  1. Hardware

  2. Motherboard • Sections: • PCI slot • PCI-Express slot • CPU • Chipset • DIMM slot • Drive connector • Power Supply • CMOS battery • On-board cards

  3. CPU • Type: • IBM compatible (Intel & AMD) • Apple (formerly: Motorola & IBM, Now: Intel) • Chipset • Heat sink • Speed: MHz, GHz • Number of Bits: • 32-bit processors • x86 processors • 32-bit processing with 64-bit instructions • x86-64 (AMD64) • 64-bit processors • X64 (IA64) • 32-bit OS can only address up to 4 GB of memory

  4. Power Supply • Form factor: ATX, BTX, … • Use a power supply that is rated about 30 percent higher than you expect the system will use

  5. Storage • Primary: RAM, [Cache?] • DIMM (Dual Inline Memory Module) • volatile • Secondary: Hard drive, CD, … • Hard Disk Drive (HDD) • Mechanical (magnetic) disk • Solid state disk (SSD) – Flash memory • Connection: • SATA (Serial ATA), • PATA (Parallel ATA) or IDE • USB, Fire-wire, … • USB flash, Memory card (SD card, …), Floppy Disk Drive (FDD)

  6. Keyboard • Sections: • Alphabetic • Numeric keypad • Function keys • Movement (arrow) Keys • Modifier Keys • Editing Keys • Layout • QWERTY • Dvorak • Keyboard buffeing

  7. Monitor • Types: • CRT(cathode-ray tube) • Refresh rate: 70Hz • LCD(liquid crystal display) • Response time: 16 ms (~ 60 Hz) • Native resolutions • Analog VGA connector – DVI connector • LED • Features of monitor • Screen size, refresh rate (response time), resolution, color quality, …

  8. Device Driver • Small programs stored on the hard drive that tell the computer how to communicate with a specific hardware device • System BIOS uses settings stored in the CMOS RAM chip on the motherboard to know how to start the system

  9. Exercise • Find the hardware information of your PC. • BIOS setup • System Tools-> System Information (msinfo32.exe) • Task Manager • Homework
