Nature and privilege Operating System

Once we know the definition of the operating system now we Cont introduction to the nature and system privileges operasi.Ok friend, there are some properties and features of the operating system are derived and adopted from the UNIX operating system.Nature and privilege operating system, namely:

    Portability
    MultiUser
    Multitasking
    A hierarchical file system
    Utilities
    Shell UNIX / LINUX (Other)
Companions, in addition to the terms above we know that is the nature and privileges of the operating system, we are also required to know the understanding of each of these terms. To know the sense of each term directly to the scene that we friend.

Portability means ketidakbergantungan on a hardware users possible it does not need to rely on a single vendor and easily adapted to other computer systems. The following table illustrates the comparison of the operating system with the device may hard.
Multiuser means that a number of people (users) can use the system simultaneously and share resources (disks, printers, and so on). The advantage with the multiuser nature:• Saving perangat hardHardware (eg printers, disks) can be used by manyusers.• Data can be accessed by multiple users simultaneouslyThis means no copying of data, addition of data consistencymore secure.
Multitasking: A user can perform multiple jobs at the same time from a terminal. Jobs that do not require user interaction (as do the data sorting and checking vocabulary) can be carried out in the background. This enables the processing time of a job is being executed by the system, the user can perform other tasks. Ynag operating system capability allows one to carry out multiple tasks at the same time is called multitasking.
Hierarchical file system that allows users to organize information or data in a form that is easy to remember and easy to access. The information that can be set per user or instance grouped by department.
Utility: Operating system is composed of a number of programs, which include several utilities. Utilities utility has bermacammacam task, among others, relate to:• File Management• File Editor• Supporting communication• Supporting the development of softwareBy combining existing utilities, the user can create a new program to carry out the task as expected. This can be done quickly and easily.
Shell UNIX (LINUX) as a bridge between the user and the system. It acts as a command interpreter that is very useful for users. The ability of the shell includes two things:• Interactive mode and• programming mode.In interakif mode, the user can give commands and then shell will do the orders given. It can diulangulang. Because once the shell has finished running the commands, the shell will wait for the user giving the command again. In programming mode, the user can compile a program in the form of a number of commands commonly called shell scripts. Furthermore, the shell will do these commands in sequence. Things like this are very useful for handling work that is routine. In this mode the user can create a prototype of an activity without having to use a programming language such as C. In both interactive and programming mode, the user can easily direct the command outputs are normally to the layer to a file. Even the user can also set the result of a command into the input for another command.
