How a computer Compares to the human Body—Analogies

A computer is a complex piece of hardware with countless moving parts working in harmony—similar to exactly how the human being body functions or operates.

Like the human being body, part of the computer tells the what come do, another component processes things, and another component supplies energy.

This article will dive into the main processing unit (CPU), the graphics handling unit (GPU), the northbridge, the strength supply unit (PSU), the southbridge, and also the system bus.

On a an ext superficial level, the webcam, microphone, case, and USB also contribute come making the computer system whole and totally functional.

When combined, these relocating parts let you browse Facebook, compose a report for institution or game to your heart’s content.

If just one non-superficial component gives up the ghost, the computer system is useless.

The same is true because that the person body. That astounding how dependent and fragile both the human system and the computer system system is.

Let’s jump best in!

The brain of a Computer

The brain of the computer, consisted of of the CPU and also the GPU, is perhaps the most an essential element that the system.

*

The brain of the human, do of assorted lobes, is likewise vital. Both room very facility and responsible for a lot:

The brain of a computer is the CPU and also GPU.

Frontal Lobe and also Temporal Lobe

The frontal lobe and also temporal lobe in the human mind are similar to the CPU in a computer.

The frontal lobe is the regulate panel of our personality and also our capacity to communicate. It controls an important cognitive an abilities such together emotional expression, memory, language, judgment, problem-solving, and sexual behaviors.

The temporal lobe is responsible for encoding and storing memory. It also contains the main auditory complex so that you can understand what you’re hearing.

The central brain of a computer, top top the other hand, is a microprocessor called the CPU. This chip is the central part of the computer and also contains millions of tiny transistors.

The CPU’s project is come crunch the numbers, do the decisions, and problem solve.

In fact, many CPUs today can process an ext than 1 billion instructions in a single second.

Much that the working memory happens right here as well. The CPU and memory work-related together to run programs, i beg your pardon is why a little block of memory, called a register, is constructed into the CPU. That is the fastest kind of computer memory as you can access its components in just a few nanoseconds.

Occipital lobe and Parietal lobe

The occipital lobe and also parietal lobe in the human mind are comparable to the GPU in a computer.

The occipital lobe is the visual handling center. It deals with distance, depth perception, color determination, object recognition, movement, challenge recognition, and memory information.

The parietal lobe procedures sensory info such as touch, taste, and temperature and also helps name: coordinates spatial relations.

The occipital lobe and parietal lobe that the computer system is the GPU, wherein image, video, and 3D handling occurs.

A GPU can be present on a video clip card (also referred to as a graphics card), installed on the motherboard, or installed on the CPU dice (integrated circuit).

The heart of a Computer

In the human body, the love is responsible because that pumping blood transparent the body and also maintaining blood pressure.

While there might be some dispute over what the heart of the computer is, it renders the many sense to to compare it to the northbridge.

The heart of a computer system is the northbridge top top the motherboard.

The Northbridge

The northbridge is among two chips on the motherboard, the various other being the southbridge.

It is responsible for work that require the highest possible performance, such together routing data in the computer and also managing the flow of information.

*

More specifically, it communicates between the CPU and external tools through buses.

Many solution don’t have a traditional northbridge/southbridge configuration any kind of longer.

Instead, lock are combined into the CPU and also simply referred to as a “chipset,” which permits for faster interaction and far better functionality.

As computer systems continue to evolve closer and closer come a device on chip architecture, the CPU will certainly gain more functions.

Therefore, the CPU deserve to be dubbed both the brain and the heart of the computer.

The lungs of a Computer

There’s an ext to the body than just the head and the heart, and much more to a computer than only the CPU, GPU, and also northbridge. Because that example, what around the lungs?

You understand the function of the lungs—they let us breathe, lug oxygen into the body, and also exhale carbon dioxide.

Oxygen is an important element to strength life as the body provides it to burn food molecules. Civilization could not make it through without it.

The lung of a computer is the PSU.

The power Supply Unit

It is clear that the lungs of the computer system are the PSU. Like how humans cannot survive without oxygen, the computer system cannot also turn on without the PSU together it counter the energy everything else runs on.

The strength from the PSU has to go through other systems in the computer before it i do not care useful.

In comparison, the blood flows from the lungs v the arteries and also heart to oxygenate the body’s organs.

If you are experiencing power interruptions or must prepare for one, take into consideration investing in a UPS (uninterruptible power supply), i beg your pardon acts together a standby generator when your primary source of strength fails.

The Digestive mechanism of a Computer

Your body needs much more than just oxygen because that fuel. The digestion system permits your human body to obtain the nutrients and also energy it needs from the food you eat.

It is composed of the gastrointestinal street plus the accessory offal of digestion, i m sorry breaks down food right into smaller and smaller contents until they have the right to be took in and assimilated right into the body.

The digestive device of a computer is the southbridge on the motherboard.

The Southbridge

The closest parallel you can draw to the digestive device is the southbridge. This term must sound familiar since it was mentioned before when pointing out the northbridge.

The southbridge organizes and also controls accessibility to data. Specifically, it implements the motherboard’s slower capabilities, such as the tough drives and also USB—it connects to the CPU with the northbridge.

