This computer will act as the client or the workstation. Today's websites are a mix of text, sound and images so the contents of the websites might be heavy. Hence, more the speed of the CPU better will be the performance of Internet access. The computer should have at least 1 GB of RAM. The higher the size of the RAM, the better is the speed of your computer. The computer should have at least 1 GB of free hard disk space. But this must not be a problem because most of today's computers come with at least 500 GB hard disk space.
