    • Negative numbers are represented as signed numbers.

    Concept Of Overflow

    • Occurs when a calculation result is too large to be stored within the available space.
    • Fixed Size Storage: Computers store numbers in a fixed number of bits.
    • Adding Too Much: When numbers exceed the maximum value, overflow occurs.

    Binary Coding

    • A way of representing information using only 0s and 1s.
