Transcript

  • 1. Latest Advancements in the PC World Parag Beeraka American YouthWorks Digital Connectors Summer Program
  • 2. Agenda
    • What has changed in the recent years
    • What might change going forward
    • What’s the best way to be up to date
  • 3. What has changed recently ?
    • Have you heard about the following
      • CPU’s - Intel’s Sandy Bridge (Core i7, i5, i3), AMD Fusion
      • Hard Drives – SSD (Solid State Drives)
      • Memory – DDR3
      • I/O - USB3, Thunderbolt, HDMI
      • BIOS – UEFI
  • 4. CPU’s – Changes
  • 5. CPU’s – Intel SandyBridge
  • 6. CPU’s – AMD Fusion
  • 7. The new Motherboard
    • Intel BD82HM65 Platform Controller Hub
    • AMD Radeon HD 6490M GPU
    • Quad-Core Intel i7-2630QM Mobile Processor
  • 8. Motherboards – Intel
  • 9. Motherboards – AMD
  • 10. Hard Drives
    • Magnetic Drives
        • Speed and Capacity
          • Speed - 7200, 10000, 15000 RPM
            • Higher the Speed - The more expensive and faster
          • Capacity – 250 GB, 500 GB, 1 TB (TeraByte = 1024 GB)
            • Higher the Capacity – The more expensive
        • Use SCSI, PATA, SATA I, II, III to connect to the MotherBoard
        • Have Caches to speed up access to Disk
    • SSD
      • FLASH based media - No Rotating Media
        • Getting Popular – Expensive when compared with IDE but way FASTER
        • Use SATA II, III to connect to the Motherboard
  • 11. Hard Drives
  • 12. Hard Drives
    • RAID (0/1/2/3/4/5/6)
      • Technology for replicating and recovering Data
      • Combine Multiple Disk Components into one Logical Unit
      • For superior replication and recovery - Need support in the Chipset
  • 13. Memory
    • RAM – Random Access Memory
      • Static RAM (SRAM), Dynamic RAM (DRAM)
        • SRAM is faster and expensive – Difficult to manufacture larger SRAM’s
        • DRAM is the memory used in all the computers (DDR, DDR2, DDR3)
          • DDR3 > DDR2 > DDR1 ( Faster and Lower Power)
    • DRAM (SDRAM)
      • Available as DIMM, SO-DIMM, microDIMM Memory Modules
        • DIMM – Arranged in Rows and Columns (Used in Desktops)
        • SO-DIMM – Small Outline DIMM (Used in Laptops)
      • Single Sided & Double Sided DIMM’s
        • Used mainly for more capacity (8GB can contain two 4GB DIMM’s in double sided)
      • Single, Dual and Quad Ranked DIMM’s
        • DIMM’s provide multiple Banks for more capacity
  • 14. Memory
    • DRAM (Continued…)
      • Available as Buffered (Registered), Unbuffered DIMM’s and Fully Buffered DIMM’s
        • Buffered DIMM’s are used in Servers (Better Reliability but Expensive)
      • ECC, Parity Check, Parity Error built into DRAM
        • Methods to make sure Memory is not corrupted
      • SPD – Serial Presence Detect
        • Describes Memory Size, Voltage of the DIMM to the BIOS
      • RIMM, SIMM are other DRAM technologies that didn’t become too popular
  • 15. Memory
  • 16. Memory
    • Dual Channel / Triple Channel
      • CPU’s talk to Multiple DIMM Slots at the same time
      • Use the Same Speed DIMM’s
      • Present day CPU’s support Triple Channel
  • 17. Memory
  • 18. I/O
    • Expansion
      • USB
        • Theoretical MaxSpeed of 5Gbps
        • Main advantage of USB is wide user base and its ability to carry POWER
        • Backwards compatible with USB1.0 and USB2.0
        • Move towards Universal Connectivity
      • Thunderbolt
        • Proprietary technology by Intel – Supported by Apple
        • Theoretical MaxSpeed of 10Gbps
        • Available only in latest Apple MacBook Pro laptops
      • PCIe
        • Gen3 - Theoretical MaxSpeed of 8Gbps
        • Usually used to connect Additional Graphics Cards / Audio etc
  • 19. I/O – Speed Comparisons
  • 20. I/O – USB 3.0 New Connector for PC’s
  • 21. I/O - Display
    • Display
      • Two new standards to replace VGA, DVI ports
        • HDMI
          • Royalty based standard
        • DisplayPort
          • Royalty free standard
      • Audio and Video can use only one cable
      • Support for > 1080p Resolution
      • Support Content Protection (You cannot play illegal Blurays  )
      • Most of the newer laptops have either one but not both
  • 22. I/O – Display HDMI Display Port
  • 23. I/O - Network
    • Network
      • Different ways to connect to the Internet nowadays
        • Ethernet - 1Gbps is the standard now
          • 10Gbps, 100Gbps, Fibre Channel – Slowly getting Adopted
        • Wireless - 802.11n is the standard now
          • Theoretical Max of 600Mbps
        • 3G / 4G Technologies and Wi-max

        • Bluetooth
          • Exchange data over short distances
  • 24. UEFI
    • UEFI – Universal Extensible Firmware Interface
    • Common layer above some minimal BIOS (POST, Init etc)
    • Many Motherboard Vendors are moving towards UEFI
    • Advantages :
      • CPU Independent Architecture
      • Faster Bootup Time
      • Motherboard vendors can customize easily
  • 25. What might change going Forward
    • Push to Tablet based Computing
      • CPU’s from Intel and AMD are x86 based
        • Laptops and Desktops are x86 based
      • New push from Mobile Chip Vendors to manufacture Tablets based on ARM Architecture (Interesting Battle going on)
        • iPhone, iPAD and most of the mobile phones are ARM Based
      • Use Laptops as a Primary Device – Use Tablets for Entertainment
    • World is going more and more mobile (Even Business’s)
      • Cellphones are being used for more than just Texting and Talking
  • 26. What might change going forward
    • Push towards Cloud Computing
      • Most of the data is saved on the Internet (Email, Documents, Presentations, Tax Data etc)
      • Main advantage is that you can access the data anywhere as long as you have an Internet Connection from any PC / Tablet.
    • More emphasis on Graphics
      • Youtube videos will be more crisp and clear on Laptops / Tablets
      • Play High Definition games on Laptops / Tablets / Phones
    • More emphasis on Security
      • Since all the data is in the cloud, more Hackers will be eager to hack data
  • 27. What might change going forward
    • More emphasis on Networks
      • Just imagine how much data will be transferred from all these network controlled devices
    • Your Televisions will also be connected to the Internet
      • You can check Facebook messages / E-mail and Video Chat
    • Your Phones might control your Home / Car
      • You can control the temperature of your A/C at Home from a phone
      • You can turn your car on and off from your phone
