  1. Introduction to Hardware

  2. What is binary? • We use the decimal (base 10) number system • Binary is the base 2 number system • Ten different numbers are used in base 10. How many are used in base 2?

  3. Bits & Bytes • kilo, mega, and giga are different in binary! bit (b) – a binary digit KiloBit (Kb) – 210 bits MegaBit (Mb) – 220 bits GigaBit (Gb) – 230 bits Byte (B) – 8 binary digits KiloByte (KB) – 210 bytes MegaByte (MB) – 220 bytes GigaByte (GB) – 230 bytes • http://en.wikipedia.org/wiki/Binary_prefixes

  4. Storage Scam! • Example: iPod Nano 16GB

  5. Input Devices • Keyboard • Mouse • Webcam • …any others?

  6. Output Devices • Monitor • Printer • Speakers • any others?

  7. Power Supply • Often comes included with the case • Connects computer to electricity

  8. Central Processing Unit (CPU) • Computer’s thinking/calculating brain part • Pay attention to: • Model (e.g. Intel Core i5) • Clock speed (e.g. 2 GHz) • Socket type (e.g. LGA 1156)

  9. Random Access Memory (RAM) • Computer’s memory part of the brain • Pay attention to: • Brand (e.g. Crucial, Kingston) • Size (e.g. 2GB) • Speed (e.g. DDR3 1333 MHz)

  10. Graphics (Video) Card • Specializes in displaying graphics • Pay attention to: • Brand (NVIDIA, ATI) • Size (512 GB) • Speed

  11. Hard Drive • Stores everything • Pay attention to: • Brands (Western Digital, Seagate) • Speed (e.g. 7200 RPMs) • Size (e.g. 512 GB)

  12. CD/DVD • Pay attention to what it can burn…

  13. Motherboard • Connects EVERYTHING!

  14. Build Your Own PC • Websites that let you buy parts: • www.newegg.com • www.tigerdirect.com • www.mwave.com • FAQs • http://www.reddit.com/r/buildapc/faq
