3. Outputting

*Outputting is the third basic operations of computer. In simple language, outputting means, the result of instruction given by a user is called output.

*Whatever input is given by the user computer, then the output result of that input is outputting.

*Input/output devices are responsible for the computer's interaction with the physical world.

*For instance, a keyboard or mouse are input/output devices.

*They are responsible for responding to your commands and providing feedback.

*The computer needs these components to provide output, which is information that comes out of the system.

*This includes visual feedback like video or text, as well as audio feedback like sound or music.

*HW is made up of all the physical components that define how your PC operates - it is what allows you to interact with your PC in some way.

*HW could include your keyboard, mouse, microphone, or speakers.

*These are all hardware pieces that allow you to use your computer in some way.

*SW is made up of everything on your screen - everything from Microsoft Word to Spotify - and it is what allows you to interact with those programs on your computer.

*SW could include Microsoft Office or an online game like Candy Crush Saga.

*Combined, HW and SW make up the "operating system" (OS) of your computer because they're what makes it function correctly and work with each other.

*The OS ( Operating system ) allows input devices like keyboards and mice to work with output devices like monitors; this means you can control what happens on screen by typing on a keyboard or moving a mouse around!

*You also need drivers (software) for both HW and SW so they will communicate properly; without drivers installed, you won't be able to do anything.

Note - Without using an output device, you cannot get the output result of any input data. You have to use an output device to get the output result.

*Examples of output devices are :

• Monitor
• Printer
• Headphones
• Computer Speakers
• Projector
• GPS (Global Positioning System)
• Sound Card
• Video Card
• Braille Reader ( A braille reader, also called a braille display, is an electronic device that allows a blind person to read the text displayed on a computer.)

• Speech-Generating Device

4. Storing

*Storing is the fourth basic operations of computer system. 

*In simple language, storing means, the output result that comes after executing the instruction given by a user, and storing that output result is called storing.

*The CPU is responsible for storing data in your computer's memory, which is where the data is stored when you type it into a word document or open an image.

*The CPU processes this data to make it easier to retrieve. Processors are the components that are responsible for executing applications that are stored in your computer's memory.

*These processors can be found on the motherboard and can vary depending on the PC’s specifications.

*When you save a file, you are copying it from random access memory onto a storage device like an external hard drive, CD/DVD, or flash drive.

*When you save a file to your computer's hard drive, you're always saving two copies of the original file - one copy in its original location and one backup copy in another location.

*This redundancy ensures that if something happens to the first file - say by accident deletion - then there is another copy of it somewhere else on your hard drive.

*There are various types of storage device, which are given below.

• Hard Disk Drive ( HDD )
• Floppy Disks
• Tapes
• Compact Discs (CDs)
• DVD and Blu-ray Discs
• USB Flash Drives
• Secure Digital Cards (SD Card)s
• Solid-State Drives (SSD)
• RAM
• ROM
