Consider a DASH system for which there are N video versions (at N different rates and qualities) and N audio versions (at N diff

erent rates and qualities). Suppose we want to allow the player to choose at any time any of the N video versions and any of the N audio versions. a. If we create files so that the audio is mixed in with the video, so server sends only one media stream at given time, how many files will the server need to store (each a different URL)? b. If the server instead sends the audio and video streams separately and has the client synchronize the streams, how many files will the server need to store?

Answer: a) N² files. b) 2N files.

Explanation:

If an user can choose freely both the video and the audio quality, if they are stored separately, but the user can download any mix of them as a single file, the server must store one audio version for each video version, so it will need to store NxN = N² files.

If, instead, the server can send the audio and video streams separately, so the user can choose one of the N videos available, and one of the N audio versions, the server will need to store only N video files + N audio audio files, i.e. , 2 N files.

Answer:

Priming.

Explanation:

The brain is the centre of control for all animals. It coordinates the body system, breathing, beating of the heart, memory, gait, speech, sight etc.

Memory is stored in the brain ( the function of the cerebral cortex in the cerebrum). Two types of memory are the long term and the short term memory. The long term memory stores information permanently in the brain, while the short term holds the information for a while and either transfers it to the long term memory or the memory decays.

To retrieve a specific memory from the wide memory of the brain, it activates a strand that leads to the memory, this process is called priming.
