Clear["Global`*"] clears things in the Global context. Clear out
other contexts, reset the history stack etc. as would occur by
quitting the kernel. For example:

In[1]:= a = 3;

In[2]:= Clear["Global`*"]

In[3]:= b = 3;

In[4]:= Quit[]

In[1]:= a = 4;

Notice the count of input cells increases after using Clear but
resets to 1 after using Quit

Yes, Quit[]. See above.

It might be worth mentioning if your goal is to restore some
previous state of a session, the CleanSlate package offers more flexibility.
