A desktop computer is the most commonly purchased type of IT hardware by small businesses. Hardware costs are determined by their specifications, which are determined by critical components.

You need to determine the specifications of critical components when you purchase PC hardware.

Central processing unit

The computer’s driver is the processor. The speed of processors is measured in gigahertz or GHz. The faster the processor will run, the higher the GHz. The fastest processor should be purchased, but multi core processors with two or more cores will usually suffice for most business functions. Multicore processors with multiple cores running at speeds up to 2 GHz and above will work well. Higher processing speeds and more CPU cores improve the computer’s perceived speed.

Random access memory (RAM).

To run programs, the processor needs memory. The RAM will determine how fast your computer runs when running multiple programs simultaneously. It would help if you had enough memory on your computer to maximize the processor speed. For modern software, at least 4 GB (GB) is required. 8 GB or more is recommended for those that use more memory-intensive software, such as design or video editing.

Hard drive

The hard drive stores data that you create for your business as well as programs that you use. 500GB is the minimum space an office computer should have. Solid state drives (SSD) are standard on all new laptops and performance computers. These drives are quiet because they don’t have moving parts. They are also five to eight times faster than standard magnetic hard drives on desktop computers. SSDs can provide significant performance benefits, but the price per GB can be up to three times as high for the same storage. An SSD can offer a significant performance advantage over a standard desktop or laptop. This is why it is often recommended that you include one.

External plug-ins such as USB memory sticks or portable external hard drives can be used to augment your computer’s storage needs.


Monitors the computer’s display panel. Modern monitors are equipped with Liquid Crystal Display (LCD) technology. Usually, monitors are measured diagonally in inches. This is typically 22, 24, or 27 inches. Ultra-wide or larger monitors can allow you to view two documents simultaneously on the screen. The cost of the LCD technology and whether you need accurate color reproduction or high refresh rates will determine which one you choose.

A monitor’s aspect ratio is the ratio of image width to height. The most common aspect ratio of monitors is 16 to 9. Still, specialist purposes like CCTV monitoring or movie editing may require other aspect ratios.

You will usually receive the keyboard and mouse as part of a bundle. However, you might be able to choose wireless devices that make your desktops neater.

Alternative computers to traditional desktop PCs are available, such as Apple Macs. Initially designed for desktop publishing, they can also be used as a general office system.

Computer users are most familiar with the components of the computer we use every day: the input and output devices.


Initial computers accepted only “punch cards” for input. Computer scientists had to meticulously punch out their instructions, then feed them into the computer.

A punch card was used to input Fortran programs onto an IBM mainframe computer in the 1970s.

Computers have advanced a lot since the 1970s. We can now use a variety of devices to input data into them. The keyboard, mouse, or touch screen are the most popular input devices.

Many other input devices are available, including scanners for image data and microphones that capture sound waves.

Computers can also get input from the environment through “sensors,” such as motion sensors, which detect movement changes.


After the CPU has finished processing the data, the CPU will often output the result.

The computer monitor is a standard output device. It displays text, images, and user interface elements.

A computer monitor is showing a calculator program. This calculator calculates that 2 + 2 = 4.

A computer can output data in many different ways. The output device must be able to interpret a stream containing 1s and 0. It can transform that data into any other format, such as headphones, printers, or projectors.
