Computer Software Computer Program
Definition: Computer Software is a program which consists of specific line of codes/ instruction, which a computer machine execute in order to access dedicated hardware and process desired result/ task. Examples – Word Processor, Antivirus software, device driver software, BIOS software, email, internet Brower etc. The physical components of a computer are the hardware and the digital programs running inside hardware are the software. The Software can be updated or replaced much easier than hardware device. Likewise, software can be distributed to a number of hardware recipients.
Who Wrote the First Software in Computer Industry?
The answer is Ada Lovelace. She was the first Programmer who wrote an algorithm for analytical engine developed by Charles Babbage.
Types of Software
The Computer software is mainly divided into three equivalent programs namely – System Software, Application software and Malicious Software. It is divided on the basis of Purpose and Uses of software or program.
- System Software – The software or program which directly Control or execute the basis functionalities of hardware which are needed by a computer user. The best example such as an operating system, which enables other software to run properly, by interfacing with hardware and with other software. Alternately – System software refers to the files or programs that manages your computer’s operating system. System files like libraries of functions, system services, drivers for printers and other hardware, system preferences, and other configuration files are controlled by operating system. The programs which are part of the system software include assemblers, compilers, file management tools, system utilities, and debuggers.
Application software – A complete software which perform a specific task other than system oriented or maintenance functional tasks. The best example is a database programs, antivirus software, word processor software etc. Alternately – A software which is built to help the user to perform specific tasks is called application software.
Malicious Software – Malicious software is a program or file that are harmful to a computer system. Malware contains computer viruses, worms, Trojan horses and spyware. These malicious programs can perform many illegal functions like stealing, encrypting or deleting sensitive data, altering or hijacking core computing functions and monitor users computer activity without his/her permission.

Other Information regarding Software/ Program:
All programs and applications for computers are a set of instructions designed to create particular result. A computer program is a collection of all instructions that have a common purpose. A collection of programs to carry out coordinated friendly related tasks is referred to as a package. One good example of a package of software programs might be an application that handles accounts related tasks. Such a package would have a number of modules, or independent programs, that function together to create a complete package.
Today all computers operate with the help of system software, or say operating system. This programming provides the very basic instructions to the user how the computer interacts and how the various programs and packages operates easily. If you have to do some task on computer system then there are at least three components which contribute their part to accomplish the task. The hardware, Software and Operating System.
