Where the rest of 100MB file is being kept when it is compressed into 80MB zip file?
In: Engineering
Imagine I have the word Mississippi. File compression is like taking the word Mississippi and converting it to (M)(iss)(iss)(ippi). Then, label each unique blob; (M) is 1, (iss) is 2, and (ippi) is 3.
Once each blob of data is labeled, you can convert Mississippi to 1223. Much smaller!
The zip file basically contains a condensation of information and an index table of each piece of data.
Same information, but rearranged and simplified, reducing the amount of memory needed to convey it.
Instead of spelling out the whole word, I’m providing instructions on how to recreate the word, and the instructions are smaller than the original word themselves.
