Real-time bidding refers to the buying and selling of online ad impressions through real-time auctions that occur in the time it takes a webpage to load. Those auctions are often facilitated by ad exchanges or supply-side platforms. Real-time bidding lets advertisers manage and optimize ads from multiple ad-networks by granting the user access to a multitude of different networks, allowing them to create and launch advertising campaigns, prioritize networks and allocate percentages of unsold inventory, known as backfill.

An Internet protocol standard that specifies a way for programs to manage the real-time transmission of multimedia data over either unicast or multicast network services. 

A table sequence is also an explicit set of genericity and orderliness, which can make computation of structured data more flexibly. Record sequence is the reference of table sequence. They are closely related and their usages are almost the same.

The maximum tolerable length of time that a computer, system, network, or application can be down after a failure or disaster occurs.
