Computer

dkfjakdjsf
  • The brand of the computer is Dell
  • The model is Optiplex GX270
  • According to Wikipedia, a computer is “a programmable machine designed to automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem. An important class of computer operations on some computing platforms is the accepting of input from human operators and the output of results formatted for human consumption.” (in Wikipedia. Retrieved Feb. 20 2012, from http://en.wikipedia.org/wiki/Computer).









Processor

The processor is located underneath the fan and it is attached on top of the motherboard.
  • The brand and model is Intel Pentium® 4
  • It is capable of 2.80 GHz
  • According to Kioskea, a processor, also known as CPU for central processing unit, "is the computer's brain. It allows the processing of numeric data, meaning information entered in binary form, and the execution of instructions stored in memory. " (in Kioskea. Retrieved Feb. 20 2012, from http://en.kioskea.net/contents/pc/processeur.php3).













RAM

The RAM is found on the upper left-hand side of the motherboard.
  • Samsung
  • Two 256 megabytes RAMs were found, for a total capacity of 512 megabytes
  • According to Wikipedia, random access memory, known as RAM, is “a computer memory that can be read from and written to in arbitrary sequence in a very high speed for computer and laptop.” (in Wikipedia. Retrieved Feb. 20 2012, from http://en.wikipedia.org/wiki/Random-access_memory).









Optical Disk Drive

The DVD drive can be found to the left of the hard drive, opposite the motherboard.
  • This computer contains a DVD Drive
  • According to Wikipedia, a DVD drive is a "disk drive that uses laser light or electromagnetic waves near the light spectrum as part of the process of reading or writing data to or from DVDs. Optical discs are typically used to back up relatively small volumes of data. Additionally, they are also very commonly used in computers to read software and consumer media distributed on disc, and to record discs for archival and data exchange purposes." (in Wikipedia. Retrieved Feb. 20 2012, from http://en.wikipedia.org/wiki/DVD_drive).










Power Supply Unit

The power supply is located to the right of the motherboard
  • Output a maximum of 210 watts of power
  • According to Wikipedia, a power supply unit in a computer “converts mains AC to low-voltage regulated DC power for the internal components of the computer. Modern personal computers universally use a switched-mode power supply. Some power supplies have a manual selector for input voltage, while others automatically adapt to the supply voltage.” (in Wikipedia. Retrieved Feb. 20 2012, from http://en.wikipedia.org/wiki/Power_supply_unit_%28computer%29).









Cables

Numerous cables found inside of the computer
  • The thin cables that connect to the power supply are to transfer battery power, while the flat cables transfer data.













Hard Disk

The hard disk is located to the right side of the DVD Drive, and on the opposite side of the power supply.
  • It can hold a total of 40.0 gigabytes
  • The brand is Western Digital
  • According to Kioskea, the hard drive is "the component which is used to permanently store data, as opposed to RAM, which is erased whenever the computer is restarted, which is why the term mass storage device is sometimes used to refer to hard drives. The hard drive is connected to the motherboard using a hard drive controller which acts as an interface between the processor and the hard drive. The hard drive controller manages the drives linked to it, interprets commands sent by the processor and routes them to the drive in question." (in Kioskea. Retrieved Feb. 20 2012, from http://en.kioskea.net/contents/pc/disque.php3).















Motherboard

The motherboard is located on the left side of the power supply.
  • The lines on the board are lines of communication that helps send data and instructions among itself. According to Wikipedia, a motherboard is the "central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, providing connectors for other peripherals...A motherboard, like a backplane, provides the electrical connections by which the other components of the system communicate, but unlike a backplane, it also connects the central processing unit and hosts other subsystems and devices." (in Wikipedia. Retrieved Feb. 20 2012, from http://en.wikipedia.org/wiki/Motherboard).


















Crystal

The two crystals are located to the right of and above the processor.
  • According to Wikipedia, a crystal, also known as crystal oscillator, is an "electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency. This frequency is commonly used to keep track of time (as in quartz wristwatches), to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers." (in Wikipedia. Retrieved Feb. 20 2012, from http://en.wikipedia.org/wiki/Crystal_oscillator).
