Software vs. Hardware
Knowing the distinction between software and hardware is basic knowledge in information technology.
What Is Hardware?
A hardware component is the physical aspect of the computer—referring to the part you can see, feel, and handle. The hardware layer acts as the base component of any computing machine and is the basic necessity in the process of making any software function.
Some common examples of hardware include:
- CPU (Central Processing Unit): The “brain” of the computer that does math and carries out instructions
- Monitor: This is responsible for showing all visual information from the computer
- Keyboard and Mouse: The input devices used for interaction with the system
Hard Drives and SSDs
Storage devices where data as well as software are stored
Printers & Scanners
Peripherals that allow the printing and scanning of documents. If the hardware was not present, the software would not be able to run. Therefore, hardware is an integral part of every information technology system.
What is Software?
Software: This refers to a collection of programs, commands, and data used by computer hardware to perform tasks. The uniqueness of software compared to computer hardware is the fact that software consists of intangible components, which cannot be touched.
Typical examples of software include:
- Operating Systems: Windows, Linux, macOS, Android
- Application Software: MS Word, browsers, mobile applications, and design and accounting software
- System Software & Utilities: Device drivers, Antivirus Software, Backup Software, Maintenance Software Functionally, hardware refers to the body, while software refers to the brain because it is responsible for instructing the system on how it is supposed to function.
Key Differences Between Hardware and Software
Nature
Hardware: Physical components that can be seen and touched
Software: Intangible programs and instructions
Functionality
Hardware: Cannot operate on its own without software
Software: Cannot run without hardware support
Durability
Hardware: Can wear out or get damaged over time
Software: Does not wear out physically but can be updated or upgraded
Modification
Hardware: Changes usually require physical replacement
Software: Can be easily modified, updated, or reinstalled
Abstracting Hardware and Software
In information technology, abstraction is the act of hiding the complex details of the technology and revealing the minimum requirements that are needed to be accessed.
Hardware Abstraction
Hardware abstraction makes it possible to use computer software with hardware without the software being aware of the internal workings of the hardware. One important role is played by the Operating System (OS) which works as an interface between hardware and applications.
Examples:
- Applications do not require knowledge of the internal workings of the hard drive or processor.
- The Operating System deals with the management of resources like CPU usage, memory, storage, as well as input/output devices.
Software Abstraction
Software abstraction enables developers to develop using high-level tools rather than low-level machine code. This enables faster development as well as simplifies the development process.
Examples:
- APIs (Application Programming Interfaces)
- Libraries and frameworks
- Virtual machines and containers
- Why Abstraction Is Important
- Simplifies system design and usage
- Improves scalability and security
- Enables faster development and innovation
- Makes IT systems easier to maintain and upgrade
In short, abstraction is a core concept that makes modern IT systems powerful, flexible, and developer friendly.
