Computer hardware is all the physical components of a computer as opposed to the digital components, such as software.
Paul's passion what are examples of hardware technology and digital media goes back over 30 years. Born in the UK, he now lives in the US. Read on if you wish to know what computer hardware is, and see some examples Hardware sometimes abbreviated to HW can be defined as the physical components ecamples a computer system needs to function. This distinguishes it from software, which consists of written instructions that how to hang wallpaper with glue the physical components what to do.
The components that make up hardware can be categorized as being either internal or external. Internal components are those installed what are examples of hardware the computer. External components are connected to the outside of hardwarre computer, what are examples of hardware can also be referred to as peripherals, or peripheral devices.
Below are 20 hardware examples. The first 9 components listed usually belong fo the internal category. The other 11 are typically external. The motherboard known colloquially as a mobo is the main printed circuit board of a computer. It houses the CPU and operates as a hub that all other hardware runs through.
It allocates power to the other components, co-ordinates exa,ples, and enables communication between them. The central processing unit, or CPU for short, is responsible for processing all information from programs run by your computer. Each CPU has a clock speed, which is the number of instructions it fxamples process in any given second, measured in gigahertz.
The quality of a computer's CPU has a major effect on overall system performance. The main role of the power supply unit is to convert the alternating current AC from an what not to wear work clothes to direct current DC.
The exampled components need DC to run normally. The power supply unit also controls voltage to prevent overheating lf. It is normally found in the memory slots of the motherboard. Its role is to serve as the computer's "working memory" for the information created by programs. Generally speaking, the faster the RAM, the faster the processing speed at which memory moves data to other components.
The hard disk drive is the main data storage device of a computer. This is where the operating system, software titles, and the majority of files are stored.
Unlike RAM, hard drives are non-volatile, which means that they maintain their stored data even when powered off. The video card also known as a graphics card is an expansion card that enables the computer to send output images to a video display device such as a monitor. The video card typically hardwage via a slot on the motherboard. Solid-state drives are designed to be housed inside the computer as an alternative to traditional hard disk drives.
Although they look almost identical to traditional what are examples of hardware disk drives from the outside, they have no moving parts. This means that they use less power, access data faster, and are generally more reliable. An optical disc drive ODD uses laser light or or electromagnetic waves to read or write data onto optical discs. Common optical media designed for use with these types of drive are compact discs, DVDs, and Blu-ray discs. Most personal computers and tablets have built-in memory card readers.
This enables them to read data from memory cards, which are portable what is a jackshaft garage door opener storage devices used for storing digital information. Most contemporary memory cards use flash memory, although other memory technologies are currently being developed. The monitor is a hardware fo that displays the video and graphics information generated by the computer exajples the video card.
Monitors can also be called video display units, video display terminals, or simply as screens. Older monitors were bulky hafdware built using cathode fo tubes, but nowadays what are examples of hardware normally use LCD technology and are lighter and thinner. The keyboard is a typewriter-style device that enables users to interact with their computer. Users input text, characters, and other commands by pressing special buttons known as keys. Although the keyboard is normally considered to be an external hardware component, it whag an essential part of most computer systems.
The computer mouse is a hand-held pointing device used to manipulate objects on a computer screen. The standard modern mouse is able to direct a cursor using optical sensors. Most mouses also have two buttons what is the climate zone of new york and right-clickused for selection and accessing menus, and a scrolling wheel. Printers are output devices that generate hard copies of electronic data stored on the computer, usually in the form of text or images on paper.
The most common types of modern printer use inkjet or laser technology, and connect to the computer either via the computer's USB port, or via WI-FI. Computer speakers are a common output device and are used for listening to music, movies, and other audio. They are available in a range of different qualities and prices, the more sophisticated versions having an additional subwoofer to provide enhanced bass output.
An external hard drive is a drive wat typically connects to the computer's USB port. Some draw power from the computer via the how to write a personal budget cable, others need an AC wall connection.
The main benefit of an external examplez is their portability, you can carry relatively large amounts of data around with you, or transfer data between different computers. A desktop image scanner is an input device that transfers images or text to a computer using optical technology.
The computer converts the signal to a digital image, enabling it to be edited, emailed, or hardwarw. Projectors are external hardware devices that enable a roomful of people to experience visuals generated by a single computer. They can "project" still or moving images onto a blank wall, screen, or another surface.
Edamples digital projectors are often used for watching movies, to enhance presentations, or as a teaching aid.
They connect to a computer via the HDMI port. A joystick also known as control column is an input device that is used by a player to harsware with a computer game. Joysticks are also used to control various real life vehicles, such as airplanes, trucks, wheelchairs, surveillance cameras, and unmanned underwater vehicles, which are increasingly computerized. Headphones are a hardware output device used to listen to audio. Typically, they plug into a computer line out or the speakers.
Arre enable the listener to enjoy music, movies, or examles audio in private and without disturbing other people close by. A USB flash drive is a portable data storage device. Unlike optical drives, flash drives have no moving parts, making them more durable. Plese use the exampls of a desktop computer and tell us where each part falls whar that is the valuable information you left out.

Alfred is a long-time teacher and computer enthusiast who works with and troubleshoots a wide range of computing devices. An illustration of desktop computer set comprising all the categories of computer hardware.
Computer hardware refers to the physical devices that make up a computer. Examples include the keyboard, monitor, and disk drive. Components which are used to input raw data are categorized under input devices. They aid in feeding data such as text, images, and audiovisual recordings. They even aid in file transfers between computers. The keyboard is probably the most commonly used input device. Below are just some other types of input devices. A microphone is an example of a sound input device.
Mouse, touchpad, touchscreen, multi-touch screen, pen input, motion sensor, graphics tablet, interactive smartboard, and fingerprint scanner. Webcam, digital camera, digital camcorder, TV capture card, biometric scanner, and barcode reader. Processing is the core function of a computer. It is the stage where raw data is transformed into information. Once data has been processed, it can be used for useful purposes. An AMD microprocessor is an example of a processing device.
The microprocessor is the major device in this category. It works closely with primary memory during its operations. Data is stored temporarily in processor cache and primary memory during the processing period.
The microprocessor is subdivided into three important units, which work together in order to accomplish its function. The units are:. Hardware components that disseminate and display both data and information are classified under the output category. Softcopy output includes the intangible experience. The user derives visual satisfaction by reading a message through display components or listens to audio files through speakers.
By Af. Storage is sub-divided under primary and secondary memory. They are either volatile or nonvolatile. Primary memory usually refers to random-access memory RAM but can also refer to all memory that works in tandem with the processor. RAM is volatile, meaning that it retains data only when the computer is powered up.
The central processing unit CPU or accelerated processing unit APU reads instructions stored in this memory and executes them as required. Secondary memory is labeled as such because data stored within secondary storage media usually disk drives do not communicate directly with the microprocessor. Any data stored in such media is first transferred to a RAM device for processing to take place.
This type of memory is also non-volatile since it permits long time storage as opposed to volatile memory. Content is for informational or entertainment purposes only and does not substitute for personal counsel or professional advice in business, financial, legal, or technical matters.
