Computer Introduction by Sofi Rahmatulloh

Computer is a word that taken from the word "to compute" means a tool that using to counting.
Now computer is used to many thing.

History of Computer :
First computer was made at ENIAC (Electronic Numerical Integrator And Computer)
Made by John and John Eckert.
Used to count the range and trajectory in world war 2 (1946).

Input such as :

• Monitor
• Printer / Plotter
• Audio (Speaker)

 Output such as :

• Camera
• Mouse
• Keyboard
• Microphone
• Scanner
• Digitizer
• Joystick
• Etc.

Part of Computer :

• Data procesing
• Central Processing Unit (CPU)
• AMD, Intel
• Data Storage
• Hardisk Drive
• Memory
• Optical Disk
• Input Output Module
• USB Port
• PS/2 Port
• Serial Port
• Data bus
• Data bus

Processor.
Work as central processing of data and instruction.
Processor performance is determined by :

• CPU Speed.
• GHz
• FSB
• Cache memory.
• A temporary memory that work as a bridge between processor and main memory (RAM)

Storage.
Work as a place to save data temporarily and permanently.
Storage is divided into two kind :

• Internal such as :
  • Main Memory (RAM)
  • Hardisk Drive
• External such as :
  • Optical Disk (CD / DVD / Bluray)
  • FlashDisk Drive.

Input Output Module
Is a module that has function as a bridge between computer with input and output device.

• USB
  • Connect with many device such as : printer, flash disk, modem
• PS/2
  • Connect with mouse and keyboard
• LPT (Serial Port)
  • Used for dot matrik printer and other electronic
• VGA Port
  • For video Output
• Audio Port
  • Input and output an audio
• Bluetooth

Data Bus.
Has a funtion as a bridge between processor, storage, and I/O module.
Its all my post today about Computer Introduction, I hope it can help you.
