📌 What is ASCII?

ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns a numeric value to every letter, digit, punctuation mark, and control character.

👉 Example ASCII values:

• A → 65
• B → 66
• a → 97
• 1 → 49
• Space → 32

ASCII codes range from 0 to 127, covering all standard English characters and symbols.

📌 What is Binary?

The Binary system is a base-2 number system that uses only two digits: 0 and 1.

👉 Examples:

• Decimal 2 → Binary 10
• Decimal 5 → Binary 101

Computers use binary because hardware circuits (transistors) can only be ON (1) or OFF (0).

⚡ Why Convert ASCII to Binary?

1. Data Storage – Computers store text internally as binary.
2. Networking – Text sent over networks is converted into binary packets.
3. Programming – Developers often debug ASCII-binary conversions.
4. Cryptography – Binary representation is used in encryption.
5. Education – Students learn ASCII-binary conversion in computer science.

🛠️ Manual Conversion: ASCII to Binary

The conversion process is two-step:

1. Find ASCII Value of Character
   Example: Character A → ASCII = 65
2. Convert ASCII Value into Binary
   Convert Decimal 65 into Binary:
   • 65 ÷ 2 = 32 remainder 1
   • 32 ÷ 2 = 16 remainder 0
   • 16 ÷ 2 = 8 remainder 0
   • 8 ÷ 2 = 4 remainder 0
   • 4 ÷ 2 = 2 remainder 0
   • 2 ÷ 2 = 1 remainder 0
   • 1 ÷ 2 = 0 remainder 1

Reading bottom to top → 1000001

✅ Final Answer: Character A = Binary 1000001

👉 Example 2: Convert “Hi” into Binary

• H → ASCII 72 → Binary 1001000
• i → ASCII 105 → Binary 1101001
  Final Result = 1001000 1101001
