OPERATION SYSTEM FUNCTION

Access to any hardware that connected to the computer is provided by the operating system through an application known as the driver.

Each Driver designed to controll the hardware/

1. Controlling Hardware

This is made possible by the operating system because at the time of installation of the operating system there is a process to format the hard drive. Through the process of disk space will be arranged such that they have certain blocks to save the file. This process is similar to the placement of shelves at the empty space to be filled in later books. A file is a collection of blocks that are interrelated and have a name. Folder is a container that can contain files or sub-folders other. Each of the files related to the computer program are placed in a separate folder for easy file search.

2. Manage File and Folder

Command Line Interface (CLI)User interaction with the system is done by using a series of sentences to be done by computer command.

Management functions in user applications could include:◦ Install, the process of placing the program files on

the computer system including the configuration of the program.

◦ Uninstall, the process for deleting files along with the configuration of the computer program.

◦ Update / Upgrade, the process for improving the files of the programs you have installed.

4. Manage Application

Other Capabilities Operating System:1. Multi-user - two or more users can work

together to mutually share the use of applications and resources such as a printer at the same time.

2. Multitasking - the operating system can run more than one application user.

3. Multiprocessing - operating systems can use more than one CPU (Central Processing Unit).

4. Multithreading - each program can be broken down into threads to then be run separately (parallel) by the operating system. This capability is also included as part of the application multitasking.

There are two differences between the operating system 32-bit and 64-bit. 32-bit operating system can only accept a

maximum of 4 GB of RAM, whereas a 64-bit operating system is able to use more than 128 GB of RAM.

Memory management of 64-bit systems is also better, so it can run on a faster application process.

Windows, Ubuntu and openSUSE are some examples of operating systems that support 32-bit architecture.

Operating system 32-bit and 64-bit

Desktop operating system, which is widely used office-Office, Small Office / Home Office (SOHO), with the number of users that little.

Network operating system, Network Operating System (NOS), designed to serve the user in large quantities for a variety of purposes and is widely used in large-scale enterprises.

Based on Usage

Characteristics: Supports use by one user Sharing files and folders in a small network

with minimum security Currently on the market, the desktop

operating system most widely used is divided into three major groups, namely Microsoft Windows, Apple Mac OS, and UNIX / Linux.

OPERATING SYSTEM DESKTOP

Characteristic: Supports use by more than one user Run applications that can be used by more than

one user Stable (robust), where there is little possibility

for error in the program. Robustness is a term to indicate the ability of a computer system to handle problems that occur during use by the user.

Having a data security level higher than the desktop operating system.

NETWORK OPERATING SYSTEM

Close Source Operating System (Proprietary) proprietary operating system is an operating system developed internally by a person, association or corporation. Classified as proprietary operating systems are Windows and Mac Os.

SOURCE CODE

Open Source Operating System (Open) Operating System Open an operating system source code is open to the public so that it can be developed by others. Including an open operating system is UNIX, Linux and derivatives.

Linux itself has many variants, such as Debian, Slackware, Redhat and SuSE. This variant is known as the distro.

SOURCE CODE

1. What is a network operating system?2. Mention network operating system known? 3. What is the difference between network

operating system with the operating system generally?

4. What are the advantages and disadvantages of using an open operating system (open source) than closed (proprietary)?

5. Describe the possibility of user applications to run directly without going through the operating system?
