CHAPTER 1 : ASSEMBLY PC, FORMATTING AND DISK PARTITION


DEFINITION OF A COMPUTER

- COMPUTER is An electronic device that can accept data (input), process the input to useful information (process), according to a set of instructions, store the instructions and the results of processing (storage), and produce the information (output).


COMPUTER STRUCTURE :-


                      

STRUCTURE - THE CPU 

* Meanwhile, the CPU itself consists of several components such as:
o registers
– provides storage internal to the CPU
o arithmetic and logic unit (ALU) 
– perform data processing function
o control unit
 – control the operation of CPU
o internal CPU interconnection
 – provides communication among ALU, registers and control unit :-

                                        

                                     
                     

TYPE OF COMPUTER :-

o - Micro Computer

                                         

o - Main Frame

                                          

o - Super Computer





LEVEL OF PROGRAM CODE

*High Level Language

-Level of abstraction closer to problem domain
-Provides for productivity and portability

*Assembly Language
-Textual representation of instruction

*Hardware Representation
-Binary digits (bits)
-Encode instructions and data
