Customize
In general, customize describes anything made to do a specific task or designed according to certain specifications. For example, if you buy an OEM (Original Equipment Manufacturer) computer from a store, it's not generally customizable. However, if you buy a custom-built PC, it would have the hardware tailored to meet your needs. Additionally, if you run a business, it may use custom software designed to meet your company's needs. Finally, adjusting a computer's settings is also considered a form of customization (e.g., overclocking its processor).
