There are various input devices that can be used with a computer. The most common input devices are the keyboard and mouse, but there are also other devices such as scanners, digital cameras, joysticks, and gamepads. Each of these devices has its own specific function and can be used to perform different tasks.

1. Keyboard

The keyboard is perhaps the most essential input device for a computer. It is used to enter text, numbers, and other characters into the computer. A keyboard typically has around 101 keys, which include the alphanumeric keys, function keys, arrow keys, and special keys such as the Shift, Ctrl, and Alt keys.

2. Mouse

A mouse is another common input device that is used to control the cursor on a computer screen. A mouse typically has two buttons, the left button, and the right button, as well as a scroll wheel. The left button is used to select items, while the right button is used to open menus and perform other functions. The scroll wheel can be used to scroll up and down on a page or document.

3. Scanner

A scanner is an input device that is used to scan pictures or text into a computer. Scanners come in both flatbed and handheld models. Flatbed scanners are larger and can scan both text and images, while handheld scanners are smaller and can only scan text.

4. Digital Camera

Digital cameras are input devices that can be used to take pictures or videos and store them on a computer. Digital cameras typically have a USB port that can be used to connect the camera to a computer.

5. Joystick

Joysticks and gamepads are input devices that are used to play video games. Joysticks typically have one or more buttons, as well as a joystick that can be moved in different directions. Gamepads usually have several buttons, as well as a directional pad that can be used to control movement in a video game.

6. Microphones

Microphones are input devices that convert sound waves into electrical signals. We use the microphone to record sounds, voicemails or talk to the person over calls, etc.

Wrap Up

Input devices allow humans to interact with a computer. There are many different types of input devices, but the three most common are the keyboard, mouse, and touch screen. Other popular input devices include trackballs, joysticks, and digital pens. -Each type of input device has its own strengths and weaknesses. For example, the mouse is good for precise movements while the keyboard is good for typing text. -Touch screens are becoming more popular because they are easy to use and work well with tablets and smartphones. However, they can be difficult to use with laptops because they tend to be smaller than desktops.

It’s important to know the components of your computer hardware and how they work together because they are what enable you to do all of the things you love on your computer, like playing games, browsing the internet, and watching videos. Without computer hardware, there would be no computer. So next time you’re using your computer, take a moment to think about all of the stunningly designed hardware that makes it possible.

There are basically two types of hardware components.

• Internal hardware components
• External hardware components

What is Internal Hardware Components?

The internal hardware components of a computer include the motherboard, CPU, RAM, hard drive, and optical drive.

• The Motherboard is the main circuit board in the computer and it houses the CPU, RAM, and other important components.
• CPU (Central Processing Unit) is the “brain” of the computer and it executes all of the commands that you give to the computer.
• RAM (Random Access Memory) is a type of memory that is used to store data temporarily.
• A Hard drive or SSD (Solid State Drive) is where all of your files and data are stored permanently.
• Power Supply (SMPS) Used to supply all other components with power (electricity) converted from the outlet.
• The Optical drive is used to read and write CDs and DVDs.
• Video Card (GPU) is used for processing images and videos and renders graphical input to project it as an output to display devices (monitor).

What is the External Hardware Components?

External hardware components are those that are not an integral part of the computer itself and are usually added later. Those would include the printer, mouse, keyboard, monitor, headphones, and microphone. Some of these (monitor, keyboard, and mouse) interface directly with the user while others (printer, headphones, and microphone) interface with other devices or applications.

All external hardware components require additional external power in order to function properly.

All external hardware components must also be compatible with both the computer itself and any other external hardware components that may be attached. For example, a printer must be compatible with both the computer and the type of paper being used. A microphone must be compatible with both the sound card and the recording software.

A common list of external hardware components is used with a computer.

• Mouse
• Keyboard
• Display monitor
• Speakers
• Microphone
• USB flash drive
• Printer
• Scanner

Difference between Hardware vs Software?

When it comes to computers, there are two main types of components: hardware and software.

It’s very important to understand when learning about computers. This is because both work together in order for a computer to function properly. It is important to note that without either component, a computer would not be able to run. Therefore, the difference between Hardware vs Software becomes an important topic when discussing computers.

• Hardware refers to the physical parts of a computer, such as a monitor, keyboard, and drive. In contrast, the software is a set of instructions that tells the hardware what to do.
• The operating system is a prime example of software. The difference between Hardware vs software can be simply explained as Physical components are called hardware whereas Instructions are called software. Another difference between Hardware vs software is that you can physically touch hardware but you cannot touch software.
• The difference between Hardware and software is quite significant as one deals with physical components while the other deals with a set of instructions. Hence we can see that the Difference between Hardware vs software is that one is an intangible component while the other is a tangible component.
• The Difference can be further elaborated by saying that without hardware, the software cannot be used however without software, hardware can still be used though it will not serve any purpose.
