Output hardware
The purpose of output hardware is to provide the user with the means to view information produced by the computer system. Information is output can be held in your hand, such as paper with text (word or numbers) or graphics printed on it. Softcopy output is displayed on a monitor.
Monitor is a component with a display screen for viewing computer data, television programs, etc. Printer is a computer output device that produces a paper copy of data or graphics.
Modem is an example of communication hardware - an electronic device that makes possible the transmission of data to or from computer via telephone or other communication lines.
Hardware comes in many configurations, depending on what the computer system is designed to do. Hardware can fill several floors of a large office building or can fit on your lap.

2. The purpose of the input hardware is to collect data and convert it into a form suitable for computer processing.
3. Scanner is used to input graphics only.
4. The purpose of processing hardware is to retrieve, interpret and direct the execution of software instructions provided to the computer.
5. CPU reads and interprets software and prints the results on paper.
6. User is unable to change the contents of ROM.
7. 5.25” floppy disks are used more than 3.5” disks.
8. Printer is a processing hardware because its purpose is to show the information produced by the system.
9. Modem is an electronic device that makes possible the transmission of data from one computer to another via telephone or other communication lines.
10. The purpose of storage hardware is to store computer instructions and data in a form that is relatively permanent and retrieve them when needed for processing.

B Parts of computer
A computer is an electronic machine that accepts, processes, stores and outputs information. a typical computer consists of two parts: hardware and software. Hardware is any electronic or mechanical part of the computer system that you can see or touch.
Software is a set of instructions, called a program, which tells a computer what to do. There are three basic hardware sections.
1. The CPU is the heart of the computer, a microprocessor chip which processes
data and coordinates the activities of all the other units.
2. The main memory holds the instructions and data which are being processed by
the CPU. It has two main sections: RAM (random access memory) and ROM
(read only memory).
3. Peripherals are the physical units attached to the computer. They include:
Input devices, which let us enter data and commands (e.g. the keyboard and the
mouse).
Output devices, which let us extract the results (e.g. the monitor and the printer).
Storage devices, which are used to store information permanently (e.g. hard disks and DVD-RW drives). Disk drives are used to read and write data on disks. At the back of a computer there are ports into which we can plug external devices (e.g. a scanner, a modem, etc.). They allow communication between the computer and the devices.
C Functions of a PC: input, processing, output, storage
Input We enter data with a keyboard, a webcam, etc.
Processing The data is manipulated according to program instructions.
Output We can see the result on the screen or in printed form.
Storage We keep data and programs in memory systems where they are
available for processing.
