The process of getting a character from a keyboard to a screen involves scancodes, which vary by keyboard and language. Each key has two scancodes, one for pressing and one for releasing, and control characters also have codes. The computer examines the buffer and adds the character or attribute to the screen. Different keyboards have […]
ICD9 codes are numerical diagnostic codes used by insurance companies to determine whether to pay for medical procedures. They are used in conjunction with CPT codes to describe the patient’s medical condition and the treatment received. The coding system simplifies the billing process and allows for efficient comparison of codes. It is important to have […]
QR Code is a computer code used in various devices, created in 1994 in Japan. It contains data in both vertical and horizontal directions, can handle alphanumeric characters, symbols, binary and other code types, and has an error correction capability. It is superior to barcodes and is used in camera phones, business cards, and magazines. […]
Gray code is a cyclic binary code that allows for the expansion of standard binary code. It was developed by Frank Gray to control electromechanical switches and is now used in digital communications and other applications due to its single-bit modification property. It eliminates false position information and was first patented by Bell Labs in […]
A passcode is a password used for security on computers, websites, and other devices. It can be alphanumeric, case sensitive, and contain symbols. A strong passcode should be at least eight characters long and include uppercase and lowercase letters, numbers, and symbols. Access codes are needed for various accounts and devices, including ATMs, debit cards, […]
A computer program is built from source code entered into a source code editor. There are many types of editors available, each designed for a specific programming language. An advanced editor has many features that improve productivity, including auto-tagging and automatic code insertion. HTML editors are available for web developers. A computer program is a […]
Machine code is the basic language of all computers, consisting of “O” and “I” characters that determine actions. Programmers compile source code into machine code, which is read by the microprocessor in sets of characters. Machine code can be printed out as a dump using hexadecimal numbers. Machine code is the essential or basic language […]
Binary code simplifies information representation using only ones and zeros. Bit strings represent text or computer instructions, stored in flip flop circuits and binary files. Binary codes have been used throughout human history, such as in feng shui, Nigerian symbols, and Braille. Binary code can provide a way to simplify the representation of information. There […]
QR codes are scannable images that can transmit embedded information. Programs and websites can convert images into QR codes, which can be modified and even have images added to them. QR codes can be scanned using a phone or device with a scanner, and can still be scanned even if a small image is placed […]
Alt codes allow users to enter symbols and characters not on their keyboard by holding down the “Alt” key and typing a numeric code. This feature is useful for language-specific characters, copyright and trademark symbols, and system symbols. Alt codes can be used on keyboards without a separate number pad by activating an integrated number […]
Source code is the programming language used to write programs, including HTML and Java for websites. Viewing source code can help learn coding, but copying graphics from other websites is considered plagiarism. HTML source code has specific instructions for formatting text and hyperlinks. Free programs can help write source code for easy uploading to websites. […]
Source code viruses attack computer code, rendering programs unusable or generating errors. They are rare but can be difficult to combat as the source code is often not human-readable. Programmers need skill to develop them, and users can contract them through connected networks. Antivirus software can limit the risk of infection. A source code virus […]
Linux® source code is the programming instructions written by Linus Torvalds for the Linux® operating system kernel, available for free download under the GNU General Public License. It differs from a Linux® distribution, which includes bundled programs and a kernel. Programmers can use the source code to create their own distributions. Source code is a […]
The konami cheat code, also known as the contra code, was first seen in the game Gradius in 1986. It unlocks unique features in games and has become an iconic symbol of gaming culture. It is also used by web developers to unlock easter eggs or bonus features on their websites. The konami cheat code […]
Source code is a text format that describes tasks for a computer, compiled into machine language. Markup languages like HTML are often called source code. Programming languages have different syntax and conventions, and there are two legal models: open-source and closed-source. Every programming and markup language has its own particular form of source code, sometimes […]
HTML email code allows website owners to add a link to their email address, with customizable subject and body text. It is commonly used for website visitors to contact the owner and can be customized with design elements. Additional HTML coding or CSS can be used to add design.

Some tags stand alone, while others work in tandem as opening and closing tags. The material inside tags is specified by exact material or class of element. URLs and […]
Shellcode is a sequence of machine code injected into a computer’s memory to take control of a running program. Exploiting vulnerabilities in memory allocation and input validation, it can be written in low-level languages or scripting languages. Local and remote exploits can grant access to a machine or process. Shellcode is a sequence of machine […]
Health codes are local laws that regulate public activities and services to protect public health. They cover areas such as immunization requirements, water treatment, restaurant cleanliness, and sanitation policies.
