AMPLIFIER:
The circuit which produces the output as twice or increase than the input signal than the circuit is called amplifier.    
                     (or)
The circuit which produces the output as higher signal strength than the input signal strength than the circuit is called as amplifier.

From the circuit,the circuit consists of input between +1v to -1v.But it produces the output between 4v to 10v.so,the circuit is proved it is an amplifier.The circuit diagram consists of single amplifier(transistor) ,therefore it is called as single stage amplifier.

Try to reduce the input voltage. That will make the output not to enter on saturation.

First, you're not really going to see the actual values on the output until it's under a load. Common Emitters tend to like a fairy high impedance load. Next, it's not so much a 1V signal that's the problem, it's the biasing. Or lack thereof. Everything is just default values of 1k and 1uF. With that said though, with a 1V input, and only a 10V supply, there's only room for a maxiumum gain of about 14db (5v/v), IF the output can swing fully from rail to rail. As it's bias right now, it can't swing from rail to rail, and that bypass cap allows for too much AC gain, so the output clips.
