The correct answer is: C. define your computing needs.
Before buying a PC system, you need to define your computing needs. What will you use the PC for? Will you be using it for gaming, video editing, or just basic tasks like browsing the internet and checking email? Once you know what you need the PC for, you can start shopping for the right components.
Option A is incorrect because you should not shop for application programs before you know what you need the PC for. You might end up buying programs that you don’t need or that are not compatible with your PC.
Option B is incorrect because you should not identify your hardware components before you know what you need the PC for. You might end up buying components that are not powerful enough for your needs or that are not compatible with each other.
Option D is incorrect because you should not call for tenders before you know what you need the PC for. You might end up getting quotes from companies that are not qualified to build your PC or that are not offering a good price.
Option E is incorrect because it is not a valid option.
