Processing Device Some of the most common processing devices: 1. Central processing unit (CPU) 2. Graphics processing unit (GPU) 3. Motherboard 4. Network interface card (NIC) 5. Sound card 1  Processing Device: CPU The CPU is a chip inside the computer. main function is to take input (keyboard, mouse, printer, etc.) or computer program, and interpret what it needs. Then outputs information (monitor, printer, etc.). The first processor released by Intel was the 4004 processor. 2 Processing Device: CPU components There are two primary components. 1. ALU (arithmetic logic unit) - performs mathematical, logical, and decision operations. 2. CU (control unit) - directs all the processors operations. Today, in addition to the different names of computer processors, there are different architectures (32-bit and 64-bit), speeds, and capabilities. 3 Processing Device: GPU -Video card It is used to create a picture on a display. It processes images and video, some of the tasks normally handled by the CPU. 4 Processing Device: GPU -Video card ports DVI (Digital Visual Interface), HDMI (High Definition Multimedia Interface), S-Video (Super Video), VGA (Video Graphics Adapter). Some motherboards may also use an onboard video card, which means the video card is not a separate expansion card like those shown in previous slide. 5  Processing Device: Motherboard Is a printed circuit board and foundation of a computer that is the biggest board in a computer chassis. It allocates power and allows communication to and between the CPU, RAM, and all other computer hardware co mponents. 6 Processing Device: NIC Is a computer expansion card for connecting to a network (e.g., home network or Internet) using an Ethernet cable with an RJ- 45 connector. A network card is sometimes improperly referred to as a broadband card or Internet card. 7 Processing Device: NIC Is a computer expansion card for connecting to a network (e.g., home network or Internet) using an Ethernet cable with an RJ- 45 connector. A network card is sometimes improperly referred to as a broadband card or Internet card. 8 Processing Device: Sound card  Is an expansion card or IC (integrated circuit) for producing sound on a computer that can be heard through speakers or headphones.  Digital Out (white or yellow; words: "Digital" or "Digital Out") - Used with surround sound or loudspeakers.  Sound in or line in (blue; Arrow pointing into waves) - Connection for external audio sources, (e.g., tape recorder, record player, or CD player.)  Microphone or Mic (pink) - The connection for a microphone or headphones.  Sound out or line out (green; Arrow pointing out of waves) - The primary sound connection for your speakers or headphones. This sound card also has a second (black) and third (orange) sound out connector.  FireWire (not pictured) - Used with some high-quality sound cards for digital video cameras and other devices.  MIDI or joystick (15 pin yellow connector) - Used with earlier sound cards to connect MIDI keyboard or joystick. 9
