Even though both data compression and encryption are methods that transform data in to a different format, the golas tried to achieve by them are different. Data compression is done with the intension of decreasing the size of data, while encryption is done to keep the data secret from third parties. Encrypted data cannot be decrypted easily. It requires the possession of a special piece of information called a key. Uncompressing compressed data do not require such special knowledge (such as a key), but it might require some special hardware depending on the data type.

Is it most encryption programs compress files?

No. Encryption is not compression. Compression occurs before (and possibly again after) encryption when outgoing, and reversed when incoming. In all probability, the encrypted file is likely to be a few byes larger than the original source data, but since compression is applied first, the overall transmission is likely to be smaller than the source.


Is there a way algorithm to encrypt more numbers in one number and can decrypt?

Yes, there are several algorithms for data compression, that is, store data in less space than it usually needs. However, not all data can be encrypted. Encryption basically takes advantage of some sort of repetition in data; once all repetition has been eliminated, data can be encrypted no more.Yes, there are several algorithms for data compression, that is, store data in less space than it usually needs.

What are example files of data encoding?

Not to be flippant, but every file is an example of data encoding. Before data can be stored in computer memory or in a disk file, it first has to be digitally encoded in binary. The binary encodings can then be further encoded using encryption or compression.


Is compression a form of encryption?

No, it's not but some compressed files can be encrypted.

What are the three primary functions of the presentation layer?

Coding and conversion of Application layer data to ensure that data from the source device can be interpreted by the appropriate application on the destination device. Compression of the data in a manner that can be decompressed by the destination device. Encryption of the data for transmission and the decryption of data upon receipt by the destination.


What does disk encryption protect you from?

Disk encryption protects the data on a hard drive from being read by someone that isn't authorized. Disk encryption works by converting the information on the drive to unreadable data.
