The Hardware Level of the operating system controls the use of physical system resources, such as the memory manager, process manager, disk drivers, etc.

what are computers used for?

  Computers are used for a wide variety of purposes.

  Data processing is commercial and financial work. This includes such things as billing, shipping and receiving, inventory control, and similar business related functions, as well as the “electronic office”.

Scientific processing is using a computer to support science. This can be as simple as gathering and analyzing raw data and as complex as modelling natural phenomenon (weather and climate models, thermodynamics, nuclear engineering, etc.).

Multimedia includes content creation (composing music, performing music, recording music, editing film and video, special effects, animation, illustration, laying out print materials, etc.) and multimedia playback (games, DVDs, instructional materials, etc.).

Computer hardware is best described as all the physical parts of your computer, the parts you can feel and touch.Hardware is refers to the physical parts of a computer system

Parts Of Computer Hardware

Hardware:- The physical components that make up a computer are called hardware parts. Some of the components are used for input , processing, storage and others for output purposes. There are two types of computer hardware.

(1) External/outside parts of the hardware

(2) Internal/inside parts of hardware

(1)External / Outside Parts Of Hardware

The main external parts of computer are described here.

(1) Cpu     (2) keybord     (3) Moniter    (4) Mouse    (5) Printer (6) Speakers

Pictures of these parts are shown below.

1) C.p.u-Central Processing Unit 

The CPU is one of the most important parts of a computer,The Central Processing Unit (CPU),also known as CPU.The CPU is the brains of the computer where most calculations take place.Central processing unit, the heart of a real system, is the unit that controls and supervises all functions of the machine.

(2) Monitor

Monitor (or screen) is a device which is used to display the input, job processes and output of computers.t is being connected to graphic cards which prepare data for it to be able to display it as text and graphical information for users.  It provides an output from the computer so it is an output device 

(3) Keyboard

 

keyboard is the main way to enter information into your computer. A keyboard is the set of typewriter-like keys that enables you to enter data into a computer.The keyboard is used to control computer.

(4) Mouse

A computer mouse is an input device that is most often used with a personal computer.Mouse is the pointing device that controls a pointer on the screen.It allows users to navigate across the Windows desktop, performing virtual operations with the click of a button.

(5) Printer

A computer printer is a computer peripheral device that produces a hard copy (permanent human-readable text and/or graphics, usually on paper) from data stored in a computer connected to it. A printer is used to print anything that you want, like pictures or documents or data. 

(6)Speakers

    

The computer speaker is an Audio output device.Speakers are popular output devices used with computer systems. They receive audio input from the computer's sound card and produce audio output in the form of sound waves.  Speakers usually come in pairs, which allows them to produce stereo sound from two separate audio channels.
