Consider an 8086 CPU used with a suitable peripheral interface IC that is used in an application that utilizes a scanner that scans a barcode and sends the barcode information to the CPU. Evaluate the above application and justify with a suitable block diagram, and explanation as to how IO data gets suitably transferred from the scanner to the CPU.

A peripheral device is refereed to as an auxiliary device like a computer mouse or keyboard that connects to and work with the computer in the same way or pattern.

The CPU communicates with peripherals via the method called buses examples of such buses are USB, PCI.

Kindly find an attached block diagram on how IO data gets suitably transferred from the scanner to the CPU in the explanation section below.

Explanation:

Solution

The transfer of data from a CPU to a peripheral device is achieved or determined through a computer port.

In Computer terms, a port is referred to as the part of a computing device that is available for connection to peripherals such as output and input devices.

The computer ports has many functions for example, connection to a monitor, web cam speakers or other peripheral devices.

The CPU communicates with peripherals via the method called buses. some example of buses commonly known are the universal serial bus (USB) which is used mostly for external devices, the PCI (Peripheral component interconnect), Front side bus(It is a type of bus for connecting CPU and main memory)

A peripheral device is refereed to as an auxiliary device like a computer mouse or keyboard that connects to and work with the computer in the same way or pattern.
