What Is Boolean Logical Operator?

TechDogs Avatar

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!

Scanning Electron Microscope (SEM)

The scanning electron microscope combines two of the most valuable types of microscopes: They function in the same way as a standard microscope but are superior. Imagine you are looking at the very tip of your nose right now and attempting to see what's there. To get a close look at those minuscule hairs, you would need a powerful microscope, and if you squinted your eyes that intently at your face, you would probably have a headache. Imagine instead employing a scanning electron microscope, in which case the electrons would perform all the work for you. Since electrons make it possible for visual display results to have better integrity and resolution, objects can be seen more clearly and be used for cutting-edge research and engineering. You may not believe anything like this might be beneficial in regular life, but it absolutely is. We wouldn't be able to see how the tiny parts of bugs work together to form a whole, nor would we be able to see how much space there is between each atom in our bodies if we didn't have scanning electron microscopes. We would know nothing about our world if it weren't for the scanning electron microscopes that are currently in use. An electron beam is used to analyze whatever is being viewed in a scanning electron microscope, which is a type of microscope. It is also known as an SEM, and it is really interesting. The SEM traces the paths that electrons go through in an experiment. An electron gun is responsible for releasing electrons, which can be thought of as a light bulb that releases electrons rather than photons (light particles). Then, after passing through a few different components, such as scanning coils and a detector for backscattered electrons. You now possess some images obtained from the SEM! The backscattered electrons are transformed into signals and then delivered to a display screen. So as you're doing it, you're looking at photographs of your product on your computer or television screen - that's awesome!

Secure Hash Algorithm (SHA)

Secure Hash Algorithm is a set of algorithms developed by the National Institutes of Standards and Technology and other government and private parties. Cryptographic hashes (or checksums) have been used for electronic signatures and file integrity for decades. However, these functions have evolved to address some of the cybersecurity challenges of the 21st century. The NIST has developed a set of secure hashing algorithms that act as a global framework for encryption and data management systems. The initial instance of the Secure hash Algorithm (SHA) was in 1993. It was a 16-bit hashing algorithm and is known as SHA-0. The successor to SHA-0, SHA-1, was released in 1995 and featured 32-bit hashing. Eventually, the next version of SHA was developed in 2002, and it is known as SHA-2. SHA-2 differs from its predecessors because it can generate hashes of different sizes. The whole family of secure hash algorithms goes by the name SHA. SHA-3, or Keccak or KECCAK, is a family of cryptographic hash functions designed by Guido Bertoni, Joan Daemen, Michaël Peeters, and Gilles Van Assche. SHA-3 competition to develop a new secure hash algorithm was held by the United States National Security Agency (NSA) in 2007. To be a super safe and fast hashing algorithm, SHA3 was developed from this contest. The evolution of cybersecurity has led to the development of several "secure hash algorithms." Security is a crucial concern for businesses and individuals in today's digital world. As a result, many types of encryption have been developed to protect data in various scenarios. One of these is hash algorithms. All secure hash algorithms are part of new encryption standards to keep sensitive data safe and prevent different types of attacks. These algorithms use advanced mathematical formulas so that anyone who tries to decode them will get an error message that they aren't expected in regular operation.

Segregated Witness (SegWit)

It is time to get this party started! SegWit is an agreement implemented in the Bitcoin cyber currency community. It is also a soft fork in the Bitcoin chain and has been widely accepted by miners and users. So what does it all mean? In short, if you are running a node (a piece of software that helps keep the Bitcoin network stable), you need to upgrade your software by April 27th, or else your node will stop working. SegWit was activated as part of a hard fork on August 24th, 2017. The most important thing to note about SegWit is that it fixes transaction malleability, which has plagued miners and users for years. However, you do not need to worry if you do not want to upgrade your software. You will still be able to use Bitcoin just fine! It is confusing, but it is not that confusing. Segregated Witness (SegWit) is a proposal to improve Bitcoin implemented in August 2017. It allows for more transactions per block, which means lower fees and faster transactions.SegWit2x is a proposal that would include a hard fork months after the initial adoption of SegWit, creating two bitcoins. One of these versions would have SegWit, and one wouldn't, but both would be called "Bitcoin" and act as separate currencies. BIP 148 is another proposal that includes a user-activated hard fork and proposes implementing SegWit.SegWit is a soft fork, not a hard fork. SegWit is a technical improvement that allows more transactions to be processed simultaneously, making the network faster and more efficient. A hard fork is when developers propose changes to the protocol. If most users accept those changes, there will be two versions of that particular cryptocurrency, one for each side. The Bitcoin Cash (BCH) chain split from Bitcoin in August 2017 as an example of a crypto hard fork. Bitcoin Cash is the result of a hard fork.
