2. Different types of Hardware for your computer Adapter Cards Graphics Cards Sound Cards RAID Cards eSATA Cards I/O Cards Wired And Wireless Network Cards Capture Cards

3. Adapter Cards • An Adapter Card (which is also known as an expansion card) is a circuit board that's put into a expansion slot of a motherboard to give more functionality to the computer.   • The main focus of an Adapter card is to provide  features that are not normally offered on some motherboards • Graphics Cards • Sound Cards • Network Cards

4. Graphics Cards     • A graphics card (aka Video Adapter, Graphics Accelerator Card, Display Adapter, or video card)  is an expansion card that generates output images to a display monitor. • Added features to a graphics card • 3D rendering • video recording • MPEG-2/-4 decoding (compressing of videos) • Light pen • TV Output • Multi-Monitors

5. PCI AGP or PCIe Video/Graphic Cards

6. PCI  Peripheral component interconnect  Uses bus architecture Can be integrated circuit fitted onto the mother board or an expansion card Coexist with other expansion buses "Plug and Play • AGP • Accelerated Graphics Port • Originally created for 3-D computer graphics • Provides dedicated pathways between the slot and the processor • Point-to-Point connection allowing higher clock speeds • PCIe • Express • Replaced AGP and older PCI versions •  Uses Point-to-Point serial connection rather than shared parallel communication •  Not compatible in PCI slots • Multiple data lanes

8. Things to Keep in mind • Bigger Monitors with higher resolution (while running the same program) need better video cards • Make sure your Power Supply has enough power to support your Videocard • Making sure your output is supported • Blue Ray will need a video card which supports: • HDMI • HDCP (High-Bandwidth Digital Content Protection) • Allows you to stream blue ray from your Video card to the TV)

9. Things to keep in mind cont. • Running 2 Video Cards at once • Depends on the chipset of your motherboard • Scalable Link Interface (SLI) Nividia chipset that allows you to run multiple videocards • Crossfire is a Intel chipset that allows multiple video cards to run • Need a USB 2.0 Display Adapter to run  Multi-Monitor  while using SLI/Crossfire

10. Overclocking and Benchmarking • Overclocking- Process of running the video card at a higher bits/second than it was meant for.  It's used for minimizing/maximizing performance. • Benchmarking- Tests a video card performance and then gives results to compare to other benchmarkers. • http://www.videocardbenchmark.net/

11. Multimedia Cards Sound cards, TV tuner cards, Capture cards

12. Sound Cards • Sound Cards (aka Audio Cards) is an Adapter Card that enable's the input and output of audio signals between the itself and the computer. • Multiple inputs: • Pink- Microphone input • Blue- Audio input • Green- Audio output • Front speakers  • Headphones • Brown- Audio output for Right to Left Speaker • Black- Audio output surround sound speakers • Orange- Audio output for subwoofer

13. TV Tuner Cards • Computer component that allows television signals to be received by a computer • 4 components are required to make this happen • A tuner device • An antenna or cable connection • A tuning application • Some sort of program guide

14. Video Capture Cards • Video capture cards are designed to plug directly into expansion slots in personal computers and servers • All comply with one of the popular host bus standards (PCI, AGP, and/or PCIe) • Proper hardware and software are necessary to transport the captured video to the computer • Problems arise with dropped frames, problems synchronizing audio and video, and poor quality play back.

15. RAID Cards • RAID Controller Cards are pieces of hardware dedicated to controlling RAID functions. • RAID chips can be integrated into the Motherboard • RAID Controller Cards will come in the form of PCI, or PCIe • RAID 0 and RAID 1 can be setup either by software, or hardware.  RAID 5 is setup by hardware.

16. I/O Cards • Input/ Output (I/O) cards are cards that provide some sort of external connectivity. • USB, Parallel, SATA, SCSI, and NIC/WNIC cards • Although often times USB, Parallel, and SCSI cards are very much out of date.  Now integrated in with the Motherboard. • Often times I/O Cards are labeled as "Low Profile Cards" which are cards that fit in smaller computer towers.

