Whats the longest computer cable I can use?
In general, you don’t need to worry too much about this, whether for a monitor screen, or for devices that use the serial, parallel, USB, SCSI or FireWire ports, since it’s rare for anyone to solder up their own. Be guided by what suppliers have on offer most budget cable ranges will include a couple of standard lengths, but expect to pay a premium if you want a particularly high-quality one which avoids problems over long cable runs. While it’s easy to source extender cables for mice and keyboards, try to avoid joining cables together when using high-speed digital protocols like SCSI. These benefit from high-quality cabling throughout, with cable lengths kept to the shortest possible.
