Computers are electronic devices that can be used to complete office activities, play games, and other activities. As technology develops, computers are increasingly diverse and sophisticated.
Currently, computers are divided into 2 types, namely portable and desktop. Types of portable computers such as laptops, tablet PCs, netbooks, and the like. While the desktop is a type of computer that first existed, but the function remains the same.
This article will specifically review the function of each component on a desktop computer. The following components on a desktop computer:
1. Casing (case)
Desktop type computers generally have a case as a “home”. The case is made of plastic and metal. However, as technology develops, some desktop computers have been designed to be more compact without a case. Designs like this are often found on AIO PCs, where the computer case is made to blend with the monitor screen. The function of the casing is to protect computer components from dust and dirt.
2. Power supply unit
PSU is a vital component in desktop computers, because it is in charge of converting AC current into DC current, so that computer components get a power source.
Not only the CPU, the motherboard is also a vital component in a desktop type computer. The motherboard is a circuit board that connects all computer components, from the CPU, RAM, ports and expansion slots, and many others.
The main component that is integrated with the motherboard is the CPU, or better known as the brain of the computer. Because, the CPU is in charge of doing calculations and executing every command from the user. CPU components are equipped with heatsinks and fans to reduce overheating. The latest desktop computers are usually also equipped with a water cooling system and GPU.
The fifth component in a desktop computer is the chipset. Just like RAM, this component serves as a communication link between the CPU and other components.
This component is not only a communication link between computer components, but is also in charge of storing various types of data. Computers that have large RAM, the storage capacity is also more, and is not easy to slow down.
7. GPU/graphics card
This component is in charge of carrying out user commands related to the graphical process. For gamers, animators, designers usually not only need an internal GPU, but also need a dedicated GPU with a larger size.
ROM or Read Only Memory is where the BIOS firmware and settings are stored. However, BIOS is generally used on older computers, because the majority of modern computers use UEFI.
9. CMOS battery
This component is in charge of providing power to the BIOS, so that the BIOS settings and date are not lost, and the computer continues to run.
10. Hard disk
All data and the operating system will be stored on the hard disk. However, hard drives are not popularly used on portable computers, SSDs are more widely used in portable computers. SSDs have faster read and write speeds than HDDs, besides that SSD power usage is also more efficient.
Well, this one component must be known to everyone, because this component is in charge of displaying graphics in collaboration with the graphics card. Along with the development of technology, more and more monitor forms, even today touchscreen monitors are very popular.
Those are some important components of a desktop computer. Actually the components in a portable computer are also not much different, it’s just that they are packaged more concisely and more sophisticatedly.
