Slide 1

Fundamental I/O Devices for a PC Keyboard Pointing gadget Video show

Slide 2

Keyboards Design Traditional straight plan New ergonomic outline

Slide 3

Correct Position at the Keyboard

Slide 4

Keyboards Two basic advances in the way the keys reach Foil contact Metal contact Logical movement Make code Break code

Slide 5

Keyboard Connectors PS/2 connector (little DIN) Six pins DIN connector Round with five pins USB port Cordless

Slide 6

Pinouts for Keyboard Connectors

Slide 7

Two Common Keyboard Connectors

Slide 8

Keyboard Connector Adapters

Slide 9

Pointing Devices

Slide 10

Two Mouse Technologies Wheel mouse Optical mouse

Slide 11

How a Wheel Mouse Works

Slide 12

Methods of Mouse Connection Use the serial port (serial mouse) Use a committed round mouse port coming straightforwardly from the framework load up (framework load up mouse or PS/2 good mouse) Use a mouse transport card that gives the same round mouse port (transport mouse) Use the USB port Use a Y-association with console Use a cordless innovation

Slide 13

Cleaning the Mouse Remove the spread Clean the rollers with a cotton swab plunged in a little measure of fluid cleanser

Slide 14

Other Pointing Devices Trackballs Touch cushions

Slide 15

Computer Video Primary yield gadget of a PC is the screen Two essential parts for video yield Video controller Monitor

Slide 16

Monitors Rated by screen size, determination, revive rate, interweave highlights Most meet benchmarks for Super VGA Use either more seasoned CRT innovation or new LCD innovation

Slide 17

How a CRT Monitor Works

Slide 18

Choosing the Right Monitor

Slide 19

Monitors and ELF Emissions ELF emanations = to a great degree low recurrence discharges (of attractive fields) Most screens consent to the MPR II standard; not very many follow the more stringent TCO \'95 principles

Slide 20

Flat Panel Monitors Are worked to get either a simple sign or a computerized signal from the video card and have two ports on the screen to oblige either flag

Slide 21

Flat Panel Monitors Compared to CRT screens they: Take up substantially less work area space Are lighter Require less power to work Provide a clearer, more exact picture Cost three times more

Slide 22

Layers of the LCD Panel

Slide 23

LCD Panels on the Market Active-lattice A transistor that intensifies the sign is put at the convergence of every cathode on the network, which encourage upgrades pixel quality Dual-filter inactive grid Two segments of terminals are enacted in the meantime Less costly and does not give as high caliber a picture as dynamic lattice show

Slide 24

Video Cards Provide interface amongst screen and PC Also called realistic connectors, video loads up, illustrations cards, show cards Main elements to search for in a video card The transport it utilizes (impacts velocity and execution) Amount of video RAM it has or can bolster

Slide 25

How a Video Card Works

Slide 26

The Bus Used by the Video Card Since 1995, video cards have been intended to utilize just the PCI transport and all the more as of late to utilize the AGP opening Older video cards were made to keep running on VESA neighborhood transports (VL-transport), an exclusive nearby transport, ISA transports, and EISA transports The speediest transport for video on a framework load up today is AGP with a 32 expansive information transport, running at up to 1 GB/sec Regular AGP space: 132 pins AGP Pro: 188 pins

Slide 27

Video Card Performance on the video card is influenced by: Chip set Memory RAM DAC Bus speed and size Methods of enhancing execution Dual-porting Place a processor on the video card to make it a representation quickening agent

Slide 28

Graphics Accelerator A kind of video card that has its own processor to help execution Necessary with the requests that realistic applications make in the mixed media environment Processor is particularly intended to oversee video and illustrations Their elements lessen the weight on the framework load up CPU and perform the capacity much quicker than the framework load up CPU

Slide 29

Graphics Accelerator Features MPEG deciphering 3-D illustrations Dual porting Color space transformation Interpolated scaling EPA green PC bolster Digital yield to level board show screens Applications support for mainstream high-force design programming

Slide 30

Video Memory Necessary to handle vast volume of information created by expanded determination and shading Stored on video cards as memory chips

Slide 31

How Much Video Memory Is Needed? Controlled by Screen determination (measured in pixels) Number of hues (shading profundity) Enhancements to shading data called alpha mixing

Slide 32

Memory Needed to Hold the Frame Buffer

Slide 33

Bus Width

Slide 34

Bus Width

Slide 35

Types of Video Memory VRAM (video RAM) MDRAM (multibank DRAM) SGRAM (synchronous representation RAM) WRAM (Window RAM) 3D RAM

Slide 36

Chapter Summary Procedures and rules basic to most establishments of I/O gadgets How to utilize serial, parallel, USB, IEEE 1394 ports, and development spaces Essential I/O gadgets for a PC Keyboard Pointing gadget Monitor
