Desktop Computer Hardware Components

Do you own or work in an office setting that requires a wide variety of devices? If so, you probably understand how costly these devices can be. It would cost too much to stock the supplies necessary for each employee or purchase several different types of devices if you have a large number of employees. To save money, many office managers are choosing to implement discount programs into their office equipment policies. These programs allow office managers to receive discounts on the products they buy from a specific retailer.

What are some of the types of devices most often purchased with these discount programs? Let’s look at a few of the most common devices used in the workplace. As mentioned above, computer technology encompasses many different types of computer devices you can physically touch. This includes devices like the following: desktop PCs. laptop computers.

Pointing devices. These are small computer cases containing a mouse, keyboard, or pointing device. Most modern tablet computers contain one or more pointing devices. Pads, touch screen displays, pens, stylus, USB sticks, and other pointing devices are commonly included with new laptops.

Output devices. These are computer hardware and software used to send information from one location to another. They include things like printers, faxes, modems, scanners, hard drives, and other peripheral components.

Computers and processing systems. These are pieces of hardware that perform specific tasks. Examples of computers and processing systems include: personal computers, servers, laptop PCs, desktops, workstations, and network servers. Peripheral parts which make up these devices include: memory, input and output devices, expansion slots, external peripherals, and physical processors. The computer memory is the storage for data and instructions that are processed during execution of the program or application.

Non-volatile memory. Non-volatile memory or NVRAM is used to hold data and instructions. They are not affected by computer crashes or restarts and are not subject to computer viruses. They are also referred to as volatile memory or flash memory. Non-volatile devices may be more expensive than volatile memory devices but have more reliability because they do not get replaced after every use and are less likely to suffer damage.

Digital devices. Digital devices include e-reader devices, digital cameras, digital video camcorders, DVD players, and video game console. Digital devices can be combined with electronic paper readers and tablet computers to form portable electronic reading devices. Digital devices are generally more expensive than traditional computer hardware and are used mostly by businesses.

Peripheral devices. Various peripheral devices are attached to a desktop computer through PCI/PCIe slots, USB ports, or wireless adapters. Examples of peripheral devices include printers, scanners, keyboards, monitors, mice, external drives, and headphones. A printer is a device that is used to print documents. Monitors are used to detect changes in the world around them and adjust their position to catch the information appropriately.

Storage devices. Traditional computer hardware devices are categorized into storage devices and output devices. Storage devices include hard drives, solid state drives (SSD), optical drives, floppy disks, CD-ROMs, and tape backup disks. Output devices consist of printers, monitors, keyboards, mouse, USB devices, digital cameras, video game systems, audio devices, video input devices, portable media players, scanners, printers, and USB storage devices. All storage devices, output devices, and input devices play an important role in the operation of a computer.

Direct input devices are those that send and receive information from the application software. Indirect input devices send information to the application software. Output devices, on the other hand, are those that bring information to an end user through mechanical pressure, heat, or a vibration. In the case of pointing devices, those devices that are used to point devices at information.

The Game controller device is an output device that is connected to a computer. It receives electronic pulses and uses them as cues from the game that determine where a player should be at a particular moment in the game. It also receives continuous radio signal from the game controller unit. The output device is a device that brings the information from the game controller unit directly into an input device.

Computer input devices include the keyboard, mouse, pointing devices, image capture device, video output device, sound output device, speech recognition device, and digital camera. Computer output devices include printer, monitor, keyboard, USB devices, scanners, video game system, video input device, and game controller unit. All of these output devices play a very important role in operating a typical desktop PC. Each of them can be categorized into either direct input or indirect input. Direct input devices refers to any item that allows a user to control a computer process by supplying signals such as keystrokes, mouse button clicks, and game controllers.
