Differentiate between linear addressing and matrix addressing modes with examples.
Ans:
Linear Addressing: Addressing is the procedure of selecting one of the cells in a memory to be written in or to be read from. So as to facilitate selection, memories are usually arranged by placing cells in Matrix form or in linear form.
Linear Addressing Mode: A single column which has n rows and 1 column (as like the 16X1 array of cells) demonstrated in fig.(a) is frequently termed as Linear Addressing. Selection of a cell simply implies selection of the corresponding row and the column is utilized.

Matrix Addressing Mode: The arrangement which needs the fewest address lines is a square array of n rows and n columns for a whole memory capacity of n x n = n2 cells. Such arrangement of n rows and n columns is commonly referred to as Matrix Addressing that is demonstrated in fig.(b).
