Which of the following is/are specialized peripheral I/O bus: Group of answer choicesUSBSCSISATAPCI

The specialized peripheral I/O buses from the given options are:

1. USB (Universal Serial Bus): This is a common interface that enables communication between devices and a host controller such as a personal computer. It connects peripheral devices like mice, keyboards, printers, media devices, external memory, and digital cameras.

2. SCSI (Small Computer System Interface): This is a set of standards for physically connecting and transferring data between computers and peripheral devices. It is commonly used for hard disk drives and tape drives, but it can connect a wide range of other devices, including scanners and CD drives.

3. SATA (Serial AT Attachment): This is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives, optical drives, and solid-state drives.

However, PCI (Peripheral Component Interconnect) is not a specialized peripheral I/O bus. It is a local computer bus for attaching hardware devices in a computer and is an abbreviation for Peripheral Component Interconnect. PCI is a standard for connecting peripherals to the motherboard inside the computer and was introduced by Intel in 1992.
