The physical part of computer is call hard ware.the user can see and tuch the hard ware parts .hard ware is paly important role to run computer system.Rather, software is a set of instructions that can be store and execute by hardware.

what is hardware?

Computer hardware includes the physical components of your computer, such as the case, [1] central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speaker, and motherboard. ]

Software, by contrast, is a set of guidelines that can be store and implement on hardware. Hardware is call “soft” because it is ”   very hard” or hard to adapt for changes, while hard ware is “soft” because it is easy to change.

Software usually directs the hardware to execute any command or instruction. The combination of hardware and software makes a usable computer system, but other systems are only available in hardware.


The keyboard  is  main  part of the computer. This is a board with integrate circuits that connect to other parts of your computer, such as the CPU, RAM, disk drives (CDs, DVDs, hard disks, etc.), and parts connecte through expansion ports and slots. .. Computer integrate circuit (IC) chips typically contain billions of small metal oxide semiconductor field effect transmitters (MOSFETs). []]

The parts that are directly or attache to the motherboard are:

The CPU (Central Processing Unit) performs many calculations that allow a computer to function and is known as the brain of a computer. It receives a program instruction from program access memory (RAM), interprets it, processes it, and sends the result to the relevant.

component to implement the instruction. The CPU is a microprocessor, built on a metal oxide microphone semiconductor (MOS) integrate circuit (IC) chip.

It is usually coole by a heat sink and fan, or a water cooling system.The CPU manages the clock speed base on the instruction execution speed and is measure in GHz.

Specific values ​​are 1 GHz to 5 GHz. Most modern computers have the option of monitoring the CPU, which consumes large amounts of heat products and improves performance and needs to be improve.

The chipset, including the northbridge, creates a connection between the CPU and the rest of the system, including main memory. Similarly, the South Bridge, which is connecte to the North Bridge and supports consumers and buses.

And finally, a Super I / O chip connecte via a southbridge that supports slow, legacy components such as serial ports, hardware monitoring, and fan control.
Land access memory (RAM). For example, opening a web browser on your computer consumes memory. It is saved in RAM to close the web browser.

This is typically a form of dynamic RAM (DRAM), such as synchronous DRAM (SDRAM), where the MOS memory chip stores the data in a memory cell that contains a MOSFET and a MOS capacitor. RAM is typically provided in 2GB, 4GB, and 8GB sized dual inline memory modules (DIMMs), but can be very large.

Read-only memory (ROM). Stores the BIOS while the computer is running or when it starts running. This is a process called bootstrap, or “boot” or “boot”. ROM is typically a discrete BIOS memory chip that stores data in front-door MOSFET memory cells.

The BIOS (Initial Logon System) contains boot firmware and power management firmware. New motherboards use Unified Extensible Firmware Interface (UEFI) instead of BIOS.

what is computer hardware and software with examples:

A bus that connects the CPU to various internal components and extends the graphics and sound card.
CMOS (Complete MOS) battery.

Powers the date and time CMOS memory on the BIOS chip. This battery is usually a watch battery.
A video card that handles computer graphics (also known as a graphics card). Very powerful graphics cards are ideal for handling difficult tasks such as playing high-speed video games and running computer graphics software.

The video card has a graphics processing unit (GPU) and video memory (usually SDRAM type), both built on a MOS integrated circuit chip (MOS IC).
Power MOSFETs create voltage regulator inputs (VRMs) that control the voltage between other hardware components. [8]

Storage devices are computer hardware and digital media use to store, transfer, and extract files and data objects. Data may be store and store temporarily and permanently, and may be lock on or off a computer, server, or similar computer device. Data storage is a key feature of your computer.

Fixed media:

Your computer stores data using a variety of media. Hard disk drives (HDDs) are virtually found on all older computers due to their large capacity and low cost, but state-of-the-art drives (SSDs) are now more expensive than hard drives in terms of price per unit. . It’s also expensive, but fast and very energetic.

Gigabytes [10] are common on personal computers produce since 2007. [11] SSDs use flash memory to store data on MOS memory chips that contain the Flogite Gate MOSFET memory cells.

Removable storage:

You can use an external flash memory device (such as a memory card or USB flash drive) or an optical disk (such as CD-ROM, DVD-ROM, BD-ROM) to transfer data between computers.

Their usefulness depends on whether they are readable by other systems. Most machines have optical disk drives (ODDs), and virtually all have at least one universal serial bus (USB) port.

Log in and out:

Access and exit devices are usually locate outside the main chassis of the computer. The following are standard or very common in most computer systems.

Login device
Hidden devices allow users to enter information into the system and control the system’s behavior. Most personal computers have a mouse and keyboard, but notebook systems typically use a trackpad instead of a mouse. Other input tools include webcams, microphones, joysticks, and a photo scanner.

Exit device:

The product device is designe with human emotions in mind. For example, an observer displays readable text and a speaker produces audible sound. [12] These tools include Braille printers and embossing machines.

Central computer

Mainframe computers are very large computers that usually fill a room and can cost hund or even thousands of times more than a personal computer. They are designe to perform a large number of calculations for governments and large corporations.

In the 1960s and 1970s, many departments began using inexpensive dedicate systems for specific purposes, such as process control and laboratory automation. Minecraft computers or literal Mine computers were create in the mid-1960s [13] [14] and IBM and its closest rivals sold them at much lower prices than the mainframe [15] and made the computers smaller.

This is a class of small computers.


Main article: Supercomputers
Supercomputers are superficially similar to mainframes, but instead focus on more demanding computer tasks. As of June 2020, the fastest supercomputer on the TOP500 supercomputer list is Japan’s Tomato,

with a Linpen benchmark score of 415 PFLOPS, nearly 294 PFLOPS higher than the second fastest supercomputer in the United States.0

The term supercomputer does not refer to any particular technology. Rather, it shows a quick calculation available at any time. In mid-mid-2011, the fastest computers had speeds of more than pet flopping or trillions (10 ^ 15 or 1000 trillion) per second of floating-low performance per second.

Supercomputers are fast but very expensive, and are commonly use by large organizations to perform computing tasks, including large data sets. Supercomputers often
