Computer systems originate with hardware. But, they will influence software development, which in turn influences how hardware has to be developed to make better use of the software. This circular cycle has made hardware and software more responsive to development and more responsive to user needs. In addition, computer systems now work with networks, and there is an impact there as well. This Bright Hub Guide to Computer Systems offers users and curious onlookers an opportunity to look at the different aspects of a computer system, the new hardware and devices, and how they interact with one another.
