What is Computer Hardware ?

what is computer hardware
The definition of Computer hardware is defined here. Computer hardware is the physical components of a computer such as CPU, Monitor, Keyboard, Graphics Card, Sound Card, Speakers, Motherboard, Storage devices, etc. Hardware refers to the physical elements of a computer. A computer's hardware is comprised of many different parts, but perhaps the most important of these is the motherboard. The motherboard is made up of even more parts that power and control the computer. Without any hardware, your computer would not exist, and software could not be used. The hardware device like Logitech webcam allows users to take videos or pictures, and transmit them over the Internet. This is more about What is computer hardware.
There are two types of Hardware attached with the computer system. The both types of hardware are External and Internet hardware.

Computer External Hardware – The hardware which is found outside your computer system are called External Hardware. These hardware are Flat Panel, Monitor, LCD, Gamepad, Joystick, Keyboard, Microphone, Mouse, Printer, Projector, Scanner, USB thumb drive and Speaker.

Computer Internal Hardware The hardware which is found inside your Computer System are called Internal Hardware. These hardware are CPU (Laptops), FAN, Modem (Laptops), Motherboard, Network Card, RAM, Sound Card, Video Card and Power Supply.
The design of hardware differs between desktop PCs and laptops due to their differences in size, the same core components will be found in both. Without hardware, there would be no way of running the essential software that makes computers so useful. Although a computer can function only when both hardware and software are working together, the speed of a system will largely rely on the hardware used.

What is Motherboard?

The motherboard is at the center of which makes a PC work. It houses the CPU and is a hub that all other hardware runs through. The motherboard acts as a brain; allocating power where it’s needed, communicating with and coordinating across all other components. Although the motherboard is just one piece of circuitry, it is home to another one of the most important pieces of hardware like processor.

What is CPU (Central Processing Unit)?

CPU (Central Processing Unit) is called as the Brain of Computer. It is responsible for processing all information from programs run by your computer. The computation speed of CPU is measured as Clock Speed or says Gigahertz (GHz).

What is RAM (Random Access Memory)?

Random Access Memory, or RAM, is hardware found in the memory slots of the motherboard. The role of RAM is to temporarily store the information created by programs and to do so in a way that makes this data immediately accessible.

What is Hard Drive?

The hard drive is a storage device responsible for storing permanent and temporary data. This data comes in many different forms, but is essentially anything saved or installed to a computer, For example, computer programs, family photos, operating system, word-processing documents, etc.

What is Power Supply Unit (PSU)?

A power supply unit (PSU) does more than after supplying your computer with power. It is the point where power enters your system from an external power source and is then allocated by the motherboard to individual component hardware. A modern computer will generally need a PSU rated between 500W – 850W to effectively power all hardware, although the size of the PSU will depend entirely on the power consumption of the system.
