So, if you’ve ever wondered what’s going on inside your computer and how does a computer works, this guide is for you!
Computers have become an integral part of our daily lives, and we rely on them for various tasks, ranging from work to entertainment.
What Is a Computer in Layman’s Terms?
Well, you have read a lot of definitions and technical article defining what is a computer and how does it work? but still, you reached here in this post, right? Lemme explain it in the simplest way possible.
A computer is like a magic genie in a box. You tell it what you want it to do, and it’ll make it happen, as long as you don’t rub it the wrong way (or spill coffee on it). It’s like a personal assistant that never complains (unless it’s crashing, in which case it’s throwing a tantrum).
It’s the ultimate multitasker, able to juggle dozens of tasks at once without breaking a sweat (unlike your boss). And let’s face it, without computers, we’d be lost. Literally. Have you ever tried to navigate a new city without Google Maps? It’s like trying to find your way out of a maze blindfolded.
So, long story short, a computer is a modern-day miracle, and we should all be grateful for the technological wizards who make it possible (even if we sometimes want to throw our computers out the window).
Technically, a computer is an electronic device (similar to a calculator but much more powerful) that processes information according to instructions given to it by a user. It can perform various tasks, such as storing data, performing calculations, displaying information, and communicating with other devices.
Essentially, a computer is a machine that can be programmed to perform specific tasks automatically. The term computer comes from the Latin word “computare,” which means “to calculate.” Nowadays, computers are used in many different fields, from science and engineering to entertainment and communication. They have become essential tools for modern society, and their capabilities continue to expand as technology advances.
Despite the widespread use of computers, many people don’t know how they work or how they operate.
In this blog post, we will explore the step-by-step working of a computer and shed light on the operations that take place within the machine.

Input
The first step in how a computer works is input. Input refers to the process of entering data into the computer. This can be done using various devices, such as a keyboard, mouse, scanner, or microphone. The input devices translate physical actions into digital signals that the computer can understand.
Processing
Once the computer receives input, it processes the data. The processing involves performing various operations, such as arithmetic and logic operations, on the input data. The central processing unit (CPU) is responsible for performing these operations. The CPU is the brain of the computer, and it controls all the operations within the machine.
Storage
After processing the data, the computer stores it in memory. Memory refers to the space where the computer stores data temporarily. A computer has two types of memory: random access memory (RAM) and read-only memory (ROM). RAM is volatile memory, meaning it loses its contents when the computer is turned off. ROM, on the other hand, is non-volatile memory, which means that it retains its contents even when the computer is turned off.
Output
Once the computer has processed and stored the data, it produces output. Output refers to the information that the computer displays, prints, or sends to other devices. This can be done using various output devices, such as a monitor, printer, or speakers. The output devices translate digital signals into physical actions that we can see or hear.
Communication
The final step in how a computer works are communication. Communication refers to the process of exchanging data between computers or other devices. This can be done using various communication devices, such as a modem, network card, or wireless adapter. The communication devices translate digital signals into analog signals that can be transmitted over the network.
The hardware components of a computer are the physical parts that make up the machine. Here are the main hardware components of a computer:

Hardware components responsible for working of a computer system.
The hardware components of a computer are the physical parts that make up the machine. Here are the main hardware components of a computer:
Central Processing Unit (CPU)
The CPU is the brain of the computer, and it’s responsible for performing all the processing operations. It’s a small chip that fits onto the motherboard and is the most important component in determining a computer’s performance and responsible for the whole working of a computer.
Random Access Memory (RAM)
RAM is the temporary storage space used by the computer to store data that’s being used at the moment. The CPU can access this memory quickly, which is why having enough RAM is essential for a computer’s speed and performance.
Hard Disk Drive (HDD) or Solid State Drive (SSD)
These are the devices where data is stored permanently. The HDD uses spinning disks to read and write data, while an SSD uses memory chips instead of moving parts, making it faster and more reliable.
Motherboard
The whole working of a computer system depends on this motherboard which is the main circuit board in a computer. It connects all the components together, and it also has some built-in components, such as the sound and network cards.
Power Supply Unit (PSU)
The PSU supplies power to the other components of the computer. It converts the AC power from the wall outlet to the DC power that the computer needs.
Graphics Processing Unit (GPU)
The GPU is responsible for processing graphics and video. It’s a separate chip from the CPU and is particularly important for gaming or graphic design. I guess for you must’ve heard this term before as the games you play in your PCs is powered by this very GPU.
Input and Output Devices
These are the devices used to interact with the computer. Examples of input devices include the keyboard, mouse, and microphone, while examples of output devices include the monitor, printer, and speakers.
Overall, these hardware components work together to make a computer function. Each component has a specific role to play, and they all rely on each other to work properly.
