Nowadays, software plays a significant role in defining how we generally interact with modern and innovative technologies. From using the devices to perform our day-to-day tasks to performing large sets of operations in any organization, the software serves as a platform to operate those devices and technologies to give various functionalities. But still, you need to know What exactly is software and Why software is very important.
With this blog, we basically have explained the fundamentals of the software, its types, and how the software works. Follow this blog and you will get a good understanding of software.
What is Software?
Software is a bundle of instructions, data scripts, and programs to perform a certain task function or operation that is commanded (what to do, how to do it, when to do it) by the user to a hardware device(PC/Computer/Laptop). In simpler words, the software serves as the intermediate platform that connects users with hardware.
Have a look below for a better understanding:
Every software is made to achieve a dedicated computational purpose. It makes the hardware useful for achieving the desired output of the user.
Software only understands a binary language which is (1 or 0) and it allows developers to instruct the device and make it perform the necessary required actions.
Why Do We Need a Software?
Our body is like a hardware device, our brain is like a CPU and software is like our soul. Without software, we can’t perform any activities to achieve the desired output of the user as we can’t instruct hardware devices directly.
Software is an important part of any system because it can improve efficiency, reduce errors, improve communication, improve reliability, improve security, improve scalability, improve training and support, improve cost-effectiveness, and provide a better user experience.
History of Software
In 1948, the first software was created by a mathematician and English scientist named Tom Kilburn. In the beginning, software was generally hardcoded in machines but as technology evolved computer languages like COBOL and FORTRAN were introduced in the 1950s and 1960s easing the software development process.
At the time of the 1980s, the software industry further grew and software was diversified into system software and application software. By the time of 1990s, the concept of open-source software comes into play boosting the software industry further. And Today, modern technologies like AI, SaaS, and cloud computing shaping the future of the software industry.
Working of Software
As mentioned earlier, Software generally acts as a translator or mediator between the user and hardware which results in effective and smooth interaction. Here we have discussed how these operations occur:
- User Input: The user typically provides input with the help of output devices like a keyboard, mouse, or voice input to the User Interface(UI) provided by the Software
- Instruction Interpretation: As software generally understands binary codes like 0 and 1, it then translates those instructions into machine-readable binary code.
- Hardware Communication: With the system software the information inputted by the user is passed to the hardware.
- Task Execution: Hardware Components like CPU or memory then execute those instructions and perform necessary operations like data processing and calculations.
- Output Delivery: At last, the software then processes the results generated by the hardware and shows that to the user in a properly formatted and User-friendly manner such as displaying the webpage, opening the menu bar, etc.
In fact, software development follows a very systematic approach called the Software Development Life Cycle, or SDLC. It basically ensures the requirement analysis, design, development, testing, deployment, and maintenance of the software to be efficient, scalable, secure, and meet the requirements of users.

Types of Software
There are mainly two types of Software:
- System Software
- Application Software
1. System Software
System software is useful for working or operating a computer system. It is responsible for managing all tasks on hardware devices and provides basic functionality for executing each application. It controls the device’s inner or internal functioning via an OS (Operating System).
It runs in the background to manage all the functions or operations to fulfill a specific task of the user. If we have not installed System Software, we can’t perform any task on our computer device (PC/Laptop/Computer).
Types of System Software
1. Operating System
An Operating System is a basic system software or program that is the interface between hardware devices (computer/laptop/mobile) and users. It provides a basic platform to run the application’s software or program. Without an OS application software doesn’t work. It manages application software and hardware and provides security to the users. Without it, software and hardware don’t work.
For Example: Windows, Linux, Unix, macOS, Android, iOS, CentOS, Fedora, etc.
2. Language Processor/Translator/Converter
A Language Processor/Translator/Converter can convert a human-readable means high-level language (C, C++, JAVA, and Python) i.e., a source code into an object code/machine-readable code/binary code means low-level language (Assembly) via a Translator which is understandable by the machine.
For Example: Assembler, Interpreter, Compiler, Debugger, Linker, Loader, etc.
3. Programming Software
Programming Software is used to write the programming code by using programming languages such as C, C++, JAVA, Python, etc. Developers develop software by writing code using these languages. Later, they test and debug their code with the help of a Compiler and Debugger.
For Example: Vs Code, IntelliJ, PyChram
4. Device Driver Software
A Device Driver software is an interface between the OS and hardware device. Overall, it manages how the device connects with your system (PC/Computer/Laptop) to perform the proper functioning of a specific hardware device. It is responsible for the control, management, and operation of a specific hardware device. It is one type of mediator between the OS and the attached device.
For Example: Mouse, USB, Printer, BIOS, ROM, Display, VGA, Motherboard, Sound Card, Mice, Modem etc. Basically, it is required when we want to connect any new device to our system (PC/Computer/Laptop), initially, we need to install the driver. So the OS knows how to manage or control that device.
5. Utility Software
Utility Software is used to maintain, configure, and manage the functionality of a computer system. Some Utility Software is inbuilt and comes with the OS such as memory management, administration tools, Input or Output management, etc.
Examples:- Antivirus, Compressional tools, defragmentation tool, formatting and restore utility, disk cleaner, etc.
Key Features of System Software:
- Foundation of System Operations: System Software is the heart of computer systems as it manages hardware and system resources.
- Background Operations: These system software runs continuously in the background to manage memory efficiently and perform process scheduling
- Low-Level Languages: They are created using low-level languages so that they can communicate with hardware efficiently
- Faster Speed: System Software is generally faster as it maintains efficient and optimal performance of the system.
- Crucial For Functionality: Without the system software, you will not be able to operate or use the device’s hardware or any application software.

Application Software is used to perform special functions for the end user’s requirement to accomplish. It is also known as an End-User/Productivity Program.
The main purpose of the Application Software is to fulfill the user’s task. It is executed over the OS. A desktop/Laptop application is known as a Desktop Application while whatever we’re using on a phone/mobile is known as a Mobile Apps. Software developers create an application based on the user’s needs.
Types of Application Software :
1. General Purpose Software
General Purpose Software is used for generic purposes to perform different tasks for larger people in general instead of a specific task. Those are ready-made software that is used by end users as per their needs. General Purpose Software is also known as “Packages”.
Examples: MS Office (Word, Excel, Powerpoint), Google Drive, Adobe Photoshop, GIMP, Mozilla Browser, iTunes.
2. Special Purpose Software/Customized Software
Special Purpose Software or Customized Software is used to perform a specific task design or function for a specific organization or an individual.
Examples: School Management Software, Accounting Software, User Defined Software, Railway Reservation System Software, Airline Reservation System, Invoice Management, HR Management Software, Inventory Control System Software (Stock Control System), Billing System Software, etc.
Key Features of an Application Software :
- End-User Target: Application software is typically designed to perform day-to-day tasks requested by the user like web browsing, image editing, media consumption, etc.
