  1. T111 Computer Fundamentals

  2. Review • Draw an Intel P4 motherboard layout (logical). Include: • CPU • MCH • ICH • Memory • HDD • Gfx Card

  3. Review

  4. Review • Draw an Intel Core i7 motherboard layout (logical). Include: • CPU • MCH • ICH • Memory • HDD • Gfx Card

  5. Review

  6. PC Performance • Who needs high performance?

  7. Define Performance… • What types of performance are there? • Processing performance • Graphical performance • Storage performance • Reliability • Redundancy • Power efficiency • Noise level • All of the above?

  8. CPU • Performance Factors • Clock Speed • Architecture • Pipelines • Instruction Sets • Number of Cores • Cache • Memory Bus

  9. The Megahertz Myth • Which is faster? Pentium 4 3.8Ghz Vs Core 2 Duo 2.4Ghz http://www.tomshardware.com/charts/cpu-charts-2008-q1-2008/compare,382.html?prod[1262]=on&prod[1281]=on

  10. RAM • Performance Factors • Size (measured in MB / GB) • Rated Speed (Mhz) • Latency

  11. RAM Specs - explained

  12. HDD • Performance Factors • Drive RPM • Seek time • Buffer Memory (MB) • RAID

  13. Video Card • Performance Factors • GPU clock speed • Memory clock speed • RAM (MB) • Architecture • SLI / Crossfire

  14. Network / Internet • Network Performance factors • NIC speed (Mb / Gb) • Cable specification • Wireless interference • Internet Performance Factors • ISP connection rate • Latency • Line quality / distance from exchange • Load / time of day etc • Port shaping

  15. Other Components • Chipset • Optical Drives • Flash Drives • Display

  16. Moore’s Law • “Since the invention of the integrated circuit in 1958, the number of transistors that can be placed inexpensively on an integrated circuit has increased exponentially, doubling approximately every two years.”-Gordon Moore

  18. Moore’s Law • http://www.youtube.com/watch?v=VxAB7iBz8JU

  19. Software affecting performance • OS • Running Applications • File system

  20. Operating System Performance • http://blogs.zdnet.com/BTL/?p=22006&page=4&tag=col1;post-22006

  21. Running Applications • Number of applications running • CPU load for the application • Resources being used by the application

  22. File System • File System • FAT16 • FAT32 • NTFS • HFS (Mac) • UFS (Unix) • Compression • Encryption

  23. Testing • How can we test performance? • Benchmark tests • Online speed tests • Does it feel fast?

  24. Performance Problems • The PC takes a long time to boot up • It takes a long time to access web pages • The PC is slow to respond when loading applications or running two applications at once • The PC is generally slow and it takes a long time to un zip files or encode MP3s
