Any bidirectional communication channel or link between two or more computers fits into this category. This can be Ethernet port (wired or wireless) directly connected between two machines or associated switch or router which allows more connections to same network. Similarly other wired or wireless serial connections (like serial ports, USB, Bluetooth, Infrared) between computers can also send and receive data instructions and information between computers.
Actually the answer to this question is communication device, stated in the book: Microsoft Office 2007 Introductory Concepts and Techniques
All computers currently available have similar components and functions. The obvious component is the System Box. This is most obvious in Desktop Computers. The system box used to be called the CPU - wrongly considering the confusion that caused. What the system box contains are things like a power suplly to power everything, the memory to do the work required and also to store the answers obtained fro the work, and the heart or mircroprocessor to actually do everyhing needed. The second component is the Screen to show you what information you are giving the computer, any message the computer needs to tell you, and the results the computer has come up with. The thrid component is the Keyboard to enter information into the computer, give the computer instructions on what to do with the information, and were to send the results to.
