Block Cipher Clarification

I am creating my study notes and wanted to make sure I understand this concept correctly.

Pardon the simplified definition but I am trying to put this in my own words.

Block Ciphers encrypt data in "blocks"/chunks. The size of the block depends on the algorithm used. For example, DES has a block size of 64 bit. Data is encrypted in 64 bit blocks using a 56 bit key 16 times (rounds).

Thanks!
