SOFTWARE
SOFTWARE – the general term for computer programs and applications
Computer software provides instruction that tell the computer how to operate.
Software are also called programs.
Programs are usually created using other software called programming languages.
THERE ARE TWO (2) MAIN TYPES OF SOFTWARE
1. System Software
Used by the computer to accomplish a task.
acts as an interface between hardware and application software
What system software does:
*controls the internal function of the computer
*controls other devices connected to the CPU
2. Application Software
Used by people to accomplish a specific task.
Some common kinds of application software
*Word Processor software
*Database software
*Spreadsheet software
*Games
*Web Page Browsers
SYSTEM SOFTWARE is any computer software which manages and controls computer hardware so that application software can perform a task. Operating systems, such as Microsoft Windows, Mac OS X or Linux, are prominent examples of system software. System software contrasts with application software, which are programs that enable the end-user to perform specific, productive tasks, such as word processing or image manipulation.
Operating Systems
1. The operating system is usually located on a disk.
2. Used by the computer's hardware to work with its parts.
Tells the computer how to:
§ display information on the screen.
§ use a printer.
§ store information on a secondary storage device.
3. An operating system works with application software.

3. An operating system works with application software.
Does basic tasks, like printing a document or saving a file
The operating system starts (launches) the application software so that it can be used.
The operating system is the core software component of your computer.
It performs many functions and is, in very basic terms, an interface between your computer and the outside world. In the section about hardware, a computer is described as consisting of several component parts including your monitor, keyboard, mouse, and other parts. The operating system provides an interface to these parts using what is referred to as "drivers". This is why sometimes when you install a new printer or other piece of hardware, your system will ask you to install more software called a driver.
Drivers - the system software that controls computer peripherals
A driver is a specially written program which understands the operation of the device it interfaces to, such as a printer, video card, sound card or CD ROM drive. It translates commands from the operating system or user into commands understood by the component computer part it interfaces with. It also translates responses from the component computer part back to responses that can be understood by the operating system, application program, or user.
APPLICATION SOFTWARE are programs that are working with the operating system software to help the computer to do specific types of work such as word processing to type a letter.
1. Used by people to solve general problems
Can be used to do more than one thing - adapted to a wide variety of tasks
Some common tasks done by general purpose application software
Planning
Writing
Record keeping
Calculating
Communicating
Drawing
Painting
What can be done with general purpose application software is only limited by the
imagination of the user.
2. Examples of general purpose application software
*Word Processing Software
*Database Software
*Spreadsheet Software
*Desktop Publishing Software
*Paint and Draw Software
UTILITIES allow you to complete certain tasks on your computer. Examples of some of these tasks are file organizations.
Specific purpose application software used to help a computer work better or to avoid
problems.
Some utility programs are built into the operating system
*Scandisk in the Windows operating system
*Disk formatting software
Examples of utility programs
*Anti-virus software
*Disk maintenance software
File management programs
Security software
PROGRAMMING LANGUAGES - used to facilitate communication about the task of organizing and manipulating information, and to express algorithms precisely.
