COMPUTER SYSTEM


1) Computer: Is a machine.

2) System: is Software.

3) Applications: are programs.

4) Debuggers: is a program that cleans other software errors.

5) Machine Language: is the system code or language that a computer understands directly.

6) Microprogramming: Technical programming a computer

7) Physical Devices: the hardware of the computer.

8) Programs: is a set of sequential instructions or codes that describe, define or characterize the performance (realizacion de una accion) of an action by the computer.

9) Command interpreters: is a computer program that is able to translate the commands entered by users.

10) Platforms: is a system that serves as the basis for certain modules to operate hardware or software of a computer.



**COMPUTER SYSTEM**

Set of electronic elements that interact with hardware according some instructions.

- Software  --------> set of instructions
- Hardware without (sin) software is just useless (inútil)


DIVIDE IN:

ØSOFTWARE
- System software --------> administrate operation of the computer.

    1.  Applications (games, banking systems, accounting systems).
    2.  Compilers, editors, debuggers, command interpreters. 
    3.  Control.


 ØHARDWARE

Open system control all the computer, provide platforms where can be write programs.

     1.   Machine Language.
     2.   Microprogramming.
     3.   Physical devices.



OBJETIVES:

Ø Automatic systems operation.
Ø  Provide information for making decision process.
Ø  Achieve advantages through of implementation and use.


SOFTWARE CAN’T BE TOUCH

HARDWARE CAN BE TOUCH


**ELECTRONIC DATA PROCESSING**

Manage Data With A Machine


Process data in an electronic way. It permits manage a lot of information. Set of data that transmits messages in an electronic way. 


Data --------> Process --------> Information 
 with the processor (instructions, procedures)


ELEMENTS:


Ø  Electronic data( Processor) 
Ø  Peripheral equipment(devices) for input and output (data)
Ø  Procedures to know when, where get data, how to use it 
Ø  Intructions to the processor
Ø  Personal to operatives and supports


STAGES (6)

      1.   Origen --------> Collect Data / Source Documents
      2.   Input         -         Where You Read Data
      3.   Processing            -      Prepare Data / Process
      4.   Output     -          Result after the Process (Information)
      5.   Distribution        -       Reports
      6.   Storage        -    In a Database

PROCESS MODE

1.     Batch --------> One by one
2.     On Line --------> Connect Computers and Read Information
3.     In Real Time --------> Transmit Direct to the CPU
4.     Teleprocessing --------> Modem --------> Transform Signals (Audio)
