IPOTimer ( Input , Process , Output , Transfer Function setup and Timer ) Bus and Mother board : 1. Parallel Port , 2. Serial Port , 3. ISA , 4. PCI , 5. USB , 6. Wireless , 7. IOT , 8 Cloud and Machine Learning by AI . the need for computer connectivity with integrated electronic machines continues to increase, not only with computers and printers but also with other external devices. Usually this connectivity is through an electronic communication device which we call an interface. There are many methods in electronics to connect 4th generation electronic machines with the host system connected to external devices using an interlock, namely each control signal transition will be data and analyzed at the opposite end of the interface. the interface works like a transistor system in analog circuits, namely electronic switches which are divided into 2 groups, namely data communication equipment and data terminal equipment. All electronic communication systems and their controls must be accompanied by improvements in IC (integrated circuit) technology, namely the IC input, processor, output and memory devices which we usually call Chips and their installation can be plug and play, making it easier to use and apply.
