    SOFTWARE BASICS.

    Software can be define as the untouchable part of the computer, it is also the ghost in the machine and it can be known as the computer's instruction or data. Applications that can be stored on the computer system electronically is know as software, in contrast to storage devices and display devices.
    Types of software;-
    Software is often divided into two categories
    1. Operating system
    2. Application system
    Types of system software:
    The major types are:-
    *Operating system,
    *Translators,
    *Utilities, and
    *Device.
    The main propose of operating system is that it defines an abstraction of hardware behavior with which programmer can control the hardware. An operating system can also be shared by other computer users. In addition, this system is an interface between hardware and users which manages and coordinates the activities and the sharing of the resources of the of the computer.

    Roles of an operating system: An operating system commonly abbreviated as O.S is an interface between hardware and application. It is also responsible for the management coordination of activities and the sharing of the limited resources of the computer. The operating system acts as a host for application that are run on the machine. As a host one of the propose of an operating system is to handle the details of the operating of the hardware. This relieves application program from having to manage these details and makes it easier to write application. Almost all computers, including, handheld computers, desktop computers, super computers and even video game consoles use an operating system of same type. Some of the oldest models may however use an embedded operating system, which may be contained on a compact disk or other data storage device.

    Characteristics of Operating System:
    *file and folder interface,
    *control hardware access,
    *automatically discovers, and
    *configures adjacent hardware.

    Comparing operating system;
    *Runs single-user applications,
    *Unix,
    *Fedora,
    *Ubuntu, and
    *Debia,
    *Microsoft windows,
    *windows XP,
    *Macintosh imacosx,
    *Unix
    They support a single user, Share file and folder on a small network with limited security, they have common hardware upgrades, Pam capacity, Video card memory and speed, Hard device size, Processor speed. Most Operating System have Hardware Compatibility List (h c l).
    In conclusion software refers to all programs which can run on all computer system. Its the main part of the computer which a computer can never do away with.
