WHAT IS SOFTWARE

SOFTWARE

 Software,It  is a collection of data or computer instructions that tell the computer how to work. This is in contrast to physical hardware, from which the system is built and actually performs the work. In computer science and software engineering, computer software is all information processed by computer systems, programs and data. Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media. Computer hardware and software require each other and neither can be realistically used on its own .

THERE ARE MANY TYPES OF SOFWARE

1.SYSTEM SOFTWARE

2.APPLICATION SOFTWARE

3.UTILITY SOFTWARE 

 

 

SYSTEM SOFTWARE

IT IS USER FRINDLY 

e.g- MEDIA PLAYER,MUSIC PLAYER,CALCULATOR,etc

UTILITY SOFTWARE 

UTILITY SOFTWARE IS ALSO A TYPE OF SOFTWARE .WHICH IS USED TO MANAGE

OR UTILISE THE OPERATION PROCESS IN THE SYSTEM IT IS ALSO KNOWN AS DRIVER 

WHICH PERFICTLY PERFORM OPERATIONS OR FOLLOW THE USER COMMAND CORRECTLY
