• MPU cycle

• The time frame in which system operations are performed.

• firmware

• Programs that are held in a read-only memory.

• personal computer (PC)

• A microchip that combines the arithmetic logic unit and control circuitry of the computer.

• The technology that controls robotic and other automated systems.

• binary logic circuit

• The data storage capacity of a computer that allows information to be saved and retrieved.

• digital electronics

• A random access memory circuit that uses semiconductor devices, called flip-flops, to store data.

• bus network

• An arrangement of bistable devices that makes logical decisions based on input signals.

• static RAM (SRAM)

• A series of registers connected together.

• memory

Match the following

• A cable that interfaces system controllers with programmable instruments and can support (15) device

• parallel transmission

• An interface method in which data is sent one bit at a time over long distances.

• general-purpose interface bus (GPIB)

• An interface method in which multiple bits of data are sent at the same time, following side-by-side

• image acquisition

• Abbreviation for picture elements, which are dots of light that form an image.

• pixel

• A function of machine vision in which a workpiece is illuminated and a picture is digitally created

• serial transmission

A type of computer system data storage that can be altered. Information may be retrieved from and written to random access memory.

• read-only memory (ROM)

• register unit

• logic circuit

• random access memory (RAM)

A memory device that indicates the location in memory of either the instruction currently being performed or the next instruction to be executed.

• octal number system

• program counter

• logic circuit

• firmware

A binary system in which the digits 1 and 0 represent two operational conditions. The value of 0 indicates low voltage or no voltage. The number 1 indicates a voltage larger than 0.

• positive logic

• dynamic RAM(DRAM)

• inverter

• random access memory (RAM)

• counter

A basic computer system function in which an I/O port actuates to either receive data from an input or send data to an output device.

• programmable read-only memory (PROM)

• flip-flop

• NAND gate

• input-output (I/O) transfer

An interface method in which data is sent one bit at a time over long distances.

• serial transmission

• parallel port

• machine vision system

• parallel transmission
