Going end the parts of a computer and also their attributes will aid you understand all the crucial components that comprise a computer.

You are watching: What are the physical components of a computer

It’s a great place to begin if you want to begin learning around computers. Not just is it a great entry point, however it’s also something an excellent to recognize for curiosity’s sake.

Knowing what the component is, is good, however we will describe each part’s function, which will give you a firmer understanding of them.

Parts the a computer with their functions

Here is a finish list of all the common computer hardware components and also common peripherals provided with them.

1. The computer case


A graphic card procedures the data from the motherboard and sends the appropriate information to the monitor because that it to it is in displayed.

It deserve to do so using an HDMI, DisplayPort, DVI, or VGA connector.

A graphics map can likewise be described as a video card or a screen card.

It take away the load of every the video processing native the key CPU. This provides a computer system a large boost in performance.

Because the the big processing requirements for a gaming graphic card, fans are practically a given.

A graphics map plugs into a PCI express (Peripheral component Interconnect Express) slot top top the motherboard. It is a serial growth bus slot capable of a high quantity of bandwidth in 2 directions.

A graphic card has a GPU (Graphics processing Unit) which is the key component that needs cooling.

A GPU is slower 보다 a CPU, however it is draft to resolve mathematical operations required for video clip rendering.

The quantity of memory on the card varies relying on the manufacturer’s design.

Graphics cards usage GDDR (Graphics dual Data Rate) SDRAM, i m sorry is particularly designed to optimize graphic performance.

GDDR is constructed to take care of a higher bandwidth contrasted to level DDR ram.

6. Sound Card

Most the the time, the sound chip developed into the motherboard is offered for audio output.

But, if you room a sound enthusiast or prefer greater detailed audio while play a game, you can be skinny to usage a sound card.

Sound cards plug into a computer system in lot of ways. It deserve to be v USB, PCI slot, or PCI to express x 1 slot.

A sound handling chip ~ above the map does all of the audio processing and is usually not a very powerful processor.

A sound card deserve to offer a wide selection of connectivity with various audio equipment.

A couple of examples could be optical audio, 1/4 customs jack, or RCA connectors.

7. Hard Drive

A difficult drive is found in most computers. It’s commonly a mechanical drive the stores every the data.

Apart native storing data, that can likewise be supplied as a boots drive to run the operating mechanism from it.

An operating device is a software routine that makes a computer useable prefer Microsoft Windows, because that example. The biggest vulnerability the a mechanical journey is that physically breakable nature.

One bang the wrong means can ruin a entirety drive. A mechanical difficult drive includes one or much more platters the spin anywhere in between 5200 to 10000 RPM (revolutions per minute).

The read and write heads room spaced only around 0.002 (51 micro M) inches far from the platter.

This provides you an idea about the physics limitations about its fragile nature.

Small areas on the platter can be arranged to stand for a 1 or a 0. It have the right to be readjusted using the journey head to transform the material to represent the correct worth magnetically.

8. SSD: heavy State Drive

An SSD is likewise a type of difficult drive, however it doesn’t have any kind of moving parts. It consists of a financial institution of flash memory that have the right to hold a reasonable amount of data.

While SSD’s are boosting in dimension all the time, lock aren’t cost-effective because that storing huge amounts that data.

A mechanical drive has a cheaper gigabyte come dollar ratio.

However, the SSD is a high-performance drive. It’s fast and also cannot be as conveniently damaged by dropping the or acquisition a few knocks.

That’s why I constantly recommend SSD’s because that portable-type computers where possible. You have the right to read an ext about whether or no SSD’s room worth that in our various other article.

9. PSU: strength Supply Unit

A strength supply mounts inside the computer case. This switch the AC mains it is provided from the wall surface socket and supplies the exactly DC voltages to every the components inside the computer.

A computer power supply gives the complying with voltages:

+3.3v: This voltage is supplied to the motherboard.+5V: This voltage is offered to the motherboard and also other interior components.+12V: This voltage is provided to the motherboard and other internal components.-12V: This voltage is provided to the motherboard.

You get different wattage ratings for strength supplies. The greater the wattage, the greater the electrical current that have the right to be made obtainable to components that require it.

The greater you walk in Watts, the much more the power supply will certainly be most likely to cost.

A strength supply also comes with its very own cooling fan. This helps every the internal contents to stay cool as soon as the power supply is subjected to bigger loads.

If girlfriend would favor to know an ext about a strength supply and also its lifespan, I have actually written an short article discussing it more in-depth.

10. Monitor

A monitor is what you use to visualize the graphic data sent out from the computer’s graphics card.

There room various varieties of monitors top top the market. The most generally used is a LED-backlit LCD monitor.

There are likewise a range of various sizes with different element ratios. The facet ratio is merely the ratio between height and width.

For example, a 16:9 element ratio screen will have actually 16 parts large to 9 parts in height.

There are likewise curved monitors, however they are an ext expensive.

Monitors additionally have a fast an answer time to keep up v the high demands compelled to eliminate delays with user input for gaming.

11. Keyboard

A keyboard is just one of the ways to connect with a computer. Typing a vital from the keyboard sends a small section of data to tell the computer which crucial was pressed.

The computer can usage this info in countless ways. An example could it is in a command or a personality that deserve to be offered in a document.

There space two main different species of keyboards. Mechanical and membrane types.

12. Mouse

A mouse permits the user to relocate a pointer presented on the monitor and experience a an ext intuitive communication with the computer.

These days mouse have much more buttons than the common three.

However, the three main buttons allow the user to select, grab, role and access extra menus and also options.

A computer mouse deserve to be wired or wireless. The latter obviously requires batteries.

Optical mice of today permit for really accurate precision and smooth movement.

Common external peripherals

Here are some usual peripherals that get linked to a computer and also extends that usefulness.


A printer have the right to take photo sent by a computer and also deliver it onto a paper of paper.

It go this by using the data indigenous the computer, and by either making use of toner or ink, it deposits among these in a controlled and accurate path to kind the image.


A scanner deserve to take something on document and scan it to develop a replicated digital image.

This is also very handy for conserving physical photos the you want to preserve.

Once the photo is stored digitally, the won’t degeneration as a physical picture does end time.

Computer Speakers

Computer speaker can attach up to the sound card at the behind of the computer.

Another means they deserve to be linked is by a monitor that already has integrated speakers.

Generally, the sound high quality is poor from a monitor’s speakers. That’s why most people buy a collection of computer speakers to have on their computer system desk.

You can even connect up a 7.1 surround speaker system to details sound cards.

This can add a nicer suffer to gaming, playing music, or watching a film.


That consist of the straightforward components that a computer. All of these components play a critical function for a computer system to work.

Once you recognize these contents to a an easy level, it more than likely won’t be lengthy until you fix or construct computers yourself.
