Distinguish between Asymmetric and symmetric encryption?

Symmetric encryption uses the same key for both encryption and decryption, while Asymmetric encryption uses different keys for encryption and decryption.

Symmetric is usually much faster but the key needs to be transferred over an unencrypted channel.

Asymmetric on the other hand is more secure but slow. Hence, a hybrid approach should be preferred. Setting up a channel using asymmetric encryption and then sending the data using symmetric process.
