I have learnt brief details of what computers are made of and I have come to know what are the thoughts that should require to buy a computer. Moreover I have come to know what are the benefits of buying the computer as well as the basic skills of using the computer. The factors that all should consider apart from the hardware specifications before buying the PC is to check if the computer has warranty or not. Also we should see the operating system it is using and we should see the brands of the motherboard. Hence, we can say that briefly looking at the components of the computer one can buy a reliable computer.
