A digital rectal exam (DRE) is a quick and painless procedure where a doctor inserts a lubricated, gloved finger into the anus to check for growths, abnormalities, or collect a stool sample. It can also be used to palpate other organs. Discomfort may occur, and abnormal results may require further testing. A digital rectal exam […]
Computerized medical records are electronic versions of patient medical records that save time and money. They can be accessed quickly and securely, and patients benefit from easily accessible records during emergencies and the ability to control who can access their files. The goal is to have complete and accurate information about a patient stored in […]
Digital 3D uses polarization instead of color variants to create a 3D effect. Binocular vision is used to combine images in the brain. 3D movies require polarized glasses, while home TVs require a lens. Autostereograms are popular 3D art pieces. Digital 3D uses polarization to make a 2D image appear three-dimensional. Typically used in movies, […]

A digital voltmeter is a device used to measure the relative output voltage of electronic appliances, and is important for anyone doing electrical work. Digital models are considered superior to analog models, and can measure voltages from picovolts to megavolts and frequencies between zero and several megahertz. They are used in a variety of applications, […]
The first digital electronic calculator is a debated topic. In 1937, John Atanasoff and Cliff Berry invented the ABC computer, capable of solving simple equations. The ENIAC, built in 1946, was programmable and exhibited true logic-based multi-branching computational capability. A lawsuit in 1973 ruled that the ABC computer was the first electronic digital computer under […]
Analog technology records waveforms as they are, while digital converts them into sets of numbers. Digital recordings can be cleaned up, remastered, and easily copied. Digital technology accomplishes this through sampling, with the higher the sample rate, the more accurate the recording. Lower sample rates may be difficult to distinguish on portable devices, but the […]
DSL is a technology that allows digital data and voice transmission over telephone lines. ADSL is the most common type used for high-speed internet access. DSL requires filters to separate data and voice flows, and is sensitive to distance from hubs. A digital subscription line (DSL) is a technology that allows people to transmit digital […]
Digital TV signals are a more advanced way of transmitting data and images through television broadcasting. They are smaller and can transmit high definition television, additional program information, and real-time updates. Analog signals are larger and can still display a picture even when degraded.

A digital locker is a remote file storage space accessible via the internet, offered by companies for a fee. It centralizes files, allowing access from any device. Microsoft first used the term for its Windows Marketplace service, and digital lockers are now part of cloud computing. Two popular configurations are multimedia and archiving, with the […]
Digital photogrammetry uses computers to measure objects in photographs or videos. It requires information about the camera used and the desired size of measurements, and can use aerial or close-up photography to create 2D or 3D models. It has applications in various industries such as architecture, manufacturing, and police investigations. Broadly speaking, digital photogrammetry is […]
The digital divide is the gap between those who have access to technology and those who do not. It affects countries, populations, and races. Poorer people and underfunded schools may not have access to technology, while middle- and upper-class households and well-funded schools do. The divide also affects minority groups in the US. The gap […]
Digital art is created using digital technology and has expanded the traditional definition of art to include computer-generated drawings. Media art is a modern term for non-traditional art produced using technology. Digital technology has given rise to new art styles and forms, including animations, digital prints, and interactive installations. Digital art is becoming a reputable […]

They can also serve as a company’s primary web presence. A digital brochure is promotional material that is provided in a digital format for easy reading […]
The identity of the first digital computer is debated. The Atanasoff-Berry Computer (ABC) was declared the first electronic digital computer in a 1973 court case, but it was not programmable. The ENIAC and ABC both claimed to be the first digital computer, but the ABC was officially designated as such. The Z3 was the earliest […]
To become a digital cinematographer, one should consider formal filmmaking education, such as attending a film school or college, or completing a program in digital media.
