Electronic – Digital representation
Computers interpret every signal as “on” or “off.”
1 (“on”) and 0 (“off”) are referred to as bits.
Eight bits is a byte. Each byte represents a unique character.

Data Representation – How it works?
Each ASCII number represents an English character
Computers that run the Windows operating system use the set of Extended ASCII definitions defined by the American National Standards Institute (ANSI). ANSI standard sample ASCII

Summary
Computing Concepts - Part 1
Computer and Internet technologies have changed how society communicates, socializes, and conducts business.
A computer takes data, converts the data into a meaningful form, displays the processed data as information for the user to see, and stores the information for later use.
