What is blob?

Hello!
I need some clarification and examples about “blob” and it’s usage in machine learning context. According to quora,
https://www.quora.com/What-is-a-blob-in-Caffes-deep-learning-library
But I miss some examples for understanding.
http://caffe.berkeleyvision.org/tutorial/net_layer_blob.html
Official documentation helps in understanding, but I can’t connect it with synonyms from fast.ai, for full understanding.
If someone can explain in in different words it might be very helpful.

It’s just a bunch of data. In other ML frameworks this is generally called a tensor, or a multi-dimensional array.

Thank you so much! This is the answer I have been looking for
