Desktop computers are a physical computer that you place on a desk with a monitor, keyboard and mouse. They can be connected to a network and used to access online files or programs. They are powerful enough to run complex mathematical calculations, as well as stream videos and play games. There are many types of desktop computers, from the sleek and minimalist designs of all-in-one PCs to towers that occupy a large area on your home or office desk. Some have separate graphics cards, while others have integrated ones. You can upgrade your computer parts over time, such as increasing the amount of memory or installing a faster processor.

The earliest desktop computers were so big they took up entire rooms. Since then, they’ve become much smaller and more compact. You can even get a small, portable desktop known as an NUC (next-generation computing unit), which is designed to be built into an entertainment center or living room TV set. The best desktop computers are the ones that meet your needs for processing power, screen size and other features.

If you plan to use your computer for streaming movies and other digital content, look for a desktop with a high-resolution display. These models offer better color and contrast than the standard laptop displays, as well as a larger screen size that can give you a more immersive experience. These computers also tend to have a more extensive selection of ports than laptops, making it easier for you to connect peripheral devices like printers and external hard drives.

For productivity work, look for a desktop with a fast processor and plenty of RAM (random access memory). You’ll want at least 8GB of memory to handle most tasks, but 16GB is better if you’re planning on running multiple demanding applications at once. For the most performance out of your desktop, look for one with a discrete graphics card instead of an integrated one. Discrete graphics are better at handling high-definition and ultra-high-definition video editing, but they’re not required for mainstream gaming or light video editing.

You can find a desktop to suit almost any budget, from the premium Dell XPS models to affordable Inspiron machines that are great for basic Internet browsing and word processing. Most desktops come with a mouse and keyboard, but you can buy additional accessories to improve your user experience. Some users prefer to use a gaming mouse and keyboard, while other people may opt for a wireless or Bluetooth mouse and keyboard. In addition, some people might prefer a desktop with built-in speakers for a more complete audio experience. You can also opt for a headset to enhance your virtual reality experience. If you need assistance, Dell provides phone and online technical support with experts available to help you resolve any issues. You can even purchase additional support to keep your desktop running at peak performance. The company’s Ultimate Care subscription offers a number of services, including unlimited hardware repair and replacement for an extended period of time.
