Most commonly PS/2, USB, USB 2.0
This is called a "bus mouse" and is the precursor to PS2 technology. In the 1980s IBM compatible computers did not have a built in interface for a mouse. At the time many mouses used a serial connection (COM port). The bus mouse interface was developed by Microsoft so that the mouse would have its own dedicated interface. It was soon rendered obsolete when IBM released its next generation of PC's with the PS2 interface for keyboard and mouse.
A CD drive can interface with a mother board using an EIDE, SATA or SCSI interface.
The keyboard cable is orange with less prongs and the mouse cable is green with more prongs.
There are many ways to link 2 computers together. You can use a parallel cable, a crossover cable via the network interface card, run remote desktop over the internet, going through a router, special USB interface connection, programs like PCanywhere and using wireless connection. The best method depends on what you are wanting the link between the computers to do and what hardware you have to work with.
The mouse does not change. It remains a pointing and interface device.
There is not a cable that can extend the range of a wireless mouse.
MIDI is an acronym which stands for Musical Instrument Digital Interface. It is a set of programming rules used to govern the connection and interface of musical instruments with computers. Musical Instrument Digital Interface on a piano means MIDI u can connect it to a computer thru a midi interface or u can connect 2 pianos with a midi cable and perform what u want from the both pianos, like IN,OUT and THRU option.
Cable not so much but you have to be careful with the internet
User Interface Devices
To establish a USB MIDI connection between your devices, you will need a USB MIDI interface cable. Connect one end of the cable to the USB port on your computer and the other end to the MIDI port on your MIDI device. Install any necessary drivers or software, then configure your devices to recognize the MIDI connection.
One can buy a MIDI to USB interface cable from Amazon for $4.09. One can also purchase this type of cable from ebay, Cable Depot, Maplin, Roland and Staples.
A network interface card (NIC) would allow that.
