What Is Boolean Logical Operator?

Allow us to explain what Boolean Logical Operators are. Simply put, they are the instruments with which we compare and manipulate binary values in computer programming and digital logic circuits. Don't worry if you've never heard of binary; we'll explain it shortly. AND, OR, and NOT are the three primary Boolean Logical Operators. How about we take them apart, one by one? The operation of AND is simple: if both inputs are true, the result will also be TRUE. The AND operator takes two inputs and returns TRUE if both are true for the given expression. Both assumptions (A and B) must be TRUE for the result to be TRUE. No brainer, right? There is a bit more leeway with OR. Similarly, it takes two arguments and returns TRUE if both are true. The OR operator takes two inputs and returns TRUE if either is true or both are true. If both A and B are false, the OR operator will always give a false result. The word "not" differs from the other two in keyways. One input is required, and the output is the inverse of that input. As a result, if we input A and it is true, the NOT operator will return FALSE, while if it is false, it will return TRUE. If the input is ON, then NOT will turn it OFF, and likewise, if the input is OFF, then ON will be restored. Let's dive deeper into the world of binary now. Numbers in the binary system can only be a zero or a one. Since it is easy to understand and implement, binary is widely used in computer programming and digital circuitry. Each digit stands for a bit of a discrete chunk of data. For example, a binary number 1101 has four bits: two on the left and two on the right. Let's see this all come together with an illustration now. To illustrate, we want to compare two inputs, A and B, using Boolean Logical Operators. The binary representation of the letter A is 1011, and the binary representation of the letter B is 0101. The three main operators would be applied as follows: Since the only bit in both A and B that is TRUE is the rightmost bit, the result of ANDing the two is 0011. Since both A and B contain TRUE bits, the OR operation between them would produce the value 1111. NOTE: NOT A would return 0100 since it inverts all of A's bits, turning ones into zeros and ones into ones. There you have it! Although working with Boolean logical operators can be intimidating at first, it's quite enjoyable once you get the hang of it. So, my friend, start playing with those binary values with all the wit and merriment you can muster!
