Parts of a computer are very similar to parts of the human body. For example, both have input and output devices. The keyboard is the computer’s equivalent of the hand, and the monitor is the eye. The mouse is like the foot, because it moves around on the surface.
Just as we need food to keep our bodies going, computers need electricity to function. And just as our bodies produce waste matter, so does a computer produce heat and noise.

There are other similarities between the two. Both have a central processing unit, or brain, and both have memory. Computers also have something called software, which is like the body’s nervous system. And finally, both need maintenance and occasional repair.
So next time you’re using your computer, think about how similar it is to your own body!
1. HEART – CPU
The heart is known as the Central Processing Unit, or CPU, of the body. Just as a computer needs its CPU to function properly, the body needs its heart to circulate blood and oxygen throughout the body.
The heart is responsible for pumping around 5 liters of blood each minute, and it does this an astounding 100,000 times per day!
The heart is made up of four chambers- two atria and two ventricles. The atria are responsible for filling the ventricles with blood, and the ventricles are responsible for pumping the blood out of the heart and into the rest of the body.
The left ventricle is the most important chamber of the heart, as it is responsible for pumping blood to all parts of the body.
Like a computer, the heart relies on a number of different components to function properly. These components include:
- Coronary arteries: these arteries supply blood to the heart muscle itself
- Valves: these valves open and close to control the flow of blood in and out of the heart chambers
- Cardiac muscle cells: these cells contract and relax to create rhythmic beats that push blood through the arteries
2. BRAIN – RAM
Your brain is a lot like your computer’s RAM. Both are responsible for processing information. But while your computer’s RAM stores data temporarily, your brain can store memories permanently.
Just as you can add more RAM to your computer to increase its speed and capacity, you can improve your memory by using different techniques like mnemonic devices and association.
Your brain is also like a hard drive, in that it records everything you see and hear. The more experiences you have, the more files (memories) your brain will store.
Just as you can delete files from your computer’s hard drive, you can erase memories from your brain by forgetting them or experiencing them again (although this isn’t always recommended).
3. NERVOUS SYSTEM – MOTHERBOARD
The nervous system is like a motherboard because it connects all of the different parts of your body together. It controls everything from breathing and heart rate to movement and emotions.
Your nervous system is made up of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is made up of your brain and spinal cord, while the PNS consists of all the other nerves in your body.
The CNS acts as the control center for the body, sending messages between the brain and rest of the body. The PNS delivers these messages, relaying them from one part of the body to another.
Just as a motherboard connects all of the different parts of a computer, the nervous system connects all of the different parts of your body together.
4. BRAIN – HARD DISK (Long term memory)
Your brain is like a hard drive, in that it stores information for long periods of time. The difference is that your brain can also create new files, whereas a hard drive cannot.
Just as you need to periodically back up your computer files, you need to periodically review and reinforce the memories you want to keep.
The part of the brain responsible for long-term memory is the hippocampus. This region is especially active when you are learning something new or trying to remember something important.
The more often you activate the hippocampus, the stronger the memory connections will be. You can do this by reciting information out loud, writing it down, or rehearsing it in your mind.
Your brain’s hard disk can hold an amazing amount of data. In fact, recent studies suggest that our brains may have up to ten times more storage capacity than we previously thought.
This means that we can store not just years’ worth of memories, but also entire lifetimes’ worth of experiences and knowledge.
The key to accessing this information is making sure that it stays active and “online”. One way to do this is by frequently revisiting old memories.
5. MUSCLES – BUS
The muscles in a computer are very important for the overall function of the system. They are responsible for transferring data and power throughout the motherboard and other internal components.
In the human body, muscles are also responsible for movement and support. They are made up of fibers that can contract to produce force.
Just like in humans, the muscles in computers can become tired or overworked. When this happens, it can cause the system to slow down or even crash. It is important to maintain your computer’s muscles by keeping them clean and cool.
You can do this by using a compressed air duster to remove any dust and debris from the inside of the case. You should also make sure that the fans are working properly and that there is enough airflow through the system.
If you don’t take care of your computer’s muscles, they will eventually wear out and need to be replaced. This can be a costly process, so it’s important to keep them in good condition.
6. MOUTH – SPEAKER / PRINTER
The mouth is an important part of both the computer and the human body. For the computer, the mouth is where the speaker is located. This is the part of the computer that emits sound waves, which allow us to hear what is happening on the screen.
