1, The full form of DD is Demand Draft. It’s used on Business ,Banking in Worldwide

A demand draft is a method used by an individual to make a transfer payment from one bank account to another. Demand drafts differ from regular normal checks in that they do not require signatures to be cashed. In 2005, due to the increasing fraudulent use of demand drafts, the Federal Reserve proposed new regulations increasing a victim’s right to claim a refund and holding banks more accountable for cashing fraudulent checks

A demand draft can also be compared to a cheque. However, demand drafts are difficult to countermand. Demand drafts can only be made payable to a specified party, also known as pay to order. But, cheques can also be made payable to the bearer. Demand drafts are orders of payment by a bank to another bank, whereas cheques are orders of payment from an account holder to the bank.

2, The full form of DD is Decimal Degrees. It’s used on Academic & Science ,Units in Worldwide

Decimal degrees (DD) express latitude and longitude geographic coordinates as decimal fractions of a degree. DD are used in many geographic information systems (GIS), web mapping applications such as OpenStreetMap, and GPS devices. Decimal degrees are an alternative to using sexagesimal degrees (degrees, minutes, and seconds – DMS). As with latitude and longitude, the values are bounded by ±90° and ±180° respectively.

How to convert degrees,minutes,seconds to decimal degrees

One degree is equal to 60 minutes and equal to 3600 seconds:

1° = 60′ = 3600″

One minute is equal to 1/60 degrees:

1′ = (1/60)° = 0.01666667°

One second is equal to 1/3600 degrees:

1″ = (1/3600)° = 2.77778e-4° = 0.000277778°

For angle with d integer degrees m minutes and s seconds:

d° m’ s”

The decimal degrees dd is equal to:

dd = d + m/60 + s/3600

Example

Convert 30 degrees 15 minutes and 50 seconds angle to decimal degrees:

30° 15′ 50″

The decimal degrees dd is equal to:

dd = d + m/60 + s/3600 = 30° + 15’/60 + 50″/3600 = 30.263888889°

4, The full form of DD is Dolby Digital. It’s used on Technology ,Specifications & Standards in Worldwide

Dolby Digital, also known as Dolby AC-3, is the name for audio compression technologies developed by Dolby Laboratories. Originally named Dolby Stereo Digital until 1995, except for Dolby TrueHD, the audio compression is lossy, based on the modified discrete cosine transform (MDCT) algorithm. The first use of Dolby Digital was to provide digital sound in cinemas from 35 mm film prints; today, it is now also used for applications such as TV broadcast, radio broadcast via satellite, digital video streaming, DVDs, Blu-ray discs and game consoles.

5, The full form of DD is Disk Drive. It’s used on Computing ,Hardware in Worldwide

A disk drive is a technology that enables the reading, writing, deleting and modifying of data on a computer storage disk. It is either a built-in or external component of a disk that manages the disk’s input/output (I/O) operations.

A disk partition in a hard disk is also known as a disk drive, such as drive C and drive D, etc.

7, The full form of DD is Double Density. It’s used on Computing ,Data Storage in Worldwide

The double-density sign, also known as the double right heart border, is seen on frontal chest radiographs in the presence of left atrial enlargement, and occurs when the right side of the left atrium extends behind the right cardiac shadow, indenting the adjacent lung and forming its own distinct silhouette ^1-3.

If large enough, the left atrium can actually reach beyond the border of the right atrium; this is known as atrial escape ³. The right superior pulmonary vein can lead to a similar appearance ¹.

9, The full form of DD is Developmental Delay. It’s used on Medical ,Paediatrics & Child Health in Worldwide

Developmental disability is a diverse group of chronic conditions that are due to mental or physical impairments that arise before adulthood. Developmental disabilities cause individuals living with them many difficulties in certain areas of life, especially in “language, mobility, learning, self-help, and independent living”. Developmental disabilities can be detected early on and persist throughout an individual’s lifespan. Developmental disability that affects all areas of a child’s development is sometimes referred to as global developmental delay.

10, The full form of DD is Delusional Disorder. It’s used on Medical ,Psychiatry & Mental Health in Worldwide

Delusional disorder is a generally rare mental illness in which a person presents delusions, but with no accompanying prominent hallucinations, thought disorder, mood disorder, or significant flattening of affect. Delusions are a specific symptom of psychosis. Delusions can be bizarre or non-bizarre in content; non-bizarre delusions are fixed false beliefs that involve situations that occur in real life, such as being harmed or poisoned. Apart from their delusion or delusions, people with delusional disorder may continue to socialize and function in a normal manner and their behavior does not necessarily generally seem odd. However, the preoccupation with delusional ideas can be disruptive to their overall lives.
