Computer hardware can be a mechanical, magnetic, electronic component or a physical part including the digital circuitry used to make a computer system.
The hardware is not to be changed again and again like data and software. Most of the common people don’t have any basic knowledge about hardware and only personal computer holders, electricians and hardware students have seen the hardware devices.
Mother board, power supply, storage controllers, video display controller, internal storage, sound card and networking are few essential parts of computer hardware.
Random Access Memory is like a blank piece of paper that the computer system keeps notes in. Memory is accessed faster than the hard drive. Ram works with two features as: size and Speed. Memory size is expressed in Megabytes or Gigabytes.
A hard drive is the place where computer stores all the data. All the written information Stays there, even when the computer is powered off.
‘’Computer fan’ works to decrease the temperature of the computer and it’s basically attached to the CPU. ‘Power supply’ holds transformer, voltage and a cooling fan and supplies electric power to all parts of the computer.
‘Video display controller’ produces the output for computer display. A printer produces a copy of documents while monitor is a device that displays the video signals. Networking connects the computer with internet and other computers. Thus Hardware is all about the internal parts of the computer that operates the whole functions.
