Introduction to Hardware and Software
Let us understand the difference between hardware and software with the help of our body. Our body is hard and we can touch it, move it but what about our feelings? We cannot touch our feelings. Computers are also made in the same way. It consists of two parts, one is hardware and another is software. One without the other is of no use. To run a computer both hardware and software are necessary. Hardware is the part that you can see and touch, parts which cannot be touched are called Software.
Physical parts of Computer (Hardware)
Hardware refers to the physical components of the computer that run the software such as the hard drive, motherboard, video and sound cards, monitor, printer, keyboard and mouse.
Logical parts of Computer (Software)
Software is a collection of code and instructions that tell a computer and/or hardware how to operate. Software is a set of programs that you install on your computer to help us to do different kinds of work including Games, Word Processing programs, WordPad, Notepad etc.
Relationship Between Hardware and Software
There is a close relationship between computer hardware and software. If hardware is the body, then software is just like the soul in a body. Just as the body cannot live without the soul, the computer cannot perform without software.
Software is code and instructions that tell a computer and/or hardware how to operate. This code can be viewed and executed using a computer or other hardware device.
