DC FULL FORM

Full Form of DC : Direct current

What is the Full form of DC?

No:1. The full form of DC is Direct current.
No:2. Direct current is the unidirectional flow of an electric charge.
No:3. Direct current may flow through conductors like wire, but also can flow via the semiconductors, or through the vacuum.
No:4. The electric current flows in a constant direction, distinguishing it from alternating current (AC).

Examples of direct current

No:1. The primary use of DC is to the power supply and also to charge the batteries for electrical equipment. The mix of plus & minus signs, a dotted line or a straight line is available in DC.
Example: Flashlights, Mobile phone batteries,flat-screen TV & electric vehicles.

How can we convert AC to DC and DC to AC?

No:1. The alternating current (AC) can be converted in to direct current by using a rectifier.
No:2. The direct current (DC) can be converted into alternating current by using an inverter.

Benefits of DC

No:1. The electrical device is more powerful when charged from DC.
No:2. Less chance of electrical shocks if the voltage is less than 48V
No:3. The DC transmission line can transfer more power over long distances with less loss of electricity. It also enhances performance and decreases the cost of transmission.
No:4. Compared to AC lines, DC transmission lines need less ground, narrower structural support.

Another full form of DC

No:1. Other full form of DC is Data Compression.
No:2. To minimize the amount of storage in bits, DC is a digital signal mechanism wherein data to be sent is compressed.
No:3. After applying DC, you can conclude that the space of the data storage is lower than normal.
No:4. Transmission of data dramatically decreases data storage space and transmission power.
No:5. It is also recognized as reducing bit-rate or source coding.
No:6. Back utilities, database management system and so on, usually use the method of data compression.

Parts of data compression

Data compression mainly has two parts.

No:1. Lossless

a). Compression is accomplished by the detection and removal of any statistical redundancy in the lossless compression process.
b). For example, when we encrypt a source of data before transmitting it, the size is decreased quickly and information stays unchanged and unaffected as well.

No:2. Lossy

a). Some pieces of information are removed or lost in the lossy compression process.
b). Since, before transmission, it recognizes and then deletes the unnecessary content.

Advantages of DC

No:1. As less bandwidth is demanded the downloading of compressed data, DC increases the speed of data transfer.
No:2. DC helps you to store many files in the storage space available, for example. Compression without a loss will minimize a file to 50% of its original size.
No:3. DC helps you to decrease the price of information storage because you can store many files in the provided storage capacity after compression.
No:4. The tiny file images can be scanned faster on tape, to reach a specific file that reduces delay.
