What to look for when buying a desktop computer

There are many different types of desktop computers on the market today. The first thing you need to do when buying a new computer is figure out what type of computer you want. You might need something small, powerful or affordable—it all depends on your needs and budget. Here’s how to find the right one for you:

What to look for when buying a desktop computer

When looking for a desktop computer, it’s important to understand the components of your new machine. Computer components work together in order to create an efficient and powerful system that can be used for many years without needing major upgrades or repairs. There are several different types of these components:

  • The motherboard is where all of the internal components are attached together with cables and other wiring (like RAM). This is where you’ll find things like processor, graphics card, hard drive(s), fan(s), etc.
  • The CPU (central processing unit) is responsible for running software; it processes instructions sent from programs on your operating system or some other application program through memory into electrical signals that are transmitted through wires into other parts of the computer so they can be processed by other parts like graphics cards or sound chipsets within this same system board but also within other external devices connected via USB ports located near where I just mentioned above!

Picking the right computer

Now that you know what to look for, it’s time to start your search. The first thing you should do is make sure the computer has enough power to do everything you need it to do. This will depend on how many programs and applications you plan on running at once, so make sure that your new desktop can handle all of those things without breaking a sweat.

Next up is portability: will this be an external device or one built into your desk? If it’s built in, consider whether or not there are any ports available for connecting external peripherals like printers and storage devices (if needed), as well as whether there are any dedicated USB 3 ports if more than one external hard drive would be connected at once—this could save time since users won’t have multiple cables across their desks! Also keep in mind how much space there is between each component so nothing gets lost in translation when moving around during installation.”

1. RAM (Random Access Memory)

RAM (Random Access Memory) is the memory that your computer uses to store data. The more RAM you have, the faster your computer will be able to run programs and applications. Most computers come with one or two gigabytes of RAM, but if you’re looking for a new desktop computer and want better performance, it may be worth investing in more RAM.

A common misconception is that having more than 256MB of RAM means better performance—but this isn’t always true; there are other factors involved such as: how fast your processor runs compared with other processors in its class; whether or not there are other tasks running simultaneously; etcetera! So while it’s true that having more than 256MB does make things run smoother overall because all those tasks can access their respective parts of memory at once instead taking turns getting accesses at each step along their own path through code paths being executed simultaneously within different threads (called processes), don’t assume anything else about this relationship between various resources such as CPU cores versus mainboard processors versus graphics card frame buffers

2. ROM (Read Only Memory)

ROM (Read Only Memory) is a type of non-volatile memory used to store permanent information on the computer. This means that when the computer is turned off, it will still retain its data from when it was last powered on. In contrast, volatile memories such as RAM lose their contents when power is removed from them.

ROM can also be used for storing BIOS or firmware updates — programs that are loaded into memory by booting your operating system and are responsible for initializing hardware components such as motherboards and graphics cards before they begin executing tasks within an application window or desktop environment.

3. HDD (Hard Disk Drive)

The hard drive, or HDD, is the most important component of a desktop computer. It’s where your operating system (OS) and applications are stored. A good rule of thumb: You should always have at least 500 GB of storage space on your hard drive as well as a solid state drive (SSD).

The speed at which you want to run your computer depends on how many programs you need to run simultaneously and how demanding they are in terms of graphics performance or processor usage. For example, if you frequently play video games with high resolutions and settings, an SSD might be necessary to ensure smooth gameplay performance from start to finish; if all you do is browse social media sites like Facebook or Twitter for hours every day then an HDD would work just fine—just make sure that it has enough RAM capacity so that applications aren’t having trouble loading because there isn’t enough memory available for them all at once!

4. Display unit

A display unit is the part of your computer that actually displays images on a screen. It’s one of the most important parts because it determines how good-looking and vivid your images will be, so it’s worth taking some time to find out what specifications you want in this area.

The size of your display unit refers to its width and height; these measurements represent how much space there is between each corner (or side) of your monitor/screen. The larger these numbers are, then more room there will be for text and graphics when viewing things such as web pages or documents.

