Concepts

What Is Metcalfe’s Law?: Complete Explanation Metcalfe’s Law is one of the foundational principles of network economics. It suggests that as a network grows, its value grows much faster than its user base. The idea behind Metcalfe’s Law is that, while a network’s cost generally grows as a direct proportion of its total number of […]

What is an Air Gap?: Complete Explanation If a device can be reached, it can be hacked. That, in a single, simple sentence, expresses what is perhaps the core truth of network and computer security. The entire field of cyber security, with all of its principles, techniques, and methods, proceeds with that fact lurking always […]

What are Deep Fakes?: Complete Explanation People who have watched Mark Zuckerberg talk about how he has total control of data for billions of individuals have watched a deep fake. Jon Snow apologizing for the ending to the Game of Thrones show was also a deep fake. These are just a few examples of deep […]

What is Surface-Mount Technology?: Complete Explanation Surface-Mount Technology, or SMT, is a method for attaching electrical components directly onto the surface of a printed circuit board, or PCB. This process allows for automated production to complete more of the required assembly to create a working board. It lowers the cost of production and increases the […]

What is SFTP?: Complete Explanation Secure File Transfer Protocol, also known as SFTP, is a secure file transfer protocol that uses secure shell encryption to provide protection when sending and receiving files. SFTP is similar to FTPS in that it encrypts data as it travels between systems using AES and other techniques. SFTP: An Exact […]

What is Microcode?: Complete Explanation The definition of microcode is a basic instruction set used in a complex instruction set computer (CISC). These instructions add a layer of complexity to improve the performance of basic operations. As the lowest specified level that interacts with machine code and source code, microcode performs control-level operations in ways […]

One of the joys of mathematics is the discovery of a numbers list that mirrors patterns found in nature. These instances create a sense of belonging in the universe, a sense of some grand cosmic interconnectedness — it’s practically like magic, but rooted firmly in science and mathematics. The Fibonacci Sequence is one such example. […]

Whether you liked algebra class or not, there’s no denying that algebra is one of the most vital components of all of mathematics. Given this extreme importance, algebra tends to get pretty complex. As is often the case with this area of math, a phrase like “binary operator” sounds a lot more complicated in theory […]

Databases come with pros and cons. For one, they can be a handy way to organize large amounts of important numbers and figures. However, if that database isn’t organized properly, it can be quite difficult to work with. For those who rely on a database management system (DMBS) in their day-to-day operations, you know how […]

What is Hashing: Complete Explanation A hash function is a method for converting strings of different lengths into fixed-length strings called hash values or digest. It can be used to scramble passwords into strings of authorized characters. It can encrypt communications between web servers and browsers. It can be used to hide sensitive data from […]

What is GUID?: Complete Explanation In the computer science field, data is found in a great abundance. There is so much data tracking and recording that quite often the same data can be present within a single database. As you might imagine, identical data or duplications of data can be problematic for effective programming as […]

What is C++? C++ is one of the best-known and most ubiquitous computer programming languages in the world, casting a long shadow over the entire history of computer science. Even now, nearly four decades after its initial emergence, it continues to be extremely popular. It continues to loom large in an impressively diverse array of […]

What is POAP: Complete Explanation Proof of Attendance Protocol, or POAP(Poh-App), is an Ethereum-based smart contract protocol used to manage tradable event tokens, reward distribution, and event attendance. It was designed in 2017 to overcome issues with the Proof of Work (PoW) consensus protocols previously used. With POAPs, event coordinators/organizers can quickly put together an […]

What is DAO: Complete Explanation A DAO, or decentralized autonomous organization, is a type of business organization that can be set up to run just about any kind of business. However, it does so in a rather unique way. In order to be truly decentralized, the power of decision-making and process has to be decentralized. […]

What Is Web 3.0: Complete Explanation Web 3.0, also known as Web3, describes the future that many believe the web is heading toward. It promises intelligent connectivity, dynamic compatibility, and more democratic functionality. It isn’t just a new way to build websites but may become an entirely new way to experience the internet. It all […]

If you have been using the internet for a while, you may have stumbled across the term “copypasta” before. In fact, this little meme has been around since 2006 and has evolved into its own branch of internet humor that is alive and well nearly a decade later. If you’ve ever tried to make sense […]

What is the Dark Web: Complete Explanation The dark web refers to a part of the internet consisting of hidden sites that can only be found through specific browsers. The sites allow users to browse anonymously, and unlike the conventional websites, sites on the dark web are guarded by encryption software such as the Tor […]

What Are Self-Driving Cars: Complete Explanation Self-driving cars are also known as autonomous vehicles, robotic or robocars, and driverless cars. Tesla is an example of one of the companies that make these cars, with technology that allows them to move safely with minimal human input. The benefits of these vehicles have shown promise for many […]

What Is Bitcoin? – Complete Explanation Bitcoin is a decentralized electronic cash system that was born and lives entirely on the internet. It’s a digital currency that provides safe and easy peer-to-peer online transactions and doesn’t depend on any central authority. Bitcoin is the first and most famous of the around 50,000 cryptocurrencies currently competing […]

What is the Homebrew Computer Club: Complete Explanation The Homebrew Computer Club was a group of computer hobbyists who met in Menlo Park, California between March 1975 and December 1986. It was an informal meeting of the minds for electronics enthusiasts who gathered to trade parts, circuits, and build information for personal computing devices designed […]

What Is Combinatorics: Complete Explanation Combinatorics is the study of counting permutations and combinations of the sets of elements within a finite structure. The entire scope of combinatorics has not been universally agreed upon, however, the most common form referred to is enumerative combinatorics which concentrates on counting the number of certain combinatorial objects. However, […]

What Is Moore’s Law? – Complete Explanation In 1965, Gordon Moore, an American engineer who went on to co-found Intel, hypothesized that the modern pace of invention would find a way to increase at a steady rate the amount of transistors that manufacturers could pack into a given area on an integrated circuit. He predicted […]

What is RDBMS: Complete Explanation Data is internet gold. It can be anything from statistics to names to locations. Everything that flows through the internet is data, even games. Each piece of data is valuable in its way. In order to make use of this data, it has to be stored, parsed, and made accessible. […]

The world runs on communications. From ledger checking and balancing to pen-pals, everyone has a need to transmit information. Unfortunately, not everyone is trustworthy which means we have always had a need to send private communications. Throughout history, mankind has found ways to hide their messages that only the correct recipient could interpret. This is […]
