What is peripheral and interface?
Peripheral It means various components or devices those are connected to CPU. Thus PHERIPHERAL INTERFACING is a kind of interaction between processor and external or peripheral devices. To interface physically, a component or mediator between I/O device and processor is used which is called I/O module.

What is computer and computer peripherals?
A computer peripheral is any external device that provides input and output for the computer. For example, a keyboard and mouse are input peripherals, while a monitor and printer are output peripherals. Some peripherals, such as external hard drives, provide both input and output for the computer.
What are the computer peripherals of CAD?
Input devices include keyboard, mouse, scanner, digital camera and drawing tablet. Processors include CPU (Central Processing Unit – ie the brains of the computer), operating system, memory and CAD software. Output devices include monitor, printer, plotter, cutter and CNC machines.
How I O devices are interfaced with computer?
The method that is used to transfer information between internal storage and external I/O devices is known as I/O interface. The CPU is interfaced using special communication links by the peripherals connected to any computer system.
How memory chips and I O devices are interfaced to a microprocessor?
The corresponding memory chip or I/O device is selected by a decoding circuit. Memory requires some signals to read from and write to registers and microprocessor transmits some signals for reading or writing data. The interfacing process includes matching the memory requirements with the microprocessor signals.
What do you mean by peripheral?
1 : of, relating to, involving, forming, or located near a periphery or surface part (as of the body) 2 : of, relating to, affecting, or being part of the peripheral nervous system peripheral nerves. 3 : of, relating to, or being the outer part of the visual field good peripheral vision.
What are the roles of computer peripherals?
Without peripherals, your communication with your computer would be far more limited. Peripherals are the devices external to your computer that take in information, allow the computer to put out information in visible and audible form, and perform other important tasks.
What are the two categories of computer hardware?
The Four Categories of Computer Hardware
- Input devices: For raw data input.
- Processing devices: To process raw data instructions into information.
- Output devices: To disseminate data and information.
- Storage devices: For data and information retention.
