What is BMP used for?
BMP is a file format for storing pictures on a computer. It stands for bit-map.
Why are BITMAP files larger than VECTOR files?
Bitmap files are bigger for two reasons, first BMP is an abbreviation of bitmap and every bit in the picture is mapped. Second Jpeg files are compressed using a lossy compression algorithm so some information is discarded. This is why you lose quality when you save a .bmp as a .jpg. In fact, every time you edit and save a Jpeg file, you lose more information, leading to a constant degradation in quality.--------------------------Update: Actually, while BMP is indeed an abbreviation for "bitmap", it is not true that every bit in a BMP file is mapped in all cases. BMP files come in a variety of "flavors", but in general they can be broken down into "compressed" and "uncompressed". In the uncompressed variant of BMP files, it is correct that each bit is indeed "mapped" and as such the files tend to be larger than many other common image file formats. However, most BMP files that are in circulation or created by applications such as MS Paint are compressed BMP files. BMP files use a type of compression called "run length encoding", or RLE. Run length encoding will basically identify strings of adjacent pixels that are the same color value, and use a shorthand to indicate how many of that color. For example, imagine that the symbol "*" represents a certain shade of blue, and all other punctuation marks represent various other colors. Imagine, too, that there is a long horizontal line of blue pixel (a line) within a picture, and surrounded by various other colors. The RLE version of that might look something like this:^2$1#1%1^2&1*240.1?1.1?.>1The pattern in this case (just a theoretical example of how RLE encoding works) is [PIXELCOLOR][REPETITON]. You will notice two things - there are two entries for every pixel reference (this can cause a RLE encoded BMP file to be LARGER than the original file -- if there are a whole bunch of 1-2 pixel areas and not many areas in the image that are solid colors; secondly, this "bloat" is significantly counteracted when the "*240" is encountered, since the original (uncompressed) would have looked like 240 asterisks one after the other.So, certain images compress better than others, and certain compression types are more suitable for certain image types. RLE is indeed one of the lossless types of compression. Lossless compression typically results in poorer compression ratios, but once decompressed, since none of the original image information has been discarded ("lost"), the decompressed version of the file will look exactly like the original.JPEG, which is an acronym for the Joint Photographic Experts Group which developed the algorithms behind this popular compression, works better on pictures than on images with large areas of identically colored pixels. JPEG is a lossy compression, meaning that each time the image is compressed with this format, certain bits of information are "approximated" to improve the compression ratio; thus, when the file is decompressed for viewing, there are changes to the image quality. JPEG compression can be adjusted to provide better image quality by sacrificing some of the compression, or can be adjusted to be more highly compressed but with a sacrifice of image quality. For most of the images on the in Internet, a balance is struck between good visual quality and good compression. However, since photographs are very common on the web, JPEG is perhaps the most popular format to be used online. JPEGs can provide a great compromise between acceptable image degradation and file size. However, since the compression algorithms have been specifically designed to work with the unique data that is seen insde a photograph, JPEG will usually wind up as a smaller file than BMP. However, if you convert an image that is only made from a small number of distinct colors, and those colors are mainly ground together in areas of the image, then a BMP file format might actually result in a smaller file.So, if you are trying to decide which format you want to use, you have to decide whether a certain degree of image degradation is acceptable or not, and you should test while retaining copies of the original files (just in case). Generally, for web pages and items that will be displayed from within a web browser, you want to stay away from BMP, because it is not supported by all web browsers (MSIE supports it, however). If you need the page background to show through the "negative space" of your image, and not be blocked out as the background color of the image, then you will do better abandoning JPEG and BMP entirely, and using either GIF or PNG and taking advantage of these file formats' (some variants') inherent support for transparency and/or an "alpha channel."
Difference between tiff and bmp image?
bmp is a bit mapped image = you save what you see ... every bit on your screen is stored into memory. tiff is Tagged Image File Format = there are codes (tags) to tell the computer how the file (image) was saved ... it uses various types of compression to shrink the image as stored in memory.
Four type of digital computers?
Every computer is digital. The word digital revers to the binary system, where information such as a picture or a song is stored as a series of ONES and ZEROES. Music files are called .WAV files or .MP3 or .WMA. Picture files are .JPG or .BMP or .PNG.
What do you think computer save imanges as?
Mainly saved as jpeg (joint photographic experts group) or bmp (bitmap) or gif (graphics interchange format).
What kinds of files end with .BMP?
Bitmap image files end with the file extension .BMP.
How can you recognize your picture files?
Picture files no matter name they have they will definitely have an extension like xx.jpg . bmp and may more. window automatically will search for these files extension if asked to do so.
Example of a file extension?
.xls or .xlsx for Excel spreadsheets. .dbf for dBase databases. .bat for Batch files. .bmp for Bitmap files. There are a huge amount of others.
What basic type of files have file extensions of bmp and gif and or jpg?

What is the extension of the bitmap file?
.bmp
Which compression type using in BMP image file?
Which compression type using in BMP image file? The BMP image file normally doesn't use any compression at all. This is why usually they are large files and are not used on the web.
What is the extension file name of ms paint?
.bmp, by default, as in bitmap.
What is the file extension for a DVD RW file?
any extension can be used because the DVD disk is not the file. there are likely going to be hundreds if not thousands of files on a DVD. Some could be video files, (.mov, .wmv, .mpg, or others) some could be picture files (.bmp, .jpg, .gif, and many others) some could be executable files .exe, or zip files .zip
In what format are pictures saved that are emailed?
The file formats and extensions jpeg, jpg and gif are used to save pictures. The format and extension bmp refers to files made with Paint and are larger files generally. The format and file extension ttf are archival-quality photos; some people use home scanners but make archival files.
How does the BMP file format impact on the size of the file?
BMP files tend to be very big, as they are not compressed.
What is abbreviation of BMP in computer?
BMP the file name extension for the Bitmap image file format.
