Answer:
It helps to give the geographic location of photos.
Explanation:
A geotag is added into the photography information when it's taken. That info is part of the EXIF information of a photo that lists a bunch of data related to the photo, like the camera brand, model, the aperture, the speed, the ISO, and so on.
That's assuming the GPS info is available of course, but if it's taken by a phone, it has the GPS info. Most mid-range and upper-range cameras have it too.
That information is used for example by Google Maps to present photos taken at a specific location.
Answer:
Data is stored on a hard disk drive as a result of magnetism. A file or data is represented in bits on a disk, with 1 representing a magnetized entity and 0 for an unmagnetized surface.
Explanation:
A hard disk drive (HDD) is an electro-magnetic tool for storing data in computing. It is made of moving parts like a platter and read/write head for reading and writing data to the disk.
To read or write data on a disk, the platter spins at a very high speed ( 5000 RPM to 10000 RPM), and the head, at the right surface, writes or reads a bit 1 as a magnetized surface and 0 as unmagnetized.
Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline, petrol, biodiesel blends, diesel fuel, fuel oil, or coal. It's pretty much exhaust gas.
A. White absorbs all light and reflects none so it is cooler.
