Answer:
The Role of the Motherboard
The motherboard is lovingly named, because it is either the origin point of other parts of the computer or where every other component connects to. In a way, it is a lot like what you would refer to your home country as: the motherland.
The motherboard is basically a circuit board of a decent size, depending on the size of the computer we’re dealing with. It acts as a nexus of sorts because it facilitates the communication of the other components in the computer. There are ports on the motherboard that face the outside of the computer, allowing you to plug in different components into your computer and also to charge it.
Most motherboards also allow you to scale up by including slots that allow for expansion. You could add in components like CPUs and RAMs, Video cards, and so on. You can also expand the motherboard by adding more ports that allow you to connect even more auxiliary devices to your computer. In other words, you have control over just what your computer’s capabilities are.
The Power Supply
The power supply, as you might have already guessed is the powerhouse of the computer. It ensures that every other component gets the juice that it needs to function properly. The power supply looks like a black box of sorts, with a fan built into it. It is plugged into the motherboard, where it supplies power to the other components of the computer.
The fan on the power source plays a very important role. It cools it down as it does its duty to prevent the computer’s internals from overheating. It’s important to keep that fan clean so that the computer’s power supply functions like it’s meant to.
The Central Processing Unit
You may have heard that the central processing unit is the brain of the computer. The central processing unit_, or CPU, is where all the magic happens. It is to the computer what an engine is to a car.
The CPU mainly does arithmetic and logical tasks. It will make a bunch of calculations to ensure the functions of the computer are carried out efficiently. The CPU doesn’t always function at a single speed. The speed can vary depending on the priority and intensity of the task at hand. The CPU will generate a lot of heat as it does its work and so that fan that comes built into the power supply comes in real handy at this point.
The Random Access Memory
The Random Access Memory, or RAM, is a temporary form of memory. When you open an application in our computer, the computer will place that application and all its data in the RAM. When you close the application, then space in the RAM is freed. That is why your computer gets so slow when you have too many applications open; your RAM is probably being used at capacity.
Since RAM is only temporary, it has a volatile nature. The minute you turn your computer off, all of the memory that is stored in RAM is lost.
The more RAM you have, the greater the number of programs that you can run simultaneously.
The Hard Drive or Solid State Drive
Remember that we said RAM is volatile due to its temporary nature, which means the computer still needs a more permanent form of data storage. That’s why the hard drive or solid state drive exists. Traditionally, the hard drive is a drum with several platters piled on it and spinning, and physical arm then writes data onto these platters. These disks are very slow because of the mechanics through which data is stored, although latest hard drives, solid state drives, are much faster.
The Video Card
The video card is a dedicated component that hands the images output by your monitor display. They come with their own RAM, dedicated to this singular purpose. If your work involves highly visual work at very high definitions, then you should get yourself a video card to take the load off your RAM.
Sometimes, the computer may have integrated graphics, where some of the RAM is borrowed for graphics processing. This happens frequently on laptops, because there is a need to save space. Using integrated graphics is much less expensive using a graphics card, but is not sufficient for intense graphics functions.
The Optical Drives
These have become a lot less common today, with many machines doing away with them altogether. An optical drive is used to read CDs and DVDs, which can be used to listen to music or watch movies. They can also be used to install software, play games, or write new information into a disk.
Input/Output Devices
Depending on the type of computer you have, there are lots of devices you can connect to your computer to input information and also output it. Some examples of input devices are the mouse, the keyboard, and the webcam. Examples of output devices include monitors, speakers, and monitors. There are also removable devices, such as SD cards and flash drives, which can be used to transfer data to and from your computer.
