A joule is a unit of energy. As an example, it is the work done when applying a force of 1 newton for a distance of 1 meter (that's the basic definition of the joule). It is also the energy consumed by a 1-watt device in one second (this follows from the definition of the watt), from a 100-watt device in 1/100 of a second, etc.
A joule is a unit of energy, so you will find joules wherever there is energy.
Liter is a non-example of joule. A joule is a unit of energy, while a liter is a unit of volume.
A millijoule is one-thousandth of a joule.The prefix milli- means a thousandth of whatever follows, as in millimeter and millivolt, for example.
Same as the unit for energy. For example, the SI unit is the joule.
A joule/coulomb is represented by the volt. Example: a 9v battery provides 9 joules of energy to every coulomb of charge that passes through it.

Joule is the real name.
A joule is simply a unit to measure energy. Examples of energy include gravitational potential energy, kinetic energy, sound energy, light energy, elastic energy, nuclear energy.
The joule is an SI unit!

James Joule's parents were Benjamin Joule and Alice Prescott. Benjamin Joule was a brewer and became the manager of a brewery in Salford, England. Alice Prescott was from a wealthy family in Manchester.
In SI, if a unit is too small or too big, either standard prefixes or scientific notation is used. Standard prefixes would be, for example, kilojoule (a thousand Joule), megajoule (a million Joule), gigagoule (a billion Joule) etc. But if you want to indicate the power output of the Sun for example, the numbers are so enormous that it doesn't make sense to use special prefixes; scientific notation is much clearer in this case (3.83 x 1026 Watt or Joules/second).
