📂 Contents

1. IP Addressing

   • Explanation of IP address classes (A, B, C)
   • Subnet masks
   • CIDR ranges
   • Example addresses:
     • 30.0.0.0 → Class A, /8
     • 162.53.0.0 → Class B, /16
     • 193.25.20.0 → Class C, /24

2. Decimal Numbers

   • Basic explanation of the decimal system
   • Place values using powers of 10
   • Worked example: breaking down 537 into place values

3. Binary Numbers

   • Definition and explanation of binary (base-2 system)
   • Place values using powers of 2
   • Representation of an 8-bit binary address
   • Example: 11111111 = 255 in decimal

4. Conversions

   • Step-by-step conversion of 30.0.0.0 from decimal to binary
   • Conversion of binary 00011110.00000000.00000000.00000000 back to decimal (30.0.0.0)