Much like exactly how the digestive mechanism feeds the body, the southbridge provides the CPU with data for this reason it have the right to do that job.

Think of the data as sugars processed by our body so that your brain can work and also you have actually the energy to perform well during the day, both physically and also mentally.

As technology has evolved, the southbridge became redundant. People now use successors such together the communication Controller Hub (PCH) style bundled through the Intel 5 series chipset in 2008.

The Nervous device of a Computer

The nervous system comprises nerves and devoted cells that transmit signals between different components of the body—virtually the body’s electric wiring.

The nervous device is indistinguishable to the system bus in the computer.

The nervous device of a computer system is the mechanism bus.

The device Bus

The device bus is a communication pathway composed of wires that manage signals moving between the computer system system’s major components.

It consists of 3 buses:

Data bus to carry informationAddress bus to identify where to send itControl bus to determine its operation

The mechanism bus was occurred to provide even much more modularity with decreased cost and was renowned in the 1970s and 1980s.

However, the modern-day computers these days use separate buses modified come meet specific needs.

The system bus background and the ways it has developed to maximize data carry rates between components are fairly impressive.

The most common buses provided today space eSATA and also SATA supplied for difficult drives and also disc drives, PCIe provided for growth cards and video cards, USB offered for computer peripherals, and thunderbolt provided for peripherals associated through a USB-C cable.

The eye of a Computer

The eye of the computer are—you guessed it—the webcam!

The eye of a computer system is the webcam.

The Webcam

The very first webcam was arisen in 1991 in ~ Cambridge university by a young man who simply wanted a new cup the coffee. (Read the story here!)

However, the first commercial camera was marketed in 1994 and also was make by Logitech. Webcams room generally combined into the computer today. 

*

Live streaming with a webcam is just one of the oldest web trends. In fact, the earliest webcam in the world, the san Francisco FogCam, ran because that 25 years.

This webcam began as a student project at mountain Francisco State University and is the longest repetitively operating webcam in the world.

Be cautious with her webcam due to the fact that a hacker can watch the video feed and also infiltrate your privacy.

If you’re paranoid about someone staring at you with your webcam, countless people pick to usage a camera cover just in instance or acquisition anti-virus software.

The ears of a Computer

The ear of the computer system are the microphone.

The ear of a computer is the microphone.

The Microphone

As with the camera, the microphone is usually embedded in modern computers.

You’ll notice, however, the many civilization who have actually a podcast will usage an outside microphone. This is due to the fact that you have the right to buy high-quality exterior microphones and attain a much much better sound.

The earliest “microphones” were acoustic megaphones, and also they were produced in 1665 through the English physicist Robert Hooke.

You may have actually heard that it and also played through one together a kid—it was made of stretched wire through a cup fastened at every end.

The an initial legitimate microphone that allowed proper voice telecommunications to be the carbon microphone.

This was emerged by the notorious Thomas Edison. However, most chroniclers credit a British male named David Edward Hughes v the invention.

The Skin that a Computer

The skin is the biggest organ in the body. It create a barrier so the dirt and also pathogens can’t injury you.

Compare this come a computer system case, i beg your pardon contains and protects all of the contents inside the a computer.

The skin that a computer system is the computer case.

The Case

When human being talk about a computer system case, they’re typically talking about it in relation to a desktop. That is the hard metal or plastic component around “the organs” of the computer. There room several factors why computer instances are essential. 

*

The very first and possible most apparent reason is for protection. Dust and liquids might easily damages the inside of the computer if not for the case.

The second reason is aesthetics. That not precisely pleasing to the eye to be looking at all those cables and also drives that consist of the computer. It’s quite a mess in there.

The 3rd reason is to save the area cool and also have suitable airflow end the computer components.

Keeping the hardware cool is vital because it might overheat come the allude of break down if it gets too hot.

The last factor is to keep the noise level down. Keeping noisy computer system parts, favor the fans, in a closed room within the computer case, is one means to mitigate the noise that they make. And also they deserve to make a lot of noise!

The four of a Computer

The computer’s limbs are anything you can affix to the computer system through USB-C, Thunderbolt 3, or comparable interfaces.

A huge variety of accessories can comprise “limbs,” though part may additionally qualify as “ears and also eyes.”

The limbs of a computer system are the peripherals.

External Peripherals

External peripherals linked by USB-C, Thunderbolt 3, or similar interfaces are nice-to-have features on a computer.

Modern computer systems usually have actually a universal port, so both USB-3 and Thunderbolt 3 can plug right into the exact same spot.

In turn, numerous are confused around the difference between the two.

If friend didn’t currently know, a USB is a conventional connector the transmits both data and power top top a single cable.

You may have actually used a USB-3 harbor to plug her phone right into your computer system on occasion.

Thunderbolt 3 does whatever a USB-C port can, but it is much faster and lets you deliver data up to 40Gbps.

It also allows you to affix external monitors, daisy chain come six additional devices, and support PCIe tools for gaming. Some contact it USB-C’s large brother.

Interestingly, apologize was among the faster adopters of Thunderbolt 3 because that computers.

Now, an ext and much more PCs room coming through Thunderbolt 3 assistance as well.

However, not every agency is jumping top top board since to usage Thunderbolt 3 since you have actually to achieve certification native Intel.
