Computer Hardware and Software Questions and Answers

In general notion, any computer system can be broadly divided into two categories: Hardware and Software. Hardware represents the physical and visible components of the system such as a monitor, CPU, keyboard, and mouse. Hardware is physical in nature and hence one can touch and see hardware. Software, on the other hand, represents a set of instructions that enable the hardware to perform a specific set of tasks. The software cannot be physically touched but still can be used and seen. The software must be present in the hardware to function efficiently and similarly, the hardware must be present for the tasks to be executed. Both are interdependent, yet they are also different from each other.

Difference between Hardware and Software

Hardware represents the physical and visible components of the system such as a monitor, CPU, keyboard, and mouse. Hardware is further divided into four main categories: Input Devices, Output Devices, Secondary Storage Devices Internal Components. Software, on the other hand, represents a set of instructions that enable the hardware to perform a specific set of tasks. Software is further divided into two main categories:
Application Software, System Software. The software must be present in the hardware to function efficiently and similarly, the hardware must be present for the tasks to be executed. Both are interdependent, yet they are also different from each other.
