What is software?

• The program used in a computer
• a set of instructions for the computer to carry out task.

Computer software, or just software is a general term primarily used for digitally stored data such as computer programs and other kinds of information read and written by computers. -Wikipedia-

Software is a collection of instructions that enables a user to interact with the computer or have the computer perform specific tasks for them. Without any type of software the computer would be useless.

System Software

System software is use to control the computer or hardware.

• it is where you save the data
• control the hardware
• install or run other programmes
  

It includes the combination of the following :

• device drivers
• operating systems
• servers
• utilities
• windowing systems

The purpose of systems software is to unburden the applications programmer from the often complex details of the particular computer being used, including such accessories as communications devices, printers, device readers, displays and keyboards, and also to partition the computer's resources such as memory and processor time in a safe and stable manner.

Example : Microsoft Windows XP, Microsoft Windows Vista, Linux, OSX (AppleMac)

Application Software

Application software is to do a specific and to solve problems. It is a subclass of computer software that employs the capabilities of a computer directly and thoroughly to a task that the user wishes to perform.

There are two types of software :-

1. Ready made (off-the-shelf) software
2. User-written software
   

Ready Made software

• display on shelf
• less error
• fully tested
• cannot modify
• cheaper

User Written software

• overlooked by programmer
• more expensive because may hire specialist
• may contains more error
• can request some special features
• programmer can create their own program using this

Advantages of using ready made packages :

1. An important advantage is that users do not need any special technical skills or ability to use them. Designed to be user-friendly.
2. They cost much less than writting your own software.
3. They are easily available. It is buy what you want.
4. Suitability of the computer.

Disadvantages of using ready made packages :

1. They are rigid and their functions cannot be changed.
2. Some of them may not suit your specific requirements.
