  1. How are they called?

  2. Lesson Objectives • All of you should be able to describe the parts of a personal computer • Most of you should be able to identify the performance specifications of the C.P.U. • Some of you should be able to compare two different Microprocessors.

  3. Parts of personal computers Omar Álvarez Badillo

  4. Names http://windows.microsoft.com/en-US/windows-vista/Parts-of-a-computer

  5. The C.P.U. ? • Central ProcessingUnit. Which one is it?

  6. System Unit • The systemunit is the core of a computer system. Usually it's a rectangular box which contains many electronic components that process data. The most important of these components is thecentral processing unit (CPU), or microprocessor, which acts as the "brain" of your computer. 

  7. Microprocessor – The C.P.U. • A microprocessor incorporates the functions of a computer's central processing unit (CPU) on a single integrated circuit (IC, or microchip). Wikipedia http://en.wikipedia.org/wiki/Microprocessor

  8. Input Devices • Any peripheral(piece of computer hardware equipment) used to provide data to a computer. (Wikipedia)

  9. Input Devices • Individually, identify5 different Input Devices besides the mouse and the keyboard. (2 minutes)

  10. Output Devices • Is any peripheral (piece of computer hardware equipment) used to communicate the results of data processing carried out by a computer, which converts the electronically generated information into human-readable form. (Wikipedia) http://www.best-apple-mac-computers.com/image-files/mac-monitors.png

  11. Output Devices • Individually, identify5 different Output Devices besides the monitor. (2 minutes)

  12. MicroprocessorsSpecs • ClockSpeed • Measure of how quickly a computer completes basic computations and operations. • Hertz (onecycle per second) • kilohertz 1000 cycles per second • megahertz (Mhz) 1000 000 cycles per second • gigahertz (Ghz) 1 000 000 000 cycles per second • Commonclockspeedfortodayscomputers? • Between 1.5 Ghz and 4 Ghz

  13. MicroprocessorsSpecs • Cores • Single core. Only 1 operation at a time. • Dual cores. Twooperations at a time. • Quadcores. Fouroperations at a time. • I needto grade fourexams, whichisfaster? • Onepersonthatchecksoneexamevery minute • 4 personsthatcheckoneexamevery 2 minutes. • Howmanyprograms do younormallyhave open at anygiven time?

  14. Brands

  15. AMD familynames: • Phenom X2, X3 and X4 • X stands fortheamount of cores • High performance processors • Turion , Turion X2 • Processorsspecificallydesignedformobiledevices • Opteron • Medium and Low performance processors. • Old processors: • Athlon, Opteron

  16. Intel familynames • Intel i7 • 4 cores, high performance • Intel i5 • 4 ó 2 cores, medium and high performance • Intel i3 • 2 cores, medium and lowperfromance. • Old processors • Celeron, Dual Core, QuadCore, Core 2

  17. 32 or 64 Bits? • Theamount of bits they can use toperformanygivenoperation. • Itreferstotheamount of digitsit can handle, oritsprecision. • It’snotthesameto be abletoaddnumbers 32 digitslongthanaddnumbers 64 digitslong. • Faster in veryspecificsituations. Requiresspecial software.

  18. C.P.U. fans

  19. MotherBoard (MoBo) • The central printedcircuitboard • Everythingisconnectedtoit. • Itcontainsthe buses thatconnectallelementsbetweenthem. • Determines kind, type, brand and speed of procesors

  20. RAM • Random Access Memory. • Temporary things • Different from the Hard Disk Drive. • All programs you are running. • The more windows, programs and files you open the more RAM you need. • Used only by the computer, users can’t access them.

  21. RAM Specs • Can be upgraded. • Size • Megabytes (MB) • Gigabytes (GB) • One two or four modules depending on MoBo • Normally between 2 to 4 GB • They also have speed. • 400Mhz up to 1600 Mhz
