Section 5 Supporting I/O DevicesSlide 2
You Will Learn… How to introduce fringe I/O gadgets How to utilize ports and extension openings for extra gadgets About consoles and how to investigate them About various sorts of directing gadgets How screens and video cards relate toward the framework, and how to investigate themSlide 3
Basic Principles of Peripheral Installations Peripheral is an equipment gadget controlled by programming; must introduce both equipment and programming Software may be of various sorts; you should introduce all levels More than one fringe gadget may endeavor to utilize same PC assets (IRQ, DMA channel, I/O addresses, or [for 16-bit drivers] upper memory addresses)Slide 4
A Review of System Resources An IRQ is a line on a transport that serves as an intrude on solicitation line and is appointed to a gadget Each gadget needs a gathering of I/O addresses the CPU will use to get the consideration of the gadget and speak with it Older gadget drivers and BIOS written in genuine mode require some upper memory addresses 640K-1024K Some gadgets require a DMA channel to accelerate information exchange over the transport proceeded…Slide 5
A Review of System Resources System assets are doled out at startup PnP gadgets don\'t ask for particular I/O addresses, DMA channels, or IRQs, however utilize those allocated by BIOS and OS Legacy gadgets are not PnP and require exceptional memory assets Sometimes a transport controller is doled out a solitary arrangement of assets for all gadgets utilizing the transportSlide 6
Installation Overview for an Add-on Device Install gadget (interior or outside) Install gadget driver Install application programmingSlide 7
Internal Devices Drives (eg, hard, floppy, CD-ROM, DVD, Zip) Devices that are embedded in development spaces on the motherboard Advantages Less costly than outer gadgets Don\'t consume up work area roomSlide 8
External Devices Use existing port (eg, serial, parallel, USB, IEEE 1394) Use port gave by interface card introduced in extension opening Advantage Can be moved effortlessly starting with one PC then onto the nextSlide 10
Purchasing a Hardware Device Have essential learning of your framework CPU, framework transport, and nearby transport drive Memory Hard drive size OS and rendition Space accessible on hard drive For inside gadgets: what number of drives, sounds, or development openings are accessibleSlide 11
Purchasing a Hardware Device Plug and Play? Offers highlights you need? Documentation simple to peruse and complete? Maker\'s Web webpage offer assistance and specialized backing? Guarantee? Perfect with current equipment and programming?Slide 12
Installing a Hardware Device Use antistatic arm jewelery and ground mat Unplug the PC and expel case spread Locate the opening and evacuate faceplate Insert development card in extension space Insert screw that associates card to case Replace case spread, power line, and peripherals Plug in the gadget Reboot the PC; introduce gadget drivers Test gadgetSlide 13

Null Modem Connection Special link (invalid modem link or modem eliminator) empowers information transmission between two DTE gadgets without the requirement for modemsSlide 23
Pin Connections for a 25-Pin Null Modem CableSlide 24
Infrared Transceivers Use assets of a serial port for correspondence Create a virtual infrared serial port and virtual infrared port for infrared gadgets Sometimes motherboard gives 5-pin association with its own exclusive IrDA-consistent infrared handset Industry is moving far from infrared and toward different remote advancements as a result of viewable pathway issueSlide 25
The Universal Asynchronous Receiver-Transmitter (UART) Chip Controls every one of the nine pins of a serial port Establishes interchanges convention Converts parallel information bits originating from the framework transport into serial bits for transmission Converts approaching serial information bits it gets into parallel structure required by the framework transport UART 16550 driver is incorporated with all Windows working frameworksSlide 26
Using Parallel Ports Transmit information in parallel, eight bits at once Almost constantly female Originally expected for printers; now additionally utilized for data gadgets Cable ought to be no more than 10 feet to maintain a strategic distance from loss of trustworthiness of information Can be arranged as LPT1, LPT2, or LPT3 Port assignments are made in CMOS setupSlide 27

Using USB Ports Designed to make establishment of moderate fringe gadgets as easy as could be expected under the circumstances Much speedier than general serial ports Use higher-quality cabling with four wires—two for force and two for correspondence Easier to oversee; dispose of need to physically resolve asset clashes proceeded…Slide 32
Using USB Ports Allow for hot-swapping and are hot-pluggable Most ebb and flow motherboards have one to four USB ports Managed by a USB host controller As numerous as 127 USB gadgets can be daisy changed together utilizing USB gadgetsSlide 33

Using PCI Expansion Slots PCI transport keeps running in a state of harmony with CPU PCI controller oversees framework assets for all PCI cards Use Device Manager to figure out which IRQ has been doled out to a PCI gadget PCI transport IRQ guiding can take care of issue of not having enough IRQs to bolster all gadgetsSlide 41
PCI Expansion SlotsSlide 43
MCA and EISA Busses Microchannel Architecture (MCA) transport First 32-bit transport for PCs EISA (Extended ISA) transport Designed to contend with MCA transportSlide 44
Using ISA Expansion Slots Configuration is not computerized ISA transport does not oversee framework assets, as do USB and PCI transport aces ISA gadget must demand framework assets at startupSlide 45
