communication and data storage. Computers process and store information using binary code, where each digit (bit) represents a power of 2, allowing for efficient electronic operations.
Converting a string to binary involves representing each character in the string as its corresponding binary value. Here’s how to do it:
Here’s a simple example:
Let’s convert the string “Hello” to binary:
H -> ASCII: 72 -> Binary: 1001000
e -> ASCII: 101 -> Binary: 1100101
l -> ASCII: 108 -> Binary: 1101100
l -> ASCII: 108 -> Binary: 1101100
o -> ASCII: 111 -> Binary: 1101111

To convert a string to binary, you need to represent each character in the string using its corresponding binary code. This can be done by converting the ASCII or Unicode value of each character into binary format. Concatenate these binary codes to create the binary representation of the entire string.
A string in binary code is a sequence of binary values representing the characters in a string. Each character is encoded using its binary equivalent, typically following the ASCII or Unicode standard. This binary representation allows computers to process and store textual data as a series of ones and zeros.
Converting words to binary involves converting each character in the word to its binary equivalent using ASCII or Unicode values. Start by finding the binary code for the first character, then move on to the next characters until you've converted the entire word. Combine these binary values to create the binary representation of the word.
Converting a string to bytes involves encoding the string using a specific character encoding scheme, such as UTF-8. In Python, you can use the encode() method to convert a string to bytes. This encoding process assigns unique byte sequences to characters in the string, allowing it to be stored and transmitted as bytes.
A byte string is a sequence of bytes that represent textual or binary data. Unlike regular strings, which are composed of characters, byte strings are composed of individual bytes. Byte strings are commonly used to handle binary data, file input/output, and network communication, where data needs to be treated as a series of bytes rather than characters.
