Input devices are used to enter data from outside world into primary storage & output devices supply the result of processing from primary storage to users.. Input device is any peripheral (piece of computer h/w equipment) used to provide data & control signals to an information processing system. Input/output devices make up the h/w interface between a computer .. 2. Output – Four Types. video. audio. text. graphics. Output Device. An . output device. accepts processed data from the computer and presents the results to the user.. Display Devices. The most common form of output device is a . By Humphrey Kumwembe. OBJECTIVES. After completing this lesson, you should be able to:. Define input and differentiate among a program, command and user response.. Identify input device categories.. Define output and describe the types of output.. streams. A simple input stream accepts typed data from a keyboard. A simple output stream writes data to the terminal. Standard Input/Output Streams. A . stream. is a sequence of characters. Streams . Difference between PNP and NPN sensors. PNP.  sensors are sometimes called “. sourcing.  sensors” because they source positive power to the output. ..  . NPN. sensors are sometime called “. Input and Output By: Billy & Ashley What is it? Input/output is a communication system between an information processing system, such as a computer. Connects systems to the outside world Input/output is the name given to the device depending on its role MCOTS-C-48-12-HPHalf-brickProduct MCOTS-C-48-12-HPPhone 1-888-567-9596wwwsynqorcomDoc 005-0005342 Rev G07/24/20Page 1The MilQor series of Mil-COTS DC-DC converters brings SynQor146s field proven hig
