A Guide to the Various Computer Parts and Knowing Which to Get for What

You recently got a laptop, and it’s working great; however, one day, it suddenly started malfunctioning, and you don’t know why. You tried to check every nook and cranny, but you aren’t an expert in this field. You hardly knew what that giant chip looking part did or what the disc object functioned as; you’re completely lost.

Of course, if you want to buy computer parts online or in a physical store to replace something that isn’t functioning properly anymore, you first need to understand what each part does and, most especially, what each part is called. You could waste a lot of money if you muttered the wrong part to the store clerk when looking for something else.

Below is a quick overview of the most common computer parts and what they serve. Hopefully, they help you sort things out.

  1. Motherboard

Just like the name implies, the motherboard is the mother of the whole machine because it’s the one that connects every part, basically like the heart of the computer. It helps regulate the power connected to all the other ports like the hard drive or the system memory from the power supply itself. It serves as a bridge that connects all the parts and enables them to function individually and together.

  • Central Processing Unit (CPU)

If the motherboard is the heart, then this part is the brain. Similarly, like the human brain, it’s the one that calculates every function in the computer and sees to it that each calculation is perfect and that the computer can handle it. The better the CPU, the better the performance of the computer.

  • Power Supply

Of course, the computer wouldn’t be able to function at all unless it’s plugged in and powered by something. The power supply serves as the source of electricity and power, which connects the motherboard to the other parts of the computer enabling each part to function at its finest.

  • Optical Drives

Not all laptops or computers are the same, so not all of them have optical drives installed within them. Despite not being readily available to every unit or PC, since installing software has evolved and everything is digital now, it’s still important to note what it is or was used for.

  • Random Access Memory (RAM)

Just like everything else in this world, RAM is temporary (just kidding :D). It is a temporary means of storage that the unit has. If ever a certain software is opened, the data is being placed in the RAM portion of your unit, and when you close that software, the RAM then lets go of it. It’s important to also take note of how much RAM your unit has, especially if you’re using it for something heavy like live streaming or online gaming.

  • Hard Disk Drive/Solid-State Drive (HDD/SSD)

If the RAM serves as temporary storage for your data, these parts serve as permanent storage spaces. Hard drives are traditional means of storing data where the arm part of it jots down the data to the disk physically. However, nowadays, people prefer solid-state drives as they are newer and faster than the old hard drives. However, some people use both for these units, but that is unnecessary as one type is enough.

  • Video Card

Like all the other parts, this part is important as it is in charge of the images being displayed on the monitor. If you’re the type of person who values graphics and the overall looks of certain software or games, then you should choose the best video card. It has its RAM that helps with these functions and makes sure that the graphics are top tier.

  • Input and Output Device

Just like how other people are, computer units also need accessories to function. Input devices like a mouse, laptop touchpads, keyboards and output devices like monitors and printers all have their functionality and are equally essential as with all the other parts previously mentioned.

Of course, getting a laptop or pc can be exciting, and at times you got it because it looked cool or that it had great specs. But learning how each part works is essential when a part breaks, and you need to buy computer parts online or in a physical store to replace them. Learning the proper terms and uses of each part would greatly benefit you in the long run and help you if any problem arises.
