Programming languages like C and Java require compiling source code to produce object code that can be run on a computer. Object-oriented languages like C++ use object instances to make code easier to follow. Object code can protect source code and is used in both open source and payware applications. Programming languages like C and […]
To create a code of computer ethics, start with general principles and refine them to be specific to your environment. The code sets guidelines for ethical behavior and can be used in workplaces, schools, and other organizations. Look at other codes for inspiration and use specific language to avoid confusion. The Ten Commandments of Computer […]
Airport codes are three or four-letter codes used to identify airports worldwide. The most common three-letter code is the IATA code, used by customers and associated with the city or airport name. The four-letter ICAO code is used by air traffic controllers and pilots and designates the region, country, and airport. Some airports have both […]
Dress codes define appropriate attire for various settings, including workplaces, schools, and social events. They may specify what to wear or what not to wear, but modern codes often provide examples of appropriate dress to make it easier for guests to feel comfortable. Dress codes are sets of regulations governing what is and is not […]
Dead code is unused code within a software program that can be removed to improve efficiency, but may also cause problems if not handled carefully. It can accumulate over time and should be periodically reviewed to ensure functionality and security. Dead code is code within a software program that the program can’t reach or doesn’t […]
Dead code is unused code in software programs that can be left behind for various reasons. It can be safely removed to improve efficiency, but caution is needed to avoid causing problems. Dead code can be generated by debugging routines, reusing code, or inserting code for future use. It can waste time and space and […]
Prefix codes use binary code to represent letters and characters, with binary trees used to translate them. This reduces the amount of storage space required, with single bits used for frequently occurring characters and multiple bits for infrequent ones. Binary trees can increase storage space by up to 50%. A prefix code is the binary […]
Disneyland has a strict dress code for employees, including natural hair color, no visible tattoos, and no long hair for male cast members. The “Disney look” is meant to ensure guests feel comfortable. Cast members playing specific characters may have different requirements. All cast members wear costumes specific to their “land” and cannot visit other […]
HTML documents use tags to instruct browsers on how to display text. The code tag identifies text as computer code and can be styled using attributes like id, class, and style. Optional events like onclick can also be included. Browsers have default styles, but formatting may vary without attributes. All HTML documents consist of text […]
Hamming code detects and corrects errors in binary transmissions by adding parity bits in a sequence. Hamming(7,4) is the most common code. Parity bits check nearby positions, and errors are corrected by adding the bits in the check sequence. A Hamming code is a method of detecting and correcting errors in a binary transmission. It […]
Boilerplate code is pre-written code that can be used across multiple projects. It can be accessed through code libraries, but may create clunky code. The term comes from generic advertisements in newspapers. Programmers should consider if standard code is necessary for a project and avoid excessive coding. Stylistic elements like notes may also be included. […]
Code injection is when hackers insert malicious code into a website or program through a security vulnerability. This can cause harm by introducing malware, stealing information, or destroying the site. It can happen through user input and can be accidental or intentional. While usually bad, code injection can also be used for good, such as […]
To become a code inspector, a high school diploma or equivalent is required, along with knowledge of building codes and construction techniques. The job involves both office and fieldwork, and physical fitness is necessary. Code inspectors oversee construction and ensure compliance with codes and regulations. To become a code inspector, you must have earned a […]
A codeword is a password used for identification purposes to access critical information sites. Safer words include a combination of letters and numbers. It is recommended to avoid using pet and family names and to change the codeword at irregular intervals. A password is often case sensitive. A codeword is a word used for identification […]
One-time code is a program created for a single use, often used for small and simple tasks. It is created because it is easier than doing the task manually, but lacks stability for multiple uses. It is rarely built for more than one user and uses hack-filled coding. A one-time code is a program created […]
Unreachable code is code that cannot be executed in any context. It can be caused by errors in control structures or improper handling of code. It is different from dead code and can be fixed by careful analysis of a program’s flow of control. Unreachable code is programming code that cannot be executed in any […]
Chain codes are algorithms used to encode object outlines into a black and white image. The resulting code sequence can be used to redraw the object and compare it to other objects. Chain codes can be used in computer vision, image processing, and OCR programs. The algorithm involves finding the edge of an object and […]
Self-modifying code is a programming philosophy where the program can alter its coding when it runs. It improves itself without interaction and deletes unnecessary code. It is not the same as unintentional encoding changes and can improve processing and reduce path length. Self-modifying code is a programming philosophy in which the developer creates a program […]
Native code is programming code designed to work with a specific processor for optimal efficiency. Using an emulator to run incompatible software may result in reduced efficiency. Bytecode can be converted to native code, but not vice versa. Malfunctions with processors have decreased over time. Native code is a form of computer programming code configured […]
Code compression reduces file sizes by using algorithms to make a smaller piece of code represent a larger piece. Lossy compression discards some data, while lossless compression retains it uncompressed. Compressed files must be decompressed before use. Computer code can be thought of as the DNA of the digital world: the raw lines of data […]
