Pentium is a microprocessor made by Intel. It does not in itself measure anything, but applications can be installed on the OS for different types of measurement.
Pentium Duo Quad, Pentium core duo, Pentium D, Xeon, Itanium, Pentium M, Pentium 4, Celeron, Pentium 3, Pentium 2, Pentium Pro, 486, 386, 286.
There are version of Intel Pentium one through four as well as Intel Pentium Pro, Intel Pentium D, Intel Pentium M, Pentium (2009), and Pentium Duel Core.
No. The Pentium predates the Pentium D by more than a decade.

pentium 4 more faster
As a whole, the Pentium 4 has a higher maximum performance than a Pentium III. The Pentium III performs the same as or better than Pentium 4 at the same clock speed, but the Pentium 4 has a higher max clock speed (which the Pentium 4 was designed for).
Pentium 4 with HT technology runs at the highest speed.
Pentium 4 sockets were sockets numbers Socket 423 for early Pentium 4's. Then socket 478 for Pentium 4, Pentium 4 Extreme Edition and Celeron and socket T (LGA 775) for Pentium 4, Pentium D dual core, Celeron D and Pentium Extreme Edition.

There is no "Pentium R" processor. Knowing this, the biggest difference is that the Pentium III exists and the other does not.
There is no such thing as a Pentium 5. That would be a type of processor, except that Intel stopped naming them Pentium before the Pentium 5 came out.
The Pentium D is basically a dual-cored version of the Pentium 4. It is nowhere near as efficient or powerful as a Core 2 Duo, and it actually generates slightly more heat than a Pentium 4.
