BY MADUMELU KELVIN 19/SCI01/097 1. An input device in simple words is one that helps the computer get the data from the user and enters it in the computing system. An output device in simple words is the one that helps the computer to display the data and results after the process completes. 2. The main type of input devices includes a Keyboard, Image Scanner, Microphone. Pointing device. Graphics tablet. Joystick. Light pen. Mouse. Optical. Pointing stick. Touchpad. Touchscreen. Trackball. Webcam. Softcam and Refreshable braille display. 3. The main type of output devices includes Monitor. (LED, LCD, CRT, etc.), Printers of all kinds, Plotters, Projector, LCD Projection Panels, Computer Output Microfilm (COM), Speaker and Head Phone. 4. An input device takes the data from the user and then sends it to the processor for further steps, whereas an output device takes the data from the processor after the actions complete and then sends it back to the user. 5. Input devices are more complicated as they have complex coding the ensures that the user can interact with the computer correctly whereas the output devices are simpler for the user since they only see the results and do not have to learn the processes Examples of input devices; Keyboard, Image Scanner, Microphone, Pointing device, Graphics tablet, Joystick mouse. Examples of output devices; Monitor, Printers of all kinds, Plotters, Projector, LCD Projection Panels, Computer Output Microfilm, Speakers. .

Hardware Components of a Computer System
Hardware Components of a Computer Hardware Components of a computer refers to the collection of physical parts of a computer system that we can touch or feel. This includes the computer case, monitor, keyboard, and mouse. It also includes all the parts inside the computer case, such as the hard disk drive, motherboard, video card, and many others. The hardware components of a computer or personal computer is categorized into 4 primary categories: - a. System Unit b. Display Device c. Input Devices d. External Devices a. System Unit A System Unit is the main component of a personal computer, which houses the other devices necessary for the computer to function. It is comprised of a chassis and the internal components of a personal computer such as the system board (mother board), the microprocessor, memory modules, disk drives, adapter cards, the power supply, a fan or other cooling device and ports for connecting external components such as monitors, keyboards, mice, and other devices. System Unit Components b. Display Devices A display device is a personal computer component and is an output device that enables user to view the text and graphical data associated with a computer program. Display devices commonly connect to the system unit via a cable, and they have controls to adjust the settings for the device. They vary in size and shape, as well as the technology used. 1 Display Device c. Input Devices An input device is a personal computer component that enables users to enter data or instructions into a computer. The most common input devices are keyboards and computer mice.

Remote Duel Set up Guide Webcam Gooseneck Smartphone Holder Method
Remote Duel Set Up Guide Remote Duel Set up Guide There are many options for putting together a Remote Duel set up; we’ve listed a handful below using the devices you already have or are relatively inexpensive. This guide will also give some suggestions on how to set up one’s field and video frame for Remote Dueling. Webcam The simplest option is to use a USB webcam designed for computers or the webcam built into the computer. Most programs will recognize the application as a webcam and can be used to record the field. Gooseneck Smartphone Holder Method A “Gooseneck Smartphone Holder” is an extendible arm that attaches to a table via a mount and depending on the model of the device, holds a smartphone at the end of the arm. ©2020 Studio Dice/SHUEISHA, TV TOKYO, KONAMI Page | 1 Remote Duel Set Up Guide Example of a typical set up. Be sure to follow the manufacturer’s instructions correctly If the arm is obstructing too much of the monitor, we recommend moving the monitor to a safe position ©2020 Studio Dice/SHUEISHA, TV TOKYO, KONAMI Page | 2 Remote Duel Set Up Guide Tripod and Smartphone Mount Method Tripods can be used to place the smartphone above the field. Larger tripods can be placed on the floor, and smaller tripods can be placed on the table. It is recommended to get a tripod that can swivel and tilt to quickly adjust the image on the screen. Most tripods do not include a smartphone‐mount, so it may be necessary to obtain a tripod‐compatible smartphone‐mount.
