the topic is comparing 3 computers and writing about the purpose software and hardware of the computer

Computers Comparison Computers are purchased for specific purposes and uses. The buyer, therefore, has a purpose in mind when sourcing for a computer and will go for a computer that serves the intended purpose. However, the buyer must also consider the price of the computer to ensure that he or she can afford the said computer. The task of exploring the best computer to deliver the expected services while still being affordable to the user is always uphill. Most people end up overspending on computers or getting one that does not fully serve their purpose due to budgetary constraints. This paper will look into three different computers and compare their purposes, software and hardware as well as the prices. The three computers are a gaming computer, a computer for graphic design and a normal college computer. The budgetary range for the three computers is $800 to $2000. This paper is guided by the thesis that with the budgetary range of between $800 and $2000, one can make purchases of three credible computers that will serve the gaming, graphics and collegial purposes. The paper will explore each of the selected computers separately.
