Understanding the Operating System

The operating system is a software system whose job is to perform control and management of hardware and basic system operations, including run software applications such as word processing programs and web browsers.

In general, the Operating System is software on the first layer is placed on computer memory when the computer starts up. While other software is run after running the Operating System and Operating System will perform the core public service for the software. Common core services such as access to the disk, memory management, task scheduling, and user interface. So that each software no longer need to perform the core duties of the public, because it can be served and performed by the operating system. Section of code that perform the core duties and the general is called the "kernel" an Operating System.

The device operating system is an important part in running a computer device. The operating system is software that bridges between the user and the hardware used is a computer.
As for the operating system is:
- Multiuser: can be used by multiple users
- Multitasking: can perform many tasks

SCHEME OF COMPUTER SYSTEMS

A. HARDWARE PRODUCT (HARDWARE)
 Is a physical component which consists of a series of computer electronics and other mechanical equipment. Abtraksi top level consists of four components, namely:

   
1. Processors (processor)
   
2. Main Memory (Main Memory)
   
3. Input and output devices (Device I / O)
   
4. Interconnection between components> (user interface, device controler)
Hardware Resources (Hardware) consists of:

1. PocessingComputer components are assigned to process data and perform various commands.Processing consists of:

    
* The ALU (Arithmetic Logic Unit) for computing, in the form of arithmetic and logic operations.
    
* The CU (Control Unit) for controlling operation of a computer system implemented.
These registers assist in the implementation and operation as the operand-operand of the operation is performed.
Control and Status Register to consist of:

   
1. To address and buffer registers (MAR, MBR, I / O AR, I / O BR)
   
2. Register for the execution of instructions (PC, IR)
   
3. Register for status information (PSW) contains the sign, carry zero, equal, overflow, interrupt enable / disable, supervisor.
 
2.  Memory
Serves a place to store data and programs.According to the order from top to bottom can be measured in terms of hierarchy:

   
1. Access speed
   
2. Relations capacity
   
3. Usage frequency relationship
   
4. Relationships Price
3. Device Input / Output

   
1. Mechanical component is the device itself
   
2. Electronic components of the control device controller chip
Controlling the device there are two kinds:

    
* Mover tool (Device Controller)
    
* Workers' tool (Device Drive)
The structure of I / O

   
1. I / O interrupts> I / O device excl low
   
2. DMA structure> I / O device excl high
DMA is divided into: Third Party and First Party DMA DMA
4. Interconnection between components

 known strains / lines (buses) are located on the mainboard, the bus consists of three kinds:

   
1. Address bus (address bus), one-way. 16, 20, 24 lines
   
2. Data bus (data bus), two-way. 8, 16, 32 lines
   
3. Bus control (control bus), two-way. Lines 40-10
Mechanisms Reading:Memory read command signal to the device memory to release data on the location to read data bus to the CPU. Interconnection between components forming a popular type of connectivity, among others, ISA, VESA, PCI, AGP.
Computer Concepts levelConsists of:

    
* Block diagram (top)
    
* Architecture
    
* Transfer register
    
* Series Switches
    
* Electronics (Lowest)

   
1. Rate Concept Electronics
   
2. Rate Concept Series Switches
   
3. Register Transfer Level Concept
   
4. Concept Level Architecture
   
5. Concept Level Block Diagram
2. Computer WorkComputer work at the conceptual level, among others:

    
* Level Block Diagram Concept
    
* Register Transfer Level
    
* Level Concept Switch
B. SOFTWARE SOFTWARE

    
* Represents a collection of non-physical components of the program and its data structures
    
* The program is a set of instructions that are structured in such a way as to be able to solve certain problems as needed.
Instruction CycleThe process of instruction is done through two stages:

   
1. Taking instruction (Instruction Fetch)
   
2. Execute the instruction (Instruction excution)

    
* Interrupt> signal from an external device causes an interrupt is a program (Division by zero) and timer (Quantum on the Round Robin).
    
* Trap> Generated software interrupt caused by error or because of user demand.
