Computer Hardware and Their Function

Your personal computer is a simple computer that does not have too many functionalities, for it is made for home users. To understand how your computer works, you should first learn what is your computer made up of.
Your PC is a combination of software and hardware systems. To allow the software to run efficiently is a computer hardware function. Computer Hardware is a vehicle that is used by the software to produce results and deliver them to us.

All visible components of your computer system that you can touch with your fingers is hardware. It is a set of many devices and components. They are interconnected with each other to produce desired result.

Computer Hardware Components

There are several of them, but the most important of them is CPU (Central Processing Unit). It calculates, takes decisions, performs arithmetic and logical functions. It is fitted on a motherboard, which also holds RAM ( Random Access Memory) ROM (Read-Only Memory), chips, etc.

Input and output devices are used for feeding and getting back the desired information in the desired format. A power supply that converts AC power source into DC source is required to run the functions.

Computer Hardware Functions

It provides a platform for a software to run. Without hardware, there is nothing. Single hardware component is also good for nothing; it has to be basic set that can give us some kind of output with combined efforts.

Input devices are used to feed the instructions into the computer. Keyboard allows us to insert text. Pointing devices like mouse can help us to point and select graphical images and icons on the screen. Tracking devices like tracking balls, audio devices like microphone, and image scanning device like scanner serve different purposes.

Output devices like speaker and printer are familiar to us. And do not forget the most essential and important of them all, the monitor, which generates the video output.

Devices like CPU, RAM, memory, etc., are the most important and essential to start the system. Without them no other device can be used.

Computer Hardware

Computer hardware is not a device, but a set of multiple devices and machinery. This is the visible part of your computer system.

Input devices like keyboard and mouse are used to enter the text, command, or any other instructions. Output devices like printers are used to print the text and images. Monitor and speaker are some of the essential output devices.

CPU (Central Processing Unit) is both the heart and the brain of your computer. It does all the work through the programmed chips. It has its own speed.

Hard disk drives and external disk drives are external storage devices used to store data externally. Pen drives, CD (Compact Disk), DVD (Digital Video Disk), and smart cards are also used to store data.

Computer RAM (Random Access Memory) is an internal memory of a computer that decides the overall speed of a computer. Two to four gigahertz memory is sufficient for most of the software applications to run safely on your computer.

Computer Networking

A computer network is nothing but a connection of different computers through some channels. This connection is very important for many computers to share common data and operate synchronously. This saves a lot of space, time, and money. Special care has to be taken for computer hardware network security.

LAN (Local Area Network) is a network limited by space and can be accessed in certain area only, whereas WAN (Wide Area Network) is a network that connects computers set up in longer distances.

Internet is a system of interconnected networks all over the world. It has its own standards known as protocols. For example, TCP (Transmission Control Protocol) and IP (Internet Protocol)

A network can be wired or wireless. Wired networks make use of different types of wires such as twisted, co-axial, and optical fiber.

Difference between Computer Hardware and Software

Computer hardware is best described as a device that's physically connected to the computer or anything that can be touched physically. A monitor, CD-ROM, video card, and a printer are all examples of computer hardware. On the other hand, computer software refers to the code that eventually provides instructions for hardware components to follow. Operating systems, word processors, etc. are examples of computer software.

Hardware is usually multipurpose which means that several different tasks can be carried out on the same piece of hardware. For instance, a computer monitor can not only display images, but also text, videos, and widgets. On the other hand, most software is designed to perform only one task or few similar tasks.

The failure of the hardware is random and it does have increasing failure at the last stage. Software failure is systematic and it doesn't have an increasing failure rate. Hardware is mostly reliable throughout the life, whereas software needs constant testing after upgrades. The hardware starts functioning once the software is loaded and the software is installed on the hardware to deliver its set of instructions.

Both computer software and hardware are frequently in development. In hardware development, latest technology is used for creating faster and more compact computer components. To keep up with hardware advancements, software developers constantly strive to work hard by providing more inclusive, better looking, and smooth running software.

Hardware and software are interdependent on each other, which mean that hardware cannot function till software is installed in it to set the programs in action.
