A computer network not only all allows the sharing of both hardware (Printer, Hard Drive, etc.) and software (files, folders, data, etc.) resources, but also enables the intercommunication between network nodes. Furthermore, a computer network consist of both front-end (Laptops, Desktops, Tablets, Printers, etc.) as well as bank-end (Switch, Hub, Router, Firewall, UPS, KVM, Blade Array, RAID, etc.) computer equipment. Most general computer users, although very familiar with front-end, are unfamiliar with with bank-end. This is ironic given that they interact with bank-end just as much as the front-end. Of course the more traditional name for back-end computer equipment is Network Hardware. For most general computer users their definition of Network Hardware would be a "Router" and Modem.
