temp = (a==1) ? 1 : 999;
1 - b - Excel is a computer program, so it'd be Software
2 - a - Process of elimination, haven't heard of the term 'peopleware' before.
3 - d - A joystick accepts input from a user to interact with a computer. ex. Flight Simulators
4 - c - A monitor will display (or output) an image based on what is received from the computer.
