Summary: Difference Between Software and Hardware is that Software, also called a program, is a series of related instructions, organized for a common purpose, that tells the computer what task(s) to perform and how to perform them. While a computer contains many electric, electronic, and mechanical components known as hardware. These components include input devices, output devices, a system unit, storage devices, and communications devices.

Software

Software, also called a program, is a series of related instructions, organized for a common purpose, that tells the computer what task(s) to perform and how to perform them. You interact with a program through its user interface. Software today often has a graphical user interface. With a graphical user interface (GUI pronounced gooey), you interact with the software using text, graphics, and visual images such as icons. An icon is a miniature image that represents a program, an instruction, or some other object. You can use the mouse to select icons that perform operations such as starting a program. The two categories of software are system software and application software.

Hardware

A computer contains many electric, electronic, and mechanical components known as hardware. These components include input devices, output devices, a system unit, storage devices, and communications devices. Just like an input device is any hardware component that allows you to enter data and instructions into a computer. Common computer hardware components include the keyboard, mouse, microphone, scanner, Web cam, printer, monitor, speakers, system unit, hard disk drive, external hard disk, optical disc drive(s), USB flash drive, card reader/writer, memory cards, and modem. A communications device is also a hardware component that enables a computer to send (transmit) and receive data, instructions, and information to and from one or more computers or mobile devices.

What is a Computer?

A computer is an electronic device, operation under the control of instructions stored in its own memory. In Information Processing Cycle, there have Collects Data (Input), Processing, Produces Information (Output).

A computer contains many electric, electronic and mechanical components known as hardware.

• Input Device – Allows you enter data and instructions into a computer.
• Output Device – Hardware component that conveys information to one or more people.
• System unit – Case that contains the electronic components of the computer that are used to process data.
• Storage Device – Holds data, instructions, and information for future use.
• Communication Device – Enables a computer to send and receive data, instructions, and information to and from one or more computers or mobile devices.

Advantages and Disadvantages of Using Computers

Advantages:

• Speed
• Reliability
• Consistency
• Storage
• Communication

Disadvantages

• Health Risks
• Violation of Privacy
• Public Safety
• Impact on Labor Force
• Impact on Environment

Green Computing involves reducing the electricity consumed and environmental waste generated when using a computer

We can practice recycling, regulating, manufacturing process, extending the file of computers, immediately donating or properly disposing of replaced computers.

Before this computer use CRT monitor. CRT is a Cathode Ray Tube that that produces radiation that affect to the user health. But nowadays most computers has change to LCD monitors (Liquid Crystal Display) that more safe and convenience.