The speaker is essential for listening to music, watching movies, and playing video games.
The printer is another important computer component, and like the speaker, it has a counterpart in the human body. The printer prints documents by spraying ink onto paper.
This process is similar to how our eyes create images by spraying ink onto the retina. Like the printer, our eyes are essential for reading and viewing information.
7. HANDS – MOUSE / KEYBOARD
Mouse and keyboard are both used for inputting information into a computer. The mouse is used to move the cursor on the screen and to select items, while the keyboard is used to type text.
The mouse is similar to the human hand in that it has five fingers that can be moved independently. The mouse also has a thumb, which can be used to click on buttons.
The keyboard is similar to the human hand in that it has 10 fingers, although the fingers on the keyboard are not independent.
8. EYES – WEBCAM
The eye can be compared to a webcam in a computer because they are both devices that capture images. The eye is like a webcam because it takes pictures of what is happening in the surroundings.
It sends the image to the brain which interprets what is being seen. A webcam does the same thing when it takes pictures of people who are using the computer.
9. EARS – MICROPHONE
Ears are essential in both humans and computers for auditory function. In addition to sound detection, the ears also play a role in converting sound into electrical signals that the brain can understand. For this reason, ears are often used as microphones in computer audio applications.
The human ear is capable of detecting a wide range of frequencies, from 20 hertz (cycles per second) up to 20,000 hertz. The average human ear can detect sounds that range from 0 decibels (dB) to 120 dB.
In comparison, most computer microphones can detect frequencies up to 20,000 hertz and are capable of sensing sounds as low as -60 dB or as high as +6 dB. This makes human ears much better at capturing higher frequency sounds than most computer microphones.
However, computer microphones are better at capturing lower frequency sounds than human ears.
10. FACE – MONITOR
When you look at a computer, the monitor is the face. It is the first thing you see and the last thing you remember. Just like our faces, monitors come in all shapes and sizes. The most important part of a monitor is the image that is displayed on the screen.
The quality of that image can be affected by many factors, including the type of monitor, the graphics card, and the resolution.
Monitors use one of two types of technology to create images: CRT or LCD. CRT monitors use a cathode ray tube to generate images. LCD monitors use liquid crystal display to generate images.
LCD monitors are more popular than CRT monitors because they are thinner, lighter, and use less power. However, CRT monitors often have better image quality than LCD monitors.
11. SKIN – SYETEM CASING
The skin is the outermost layer of the human body. It is the first line of defense against infection and other environmental threats. The skin is made up of three layers: the epidermis, dermis, and hypodermis.
A computer system case is the outermost layer of a computer. It is the first line of defense against environmental threats, such as dust and moisture. The system case is made up of three layers: the cover, the main chassis, and the base.
The cover is the outermost layer and is made up of two parts: the top cover and the bottom cover. The top cover snaps onto the main chassis and covers the keyboard, display, and other components.
12. POWER SUPPLY – DIGESTIVE SYSTEM
A power supply is a device that supplies electrical energy to an electrical load. The term is most commonly used in the field of electronics, where it is synonymous with power supply unit (PSU).
A power supply can be implemented as a discrete component or as part of another device. In the latter case, the power supply takes the form of an integrated circuit or other type of semiconductor device.
Just as a computer needs a power supply to function, so does the human body. In order to obtain the energy we need to live, we must eat and drink. Just as with a computer, if our body doesn’t have a steady stream of energy coming in, it will fail to work properly.
13. COMPUTER CASE – SKELETON SYSTEM
A skeleton system is a framework upon which an organism’s body is built. It provides stability and structure, while also allowing movement and flexibility. In a similar way, a computer case serves as the foundation of the computer’s internal components.
It protects these components from physical damage and also facilitates airflow to keep them cool.
Like the human skeleton, a computer case has several key components. The motherboard is the backbone of the system, connecting all of the other components to one another.
Just as our bones protect our organs and muscles, so too does a computer case protect its internal components. The chassis prevents foreign objects from entering the case and potentially damaging sensitive equipment.
The computer parts we’ve looked at in this article “Which Part of the Body is the CPU Often Compared to.” are similar to the corresponding parts of the human body. The motherboard is like the backbone, providing stability and connecting all other components.
The power supply is like the digestive system, obtaining energy from external sources to power the computer. And finally, the case is like the skeleton, protecting internal components from damage and facilitating airflow.
Just as with our bodies, if any of these key components fails to function properly, the entire computer will be affected.
