Computer hardware and firmware definations

Computer : computer is defined as electronic device designed to it and perform prescribed mathematical and logical operations speed to produce the results.
Hardware : Hardware is defined as the set of Physical parts of a computer and related devices. Internal hardware devices include motherboards, hard drives, and RAM. External hardware devices include monitors, keyboards, mice, printers, and scanners.

Firmware : Firmware is a software program or set of instructions programmed on a hardware device. It provides the necessary instructions for how the device communicates with other computer hardware and to perform functions like basic input/output tasks. Firmware is typically  stored in the flash ROM(read only memory) of a hardware device. It can be erased and rewritten.

Computers play a major role in providing services to the officers, houses, shops organization and even to individuals in or one or the other form. This article is introduce the computers and their components, their generation of computers, various input and output devices and clarification of computers


Computer, Hardware, Software, Firmware, High Level Language before actually entering into the actual contents of the Computer Fundamentals let us see some useful definition.

Also read : input and output devices

The internal hardware parts of a computer are often referred to as components. while internal hardware devices are usually called peripherals.

Software : software is defined the set of program and application  that run on computers.

and rewritten requirements which is a list of minimum hardware required for the software to run.
Two types of software exists: System software and Application software.

The system software is used to make the hardware of the computer to function. these include Operating Systems, Compilers, Loaders and Linkers.

The application software is user defined set of programs to do a particular job. These include Banking System, Railway reservation system, Payroll system, Electricity billing system etc.

Note : Because software runs on computer hardware, software programs often have system requirements which is list of minimum hardware required for the software to run.

You can think of firmware simply as "software for hardware." Strictly hardware devices such as optical drives, a network card, a router, or a scanner all have it software that is programmed into special memory contain in the hardware itself to make it is communicate with other devices when needed.

 You can usually find firmware updates by going to the "Support" or "Downloads" area of a manufacturer&&apposes website to update your firmware.

To understand what is firmware, let us take a situation, my friend bought a 50-pack of empty DVD discs and tried to burn a movie to a few of them but it did not work.

He contacted the DVD drive manufacturer and they suggested that he has to update the firmware on the DVD drive. The updated firmware had a new set of computer code for his drive instructing it how to write to the particular brand of DVD disc that he was using!

I hope u my dear friends we are all understand the basics of computer, hardware, and firmware. Follow me thanks.
