What Part Of The Computer Is The Brain

Don't Miss

Cpu: Central Processing Unit

Computer MCQ’s Part 8 || which part of the computer called brain ? in Hindi/English

The CPU is basically like the brain of a computer. It processes all the information on a computational level.

It takes information from the RAM and processes it to perform the tasks required from the computer.

It is usually seated in a socket that utilizes a lever or a latch with a hinged plate with a cut out in the center to secure it onto the motherboard.

It has many copper pads underneath it for the socket contacts to push up against them to make electrical contact.

There are other ways CPUs can be attached to the motherboard.

Here are some common examples:

  • ZIF : Although this a more desirable socket, they are mostly found on older computer motherboards. A lever-operated mechanism to clamp the pins of the processor.
  • PGA : It is also a ZIF socket but has a different pin pitch and contains a different pin count.
  • LGA : More commonly found on motherboards today. A levered hinged plate with a center cut-out clamps down on the processor.
  • BGA : The CPU is soldered directly onto the motherboard. This makes it a non-user swappable part. It is susceptible to bad connectivity.

A processor generates a decent amount of heat, especially when it is working under high loads.

It will run even hotter when it is set to a higher clock speed to make it run faster. This is called overclocking.

This is why a heatsink and fan assembly are required to draw the heat away from the processor and distribute it to thin sheets or fins of metal for the fan to cool down.

Reasons Behind Forgetting Things

The brain can store a large sum of data in it, but some things are lost. Forgetting is as essential as retaining something. It helps make new memories and move on. Otherwise, we will never progress into the future and cling on everything traumatic we remember. Sometimes we even forget the memories we cherish because this is how the brain works. It lets go of memories so future memories can be made. This is the reason why we even forget our most heartbreaking break up after a while or even our most cherished birthdays.

Here are the three ways it can happen.

Passive Oblivescence

This is the process of losing memory when the neuron connection weakens over time. With aging or when we do not actively recall a memory, the neuron’s link is lost. It can also happen when we lose the stimulus to the mind. The memory might still be there, but we are not able to access it.

Target Forgetting

This happens when our brain actively prunes and discard certain details of a memory. For example, when we learn a new piece of information that contradicts the previous one, the pleasant memory is retained. The conflicted one is dismissed. With target forgetting, we also eliminate our conflicted believes and welcome new perceptions.

What Are The Parts Of The Brain

Every second of every day the brain is collecting and sending out signals from and to the parts of your body. It keeps everything working even when we are sleeping at night. Here you can take a quick tour of this amazing control center. You can see each part and later learn what areas are involved with different tasks.

Here Are The 12 Main Parts Of A Desktop Pc Computer

Several years ago, I used to build custom computers as a hobby. I would order separate computer parts and connect them together on a PC motherboard inside a computer case to assemble a custom PC.

From that hobby I learned so much about computer parts, and it was so exciting to plan, design, find the best parts and finally assemble a custom-built computer machine.

As you will see below, Desktop computers are made up of a lot of different parts that work together to perform for you.

What I will try to do in this article is to teach you some basic functions of the main computer parts so when you open a computer up, you can identify these different parts and know what they do.

Lets take a look at the main components of a desktop computer below:

Network Interface Card Or Wifi Card

The future of perception: brain

The network interface card is also called the NIC . This part is what gives a computer its networking capabilities.

It can allow a wired Ethernet connection or a wireless WiFi connection to a LAN . Today, most computers have wireless NICs that are designed for WiFi connection. Also, you can insert a wired Ethernet NIC card in a motherboard slot to get additional network connectivity ports if needed.

Living Unconsciously As Our Brains:

Up until this point in the article, we have examined the characteristics similarly shared by both brains and computers. For the antagonists of the computer-brain theory, there is one substantial argument that helps show how the human mind and its mechanical counterpart differ in their operational capabilities. Unlike computers that objectively operate based upon software, algorithms, and rules, humans are equipped with the unique feature of mindful consciousness, or the ability to experience life subjectively while being aware of themselves and the world around them.

