realized that it was an astable multivibrator. An Astable multivibrator switches between two states without stopping by using their output signal to recharge the input signal. This works because of a transistor or amplifier that amplifies the output signal and forwards the charge to the input. In most astable multivibrators there are two capacitors in between the input and output terminals, one is fully charged and the other is fully discharged, which allows voltage levels to be stepped up or down. As the

Jason Mitchell NT1110 Computer Structure & Logic Mod 2 Short Answer 4-10-15 I/O Devices I/O devices enable us to control the computer and display information in a variety of ways. In computing, input/output or I/O is the communication between a computer and the outside world, possibly a human or information processing systems. Inputs are the signals or data received by the system and outputs are the signals or data sent from it. The computer keyboard is used to enter text information

Index registers and floating pointarithmetic hardware became widespread. Machine-independent high levelprogramming languages such as ALGOL, COBOL and Fortran wereintroduced to simplify programming. I/O processors were introduced to supervise input-output operationsindependently of the CPU thus freeing the CPU from time-consuminghousekeeping functions. The CPU would send the I/O processor an initialinstruction to start operating and the I/O processor would then continueindependently of the CPU. When completed
