Asymmetric is the opposite of symmetric

Symmetric means that the design of the image is balanced and both sides are equal. An asymmetric image is when the design does not repeat itself so if you fold it in half the designs will not meet in the same areas.

what is the difference between commutative and symmetric properties

A symmetric multiprocessing (SMP) system is one in which each processor runs an identical copy of the operating system on each processor. In an asymmetric multiprocessing, system, each processor is assigned a specific tasks. An example of this would be a master- slave relationship between one processor and “the rest”.

Symmetric cryptography uses the same secret (private) key to encrypt and decrypt its data whereas asymmetric uses both a public and private key. Symmetric requires that the secret key be known by the party encrypting the data and the party decrypting the data. Asymmetric allows for distribution of your public key to anyone with which they can encrypt the data they want to send securely and then it can only be decoded by the person having the private key. This eliminates the need of having to give someone the secret key (as with symmetric encryption) and risk having it compromised. The issue with asymmetric is that it is about 1000 times slower than symmetric encryption which makes it impractical when trying to encrypt large amounts of data. Also to get the same security strength as symmetric, asymmetric must use strong a stronger key than symmetric. If you do a quick search on the differences between symmetric and asymmetric you can find many more explanations. This just a quick overview.

1. RSA comes under Asymmetric and DES comes under Symmetric 2. RSA is more secure than DES.

Symmetric encryption requires one key available to both parties. Asymmetric encryption uses two keys, one encryption key available publicly and one decryption key available only to the recipient.

symmetric compressionA data compression technique that takes about the same amount of time to compress as it does to decompress.asymmetric compressionA data compression technique that typically takes more time to compress than it does to decompress. Some asymmetric compression methods take longer to decompress, which would be suited for backup files that are constantly being compressed and rarely decompressed.

Symmetric encryption is a single shared, private key between communicating nodes. There is only 1 key involved. Public Key encryption (or asymmetric encryption) requires a pair of keys; a public and a private key for exchanging data in a secure manner.
