How to make this code more acceptable?

Question

code review

There are several classes that are stored on the components of a computer. I check everywhere what kind of component I insert into the computer. In the store, I check what component the player wants to buy. How to get rid of it?

The code

using UnityEngine;
using TMPro;

Answer 1

The classes Motherboard, Power, etc. allocate common behavior to the parent class (for example, Component) and also do the ShowInformation method with a Component type parameter.
CheckItem is similar.
