What Is The Architecture Of My Computer

Inner Workings Of A Computer

To understand the architecture of your computer, you must first understand how it works. In its simplest form, a computer is simply an electronic device that inputs, processes, stores and outputs data. Depending on the specific model, the data can be processed in various ways. This is where the architecture comes into play.

An important factor in understanding the architecture of your computer is the type of hardware it contains. Hardware refers to the physical components of a computer system. This includes the CPU, RAM, hard drive and other components such as sound cards and network adapters. Depending on the model, you may also have additional hardware components, such as graphics cards and other specialized components.

The hardware, or physical components, is linked together by an architecture. This will dictate how data is processed and how information is stored and transferred. The architecture of your computer will vary depending on the model and type, but generally speaking, it can be divided into three core components: the motherboard, the CPU and the RAM.

The motherboard is the main circuit board in your computer, connecting all of the other components together. It is responsible for controlling the flow of data and electrical power throughout the system, thereby allowing the components to communicate with each other. It also contains what are known as “chipsets” which are responsible for controlling the speed of the system.

The Central Processing Unit (CPU) is the brain of the computer, processing instructions and performing calculations. It is usually a multi-core processor, containing multiple cores with dedicated pathways that allow instructions to be processed faster and more accurately.

Finally, Random Access Memory (RAM) acts like the computer’s short-term memory, storing data that is accessed quickly and frequently. It is usually the size of an external flash drive, and is usually installed directly onto the motherboard. It performs significantly faster than your computer’s hard drive, allowing your computer to access data quickly.

Windows: The Operating System

The next important factor in understanding the architecture of your computer is the operating system. The operating system, or “OS” for short, is a type of software that runs on your computer. It is responsible for managing the computer’s hardware and software resources, as well as providing an interface for the user to interact with the system. The two most popular operating systems are Windows and macOS.

Microsoft’s Windows operating system is the most widely used OS in the world, and is installed on most PCs around the world. It is built around a kernel, which is the core of the OS, and provides the interface between hardware and software components. It is designed to be user-friendly, and provides users with an intuitive way to interact with the system.

Windows also provides access to different programs, applications and services through its Windows Store. These are applications that can be downloaded and installed onto the system, allowing users to customize the computer to their needs. Windows also provides security features such as Windows Defender, a built-in anti-virus solution, providing an extra layer of protection against malicious software.

Finally, Windows offers an intuitive user experience, with an easy to use graphical user interface (GUI). This allows users to interact with the system in a more organized manner, making it easy to navigate menus, open applications, and access settings.


The other major operating system available is macOS, developed by Apple Inc. and running exclusively on their line of Mac computers. Like Windows, it is built around a kernel, and provides the user with an intuitive interface.

MacOS is slightly different from Windows in the sense that it is clinically more secure, due to the fact that Apple controls both the hardware and software. As a result, macOS is also more restricted and does not allow for as much user-customization as Windows does.

The macOS user experience is similar to the Windows user experience, except for the fact that macOS comes preinstalled with many more applications, such as the QuickTime media player and the Safari web browser. It also has a more accessible file system, which is easier for users to navigate.


The capacity of your computer is determined by the type of hardware it has. The CPU is the main component responsible for determining the speed and power of your computer, so the faster the CPU and the more cores it has, the more powerful it will be. Additionally, RAM is also a major factor in determining capacity, with more RAM resulting in better performance.

Storage capacity, on the other hand, is determined by the type and size of the hard drive installed in the system. Hard drives come in various sizes and speeds, with the most common being the SATA3 variety. This can range from 500GB up to 8TB for desktop computers, which should be more than enough for most users’ needs.

Additionally, capacity can also be increased through the use of external storage devices, such as USB flash drives or external hard drives, allowing you to store data offsite. This can be especially useful for backing up important data, or for transferring files from one computer to another.

Graphics Cards

The graphics card is the component responsible for producing the images you see on your screen. It is installed directly onto the motherboard and allows the computer to process and display 3D images and other high-resolution graphics. Graphics cards come in various forms and sizes, ranging in performance and cost. Entry-level graphics cards are usually seated on the same circuit board as the CPU, whereas high-end graphics cards usually require a dedicated slot on the motherboard.

Graphics cards are especially important for gamers, who require the highest performance possible in order to play the latest games. It is generally considered good practice to install a dedicated graphics card into your computer, as the graphics card installed on the motherboard may not be powerful enough to run certain games.


Software refers to the programs and applications installed on your computer, and is a key factor in understanding the architecture of your computer. The most widely used software is the Microsoft Office suite of programs, which can be purchased as a single license and installed onto multiple computers. However, there are also freely available alternatives such as the OpenOffice suite and Google Docs.

Additionally, there are specialty software such as image and video editing programs, audio recording programs, and more. Whether you need to perform a specific task or simply wish to customize your experience, it is worth investing in some of these programs.


Understanding the architecture of your computer is essential in order to ensure its longevity and performance. By understanding the components that make up your computer, you can identify problems, upgrade or install components, or simply increase your understanding of the inner workings of your machine.
