Lag is a common word meaning to fail to keep up or to fall behind. In real-time applications, the term is used when the application fails to respond in a timely fashion to inputs. The most common use regards online gaming when the game doesn't respond in sync with the player's controls, usually due to a slow internet connection, server latency or overworked hardware.

Lag is also often used in reference to video games to describe to the delay (or latency) between an action by a player and the reaction of the game.

In distributed applications (such as MMORPGs), lag is often caused by communication latency, which is the time taken for a sent packet of data to be received at the other end. It includes the time to encode the packet for transmission and transmit it, the time for that data to traverse the network equipment between the nodes, and the time to receive and decode the data. This is also known as "one-way latency". A minimum bound on latency is determined by the distance between communicating devices and the speed at which the signal propagates in the circuits (typically 70–95% of the speed of light in vacuum). Actual latency is often much higher because of packet processing in networking equipment, and other traffic.

Lata Mangeshkar (born September 28, 1929) is a singer from India. She is one of the best-known and most respected playback singers in India. Mangeshkar's career started in 1942 and has spanned over six and a half decades.

Mangeshkar was featured in the Guinness Book of World Records from 1974 to 1991 for having made the most recordings in the world. The claim was that she had recorded approximately 25,000 solo, duet, and chorus-backed songs in 20 Indian languages between 1948 to 1974. Over the years, while several sources have supported this claim, others have raised concerns over its veracity, claiming that this number was highly exaggerated and that Mangeshkar's younger sister, Asha Bhosle, had more song recordings than she had. In 2011 Guinness officially acknowledged Bhosle as the most recorded artist in music history.
