Comp ports

  1. 1. Computer PortsIntroduction Some DetailsClassification ComparisonVarious Ports Conclusion Archit n Krutarth 1
  2. 2. Introduction• Interface – between the computer and other computers or peripheral devices• Plug/Cable• Entrance/Door – “poort”; Air port; Mundra Port• Port vs Bus Archit n Krutarth 2
  3. 3. Classification• Serial/Parallel ports• Hot-swappable ports – Can be connected while equipment is running• Plug-and-play – Automatically start handshaking• Auto-detect – some sound cards allow plugging in several different types of audio speakers• Technologies – Optical (light) fiber, microwave, and others Archit n Krutarth 3
  4. 4. Computer Ports• Serial Port • Ethernet or Network• Parallel Port Port• PS/2 Port • Game port• USB • DVI Port• VGA Port • SCSI• Power Connector • HDMI• Modem • PCI• Optical Audio • Thunderbolt• SATA • And so on . . . . Archit n Krutarth 4
  5. 5. Color Codes• Orange, purple, or grey: Keyboard PS/2• Green: Mouse PS/2• Blue or magenta: Parallel printer DB-25• Amber: Serial DB-25 or DB-9• Pastel pink: Microphone 1/8" stereo (TRS) mini jack• Pastel green: Speaker 1/8" stereo (TRS) mini jack Archit n Krutarth 5
  6. 6. Computer Ports• Serial Port • Ethernet or Network• Parallel Port Port• PS/2 Port • Game port• USB • DVI Port• VGA Port • SCSI• Power Connector • HDMI• Modem • PCI• Optical Audio • Thunderbolt• SATA • And so on . . . . Archit n Krutarth 6
  7. 7. Ethernet• LAN• Introduced 1980• 802.3 in 1985• Co-axial, Twisted Pair or Fiber Optics• Too much – It’s a network Archit n Krutarth 7
  8. 8. Ethernet• Heartbeats• 0 and 1 in starting – +0.7 and -0.7 – No collision Transfer further• RJ-45 connector – 8 pins – 4 pairs of lines – Registered jack RJ11, RJ14 or RJ25 Archit n Krutarth 8
  9. 9. Ethernet• Little monitor lights on these devices flicker when in use. Archit n Krutarth 9
  10. 10. VGA Port• Monitor to a computers video card• Looks like serial port but is different in many ways (15 holes vs 9/25 holes)• VGA – Video Graphics Array (Hardware)• Resolution 640*480 – Earlier Desktop – Now mobiles• VGA connector Archit n Krutarth 10
  11. 11. VGA Port • Analog in nature – DTV course • Today, the VGA analog interface is used for widescreen resolutions including 1920×1080. Archit n Krutarth 11
  12. 12. HDMI• High-Definition Multimedia Interface• Uncompressed digital audio/video/data• HDMI Founders : seven companies – Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson (RCA) and Toshiba• Designed in December 2002• To improve on DVI-HDTV by using a smaller connector and adding support for audio, and enhanced support for YCbCr and consumer electronics control functions. Archit n Krutarth 12
  13. 13. HDMI• Parallel – 3 colors on 3 pins ; clock on 4th• Hot swappable• Plug n play• Auto detect• 10.2 Gbit/s (340 MHz * 3 = 1020) – USB doesn’t have clock Archit n Krutarth 13
  14. 14. HDMI• Protocol TMDS (DVI and HDMI) – Transition Minimized Differential Signaling – Video Data Period – Data Island Period – Control Period• Compatibility : SCART, VGA, RCA, etc. – Using scalar (digital-to-analog converter) – relatively complex and expensive Archit n Krutarth 14
  15. 15. HDMI• Applications – Blue ray disc; HD-DVD – Digital camera; cam recorders – PCs – Tablets – Mobiles Archit n Krutarth 15
  16. 16. USB• All devices printers, mice and all• USB hub - 127 devices to a USB port. – Speed share• Draw power• USB 2.0 -480 Mbps.• USB 3.0-5 Gbps (bi-directional)• 4 pins• No clock Archit n Krutarth 16
  17. 17. SATA• Serial At- Attachment – Attachment to IBM PC• Use : Host bus adapters to mass storage devices such as hard disk drives and optical drives.• Before SATA – PATA• SATA - 7 conductors• PATA-40 conductors• SATA 3.0 Around 600 Mbps practically Archit n Krutarth 17
  18. 18. SATA• Every hard drive, SSD, and internal optical drive is connected to SATA these days.• Created in 2003• The SATA-IO group collaboratively creates, reviews and ratifies Archit n Krutarth 18
  19. 19. SATA Archit n Krutarth 19
  20. 20. PCI express• Peripheral Component Interconnect Express• replace the older PCI, PCI-X, and AGP bus standards• Serial Communication• External interface with PCI Express External Cabling, such as Thunderbolt• Designer : Intel, Dell, HP, IBM• Maintainer : PCI-SIG (PCI Special Interest Group) Archit n Krutarth 20
  21. 21. PCI express• Purpose: – Devices connected to the bus appear to the processor to be connected directly to the processor bus, and are assigned addresses in the processors address space. – Independent of particular processor – Connect GPU or any expansion card to processor Archit n Krutarth 21
  22. 22. PCI express• Data rate – Per lane (each direction): • v1.x: 250 MB/s • v2.x: 500 MB/s • v3.0: 1 GB/s • v4.0: 2 GB/s [November,2011] – 16 lane slot (each direction): [x1,x4,x8,x16,x32] • v1.x: 4 GB/s • v2.x: 8 GB/s • v3.0: 16 GB/s Archit n Krutarth 22
