On the older IDE hard drive interface there is a 40-pin connector. The cable attaching to this connector can have 40 wires or 80 wires. The 80 wire version is superior and has a faster data transfer rate because it _____.1. Has additional signal-carrying conductors. 2.Uses the extra 40 wires as shields to reduce crosstalk.3. It is newer and contains silver in the conductors.4. The smaller wires present less impedance to current flow
