A 555 timer basically consists of:
# A voltage divider circuit, # Two comparators, # An SR flip-flop, and # Two (bipolar) transistors: one NPN (discharge) and one PNP (reset),
as can be seen in its block diagram.
The voltage divider consists of three 5Kohm resistors, so that we get (1/3)Vcc and (2/3)Vcc; we use these voltages as references for the comparators.
The three 5K resistors, along with IC's main applications being in timer and multi-vibrator circuits, give it the name 555 timer.
because they really liked the number 99, so they decided to name it 555
It have three 5K internal resistors in it. Hence the name.

The 555 IC timer is typically measured in units of time, such as microseconds (ยตs), milliseconds (ms), or seconds (s). It can be used to generate precise timing intervals for various applications.
The 555 IC timer does not have a clock.
555 is an arbitrarily assigned part number for a general purpose programmable timer IC. The number itself has no special meaning.
556 is a dual version of 555 single timer.
The 555 is a timer, not a counter.

Invented in 1970 by Hans R. Camenzind who was an electronics engineer from Switzerland, the 555 timer was first produced by Signetics in 1971.
