Connectors for integrated peripherals refer to the physical ports on a motherboard that allow for the connection of various external devices such as USB drives, keyboards, mice, and monitors. These connectors are typically located on the motherboard itself and are essential for expanding the functionality of a computer system. Examples of connectors for integrated peripherals include USB ports, HDMI ports, audio jacks, and Ethernet ports.
Most cases have the motherboard ports in the back that way you can hide all the cables and keep them away from alot of activity that may disconnect them.I have not seen a PC with front motherboard ports. But i think its better to leave those ports where they are :)
The port is an external connection device on the computer which is used to connect different peripherals. Concretely it is a socket (and the corresponding plug) that enables an external device (peripheral) to be attached to a computer (usually to a motherboard or adapter card).
do you mean "motherboard I/O ports"? Eg. USB, PS/2, Serial, Parallel...
use a different harddrive not using SATA such as an external USB or IEE1394 or SCSI or replace your motherboard with one with more SATA ports (4 ports is standard minimum)
