Lowercase and uppercase are two different cases used in writing. Here’s a detailed explanation of each:

Lowercase

• Definition: Lowercase refers to the small letters in the alphabet.
• Examples: a, b, c, d, e, f, etc.
• Usage: Commonly used in everyday writing and text. For example, in sentences and casual communication.

Uppercase

• Definition: Uppercase refers to the capital letters in the alphabet.
• Examples: A, B, C, D, E, F, etc.
• Usage: Often used for emphasis, titles, acronyms, or at the beginning of sentences and proper nouns.

Conversion from Lowercase to Uppercase

When you convert lowercase letters to uppercase, you change each small letter to its corresponding capital form. For instance:

• Lowercase: “hello world”
• Uppercase: “HELLO WORLD”

Methods of Conversion

1. Manual Conversion:
   • You replace each lowercase letter with its uppercase counterpart using a conversion table.
   • Example:
     • ‘a’ becomes ‘A’

2. Online Tools:
   • Websites and tools that automatically convert text from lowercase to uppercase. You input or paste your text, and the tool transforms it for you.
3. Text Editors and Word Processors:

4. Programming Languages:
   • Python: Use the .upper() method to convert text to uppercase.
   • JavaScript: Use the .toUpperCase() method.
