In a logical left shift, the bits are shifted to the left by a specified number of positions. The bit (sign bit) is shifted out/discarded, and the vacant position on the is filled with a zero. Logical left shifts are primarily used for unsigned integer manipulation and simple bit operations. For example, if we perform a left shift of 1 on the binary number 10110101, it becomes .
In a logical right shift operation, the bits of a binary number are shifted to the by a specified number of positions. Similar to left shifts, new bits are introduced on the left side, and the rightmost bits are discarded. Each right shift effectively divides the number by for each position shifted. For instance, if you right-shift the binary number "1010" by one position, you get "0101," which is equivalent to dividing 1010 by 2^1 (2).
Logical shifts are used in computing and digital systems for several purposes, primarily in operations. They are used to manipulate individual bits in a binary number, such as clearing or setting specific bits. A logical left shift effectively multiplies a number by for each shift position, whereas a logical right shift divides a number by 2 for each shift position.
