Why must the bitmap image for the file allocation be kept on mass storage rather?

memory is volatile and all files will be lost if system restarted or failure. mass storate is non-volatile it withstands across restarted and system failure (salmanarafath associate professor kmit 9394786444).

First, both the "indexed allocation" and FAT schemes use the idea of linked list, i.e., the blocks are linked one after another. However, in the "indexed allocation" scheme, each "next pointer" exists in the file block itself so that you need to visit the first (i-1)th blocks if you intend to access the ith block, such visits will introduce a lot of disk seek time/rotational latency. While, in the FAT scheme, all such linked list information are in stored in the FAT, which is one or several contigous blocks. Searching in FAT, you need only (i-1)lookups. Usually they are in the same block and you do not need to let the head move from one block to another, or even if you have to jump to another block(since FAT may be longer than what can be stored on a single block), it is still much faster than "indexed allocation".

Bitmap image is raster or pixel based image. Bitmap image is made up of pixels, every pixel in grid have its own position and color. Pixels are mapped to the pixel grid, that's why its name is Bitmap.

What is another term for Raster Graphics?
A bitmap graphic is also known as a raster image.
What image is composed of pixels on a grid?

What are the advantages of a bitmap image?
A bitmap image uses solid color pixels, which can be identified and recolored easily. A lossy compression image consists of shaded colors which cannot be easily exchanged.
What bmp stands for?
It stands for bitmap (image file).
How are bitmap images used in the fields of science and technology?
Yes, because they are keeping the whole information. Bitmap images are not necessarily the same as .bmp file, under a bitmap image it is generally understood any image type than saves the value of the image pixels as a pixel map.
Does indesign use bitmap or vector?
One can import both vector and raster/bitmap image formats into InDesign.
What do you call an image made out of bits and bytes?
That's called a digital image.
