jot notes for the computer project amna and saimon

• graphic card connects to the computes through the motherboard
• the motherboard supplies power to the card and lets it communicate with the c.p.u( the central proccessing unit)
• newer graphic cards often require more power than the mother board can provide, so they also have a direct connection to the computer's power supply
• connections to the motherboard are usually through one of the three interfaces: 1.(pci) peripheral component interconnect). 2.(agp) advanced graphics port. 3. (pcie) pci express
• pci is the newest fastest transfer rates between the transfer card and the motherboard.
• pcie : supports two graphic cards in the same cpomuter
• some cards have two dvi connectors instead. but that doesnt rule out using a crt screen .
• most people only use monitor connections.
• some cards have connections for : tv display: tv out or s- vidoe. 2. analog vidoe cameras: vivo or video in / video out. 3. digital cameras :firewire or usb
• the top of the line good graphic cards are easy to spot, it has a lot of memory and a fast processors.
• the end of the line card provides power than most people really need .
• people who need the power of the high end card include gaming enthuasiats and people who do lots of 3-d graphic work.
• the frame rate describes how many complete images the ca4rd can sisplay per second. the human eye can process about 25 frames every second, but fast action games require a frame rate at least 60 fps (frames per second), to prvide smooth animation
• triangles or vertices pr second: 3d images are made of trianglesaor polygons. this measurement describes how quickly ,the gpu can calculate the whole polygons or vertices that define it.
• pixel fill rate:this measurement describe how many pixels the gpu can process in a second, which translates to how qucikly it can rasterize the image.
• gpu clock speed (MHz0
• size of the memory bus(bits)
• amount of available memory(Mbg)
• memory clock rate (MHz)
• memory bandwidth (GB/s)
• RAMDAC speed(MHz)
