PART OF COMPUTER

 PART OF COMPUTER :-

 INTRODUCATION:- 

The basic parts of a desktop computer are the monitor, keyboard, mouse, printer ,speaker ,ups CPU(central processing unit)  and power cord ups. Each part plays an important role whenever you use a computer.

PARTS OF COMPUTER
(PC)

                         (1) MONITOR

A computer monitor is an output device that displays information in pictorial or text form. A monitor usually comprises a visual display, some circuitry, a casing, and a power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) with LED backlighting having replaced cold-cathode fluorescent lamp (CCFL) backlighting. Previous monitors used a cathode ray tube (CRT) and some Plasma (also called Gas-Plasma) displays. Monitors are connected to the computer via VGA, Digital Visual Interface (DVI), HDMI, DisplayPort, USB-C, low-voltage differential signaling (LVDS) or other proprietary connectors and signals.

MONITOR

                 USE OF MONITOR:-

A monitor is an electronic output device that is also known as a video display terminal (VDT) or a video display unit (VDU). It is used to display images, text, video, and graphics information generated by a connected computer via a computer's video card.

         (2)CPU(central processing unit) 

A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. This contrasts with external components such as main memory and I/O circuitry,^[1] and specialized processors such as graphics processing units (GPUs).

The form, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the fetching (from memory), decoding and execution of instructions by directing the coordinated operations of the ALU, registers and other components.

Most modern CPUs are implemented on integrated circuit (IC) microprocessors, with one or more CPUs on a single IC chip. Microprocessor chips with multiple CPUs are multi-core processors. The individual physical CPUs, processor cores, can also be multithreaded to create additional virtual or logical CPUs.^[2]

An IC that contains a CPU may also contain memory, peripheral interfaces, and other components of a computer; such integrated devices are variously called microcontrollers or systems on a chip (SoC).

                     USE OF CPU :-

All kinds of computing devices such as tablets, PCs, or laptops feature a brain-like unit called the central processing unit or CPU. Your computer's CPU calculates and interprets instructions while you're surfing the web, creating documents, playing games, or running software programs.

                     (3) KEYBOARD

A keyboard is one of the primary input devices used with a computer. Similar to an electric typewriter, a keyboard is composed of buttons used to create letters, numbers, and symbols, and perform additional functions.

KEYBARD

USE OF KEYBOARD :-

A keyboard is for putting information including letters, words and numbers into your computer. You press the individual buttons on the keyboard when you type. The number keys across the top of the keyboard are also found on the right of the keyboard. The letter keys are in the centre of the keyboard.

                     (4)MOUSE 

A computer mouse is a handheld hardware input device that controls a cursor in a GUI (graphical user interface) for pointing, moving and selecting text, icons, files, and folders on your computer. In addition to these functions, a mouse can also be used to drag-and-drop objects and give you access to the right-click menu.                                                                                                                For desktop computers, the mouse is placed on a flat surface (e.g., mouse pad or desk) in front of your computer. The picture is an example of a Logitech desktop computer mouse with two primary buttons and a wheel.

 ASIMPLE MOUSE

          USE OF MOUSE :-

A mouse is a small hardware input device used by hand. It controls the movement of the cursor on the computer screen and allows users to move and select folders, text, files, and icons on a computer. It is an object, which needs to put on a hard-flat surface to use.

                                (5) Printer 

In computing, a printer is a peripheral machine which makes a persistent representation of graphics or text, usually on paper.^[1] While most output is human-readable, bar code printers are an example of an expanded use for printers.^[2] Different types of printers include 3D printers, inkjet printers, laser printers, and thermal printers.

PRINTER

             USE OF PRINTER :-

 Printing images and personal documents for domestic purposes. General Use: Printing documents for general purposes. Business Use: Printing business-related documents requires high-end printers. Marketing Use: Printing marketing signs & banners, using the printers that allows various materials.

                         (6) SPEAKER

Computer speakers, or multimedia speakers, are speakers sold for use with computers, although usually capable of other audio uses, e.g. for an MP3 player. Most such speakers have an internal amplifier and consequently require a power source, which may be by a mains power supply often via an AC adapter, batteries, or a USB port. The signal input connector is often a 3.5 mm jack plug (usually color-coded lime green per the PC 99 standard); RCA connectors are sometimes used, and a USB port may supply both signal and power (requiring additional circuitry, and only suitable for use with a computer). Battery-powered wireless Bluetooth speakers require no connections at all. Most computers have speakers of low power and quality built in; when external speakers are connected they disable the built-in speakers. Altec Lansing claims to have created the computer speaker market in 1990.

               USE OF SPEAKER :-

Speakers are used to connect to a computer to generate sound, which are one of the most common output devices. Some speakers are designed to connect with any kind of sound system, while some can be hooked up only with computers.
