What is hardware?
Computers consist of two parts hardware and software. Computers cannot work without any of them.
Hardware is what makes a computer work. Without hardware, a computer would not function properly.
In addition to providing basic computing power, the hardware also helps manage data storage and communication between programs.
Internal Hardware devices
The computer has many internal hardware devices like a hard drive,
HDDs were once known as Winchester drives after the manufacturer Western Digital.
Solid State Drive (SSD)
Solid state drives are a type of storage device that uses solid-state memory to store persistent data. SSDs use flash memory chips instead of electromechanical devices such as hard disks and optical discs.
Flash memory is much faster than electromechanical devices, making them ideal for storing frequently accessed files.
The motherboard is the central processing unit (CPU) of a computer. It is the heart of the computer and contains the CPU, memory chips, and various connectors.
The motherboard is often referred to as the brain of the computer.
Central Processing Unit (CPU)
External Hardware of computer
Input hardware devices
Input hardware devices are used to enter data into the computer. Users enter data through these devices.
The keyboard is the most important input hardware device. Most of the data is entered through the keyboard. There are many buttons on the keyboard for different purposes. Every button performs a different function.
A microphone is an audio input device. It is used to enter audio into the computer. The process of entering any sound into the computer is called audio input.
The camera is an input device. It stores images digitally in its memory rather than recording them on film. The picture taken with a digital camera can be transmitted to a computer system. Many digital cameras allow users to edit images.
There are many other input hardware devices are memory cards, touchpads, etc.
Output hardware devices
Output devices are used to accept data from the computer. These devices are used to display output to the users.
Monitors display images produced by video cards and are often used as television receivers. A CRT monitor uses a vacuum tube while LCD displays use liquid crystals.
Speakers are the audio output device. It is used to listen to the audio. The computer has its internal speakers but the voice quality of these speakers is not too good. So the users need to attach external speakers for better voice quality.
The printer is an output device. It is used to print character symbols documents etc. The printed copy is called the hard copy. It provides a printed copy of the document.
