➢ Define the 4 (four) NUMBER SYSTEM�

The four number systems are:

1. Decimal Number System: Also known as base-10 system, it is the most commonly used number system. It consists of 10 digits (0-9) and a place value system where each digit's value is determined by its position in the number. The rightmost position is the units place, followed by tens, hundreds, and so on.

2. Binary Number System: Also known as base-2 system, it uses only two digits - 0 and 1. It is primarily used in computing and digital systems, as it represents data and information using on/off states or bits. Each digit's value is determined by its position, similar to the decimal system.

3. Octal Number System: Also known as base-8 system, it uses eight digits (0-7). It is commonly used in computer programming and represents numbers by grouping three binary digits into one octal digit. Each octal digit is equivalent to three binary digits.

4. Hexadecimal Number System: Also known as base-16 system, it uses sixteen digits (0-9 and A-F), where A represents 10, B represents 11, and so on up to F representing 15. It is widely used in computing and represents large binary values concisely. Each hexadecimal digit is equivalent to four binary digits or a nibble.
