How do you calculate compressed data?
To determine the compression ratio, divide the size of outputFile value by groupPages value.
For example, if the size of outputFile value is 40 000 bytes and the size of the group of pages is 200 000 bytes, then the compression ratio is 40000/200000 or 0.20 (5:1 compression)..
How is data compression possible?
Data compression algorithms reduce the size of the bit strings in a data stream that is far smaller in scope and generally remembers no more than the last megabyte or less of data.
File-level deduplication eliminates redundant files and replaces them with stubs pointing to the original file..
Text compression techniques
Decompression is the process of restoring compressed data to its original form.
Data decompression is required in almost all cases of compressed data, including lossy and lossless compression.
Similar to compression of data, decompression of data is also based on different algorithms..

What are the 2 types of data compression?
What are the two types of data compression? There are two methods of compression – lossy and lossless.
Lossy reduces file size by permanently removing some of the original data.
Lossless reduces file size by removing unnecessary metadata..
What is compression in math?
When we multiply a function by a positive constant, we get a function whose graph is stretched or compressed vertically in relation to the graph of the original function.
If the constant is greater than 1, we get a vertical stretch; if the constant is between 0 and 1, we get a vertical compression..
What is compression in maths?
A compression occurs when a mathematical object is scaled by a scale factor less in absolute value than one.
When a compression occurs, the image is smaller than the original mathematical object.
If the scaling occurs about a point, the transformation is called a dilation and the "point" is called the dilation centre..
What is data compression with example?
Data compression can dramatically decrease the amount of storage a file takes up.
For example, in a 2:1 compression ratio, a 20 megabyte (MB) file takes up 10 MB of space.
As a result of compression, administrators spend less money and less time on storage..
What is meant by data compression?
Data compression is the process of encoding, restructuring or otherwise modifying data in order to reduce its size.
Fundamentally, it involves re-encoding information using fewer bits than the original representation..
