The hardware/components of computer
today i will post you the difference between all computer components / hardware and it's functions
if you know all the components and its function, it's ok to read it, and if you know the components but you don't know the functions this might usefull :)
okay, first :
Case
The case is the part of your computer that holds all the other parts. Some common types of computer cases are: full-tower, mid-tower, mini-tower, and laptop. If you have a desktop computer, you are likely using a mid-tower; if you are using a notebook computer, you have a laptop case.
Motherboard
The motherboard is the part of your computer that wires all of the other parts together. Every component of your computer, from the DVD burner to the CPU, will connect directly into the motherboard. Motherboard specs are typically designed around which processor (CPU) the computer uses. For example, if your computer uses an Intel processor, you will need an Intel compatible motherboard.
Processor
The processor, or CPU, of a computer is basically the brains of the computer. The processor is responsible for interpreting every code it receives from the other computer components, and making it usable to your operating system. Some common types of processors are Intel Core 2 Duo and AMD Phenom. A processor's speed will often determine the overall speed of your computer.
Hard Drive
The hard drive part of your computer is very simple. Essentially, it is the part of the computer that stores all your information. If you upload a picture to your computer, it is stored on the hard drive. Hard drive capacity is measure in gigabytes, or GB. There are typically two ways that hard drives can connect to the motherboard: SATA and IDE.
Video Cards (Graphic Cards)
A graphic card is the component of your computer that interprets video signal. These cards are necessary so that you can connect a monitor to your computer. There are many types of graphic cards available: anything from high-end gaming cards to TV tuner cards. Some popular graphic card manufacturers are NVIDIA, ATI, and EVGA.
RAM (Memory)
You may have heard of people upgrading the RAM in their computers. RAM is the part of your computer that is used as instant memory. RAM is always in use. For example, if you run many programs at once, you may want to upgrade your RAM because your computer is using more memory. RAM comes in many different configurations, such as DDR2 and DDR3. The type of motherboard you have will determine your RAM.
Optical Drive
An optical drive is many times the drive you would use to burn CDs, DVDs, Blu-Ray discs and more. Optical drives can be either slot loading, or tray loading and come in many different configurations. Optical drives connect directly to the motherboard of the computer.
Power supply (PSU)
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.
Monitor
This device which operates like a TV set lets the user see how the computer is responding to their commands. A monitor or display (also called screen or visual display unit) is an electronic visual display for computers. The monitor comprises the display device, circuitry, and an enclosure. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors use a cathode ray tube about as deep as the screen size.
Keyboard
In computing, a keyboard is a typewriter-style keyboard, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches. Following the decline of punch cards and paper tape, interaction via teleprinter-style keyboards became the main input device for computers.
Despite the development of alternative input devices, such as the mouse, touchscreen, pen devices, character recognition and voice recognition, the keyboard remains the most commonly used and most versatile device used for direct (human) input into computers.
Mouse
In computing, a mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons. It sometimes features other elements, such as "wheels and led sensor", which allow the user to perform various system-dependent operations, or extra buttons or features that can add more control or dimensional input. The mouse's motion typically translates into the motion of a cursor on a display, which allows for fine control of a graphical user interface.but always remember, it's not a real mouse -.-
that's all i know about computer components, hope this is usefull to you :)
thanks for reading :)
