Input devices are used to capture data at the earliest possible point in the workflow, so that the data are accurate and readily available for processing.
The latest input devices include: Point of sale, Touch pad, Smart card and Touch screen. The latest output devices include: Terminals, Plotters
Input Devices: - keyboard - touch screen - key pad - mouse Output Devices: - receipt printer - monitor
Keyboard- used to input text into the computer Mouse- used to point click and drag items.
Well the point for sale and advantages is pretty obvious and simple both for the buyer and seller. If you are a buyer you don't have to pay much and for a seller they get more customers.
POS terminal means Point Of Sale terminal.keyboardbarcode scanner/reader
Bar-code scanner & Credit/debit card reader.
Here are the input and output devices in a supermarket and their roles:Cameras - These are input devices for the store security system. Their security office has computers, I/O storage devices (often hard drives), and monitors for output devices so their loss management team can watch suspicious customers.Checkout lights - While not a computer component, these are output devices that let the customer know if the register is open or closed. If they are flashing, then that signals that a manager is needed, or that the cashier has left to get the manager or do a price check.Keypads - These are input devices used for the cashier and/or the customer to enter data. For the cashier or manager, it is to enter price overrides and to enter prices or SKU codes of unmarked merchandise. For the customer, it is for entering their pin number.Loss management sensors - These are primarily input devices in that they use RF signals to detect if there is unpaid merchandise. But they are also output devices when a detection is made, since they sound alarms and flash lights to alert the possibility of theft.Price scanner - This is an input device that reads the UPC codes so the prices can be determined.Receipt printer - This is an output device that prints the receipts for the customers. This could be a part of a cash register or a separate device that is attached to a point of sale system or computer.Scales - These are primarily input devices in that they input data from the weight of the products. They are also used as security devices in self-check registers. They can also be output devices if they display the weight of the product.Video terminals - These are output devices that are used to show the cashier and the customer the prices and to allow the cashier to operate the system. There are also video terminals in the security office.
The main purpose of input devices is to allow users to input data, commands, and instructions into a computer system. Input devices are used to interact with and control computer systems. They allow users to provide input in various forms, such as text, images, sound, and motion, among others. The input devices translate the user's input into a digital format that the computer can process and interpret. Examples of common input devices include: Keyboard: used to input text and commands Mouse: used to navigate and select items on the screen Touchpad: used as an alternative to a mouse on laptops and other mobile devices Touchscreen: used to interact with graphical user interfaces (GUIs) through touch Scanner: used to input images and text into digital format Microphone: used to input sound and voice commands Camera: used to input images and video Joystick: used to control games and simulations Gamepad: used to control games on consoles and PCs Motion sensor: used to input motion-based commands and gestures Overall, input devices are essential for enabling users to interact with and control computer systems, and they are critical for a wide range of applications, including communication, entertainment, education, and business.
A bar code reader is an input Device. Although they sometimes output a visible light, the purpose is to gather data from a printed code and input that data into your system (computer, Point of Sale, etc.)
