Communications of the ACM

If you're one of the more than 1,000,000 scientists, practitioners, educators, or students who regularly read Communications of the ACM in print or online, you may have noticed that a new feature has recently been introduced on the magazine's Web site—video.

K.R. Chowdhary

It is human that we are hardwired to understand and retain spoken words better
Than the text material, and human retentivity for video
Is far superior to retention of spoken
Words. At the same time, the rate of absorption
Of vider with speech is far better
Than text read. In conclusion, learning
More in lesser time.

Of course video storage requires much larger
Space than text, also, wideo transmission consumes much larger
Bandwidth than text, but advancing technologies
And larger cheaper mass storage devices will
Over come this.
