The original base units were the metre, kilogram and second. This was extended to include the ampere, candela, kelvin and mole.
The International System of Units (SI) is based on seven base units: the meter for length, kilogram for mass, second for time, ampere for electric current, kelvin for temperature, mole for amount of substance, and candela for luminous intensity. These base units are used to derive other units for quantities such as area, volume, and velocity.
The two most common systems of units are cgs and SI systems
This is one question where no clear "yes" or "no" can be given. Metric system is a general term for several systems of units. SI is one of them, based (among other units) on meter, kilogram, second. It is in the subcategory of MKS (thus called for those three base units). Older systems (also labelled "metric systems) were often CGS, in other words, the base units included centimeter, gram, and second.
There are many systems. A system is a collection of units which are used together. The two commonest are the SI units, based on the metric system, and imperial units (feet, pounds etc.)
"SI", from the French "Systeme Internationale".
si units are based on the metric system system international (French) international system (English)
SI is a base 10 standardized system
10. SI units are based on the decimal system. For many purposes they can be seen as based on a system of 1000.
"si" stands for the International System of Units, which is the modern form of the metric system. It is based on seven base units, one of which is the meter for length.
The SI system is based on multiples (and divisions) of ten. There are seven base units, all others are derived from these.
The SI units are rationally defined, universal, based on a decimal system.

Not really. The second is one of the SI system's seven BASE (not 'basic') units.
Energy is measured in Joules.
Yes, it is recommended because the SI-units are based on the metric system.