While neuroscientists are quick to classify consciousness as a function of the human brain, although they cant verifiably say what it is or what its purpose may be, spiritual seers and sages long ago came to believe this mindful state is who we are at the core of our beings. Yet still, regardless of if consciousness is or isnt who we truly are, it is from our habitual ways of living unconsciously as our brains that problematic cognitive patterns arise. Unfortunately, all too many people remain unaware of their true consciousness capabilities and go about their lives on mental autopilot without having any idea as to how their cognitions are affecting their state of wellbeing.

Mental Illness And The Broken Brain

Understanding that mental illness, such as depression, is an organic disease can help people seek treatment. Accepting that you have a medical condition is easier than accepting that you have a moral defect. Nonetheless, the cerebral mystique can also cause people with mental illness to believe themselves broken people, incapable of recovery. Sometimes this self-stigmatization can be harder to fix than people who believe themselves morally flawed. Focusing on the brain ignores cultural and environmental factors, as well as non-physical therapies.

General paresis of the insane, a diagnosis which was once applied to a large fraction of the people admitted to an asylum, was treated as a mental disease until the early 20th century when it was shown to be caused by advanced syphilis. This is a clear example of a mental disease of biological origin outside of the brain acting through the brain by the degeneration of neurons, but not caused by the brain. It is a brain disease, a biological sickness, and an environmental condition simultaneously.

Some mental diseases such as schizophrenia have a large heritable component others such as major depression do not. Other conditions such as bipolar disorder and anorexia nervosa have intermediate values. Often environmental factors are triggers or reinforce existing conditions. There seems to be a correlation between schizophrenia and urban living.

Basic Parts Of A Computer For Kids

Some of the main parts of a computer are the keyboard, CPU, monitor, power supply, and storage memory. Computers have become an indispensable part of our daily lives due to their high usability. From basic arithmetic operations to high-end algorithms, computers can perform multiple tasks based on the input data and software installed. The basic knowledge about the main parts of the computer is being imparted to school kids so they can learn the advanced concepts easily in the higher grades. There are five basic parts of a computer including the processor, which are assembled for carrying out various logical computing operations.

Psu: Power Supply Unit

Will brain-computer interfaces transform human lives? | Inside Story

A power supply mounts inside the computer case. This converts the AC mains supply from the wall socket and supplies the correct DC voltages to all the components inside the computer.

A computer power supply supplies the following voltages:

  • +3.3v: This voltage is supplied to the motherboard.
  • +5V: This voltage is supplied to the motherboard and other internal components.
  • +12V: This voltage is supplied to the motherboard and other internal components.
  • -12V: This voltage is supplied to the motherboard.

You get different wattage ratings for power supplies. The higher the wattage, the higher the electrical current that can be made available to parts that need it.

The higher you go in Watts, the more the power supply will be likely to cost.

A power supply also comes with its own cooling fan. This helps all the internal components to stay cool when the power supply is subjected to bigger loads.

If you would like to know more about a power supply and its lifespan, I have discussing it more in-depth.

Occipital Lobe And Parietal Lobe

The occipital lobe and parietal lobe in the human brain are similar to the GPU in a computer.

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

The parietal lobe processes sensory information such as touch, taste, and temperature and helps coordinate spatial relations.

The occipital lobe and parietal lobe of the computer is the GPU, where image, video, and 3D processing occurs.

A GPU can be present on a video card , embedded on the motherboard, or embedded on the CPU die .

Bcis That Use Activity Recorded Within The Brain

Hochberg et al are continuing clinical trials using a 96-electrode microarray implanted in the right precentral gyrus of patients with tetraplegia . These trials have demonstrated control of a robotic arm, computer cursor, lights, and television, using imagined arm movements. They have recently demonstrated that accurate cursor control performance was still obtainable 1000 days after implantation. Current research is exploring the use of this system for the control of prosthetic limbs and brain-actuated FES of paralyzed muscles.

Which Of The Parts Of A Computer Actually Execute The Program Instructions

The part of the computer that executes the program instructions is the CPU .

It is the control center of the computer, and it takes the data from the input devices or operating system and converts it to information output. It is a complex device that is made up of two parts: the control unit and the arithmetic/logic unit.

