Hardware refers to the physical devices connected to a computer, including external components like keyboards and internal components like motherboards. Software is a non-tangible set of programs that instructs the computer on its functions, divided into system software that manages overall operations and application software designed for specific user tasks. System software typically includes the operating system and device drivers, and it is usually pre-installed on computers.

1. HARDWARE
Hardware refers to a tangible device that is physically connected to the
computer system. Hardware components are connected to the computer
both externally and internally.
Devices that you can see outside your computer are called external
hardware, such as a as a keyboard, mouse, and printer; those that are
located inside the CPU cabinet are called internal hardware, such as a
motherboard, hard drive, RAM, etc
Software and its types
Software is a set of programmes that are designed for a well-defined
function. A programme is a series of instructions written to solve a
particular problem. Software is a non-tangible component of a computer.
It tells a computer ‘what to do’.
System software
System software is defined as a set of programmes that control the
overall operations and internal workings of a computer system. It
functions as a bridge between the hardware components and software of
a computer.
In other words, system software is a special software that manages and
supports computer resources; it includes the operating system, device
drives, and language translator. System software is almost pre-installed
on every computer.

2. Application software
Application software is a set of one or more programmes designed to
carry out operations for a specific purpose desired by the end user, like
creating and editing.