Resolution refers to how many pixels there are per inch—the higher resolution means smoother scrolling through longer documents like PDF files without losing any detail along way down page edges; however at lower resolutions you might find yourself scrolling back up repeatedly if something has been missed out during reading due mainly because text appears blurry rather than sharp lines against backgrounds which makes reading difficult if not impossible while still maintaining good quality images overall.”

5. CPU (Central Processing Unit)

The CPU is the brain that runs your computer. It’s responsible for everything from processing data to handling graphics, and it’s measured in GHz (gigahertz).

The speed of your CPU can be determined by how many cores it has and what each core does. For example, if you have an Intel Core i5 processor with 8 cores and two threads per core, then this means that the total number of threads across all eight physical processors equals 16 – 2 x 8 = 12 threads.

Multiple cores = more processing power => faster performance; but multiple CPUs will generate more heat than single-core setups

6. Mother board

The motherboard is the heart of your computer. It determines how many memory slots and expansion slots are available, as well as how many processors can be installed and whether or not you can use a fanless design.

  • Motherboard: The main component in a desktop PC that makes all other components work together. It’s responsible for interfacing with the rest of your hardware (like graphics cards, hard drives), and it also houses important chips like RAM (random access memory) or CPU chips that control processing power while running programs on your computer.
  • Processor: The part inside CPUs which interprets instructions given by software applications such as word processing programs or video games; also known as Central Processing Unit (CPU). For example: if you’re playing an action game like Red Dead Redemption 2 then there will be multiple processes running simultaneously so they need lots more RAM than just one instruction at once!

7. Cache memory and processor speed

Cache memory is a type of RAM that stores information in order to reduce the bandwidth needed to access it. This means that data will be processed much faster than if it were not cached, which makes having more cache memory a good idea for any computer user.

Processor speed refers to how fast your processor can perform mathematical calculations, such as those required by graphics programs or video games. The higher your processor’s clock speed is, the better it can handle those tasks; however, keep in mind that most computers don’t come equipped with high-powered processors like those found in laptops and gaming consoles—they’re typically found only inside desktops instead!

How does this relate back again? By increasing your desktop’s cache size along with its processor speed (you may also want one now), you’ll be able make sure everything runs smoothly even when doing long-term work sessions without having any problems pop up later down road due

8. Networking capabilities

The best desktop computers will also be able to connect to the internet and other computers, printers and other devices. This is important because it lets you share files with others on your network or use remote access features like file sharing.

If you’re thinking of getting a new computer, look for one that includes networking capabilities as well as hardware acceleration for video games and fast boot times when starting up (which saves time).

9. Expansion ports, slots and bays

Before you make a purchase, it is important to note that your motherboard will have the most expansion ports available. However, additional expansion slots and bays can be purchased separately for $20–$50 each.

The motherboard has two or three PCI Express x16 slots (three if you have an SLI graphics card). You can also add another PCI Express x16 slot if you need more than four graphics cards installed at once on your computer—a lot of high-end gaming PCs come equipped with this feature as well as many laptops with multiple graphics cards built into them.

There are also several other types of slots available: USB 3.0 ports; FireWire 400/800/1600 connections; IEEE 1284 serial port connections (if your computer uses one); IDE connectors for hard drives; SATA power connectors for external hard drives; eSATA ports for external hard disks and optical drives


  • What to look for when buying a desktop computer:
  • RAM (Random Access Memory) – RAM is the “working” memory on your computer. It’s where all of your applications and files are stored, so it’s important that you get enough RAM for those items. The amount of RAM will determine how many programs can be open at any given time, as well as how much space they take up on your hard drive.
  • ROM (Read Only Memory) – ROM is like a stock market, where stocks are bought and sold by investors in order to make money off them later on down the line. Your computer uses ROM to store its basic operating system functions such as booting up Windows or opening folders—it doesn’t matter if these things happen quickly or slowly because if something goes wrong with one part then everything else stops working too!

With all the different types of computers out there, it can be hard to know where to start. This article should help you come up with an idea of what kind of computer is right for your needs. If you’re unsure about any aspect, don’t hesitate to ask questions!
