What Is A Hardware?? : 

What Is A Hardware?? Hardware is a general term for the physical artifacts of a technology. It may also mean the physical components of a computer system.

Components : 

· 1 Motherboard · 2 Power supply · 3 Secondary storage · 4 Sound card · 5 Input and output peripherals Components

Motherboard : 

The motherboard is the main component inside the case. It is a large rectangular board with integrated circuitry that connects the other parts of the computer including the CPU, the RAM, the disk drives (CD, DVD, hard disk, or any others) as well as any peripherals connected via the ports or the expansion slots. Motherboard

Component directly attach to computer : 

central processing unit (CPU):- CPU performs most of the calculations which enable a computer to function, and is sometimes referred to as the "brain" of the computer. It is usually cooled by a heat sink and fan. Chip Set:- The chip set mediates communication between the CPU and the other components of the system, including main memory. External bus controllers:- support ports for external peripherals. These ports may be controlled directly by the south bridge I/O controller or based on expansion cards attached to the motherboard through the PCI bus. RAM (random-access memory) stores resident part of the current running OS (OS core and so on) and all running processes (application parts, using CPU or input/output (I/O) channels or waiting for CPU or I/O channels). BIOS:- The BIOS includes boot firmware and power management. The Basic Input Output System tasks are handled by operating system drivers. Internal Bus:- Internal buses connect the CPU to various internal components and to expansion cards for graphics and sound. Component directly attach to computer

Power Supply : 

Inside a custom-built computer: the power supply at the bottom has its own cooling fan. A power supply unit (PSU) converts alternating current (AC) electric power to low-voltage DC power for the internal components of the computer. Some power supplies have a switch to change between 230 V and 115 V. Other models have automatic sensors that switch input voltage automatically, or are able to accept any voltage between those limits. Power supply units used in computers are nearly always switch mode power supplies (SMPS). The SMPS provides regulated direct current power at the several voltages required by the motherboard and accessories such as disk drives and cooling fans. Power Supply

Secondary Storage : 

Hardware that keeps data inside the computer for later use and remains persistent even when the computer has no power. Hard disk – It store permanent data till its Deleted by user. Solid-state drive - a device similar to hard disk, but containing no moving parts and stores data in a digital format. RAID array controller - a device to manage several internal or external hard disks and optionally some peripherals in order to achieve performance or reliability improvement in what is called a RAID array. Secondary Storage

Sound Card : 

Enables the computer to output sound to audio devices, as well as accept input from a microphone. Most modern computers have sound cards built-in to the motherboard, though it is common for a user to install a separate sound card as an upgrade. Most sound cards, either built-in or added, have surround sound capabilities. Sound Card

Input Peripherals : 

Input peripipherals includes 1.Keyboard 2.Pointing Device 3.Gaming Device 4.Web Cam 5.Microphone Input Peripherals

Input Peripherals : 

Text input devices Keyboard - a device to input text and characters by depressing buttons (referred to as keys or buttons). Pointing devices Mouse - a pointing device that detects two dimensional motion relative to its supporting surface. Optical Mouse - uses light to determine mouse motion. Trackball - a pointing device consisting of an exposed protruding ball housed in a socket that detects rotation about two axes. Touchscreen - senses the user pressing directly on the display Input Peripherals

Input Peripherals : 

Gaming devices Joystick - a control device that consists of a handheld stick that pivots around one end, to detect angles in two or three dimensions and reports its angle or direction to the device it is controlling. Game pad - a hand held game controller that relies on the digits (especially thumbs) to provide input. Game controller - a specific type of controller specialized for certain gaming purposes. Image, Video input devices Image scanner - a device that provides input by analyzing images, printed text, handwriting, or an object. Web cam - a video camera used to provide visual input that can be easily transferred over the internet. Audio input devices Microphone - an acoustic sensor that provides input by converting sound into electrical signals. Input Peripherals

Output Peripherals : 

Output peripherals includes 1.Printer 2.Speakers 3.Monitor Output Peripherals

Output Peripherals : 

Output Peripherals Printer - a device that produces a permanent human-readable text of graphic document. Speakers - typically a pair of devices (2 channels) which convert electrical signals into audio. Headphones - for a single user hearing the audio. Monitor - an electronic visual display with textual and graphical information from the computer. CRT - (Cathode Ray Tube) display LCD - (Liquid Crystal Display) as of 2010, it is the primary visual display for personal computers. LED - (light-emitting diode) display OLED - Organic Light-Emitting Diode
