Structure and Computer Function

Computer structure is defined as manners from every component mutual related. while computer function is defined as operation each component as part from structure. as to function from each component in structure above:

• Input device (input tool)computer hardware that functioned as a means of for data insert or command into computer
  
• Output device (product tool)computer hardware that functioned to display product as data processing result. product can be in the form of hard-copy (to paper), soft-copy (to monitor), and or shaped voice.
• I/O ports this part is used to get and or send data out system. device input and output above linked pass port this.
• CPU (central processing unit) cpu be computer system brain, and has two operational function parts, that is: rice pestle (arithmetical logical unit) as data processor centre, and cu (control unit) as computer work controlling.
  
• Memory
  memory divided be two parts that is internal memory and external memory. internal memory shaped louvre (random access memory) that functioneds to keep program whom we process for, and rom (read only memory) that is memory haya can be read and useful as penyedia information at the (time) of computer first time lighted.
  
• Bus Data
  data transfer stripes deliver module in computer system. because at one time certain each only can bring 1 data beet, so channel total determine beet total that can menransfer at one time. wide this bus data determines system performance as a whole. in character bidirectional, mean cpu can read and menirma data passes this bus data. bus data usually consist of 8, 16,32, or 64 parallel stripes.
  
• Address Bus
  used to indicate source location and or aim in data transfer process. in this stripe, cpu will send memory address that be written or read. address bus usually consist of 16,20,24, or 32 parallel stripes.
  
• Control Bus
  control bus is used to controls use with access to bus data and address bus. consist of 4 samapai 10 parallel stripes.
