Over the years desktop computers have become less mainstream as compared to laptops and tablets. Still, the pros of computers in many aspects outweigh the benefits of owning tablets and laptops. They allow the user to work on bigger screen, are less costly to repair and provide you with a better working environment. Most people use computers for internet usages such as for checking emails, social media, streaming media content, and other such casual tasks. While many use it for productivity tasks such as writing, editing and putting together a presentation for work or school. Others might use it for playing videos and audios that are either stored on CD or DVD or is stored locally as digital files such as MP3 audio files.

This guide aims to cover the basic items to examine and basic elements to be kept in mind for you to make an informed purchase.

Monitors
Monitors are obviously a necessity while buying a CPU, without a monitor the CPU is of no use. If you buy an all in one, the monitor will be included but the buyer still needs to consider the various characteristics of the screen. Monitors today are based on LCD display, that boils down the real issue to size and their cost. Colour as well may be an important factor for those who are going to use their desktops for creative work. Most common monitors nowadays come at 24-inch screens with a high definition of 1080 pixels. HP Pavilion 22 CWA is a suitable choice for those who are on a budget. With great video and picture performance and an anti-glare treatment, this 21.5-inch ultra slim monitor is perfect for every major need for desktop computer users without being heavy on the pocket. This 21.5-inch ultra-slim monitor checks off every major need for desktop computer users without breaking the bank. First off, it has great video and picture performance, thanks to its full HD 1080p resolution, LED backlighting and ultra-wide IPS technology. The Pavilion 22cwa also has amazing 8,000,00:1 dynamic contrast that provides rich colors, an anti-glare treatment and a thin bezel that keeps your attention on the display, not the design of the monitor. Connectivity options are basic with VGA and HDMI inputs, but this will satisfy most computer owners. More than 1,700 Amazon reviewers have given this monitor an average 4.5-out-of-5-star rating and have surprised many buyers with how good it looks for the price, so you can’t go wrong with

Memory
For memory, it is imperative to consider the type and number of software you intend to run on the system. However, normally one would want to have more RAM. Also, the type of memory also is imperative while considering a desktop computer. DDR4, for instance, aims to provide faster processing. To check for memory erstwhile purchase is pertinent to long-term computer usage since memory is not interchangeable. Another thing to consider is how much memory can a system support. Many desktop computers come with four to five memory slots on the boards with modules installed in the pair. These slots can play an important role in how a person could upgrade their memory.

Processors:
Processors are the heart of a computer. They determine the processing capability of a computer and speed. However, different processors work differently on various models which makes it hard to determine how good a machine really is. Dell’s Inspiron's 3000 combinations of a plug-and-play setup, 6th generation Intel Core i5 2.7GHz processor paired with 12GB RAM and a 1TB hard drive all make for a great unit. The processor and RAM are two of the most important components when you're dealing with the swiftness of a computer. If you want an ultra-fast machine, then those two pieces of hardware should be looked at first and foremost.

Hard Drives
Many desktops nowadays have started to use solid-state drives or storage or caching. Main elements of hard drives are size and speed. The larger faster drive would entail better performance as well as great capacity. For desktops, it is recommended to have at least 1TB or more storage space these days. In terms of speed, on the other hand, most run at 7200rpm, but there are some speed drives that consume lesser amount of energy. In some cases, solid state drives (SSD) can be used for caching that could help to improve the overall performance of the computer. SSD uses a series of flash memory modules instead of a magnetic disk to store the data, allowing for faster performance. These are still quite rare in desktops as they are generally too expensive and provide less overall storage space. Another form of the hard drive found in many computers is the solid state hybrid drive (SSHD). It takes small SSD and puts it into the hard drive, which in turn boosts performance.

Video Cards
Video card technology is constantly evolving. For users who do not make much use of 3D graphics, then the integrated graphics will do the job just fine. On the contrary, for gamers, an efficient graphics card matters the most in any computer. While many PCs can easily support 2560 x 1440 p resolution display, it is still hard for many integrated solutions to drive a display at Ultra High Definition. If a user wants to use such high-resolution display, he must check maximum display resolution for any video processor erstwhile making the computer purchase. On the other hand, individuals who are aiming to use the computer for creative work such as graphic design or video editing will definitely want a video card with more features. For designers, the high-resolution capability is suitable with a memory of 2GB on the graphics card. Similarly, games like solitaire and candy crush do not require a high-end video card, but for serious gamers who intend to run a game on ultra HD then they should look for a higher end graphics card computer. Dell Inspiron 5680 in this regard seems to be a suitable choice.

External (Peripheral) Connectors
Computers now a - days use peripheral connectors to connect to various devices instead of internal cards. Before purchasing the buyer should check to see how many and what kind of external ports are present on the computer which could be used easily. It is also suitable to get a CPU with a minimum of six USB ports. Many systems such as Apple use Thunderbolt which can be used especially for external storage.
