Computer Parts

Posted on

            Most computers contain several key components including: A Graphics Processing Unit (GPU), A motherboard (or MoBo), A CPU (Central Processing Unit), Some RAM (Random Access Memory), A Hard Disk Drive (HDD) A chipset (Basic Integrated operating system or BIOS), and A Power Supply Unit (or PSU).  All these parts come together to form a complete computer now of course there are some other parts that can be added like expansion cards, extra ram or hard drives, but for the most part those are the main parts.  Now lets go over each one individualy: 

            The Motherboard is the main part of a computer like the home base.  it brings all the parts of a computer together and connects them electrically.  It holds everything except the power supply and hard drive(s).  The motherboard also constains the chipset which is a tiny storage device chich conatins a BIOS(basic integrated operating system) that allows you to control the computer without a hard drive and also allows you to perform functions like overlcokcing the CPU and Graphics card, Aswell as configuring a new operating system.                                   Image

            Next is the CPU, the CPU is the brain of any computer.  A CPU consists of over a 100 billion transistors operating with a 1 or 0 binary code.  The CPU makes all the calculations that go on inside a computer.Image

            Now there is the RAM (Random Access Memory) RAM is used as temporary solid storage while a program is running to store temporary files concerning the project.  The more Gigabytes of RAM you have the more programs you can run at once.  RAM clears itself when the program is shut down but it is completely wiped when you shut off your computer to clear the OS (Operating System) files off. Image

             Next, there is the ALMIGHTY GRAPHICS CARD!  The graphics card is the piece of hardware that displays pixels and movement on your desktop or in a game. The better the graphics card you have the more graphical capability you have.  Some graphics cards can go from under $50 to over $3000 depending on the amount of graphic cores and amount of GDDR5 Video RAM.

            Now, there is the hard drive, a hard drive is the main source of storgae for a computer as the RAM is wiped every time there is no power.  The most common type of hard drive is the HDD or hard “disk” drive.  The disk drive had a disk that spins at 7200 RPMs standard.  The newer type of hard drive that is becoming more and more popular is the SSD, which uses conductor chips instead of magnetic disks.  This type of hard drive is very hard to break unlike the HDD which can break from a small drop.  SSD’s also has a much faster Data transfer rate when compared to a standard HDD.

              Next is the PSU (Power Supply Unit) this is piece of hardware that powers all the parts of a computer.  It has many different electrical components inside including transistors and a small ICB (Integrated Circuit Board) to hold everything together.  Most PSUs have a fan for cooling the transistors and ICB that is on the top of the box.  The final component of a PSU is the wire harness, which comes out the side and has tons of different connectors for each piece of hardware.

              Finally, we have expansion cards that might add more of a type of port or more slots for RAM chips or graphics cards.  The one below is a expansion card which adds more of the new USB 3.0 via a PCI Express mini slot on the motherboard.

            Now to round up I will show you the back of a computer with labeled ports so you know which ports are which.  I hope you enjoyed learning what different parts of computers do.Image
