Computer Hardware

Computer runs with two basis:

1) Computer Hardware

2) Computer Software

Computer Hardware:

Hardware are those parts of computer which can be physically touched seen and cab be carried from one place to another(e.g)keyboard, mouse, monitor, CPU, printer, scanner. etc.

      Keyboard   

                                                                                keyboard is used to insert input(TEXT) data into computer.

 Mouse 

In computing, a mouse is a pointing device that detects two-dimensional motion relative to a surface. Means a mouse has a pointer which moves on screen and makes the work easy.

 Monitor 

A monitor or a display is an electronic visual display for computers. The monitor comprises the display device, circuitry and an enclosure. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size.

 CPU (Central Processing Unit)

                                                            CPU is the abbreviation for central processing unit. The CPU is the brains of the computer where most calculations take place.                                                            

Computer Software:  

Software is that part of computer that operates the hardware. Software cannot be touched like hardware. It is a written language of commands in programming which commands the hardware to perform a particular task. Computer Software is called the Operating System. because without a OS a computer does not run even cannot start. Software is usually written in programming language that are easier and more efficient for humans to use than machine language.

 

 

 

 

Computer

A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data. You can use a computer to type documents, send email, and browse the Web. You can also use it to handle spreadsheets, accounting, database management, presentations, games, and more. OR

In simple words a computer is an electronic device which takes  input process it and gives output. which mean when input is put through keyboard, mouse, scanner or any input device, the data is processed and by computer because the input data is raw then the output is given by computer by displaying it on moniter or any source.

Introducing my new Blog

Thanks for stopping by and welcome to my new blog! This is just an introductory post so I’ll keep it short and sweet.

I decided to start a blog because I [what inspired you start a blog?]

Over the next few months I plan to be writing and sharing posts about [what topics will you be writing about?]

That’s it for now! If you’d like to be kept updated with my posts “Like” this post or subscribe to my blog.
