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 Processing Unit.

6. System Unit The system unit 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 the central 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 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, identify 5 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.

11. Output Devices Individually, identify 5 different Output Devices besides the monitor. (2 minutes)

12. Specifications Commonly known as specs, this are the values used to describe a piece of hardware. Speed Size Storage Capacity Software Version Battery Life Optical, Magnetic, Electronic Amount of ports/connections

13. Microprocessors Specs Think about the specs that we need to look for in a modern C.P. (1 minute)

14. Microprocessors Specs Clock Speed o Measure of how quickly a computer completes basic computations and operations. Hertz (one cycle per second) kilohertz 1000 cycles per second megahertz (Mhz) 1000 000 cycles per second gigahertz (Ghz) 1 000 000 000 cycles per second Common clock speed for todays computers is: o Between 1.5 Ghz and 3 Ghz

15. Microprocessors Specs Cores o Single core. Only 1 operation at a time. o Dual cores. Two operations at a time. o Quad cores. Four operations at a time. Brands:

16. Microprocessor Specs Instructions size: 32 bit or 64 bit. The amount of bits it can use to perform any given operation. It refers to the amount of digits it can handle, or its precision. It’s not the same to be able to add numbers 32 digits long than add numbers 64 digits long. Faster in very specific situations. Requires special software.

17. Which is faster? 1C In groups, select which of the following microprocessors is faster and explain why. (5 minutes) T1 : Mónica, Elena, Diego, Juan Pablo T2: Sebastián, Mayte, Andrea, Adair T3: Eugenio, Eric, Mariana, Fernanda T4: Alejandro, Adriana, Mauricio, Valentina

18. Which is faster? 1A In groups, select which of the following microprocessors is faster and explain why. (5 minutes) T1 : Sarahí, Ana, Alejandro, Rodrigo T2: Diana, Alex, Montse, Jose Luis T3: Adrian, Julia, Federico, Pao T4: Paola, Brenda, Jorge, Mariano

19. Which is faster? AMD Phenom IIIntel Core i7 1.8 Ghz 4 Cores 32 bits 3.0 Ghz 2 Cores 64 bits.

20. C.P.U. fans

21. Mother Board (MoBo) The central printed circuit board Everything is connected to it. It contains the buses that connect all elements between them. Determines kind, type, brand and speed of procesors

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

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