analog and digital

from my reading about the difference between analog and digital data is analog data refer  to the other storage methods, for examples, records and cassette tapes are forms of analog data storage.Then, digital data refers to information stored as zero and one and represent in a number of the ways.For example, CD and DVD player.

2) lossy and losseless are two categories of compression but,both of it have the same aim.

lossy refer to the sometimes some loss of quality is acceptable. For examples the methods includes DCT(discreet cosine transform)

lossless are used to make a file a smaller size but without losing any of information and always get back to the original file.

1)  21st century learning includes teaching approaches to incorporate content skills where students are more innovative,creative and independent in solving problems and can cope with any challenge to succeed and make student more intellectually. There is a few of the characteristics of 21st century learner that i think is very useful to know and will can apply it in learner.
