It's important to buy a business computer rather than a personal computer because

its important to keep the two separated to that one does not share information that  should not have been shared also so that you can work at work and have personal time at home and so that you don't get distracted so one is only for work the other is everything else.

It's important to buy a business computer rather than a personal computer because: a personal computer is usually only equipped to perform common tasks of modern computing, such as surfing the Internet, studying, writing texts and performing other office or educational work, such as editing texts and databases, other than leisure activities, such as listen to music, watch videos, play.

On the other hand, business computers allow the application of different types of programs that can help keep track files, documents, agendas and deadlines, also allow to organize all the neccesary information in a very accessible way, having a large data storage capabilities, which leads to better management of time and productivity.

the correct answer would be b, when, queen, calder hall and london.

explanation:

we always capitalize words when a paragraph or sentence is starting, when an important name is used, when a place is being written, or simply when a noun is used, etc. so in this sentence, sentence is starting from 'when', so it will be written in capital letters. secondly, queen is considered to be an important person, so it will also be written in capital letter. next, the name of the town is mentioned, i-e calder hall, which will also be written in capital letters. in the last,   city name is being used, 'london', which will also be written in capital letters. so option b is the most appropriate one.
