So let's Start....! 
Our First Topic is Computer Hardware.
Computer Hardware :
"Computer hardware is the collection of physical parts of a computer system. This includes the computer case, monitor, keyboard, and mouse. It also includes all the parts inside the computer case, such as the hard disk drive, motherboard, video card, and many others. Computer hardware is what you can physically touch."
Explanation of Computer Hardware:-
A computer system has three main components. 
1 : Hardware
2 : Software
3: User(People)
First of all What is Hardware?
The Equipment Assosiated with the computer is know as Hardware. In  simple words "hardware are the components of the computer system which are touchable. IT's mean we can touch the hardware".  
Second is What is Software?

Third is What is People?
People(USer) are the persons who use the computer hardware and software. In business User often called End-users. The use the true capabilities of the computer system. 
Computer has many hardware
Now we'll discuss about compute hardware components
Keyboard 
keyboard is the set of typewriter-like keys that enables you to enter data into a computer and other devices. Computer keyboards are similar to electric-typewriterkeyboards but contain additional keys. ... The standard layout of letters, numbers, and punctuation is known as a QWERTY...
Mouse 
computer mouse is an input device that is most often used with a personal computer. Moving a mouse along a flat surface can move the on-screen cursor to different items on the screen. Items can be moved or selected by pressing the mouse buttons (called clicking).
Hard disk drive
A hard disk is part of a unit, often called a "disk drive," "hard drive," or "hard disk drive," that stores and provides relatively quick access to large amounts of data on an electromagnetically charged surface or set of surfaces. Today's computers typically come with a hard disk that contains several billion bytes (gigabytes) of storage.
