Every document or project contains tons of repetitive data. We may notice this after we write a document and see that we have used one specific word hundreds of times. In the file compression process, repetitive sections of a document or project are transformed into code. This code is a compact form of data, as it is quickly applied to any repeating information.
The advantage
· Less disk space (more data in reality)
· Faster writing and reading
· Faster file transfer
· Variable dynamic range
· Byte order independent
File Compression
Compressing files or images enables you to (sometimes dramatically) decrease the memory space that file will take up. Without going into to too much detail, it works by 'approximating' the information in the file, thereby lowering the detail and filespace. However, compression also reduces the quality of the file, possibly corrupting it if it is compressed too much!
I think answer is File Compression
There are many pieces of software that can test the quality of a file compression software. The file compression software itself can give a percentage of compression, as well as a verification of whether it is compressed properly. One can also check the 'checksum' of the file.
Tiffs typically produce larger files because their compression format maintains all the image data. Jpegs are "lossy," meaning their compression format works by discarding some of the data, reducing the number of colors stored in the image.
Compression ratio simply means the difference in size of the original vs compressed unit. Compression ratio is a commonly used term for internal combustion engine piston/cylinder compression and file compression. Ratios differ depending on the type of engine or the type of file being compressed. In file compression, 7zip has the highest compression ratio.
Here is what you do if you want to find out. find out how many pancakes will fit on the roof of a minivan if I have 4 apples and you have 9 pencils. Onc you find out the answer is purple, then it will become quite obvious. jk, i was looking for the answer to. sorry i couldnt help...

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.
