As a student majoring in computer and all computer users, we should know what it is computer, how the structure of computer, etc.

Computer derived from the Latin computare  meaning count. Computer have a very broad meaning and is different for different people.


According to the "Computer Today" ( Donald H. Sanders ) a computer is an electronic system to manipulate data quickly and accurately as well as designed and organized to automatically receive and store input data, processes it and produces an output under the supervision of a step-by-step program instructions that stored in memory ( Stored Program )

According to the book "Computer Organization"  ( VC Hamacher, ZG Vranesic, SG Zaky ) the computer is a fast electronic calculating machine can receive digital input information, process it in accordance with a program stored in memory ( Stored Programs ) and generate output information.

Computer in general definitions :
  • Electronic equipment
  • Can receive data input
  • Can process data
  • Can provide information
  • Using a program stored in computer memory ( stored program )
  • Can save the program and the result of processing
  • Work automatically
Computer Organization :
Parts are closely associated with the operational units and the interconnection between components of a computer system to realize its architectural aspects. Examples are the organization aspects of technology hardware, software interfaces, memory technologies, system memory, and control signals.

Computer Architecture :
More inclined to the study of computer system attributes associated with a programmer. For example, instruction set, the arithmetic is used,  the addressing technique, the mechanism of Input / Output
