What is the Full Form of JPEG?

-
JPEG Full Form is Joint Photographic Experts Group. It is method of compressing digital images which are produced by digital photography. It is used most often with its file name extension .jpg or .jpeg. It is generally used to compress digital images. It is a lossy compression technique because some information is lost while compression. It is the format used to store digital graphics and photos. A lossy compression is used to save a jpg file. Most often, this file type is used to store omages captured by digital cameras and is widely used for website graphice photos.
The PNG file excels when the image has large, uniformly colored areas. The lossless PNG format is best suited for editing pictures, and the lossy formats, like JPG, are best for the final distribution of photographic images, because in this case JPG files are usually smaller than PNG files. The Adam7-interlacing allows an early preview, even when only a small percentage of the image data has been transmitted. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-color, grayscale, and truecolor images are supported, plus an optional alpha channel. PNG is designed to work well in online viewing applications like web browsers so it is fully streamable with a progressive display option. PNG is robust, providing both full file integrity checking and simple detection of common transmission errors. Also, PNG can store gamma and chromaticity data for improved color matching on heterogeneous platforms. Some programs do not handle PNG gamma correctly, which can cause the images to be saved or displayed darker than they should be.

Some facts about JPEG :-

  • It supports a maximum image size of 65535×65535
  • JPEG file can be converted to many formats
  • It compresses an image into a stream of bytes and decompressed back into an image 
  • It was developed by the Joint Photographic Experts Group
  • File extensions of Joint Photographic Experts Group are : .jpeg, .jpg, .jfif, .jpe, .jif

What is the Full Form of LASER?

-
LASER Full Form is  Light Amplification by Stimulated Emission of Radiation.    These radiations have very specific properties that they use in different types of applications.  It is used to build a wide range of electronic devices, including CD Rom, Bar Code Reader. The light emitted by these devices are thin and consistent.    It is a breed of cattle which was born in the French of Massif Central. These are a large breed, the number of women is 700 to 750 kg and 1.40 meters long. They have thick red or black coat thick, and long, purple-shaped, light colored horns and small percentages are born without natural beings. In the 19th century, breeder Ernest Tystader D'Vasas established breed by selective reproduction.  Originally breed for work, this double purpose is to face extreme variations in the temperature of the cow, its fertility, its reproduction, its milk (even if it was necessary to give milk for the presence of calf, and its meat). Was th...

What is the Full Form of LPG?

-
LPG Full Name is  Liquefied Petroleum Gas.   It is a flammable mixture of hydrocarbon gases used as a fuel in heating appliances and vehicles,  a clean and efficient source of energy having wide range of applications. It is a flammable mixture of hydrocarbon gases including Propane and Butane. It is extracted from crude oil and natural gas, and thus a non-renewable source of energy. Cooking- LPG has a very wide of uses and commonly used cooking fuel in several countries. It is especially used  by the central Government. It was once a popular fuel. Its supply has now reduced with the increased use of town gas. LPG is a popularly used cooking fuel.  In the safety font LPG cylinders must be updated to new standards in safety and user experience, giving a huge contribution for domestic usage. Uses of Liquefied Petroleum Gas (LPG) Motor Fuel -This is also used in the engine. It seems less than the cost of other fuels. LPG is used for internal combustion en...

What is the Full Form of TFT?

-
TFT Full Name is Thin Film Transistor. This is a special field-effect transistor. The thin film of dielectric layers and metal contact with an active semiconductor layer on the substrate. There is a normal substrate glass, because the primary application of TFT is in liquid crystal display. It is different from conventional transistor, where semiconductor material is usually substrate, such as silicon wafer. The use of liquid crystal displays is a direct-driven image element with the same simple display in the calculator and other devices, and therefore, the voltage of only one segment of these types of displays can be easily applied. This would be impractical for a bigger display, because it will have a lot of pixels, and in this way for each of the three colors, to avoid this, millions of connections per pixel (red, green and blue) need a problem Yes, the pixels should be known in rows and columns, which will reduce the number of connections from thousands to thousands.
