Relationship between Hardware and Software
Relationship between Hardware and Software
Hardware and Software Relationship
- Hardware refers to the tangible or physical components of a computer system.
- Software, on the other hand, represents the collection of programs that instruct hardware to perform tasks.
- An intimate relationship exists between hardware and software as neither can work without the other.
Role of Hardware
- Hardware is designed to carry out computations and tasks but it cannot do so without instructions from software.
- Loved by gamers, Graphics Processing Units (GPUs) need software (games themselves and drivers) to utilise their raw computing power.
- Central Processing Units (CPUs) need a compatible operating system and applicable software to perform calculations and process information.
- Peripheral devices, such as printers or scanners, require appropriate software drivers to function properly with a computer system.
Role of Software
- System software coordinates and controls hardware functionality. The operating system (OS) is an essential part of system software that manages computer hardware and software resources.
- Application software, often just called applications, refers to programs designed for end users. Such programs use an operating system (OS) and hardware to deliver their function.
- For instance, a word processing app heavily relies on the capabilities of the OS, CPU (processing), memory (storing document as you work), hard drive (long term storage), display (visualisation) and input devices (keyboard and mouse for interface).
Interdependence
- Hardware and software are highly interdependent. Without software, hardware is meaningless and without hardware, software has nothing to run on. They must cooperate together to execute tasks.
- For example, when a user requests to open an application, the OS (software) harnesses the CPU (hardware) to launch it.
Evolution
- With advances in technology, the relationship between hardware and software has become more cooperative rather than strictly hierarchical. New hardware often inspires new software development, and vice versa.
- Hardware upgrades often require corresponding software updates. This is evident in new generations of CPUs often necessitating updates to the OS.
- Virtualisation is blurring the lines between hardware and software as software is used to emulate hardware setups leading to greater flexibility.
Importance of Understanding Relationship
- As aspiring computer scientists, understanding the symbiotic relationship between hardware and software lets you diagnose and rectify system failures, design efficient systems, and predict future trends in technology.
Conclusion
- In summary, hardware provides the raw power and structure for the system while software tells the hardware what, when and how to accomplish tasks. A mutual understanding and communication exists that makes the functioning of a computer system possible.
