Computer software is a general term that describes computer programs. Related terms such as software
programs, applications, scripts, and instruction sets all fall under the category of computer software.
Therefore, installing new programs or applications on your computer is synonymous with installing new
software on your computer.
Software can be difficult to describe because it is “virtual,” or not physical like computer hardware.
Instead, software consists of lines of code written by computer programmers that have been compiled into a
computer program. Software programs are stored as binary data that is copied to a computer’s hard drive,
when it is installed. Since software is virtual and does not take up any physical space, it is much easier
(and often cheaper) to upgrade than computer hardware.
While at its most basic level, software consists of binary data, CD-ROMs, DVDs, and other types of media
that are used to distribute software can also be called software. Therefore, when you buy a software
program, it often comes on a disc, which is a physical means of storing the software.
Shortly:
Software:
Computer required a number of instructions to do any job. The set of these instructions forms programs.
Numbers of programs are combined for some purposes are called software.
They are designed by manufactures and programmers.
Types of Software
1. System Software
2. Application Software
System Software:
System software refers to the files and programs that make up your computer’s operating system. System files include libraries of functions, system services, drivers for printers and other hardware, system
preferences, and other configuration files. The programs that are part of the system software include
assemblers, compilers, file management tools, system utilites, and debuggers.
The system software is installed on your computer when you install your operating system. You can update the software by running programs such as “Windows Update” for Windows or “Software Update” for Mac OS X. Unlike application programs, however, system software is not meant to be run by the end user. For example, while you might use your Web browser every day, you probably don’t have much use for an assembler program (unless, of course, you are a computer programmer).
Since system software runs at the most basic level of your computer, it is called “low-level” software. It
generates the user interface and allows the operating system to interact with the hardware. Fortunately, you
don’t have to worry about what the system software is doing since it just runs in the background. It’s nice
to think you are working at a “high-level” anyway.
Application Software:
Application software is the name given to the programs that perform specific tasks for users. For example,
games, instant messengers, word processors, and antivirus programs are all applications.
programs, applications, scripts, and instruction sets all fall under the category of computer software.
