CONFIG.SYS
CONFIG.SYS is the primary configuration file for the DOS and OS/2 operating systems. It is a special ASCII text file that contains user-accessible setup or configuration directives evaluated by the operating system during boot. CONFIG.SYS was introduced with DOS 2.0.
Usage
The directives in this file configure DOS for use with devices and applications in the system. The CONFIG.SYS directives also set up the memory managers in the system. After processing the CONFIG.SYS file, DOS proceeds to load and execute the command shell specified in the SHELL line of CONFIG.SYS, or COMMAND.COM if there is no such line. The command shell in turn is responsible for processing the AUTOEXEC.BAT file.
CONFIG.SYS is composed mostly of name=value directives which look like variable assignments. In fact, these will either define some tunable parameters often resulting in reservation of memory, or load files, mostly device drivers and TSRs, into memory.
In DOS, CONFIG.SYS is located in the root directory of the drive from which the system was booted.

Thunder
Thunder is the sound caused by lightning. Depending on the distance and nature of the lightning, thunder can range from a sharp, loud crack to a long, low rumble (brontide). The sudden increase in pressure and temperature from lightning produces rapid expansion of the air surrounding and within a bolt of lightning. In turn, this expansion of air creates a sonic shock wave, similar to a sonic boom, which produces the sound of thunder, often referred to as a clap, crack, or peal of thunder.
Cause
The cause of thunder has been the subject of centuries of speculation and scientific inquiry. The first recorded theory is attributed to the Greek philosopher Aristotle in the fourth century BC, and an early speculation was that it was caused by the collision of clouds. Subsequently, numerous other theories were proposed. By the mid-19th century, the accepted theory was that lightning produced a vacuum.
In the 20th century a consensus evolved that thunder must begin with a shock wave in the air due to the sudden thermal expansion of the plasma in the lightning channel. The temperature inside the lightning channel, measured by spectral analysis, varies during its 50 μs existence, rising sharply from an initial temperature of about 20,000 K to about 30,000 K, then dropping away gradually to about 10,000 K. The average is about 20,400 K (20,100 °C; 36,300 °F). This heating causes a rapid outward expansion, impacting the surrounding cooler air at a speed faster than sound would otherwise travel. The resultant outward-moving pulse is a shock wave, similar in principle to the shock wave formed by an explosion, or at the front of a supersonic aircraft.
Thunder (ship)
FV Thunder was an outlaw fishing vessel sunk in 2015. The ship was built in 1969 in Norway and has gone by many names, including: Vesturvón, Arctic Ranger, Rubin, Typhoon I, Kuko, and Wuhan N4. The ship was last registered in Lagos, Nigeria; however, the ship was officially de-listed by Nigeria a week before it sank.
At the time of its sinking, the crew consisted of 30 Indonesians and 10 officers from Spain, Chile, and Portugal, who were turned over to the authorities in São Tomé and Príncipe. The officers of the crew were later tried and convicted of several illegal fishing offences. The captain, Luis Alfonso Rubio Cataldo of Chile, was given a three year sentence. The ship's chief engineer, Agustín Dosil Rey of Spain, was given a two year and nine month sentence. The ship's second mechanic, Luis Miguel Pérez Fernández of Spain, was given a two year and eight month sentence. Together, they were fined a total of over $17 million.Interpol believes that the vessel was part of a fleet of six operating through shell corporations under Vidal Armadores, a company based in Spain.
Thunder (Jessie J song)
"Thunder" is a song by English recording artist Jessie J. It was written by Jessie J, Claude Kelly, Benjamin Levin, Tor Erik Hermansen and Mikkel Storleer Eriksen for her second studio album Alive (2013), while production was helmed by StarGate and Benny Blanco.
Background
"Thunder" was written by Jessie J, Mikkel S. Eriksen, Tor Erik Hermansen, Claude Kelly and Benny Blanco. It was produced by Eriksen and Hermansen, credited under their production name StarGate, along with Blanco. Jessie's vocals were recorded by Chris Sclafani, Joel Peters, and Justin Pancionendon, with Mark "Exit" Goodchild serving as its engineer. Kelly provided additional vocals on the song. "Thunder" was mixed by Phil Tan and assistants Daniela Rivera and Phil Seaford. Eriksen and Hermansen recorded the song's instrumentation, and Tim Blacksmith and Danny D. were assigned as its executive producers. Andrew "McMuffin" Luftman and Scott "Yarmov" Yarmovsky were credited as production coordinators on the song.
