What is a desktop computer?

A desktop computer is a personal computing device designed to fit on top of a typical office desk.

It houses the physical hardware that makes a computer run and connects to input devices such as the monitor, keyboard and mouse users interact with. Desktop computers are commonly used in the enterprise, as well as in consumer use cases such as gaming. In the enterprise, they are important because they are the main means for many users to do their jobs.

Core features and components

A desktop computer includes the processor, which can be a microtower or minitower designed to fit under the desk or a unit that goes on top of the desk. It also includes a motherboard, the main circuit board for the computer. Desktop computer motherboards are generally standardized on Advanced Technology eXtended (ATX), microATX or Balanced Technology eXtended form factors. The desktop computer also houses disk storage.

Almost all desktop computers include a built-in modem and multi-gigabyte magnetic storage drive. They also feature standard extension slots such as Peripheral Component Interconnect Express (PCIe). They require an uninterruptible power supply (UPS), which means they must be plugged in at all times to function.

It is common for desktop computer users to pair the device with a printer. It is possible to interconnect desktop computers across a local area network (LAN) so users can share resources across devices and connect to peripherals such as printers.

A gaming computer, also known as a gaming PC, is a specialized personal computer designed for playing video games. Gaming PCs typically differ from mainstream personal computers by using high-performance video cards and high core-count central processing units with raw performance. Gaming PCs are also used for other demanding tasks such as video editing. Many gamers and computer enthusiasts choose to overclock their CPU(s) and GPU(s) in order to gain extra performance. The added power draw needed to overclock either processing unit often requires additional cooling, using upgraded air cooling or water cooling. 

Gaming computers take this to another level, like this Alienware Area-51M R2 Gaming Laptop, which features the latest Intel I9 with 10 core processors, a dedicated 8 GB graphics card, 16 GB of RAM, and 512 GB of internal storage. Gaming laptops generally do not possess touch screens since they require a large portion of energy to run, which in turn can affect the speed and frame-rate of game-play.[6]

As the size of the monitors decreased and the computer market consolidated into IBM-compatible and Apple-compatible product lines, computer companies started to integrate the computer case into the monitor to create all-in-one designs. These first all-in-one computer systems were still large and cost more than a standard desktop setup.

The most successful of the all-in-one personal computers was the Apple iMac. The original design used the cathode-ray monitor with the computer boards and components integrated below the tube.

With the advent of LCD monitors for displays and mobile parts getting smaller and more powerful, the size of the all-in-one computer system has decreased dramatically. Now, the computer components can be easily integrated behind the LCD panel or into the base of the display.

An uninterruptible power supply (UPS) is a device that allows a computer to keep running for at least a short time when incoming power is interrupted. As long as utility power is flowing, it also replenishes and maintains the energy storage.

  The Online UPS is a type of UPS that supplies power to the AC load through the Rectifier and Inverter Combo in normal operation and uses an inverter to supply AC power during a power failure. Therefore, the output power supply always stays ON and there is no need for switching. 

Batteries, on the other hand, are direct current (DC) devices, so all battery-type UPSes must convert -- or rectify -- the incoming AC power to DC to charge the batteries. The UPS must also still deliver AC to the ITE, so DC power must be converted back to AC through a device known as an inverter.

VDU stands for Visual Display Unit. It is a device that displays text and graphics on a screen. In a computer, the VDU is also known as a monitor. It is used to display the output of the computer's processing unit, allowing the user to interact with the computer and see the results of their actions.

Types of Visual Display Units

Two main technologies, liquid crystals and organic light-emitting diodes, currently dominate the market for visual displays. An older technology, the cathode ray tube, has all but vanished from the scene, and plasma monitors also see use in some applications. 

Liquid Crystal Displays

Liquid crystals are liquid materials that have some of the optical properties of crystals. A display made of liquid crystals acts like an array of tiny shutters that transmit or block light. A bright light source called a backlight, situated behind the LCD screen, shines through the LCD, creating thousands of tiny dots of red, blue and green that form a color image. Because the backlight is sealed inside the display, you normally never see it directly, only its light filtered through the LCD panel.

LCD with Fluorescent Backlight

Some LCD displays use a fluorescent lamp as the white backlight. The lamps are thin, lightweight, inexpensive and produce a bright white light. On the downside, fluorescents contain small amounts of mercury vapor. Although the mercury does not pose a serious problem in household and office settings, the environmental consequences of heavy metals from monitor e-waste are significant.

LCD with LED Backlight

The LED backlight is a newer technology for LCD displays that uses light-emitting diodes instead of a fluorescent lamp. The LED produces white light, but uses no mercury.

Organic Light-Emitting Diode

Although the OLED screen is superficially similar to LCD technology, OLEDs require no backlight; they produce their own light. Because of this advantage, OLED displays can be much thinner than an LCD equivalent. And because a backlight consumes significant amounts of energy, OLEDs help improve battery life in mobile devices. Although the image quality of OLED displays is very good, their working lifetime is currently not as good as LCDs.

A computer speaker is an output hardware device that connects to a computer to generate sound. The signal used to produce the sound that comes from a computer speaker is created by the computer's sound card.

A keyboard is for putting information including letters, words and numbers into your computer. You press the individual buttons on the keyboard when you type.

The number keys across the top of the keyboard are also found on the right of the keyboard.

The letter keys are in the centre of the keyboard.

The symbol keys to the right of the letters include symbols such as the question mark and full stop.

The keys that surround the letters, numbers and symbol keys on the left, right and bottom of the keyboard help you to choose where and how you type.

A Mouse

To hold your mouse, rest your hand over it and put your index finger on the left button and your thumb resting on the side. The cable needs to be pointing towards the computer. The mouse needs to always be in contact with a mouse mat, desk or hard surface.

You use your mouse to move the cursor around the screen. The cursor changes, depending on what you are doing on the computer. As an arrow you use it for moving and selecting things, as a hand for clicking on links when you are on the internet and it becomes an hourglass when you are waiting for the computer to do something.

Single clicking

You single click with the left mouse button to select things. Just quickly left click and then let go of the button.

Double clicking

You double click with the left mouse button to open things, such as a folder. You need to double click quickly, think about the ‘knock, knock’ you do on a door.

Drag and drop

Drag and drop is when you move something from one place to another. 

First select the item with the left mouse button and keep the button pressed down. Then move the mouse and the item on screen will move with the cursor. When you have the cursor and item in the position you want, release the left mouse button.

The item will now be dropped to where the cursor is positioned on the screen.

You use drag and drop to move things around your computer, such as files between folders.

Right button

If you ever accidently click the right mouse button, a list of computer commands will appear. To remove the list just move the mouse and single click the left button.

Laptop trackpad or touchpad

Laptops can have a built in mouse within the keyboard. This is operated by finger touch. This specialised surface is used instead of a mouse and needs only very short finger movements to move the cursor across the display screen.
