deciding which method is the best for data input and output (I/O). Users communicate with computers in an information system through input and output devices. The user enters input data into the system through input devices and receives output information through output devices. It is extremely important for businesses today to select the right input and output hardware for its information system. Some common areas of concern for input and output devices in businesses today are printed questionnaires

Understand the selection‚ hardware and software requirements of a PLC P1 There are 3 types of PLC‚ unitary‚ modular and rack-mounted. A unitary PLC is a stand alone unity‚ it has no room for expansion and works on its own. They are useful for automating activities such as stress testing. For example the stress testing of a hoist‚ instead of paying someone to manually control the hoists up and down movement leaving time in between each motion a PLC could be used instead. It could be set up to
