    Study Notes

    Data Representation in Digital Computers

    • In digital computers, data and instructions are stored in computer memory using binary code represented by 1s and 0s, known as bits.
    • The data, including digits, alphabets, and special characters, is converted into bits to be understood by the computer.
    • Number systems use well-defined symbols called digits and are classified into two types: non-positional and positional number systems.
    • The non-positional number system was historically used for simple calculations like additions and subtractions.
    • It consists of different symbols to represent numbers, and the Roman number system is an example of this type, using symbols like I=1, V=5, X=10, and L=50.
    • The non-positional number system is not effective for performing arithmetic operations.
