Logical Shift

It transfers the 0 zero through the serial input. We use the symbols ‘<<‘ for the logical left shift and  ‘>>‘ for the logical right shift.

Logical Left Shift: 

In this shift, one position moves each bit to the left one by one. The Empty least significant bit (LSB) is filled with zero (i.e, the serial input), and the most significant bit (MSB) is rejected. 

The left shift operator is denoted by the double left arrow key (<<). The general syntax for the left shift is shift-expression << k. 
 

Note: Every time we shift a number towards the left by 1 bit it multiplies that number by 2.

Logical Right Shift

In this shift, each bit moves to the right one by one and the least significant bit(LSB) is rejected and the empty MSB is filled with zero. 

The right shift operator is denoted by the double right arrow key (>>). The general syntax for the right shift is “shift-expression >> k”. 

Note: Every time we shift a number towards the right by 1 bit it divides that number by 2.

Shift micro-operations are those micro-operations that are used for the serial transfer of information. These are also used in conjunction with arithmetic micro-operation, logic micro-operation, and other data-processing operations. There are three types of shift micro-operations: 1.