17. SCIS: Small Computer Interface System • Pronounced "scuzzy" • Involve chains, IDs, and termination • Chains: a series of SCSI devices working together through a host adapter (the host adapter provides the interface between the SCSI chain and the PC) • Categorized as internal and external devices • IDs: range from 0-15, doesn't matter which device gets which number and numbers can be skipped but none can be the same • Termination: Only terminate the ends of the SCSI chain. Some devices come automatically able to terminate others need to be set. Termination is used to prevent the electrical echo.

19. Serial Cards • Replaced by USB •  One of the last manually configured ports • Serial communication: one wire to send data and another wire to receive data one bit at a time sequentially • The job of a serial port is to convert data moving between parallel and serial devices • Serial ports consist of two pieces: • 9-pin DB connector • UART chip • The UART chip actually does the conversion between the serial data and parallel data • Universal asynchronous receiver      /transmitter

20. Parallel Cards • Also known as the printer port • Faster alternative to serial communication • Parallel communication: sending several data signals simultaneously over several parallel channels •  IEEE 1284 is a standard that defines bi-directional parallel communications between computers and other devices •  Max data transfer rate: 150 kilobytes per second • Use up a considerable amount of CPU • Replaced by USB

21. USB: Universal Serial Bus • Replaced serial and parallel ports/cards • Used to establish communication between devices and a host controller • USB host controller: integrated circuit that is usually built into the chipset and controls every USB device that connects to it • USB root hub: the part on the host controller that makes the physical connection to the USB ports • No limit to number of ports a single host adapter may use • Most important thing to remember is that every USB device connected to a single host adapter/root hub shares that USB bus with every other device connected to it • The more USB devices connected result in the bus slowing down and more power being used

22. "Low Profile Cards:"eSATA Cards • External Serial Advanced Technology Attachment (eSATA)  • SATA is a computer bus port that connects Host Bus Adapters to Storage devices. • eSATA cards will take up a PCI or PCIe slot.

23. Network Cards • Network Interface Controller (NIC) is a card that connects the computer to a network.   • Connects via a wire based network • Ethernet- frame-based technology • NIC's are an OSI Layer 1, and layer 2 device • Open Systems Interconnection Model (OSI) makes up seven layers.  Layer 1 is the physical layer, and layer 2 is the data link layer • 48-bit serial number: Media Access Control (MAC) Address • Stored in ROM, every card has a unique address • No 2 cards will have the same address.

24. Wireless NIC's • Wireless Network Interface Controller (WNIC) • NIC that connects to radio-based network. • Works on OSI Layers 1 and 2.   • Uses antenna's to send signals through microwaves. • Connects through PCI Slots, or USB.

25. Display Devices • Three main types: •  Projectors • CRT • LCD

26. Projector • Projects an image or moving images onto a surface usually a projection screen •   Been used throughout the 20th and 21st centuries in places such as movie theatres and classrooms

27. CRT • Stands for Cathode Ray Tube which is a vacuum consisting of one or more electron guns •  Color CRT tubes use three different phosphors which emit red, green and blue light • CRTs have been phased out, mainly because of the advance of LCD technology

28. LCD • Liquid Crystal Display (LCD)- Thin Electronic Visual Display that uses light properties of liquid crystals • Six levels of display • Polarizing filter with a vertical axis which polarizes light • Glass Substrate with Vertical ridges that appear whtn the monitor turns on • Twisted nematic, which contains elements that twist and untwist at different degrees to let light go through • Glass substrate with horizontal ridges to line up with the filter • Polarizing filter with a horizontal axis which blocks and passes light • Reflective screen to send light back to the user. • http://en.wikipedia.org/wiki/File:LCD_layers.svg

29. Resolution • http://en.wikipedia.org/wiki/File:Vector_Video_Standards2.svg

30. Contrast Ratio and Native Resolution • Contrast Ratio • Ratio of luminous intensity of white to black that the Monitor is able to show • Native Resolution • LCD Monitors have a single fixed resolution • While a  CRT Monitor displays at different resolutions, an LCD needs to have a scaling of the image which is lower quality • http://en.wikipedia.org/wiki/File:Native-resolution_800x600_on_1024x768.JPG

31. Connection Devices • VGA • Component/RGB • S-Video • HDMI • DVI 

32. Types of DVI

33. Settings of the Monitor • Refresh Rate- The Frame rate of how many times in a second that the display device fraws the data • Degaussing- Process of getting rid of  magnetic field • Multi-Monitor- use of multiple displays • Monitors • Television • Projectors
