Set:
A set is a collection of distinct, symbols unordered objects. Sets are typically collections of
numbers, though a set may contain any type of data
Data Coding System (Number System)
Number Conversion
DECIMAL TO BINARY
1. Convert decimal integer number into binary
Start dividing the number by 2 and continue the process till the
quotient is 0.
K
Error Correction and Detection Code
When binary data is transmitted and processed. It can be corrupted in passage because
of noise or other.
The 1s may get change in 0s and 0s may get change 1s.

2. Non-Weighted Code
1. Weighted Code
If each position of number represent a specific weight then coding schema
called weighted code.
