DC is an acronym that has two meanings that are widely used. The full form of DC is Data Compression and the other full form of DC is Direct Current.
So let’s go ahead and understand the full forms of both the DC in-depth and which one to be used at the right time.

• DC as Direct Current
DC can be abbreviated as Direct Current which is electric charges ( Electrons) flowing in one single direction from a negative charge to an area of positive charge through a conductor of electricity like a metal wire. In direct current, the intensity may be different but the direction of flow of electron remains the same. Direct Current can be produced through DC generators, solar cells, batteries and power supplies. The graph of DC current looks like a flat line and is mostly used in low voltage applications and works as a power supply for batteries and electronic devices. Before AC current was introduced DC was the first power to be distributed commercially.
We use Rectifier to convert AC to DC and use an inverter to convert DC to AC.



Advantages of Using a DC Supply
– Less Risk of electric shocks when running in a DC voltage below 48 volts
– Improves efficiency since it travels in a single direction therefore less electricity loss while transmitting which makes it more economical.
– Equipments are more efficient when powered through DC current
– DC transmissions require less structure and land while transmissions as compared to AC lines.

Applications of DC Supply
– Telecommunication: Higher DC voltage like 48V to 72V can be decreased to 36V, 24V, 18V, 12V, 8V, or 5V through a DC-DC converter and can be used for a telecommunication system.

Automobiles: Automobile systems mostly use DC of 12V or 6V. In certain automobiles, 42V is also used.

Domestic Supply: The most common use of DC is in domestic supply as domestic electronic circuits use DC power supply.

High-Voltage Power Transmission: DC is used through the bulk transmission of power supply from one place to another since the electrons move in a single direction therefore loss is comparatively less as compared to AC.

 

DC as Data Compression
DC also stands for Data Compression. It is a digital signal process in which data that is to be transmitted is compressed to reduce the size of the storage amount in bits. In Layman’s terms, it is a process in which data is shrunk before sending to reduce the amount of space.
Data compression is also known as source coding or bit-rate reduction. The most common formats are the ZIP and RAR which are used for the data compressions and many database management utilities, backup utilities use data compression to store maximum data in the minimum structured possible space.


Parts of DC
Two parts of DC are

– Lossy: As the name suggests in the Lossy compression method some part of the data is either deleted or truncated, the method finds the unnecessary information and deletes it before transmission.

– Lossless: It’s a more scientific method of compression in which data is first identified and check for redundancy and is removed statically. When the data is encoded before transmitting the size is effectively reduced however data remains intact.

Advantages of Data Compression
The main benefits of using data compression are

– Save more files for the space created by eliminating the unnecessary information
– Improves the speed of transfer since the data is shrunk into a smaller size
–  Reduce the cost of storing since you can store more data in a specific size limit
– Reduces the latency therefore easy for the machine and drives to search for the specific files and folders.

These are the two full forms of the DC and now you know which one needs to be used when required and the function and the benefits of both the DC.
