Input and output devices
Input devices allow information to enter a computer and include keyboards, mice, scanners, microphones, and cameras. Keyboards and mice are common human interface devices that allow text and cursor control entry. Scanners can digitize text and images while microphones and cameras convert sound and visual recordings. Output devices display or print information from computers using monitors, printers, speakers, and projectors. Monitors provide a soft copy visual output while printers produce a hard copy. Combination devices like fax machines and terminals include both input and output capabilities.
Computer output devices
An output device is any peripheral that receives data from a computer, usually for display, projection, or physical reproduction. For example, the image shows an inkjet printer, an output device that can make a hard copy of any information shown on your monitor.

Hardware & Input/Output (I/O) Devices
Hardware devices that are used to input and output data to a computer are called I/O devices. Input devices capture information from the external environment and convert it into a format that can be processed by the computer. Examples include keyboards, mice, scanners, microphones, and webcams. Output devices take the processed data from the computer and present it to the user. Common output devices are monitors, printers, speakers and plotters. Monitors display soft copy output while printers provide hard copy printouts.
Input output hardware
Input and output devices allow people to enter data into computers and receive processed results. Key input devices include keyboards, pointing devices like mice, scanners, and microphones. Output is delivered through permanent devices like printers and plotters that provide hard copies, and temporary devices like monitors and speech synthesizers that offer immediate visual and audio output. Some action output devices control machines and robotics.

It interfaces with the operating system and hardware to provide functionality to end users.
Input and output devices.pdf
peripheral device, also known as peripheral, computer peripheral, input-output device, or input/output device, any of various devices (including sensors) used to enter information and instructions into a computer for storage or processing and to deliver the processed data to a human operator or, in some cases, a machine controlled by the computer. Such devices make up the peripheral equipment of modern digital computer systems.
Peripherals are commonly divided into three kinds: input devices, output devices, and storage devices (which partake of the characteristics of the first two). An input device converts incoming data and instructions into a pattern of electrical signals in binary code that are comprehensible to a digital computer. An output device reverses the process, translating the digitized signals into a form intelligible to the user. At one time punched-card and paper-tape readers were extensively used for inputting, but these have now been supplanted by more efficient devices.

Gps Introduction
GPS uses satellites to determine the location of receivers on Earth. It works by triangulating the user's position based on signals from at least 3 satellites. Accuracy is typically within 10-20 meters but can be improved to the centimeter level with additional equipment. GPS accuracy can be enhanced through systems like WAAS and DGPS which use additional satellites and ground stations to correct for errors in the GPS signals. Factors like obstructions, weather, and receiver quality can introduce errors of around 10 meters in the calculated position.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
