DC Full Form - Data Compression
- Here you’ll get the solution for the following DC related questions, full form of DC , what is the full form of DC , dc full form , ac dc full form
Data Compression
- DC stands for Data Compression.
- DC is a digital signal process in which data to be transmitted is compressed to reduce the storage amount in bits.
- In other words, you'll say that data storage space is reduced than usual after applying DC.
- Data transmission greatly reduces data space for storing and transmission capacity.
- It's also called source coding or bit-rate reduction. Database management system, backup utilities, etc use data compression method widely.
- There are many file compression methods but ZIP and ARC are mostly known file formats.
Process of Data Compression
Two Parts of DC
Types of Data Compression
- Lossy : In lossy compression method, some part of data is deleted or lost. Because it identifies then delete the unnecessary information before transmission.
- Lossless : In lossless compression method, compression is done through identifying and eliminating any statistical redundancy. As an example, once we encode a data source before transmitting it, its size is effectively reduced and data also remains intact and unchanged.
Benefits of data Compression
Benefits of Data Compression
- Faster file transfer : It improves the speed of file transfer as less bandwidth is required to download the compressed files.
- More Storage Capacity : It allows you store more files within the available storage space, e.g. Lossless compression can reduce a file to 50% of its original size.
- Reduces Cost : It allows you reduce the cost of storing data as after compression, you'll store more files within the given space for storing.
- Reduces latency : On tape, the small file images are often scanned faster to reach a particular file that reduces latency.
DC Full Form - Direct Current
Direct Current
- DC also can be abbreviated as Direct Current.
- Direct Current are often defined as electric charges (electrons) flowing in one single direction, i.e. from a part of negative charge to a part of positive charge through a conductor like a metal wire.
- The intensity of the present may vary but the direction remains the same.
- It's produced by sources like DC generators, batteries, solar cells and power supplies. Once you will draw a DC graph, it'll appear as if a flat line.
- DC is used to charge batteries and work as power supply for electronic devices and is mostly used in low voltage applications.
- It had been the first power to be transmitted commercially, but now it's been widely replaced by AC current.
- To convert AC to DC we use rectifier, and to convert DC to AC we use inverter.
Types of Direct Current
Advantages
- Most equipments are generally more efficient when powered from DC
- Less risk of electrical shocks when voltage is below 48 Volts
- Over long distances, DC transmission line can transmit more power with less electricity losses. It also improves efficiency and lowers the transmission cost.
- DC transmission lines require less land, narrow structure (smaller footprints) as compared to AC lines.
Applications
- Domestic : Most electronic circuits use DC power supply.
- Automotive : Automotive systems mostly use DC of 12 V but some uses 6 V or 42 V DC.
- Telecommunication : Higher DC voltages like 48V to 72V power is converted to lower DC voltages like 36V, 24V, 18V, 12V, 5V through a DC-DC converter can be used for telecommunications system.
- High-Voltage power transmission : DC is used for the bulk transmission of electric power from a high-voltage direct current.