The CPU refers to the storage device or from programs in RAM for getting instructions and data.

The storage will store the operating system , as well as other applications and files.

The control unit of the CPU uses electrical signals to tell the computer system to carry out stored program instructions.

The arithmetic/logic unit has the electronic circuitry that executes the arithmetic and logical operations. The CPU uses this unit to test for conditions before it sends out orders to other parts of the computer.

The process of executing instructions is done in a specific way. First, program instructions and data need to be placed into memory from an input drive.

This information can be stored on the hard disk, or it can be input from a device. This data gets placed into memory, and then the CPU performs four steps.

The control unit gets the instructions from the memory. Then it decodes the instructions and sends the data that is needed to the arithmetic/logic unit. This set of steps is called Instruction Time.

Next, the control unit tells the memory to release the results to an output device. This set of operations is called the machine cycle.

False Memory And Memory Implantation

Human Brain

As much as we can trust our brain in keeping the record of everything, it can go through specific alterations. Our memories, especially the episodic ones, are reconstructed and can be falsely stored. One pop culture representation of false memory we have seen is in the movie “Inception.” Tit revolves around going into someone’s subconscious and planting the idea or memory that was not there.

Progress in psychology has proven that memory implantation is indeed possible. With therapy, the memories can be manipulated, and new memories can be implanted. We see the phenomenon of memory implant going on in ‘Westworld where AIs are given false human memories to mask their reality and purpose.

What Are The Parts Of The Nervous System

The nervous system is made up of the central nervous system and the peripheral nervous system:

  • The brain and the spinal cord are the central nervous system.
  • The nerves that go through the whole body make up the peripheral nervous system.

The human brain is incredibly compact, weighing just 3 pounds. It has many folds and grooves, though. These give it the added surface area needed for storing the body’s important information.

The spinal cord is a long bundle of nerve tissue about 18 inches long and 1/2-inch thick. It extends from the lower part of the brain down through spine. Along the way, nerves branch out to the entire body.

Both the brain and the spinal cord are protected by bone: the brain by the bones of the skull, and the spinal cord by a set of ring-shaped bones called vertebrae. They’re both cushioned by layers of membranes called meninges and a special fluid called cerebrospinal fluid. This fluid helps protect the nerve tissue, keep it healthy, and remove waste products.

Show/hide Words To Know

Blood-brain barrier: a protective layer that surrounds the brain and controls what things can move into the area around the brain.

What Is A Computer

A computer is a machine or an electronic device that stores, retrieves, and manipulates data. It can perform arithmetic operations or logical functions automatically based on the instructions and input data provided by users. Here, input data refers to the information provided by the users. The input data can be numbers or words, and the instructions refer to the codes or programs.

You may say that computers can carry out various logical and arithmetic operations like a human brain. However, a computer is capable of processing a huge amount of data, accurately in a very short time. Computers are used for many purposes, so now, lessons on the main parts of computers are introduced in the curriculum of school-level academics. We use computers to keep various records, send emails, pay bills, watch movies, write notes, play games, shop online, and for numerous other purposes. With the help of the internet, the network linking computers all across the globe, we can access information on any and every subject and issue.

Role Of Memory Retention In Daily Tasks

Memory building has a high range of involvement in doing the tasks of daily life. It is mostly dependent on short-termed memory. Ever walked into the room and forget why you came in? Ever forget what were you writing and question you were on during an exam? It has happened when short term memory is not built, and we lose the sense of what we are doing for a while.

Most tasks are process, and we need to actively know and memorize what we are doing every step of the way. How and what you are doing is also important. Thus, things go on in a constant loop. If you do not have short term memory, everything around you will be a giant blur of nothingness. Without short term memory, you will not be able to make long term memories.

What Is Inside The Cpu

At the hardware level, a CPU is an integrated circuit, also known as a chip. … At the top is a chip, then a logic circuit, then a logic gate, and then a transistor and wire. Some of those layers are physical devices, like the chip and transistors, and some of those layers are abstractions, like logic circuits and gates.
