Main Parts Of Computer And Their Functions – Computers have changed the way the world works, from complex computing to entertainment, it has it all. Computers are very important in this technological era and with the rise of digitalization, computers are now everywhere. But these computers are made up of certain important components, and without them they are meaningless. One of the most important components of these computers are the input and output devices. Here in this article, we have discussed in detail the input devices of computers along with input device definitions, examples and much more.

An input device is a computer device or hardware that allows a user to provide data, input, and instructions to a computer system. Data is transferred to a computer system in a raw format, which is then converted by input devices into a language that the computer can understand. The CPU then processes the data to produce output. In other words, an input device is a kind of peripheral device that helps users interact with a computer system.

Main Parts Of Computer And Their Functions

Hardware devices are used to provide instructions or transmit data to computer systems. The instruction or data inserted during this process is called Input and the device used to input the data is called computer input device. These computer input devices can be classified into various categories such as pointing devices, keyboard devices, drawing devices, recognition devices, etc. Some of the commonly used input devices are:

What’s Inside Your Computer Cabinet (cpu Box)?

An input device helps a user send data, information, or control signals to a computer system. The central processing unit (CPU) of a computer system receives input data and processes it to produce output data. Now that we know what input devices are and their definition, give us some examples of input devices. Here in this section, we have discussed in detail some of the input devices and the tasks they perform.

Keyboards are one of the basic input devices that help in entering data and commands into a computer or any electronic device by pressing keys. The keyboard has a different set of keys for letters, numbers, functions and symbols. The keyboard connects to the computer system via a USB cable (for a wired keyboard) or via Bluetooth (for a wireless keyboard). Most keyboards come in two sizes: 84 keys or 101/102 keys, but many brands now make 104 or 108 key keyboards for Windows.

Laptops come with a built-in keyboard, which makes the laptop smaller and lighter. While most of the modern devices like smartphones, tablets, etc. come with on-screen virtual keyboards that help you enter data into the computer. Before keyboards were invented, paper tapes and paper cards were used to transmit instructions to computers.

A mouse is a widely used input device that helps a user interact with a computer system through a process called point-and-click. This handheld input device is used to move a cursor or pointer around the screen. It operates on a flat surface and has left and right buttons with a wheel in between to perform tasks. The left button helps you select items, and the right button helps you display menus. The wheel between them helps you scroll up and down the page while surfing or reading documents.

Basic Computer Parts And Functions

Laptops are equipped with a built-in touchpad that functions as a mouse. You can control the cursor movement on a laptop by sliding your fingers over the touchpad.

A joystick is also a pointing device, similar to a mouse, that is widely used for playing games on a computer. Joysticks consist of a joystick with a spherical base, the base of which is inserted into a socket that allows the joystick to move freely. The cursor or pointer on the screen is controlled by moving the joystick.

C.B. Mirick invented the first joystick at the US Naval Research Laboratory. Joysticks come in different types such as movement joysticks, finger joysticks, hand-held joysticks, isometric joysticks and many more. The main difference between a joystick and a mouse is that in a joystick, the cursor continues to move in the direction of the joystick unless it is in a vertical position, whereas in a mouse, the cursor moves only when the mouse moves.

A light pen is a computer input device that looks like a pen. A light pen is a very sensitive device and consists of a photocell and an optical system housed in a small tube. The tip of the light pen also contains a light-sensitive detector that allows the user to point or select objects on the display screen. These devices are mainly used for selecting items on the screen, drawing pictures, and freely entering document files using the computer screen. When the tip of the light pen moves across the computer screen by pressing a button on the pen, corresponding signals are sent to the CPU. The first light pen was invented around 1955 as part of the Whirlwind project at the Massachusetts Institute of Technology (MIT).

Input Devices Of Computer: Definition, Examples, Images

A microphone or “microphone” is a type of input device that helps a user input voice into a computer system. Microphones read sounds from the environment and then convert analog sound waves into electrical signals. The microphone receives sound vibrations and converts them into sound signals or sends them to the recording medium. Audio signals are also converted into digital data and then stored in a computer. The microphone helps the user communicate with other people. Sounds can be added to presentations and webcams for video conferencing using microphones.

A scanner is an important input device that helps us convert a paper document into a digital file (.jpeg, .png, .pdf, etc.). The technology behind a scanner is called optical technology, which basically reads characters or images from paper and transfers them to the computer disk for further processing. The scanned image can be further edited, printed, emailed, etc. There are different types of scanners available that perform different functions. Some common examples of scanners are photo scanner, flatbed scanner, drum scanner, sheet-fed scanner, etc.

Digital cameras are input devices that record images (and sometimes video) digitally. Instead of film, digital cameras use an image sensor chip to capture images. The first step in using a digital camera as an input device for a computer is to connect it to it. This can be done using a USB cable, a memory card reader, or a wireless connection. Using photo editing software or a file manager, you can transfer images and videos from your camera to your computer.

Answer. An input device is a computer device or hardware that allows a user to provide data, input, and instructions to a computer system. Data is fed into a computer system in a raw format, which is then converted by input devices into language that the computer can understand.

Answer. 10 Examples of Computer Input Devices: Keyword, Mouse, Joystick, Light Pen, Microphone, Scanner, Digital Camera, Trackball, Barcode Reader, and OCR. The main parts of a desktop computer are the computer case, monitor, keyboard, mouse, and power cord. Each part plays an important role when using a computer.

The computer case is a box made of metal and plastic that contains the main components of the computer, including the motherboard, central processing unit (CPU), and power supply. The front panel of the case usually has an on/off button and one or more optical drives.

What Is Computer Hardware?

Computer cases come in different shapes and sizes. A desktop case sits flat on the table, with the monitor usually placed on top. The tower case is tall and is installed next to the monitor or on the floor. All-in-one computers come with the internal components built into the monitor, eliminating the need for a separate case.

The monitor works with a video card located inside the computer case to display images and text on the screen. Most monitors have control buttons that allow you to change the monitor’s display settings, and some monitors also have built-in speakers.

Newer monitors usually have LCD (liquid crystal display) or LED (light emitting diode) displays. They can be made very thin and are often called flat panel displays. Older monitors use CRT (cathode ray tube) displays. CRT monitors are much larger and heavier and take up more desk space.

The keyboard is one of the main ways to communicate with a computer. There are many different types of keyboards, but most of them are very similar and allow you to perform the same basic tasks.
