Great question, it is always good to ask away and get rid of any doubts that you may be having.
Someone starting a computer repair business can gain a competitive edge in the town by offering both software and hardware repair. Some business offer either one or the other. While other big companies only offer repair for products that they own (Intel, AMD, dell, etc). Another way of getting an edge on competition is to offer computer related products such as graphic cards and motherboards. Most computer repair businesses do not do this.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
