Computer
A computer is a machine that automatically performs complex calculations according to a given procedure. In particular, digital data can be continuously input/output, calculated, converted, etc.
Using an electronic circuit or the like, and can be used for various purposes by being described and given by a human being or the like in detail.
Historically, there were mechanical automatic computers that manually drive gears, etc., but in modern times, machines called computers are generally semiconductor integrated circuits (IC chips) such as microprocessors (CPU / MPU) and semiconductor memories.
It refers to the one that executes computer programs (software) such as the operating system (OS) and application software recorded in the storage device.
Computer Classification
Devices that are generally considered to be computers include "personal computers" (PCs), which are general-purpose computers for individuals, and large-scale, high-performance computers used in information systems such as companies and government offices. A "server" (server) or “mainframe " (mainframe computer), used to such as scientific computing is an ultra-high-performance computer " supercomputer " (supercomputer), and the like.
In addition, many modern electric devices have a small computer a system built in the device for controlling the internal device and are called an " embedded system ".Devices equipped with such embedded computers include mobile phones/smartphones and tablet terminals, video game consoles, communication devices, and network devices, television receivers, video recorders, digital cameras, electronically controlled home appliances, and industrial machines. There are transportation machines and so on.
Computer Configuration
General computers include “control devices " that control the execution status of programs and the state of each device,” arithmetic devices " that calculate and process data,.
It consists of an “input device " and an “output device ”that exchanges information with the outside world. These five elements are sometimes called” five major devices of a computer ” (five major functions ).
Of these, control devices and arithmetic units are often integrated as a single device or semiconductor chip in modern times, and this is called a "processing unit" (PU). The central processing unit that controls the entire computer system is called the "Central Processing Unit" (CPU).
The storage device is a "main storage device" (main memory) used for the temporary storage of programs and data required for immediate operation, and an "external storage device" (storage) or "auxiliary storage device" used for permanent recording. It is often divided into.
The calculation procedure is a method of recording a sequence of instructions to the CPU as data in a storage device, reading it in order, and executing it ( stored-program method ), and this is called a "computer program" or simply a program.
Computer Parts
General parts and minor parts for intermediate and advanced players are introduced separately. When purchasing a BTO personal computer, it is sufficient to have knowledge of only general parts.
If you want to know more, please read the parts for intermediate and advanced users.
CPU
The CPU is a part that processes information on a personal computer. Abbreviation for Central Processing Unit, which can be translated as a central processing unit. It plays an important role in every situation such as browsing the Internet with a browser, watching videos, using Excel, and playing games.
SSD
SSDs are next-generation storage. Abbreviation for Solid State Drive. It can write and read faster than the HDD introduced below. In addition, quietness is also attracting a lot of attention. However, it also has the disadvantage of being more expensive than HDD. It's a good idea to balance it with your budget.
Graphic board
The graphic board has the role of displaying the image on the monitor. Sometimes called a GPU or video card. The GPU may be installed inside the CPU. When playing 3D games, you need an external high-performance graphics board.
Storage
It summarizes the storage of the personal computer. There are two main types of storage, SSD, and HDD. Some BTO PCs also have a dual-storage model that uses both storages. It is popular because you can take advantage of both.
HDD
HDD is a large-capacity storage device. Abbreviation for Hard Disk Drives. Until now, storage has always been HDD. It is very cheap and easy to realize large capacity storage. Due to its low price, it is still the mainstream storage among BTO personal computers. However, it is also a fact that the merit of choosing SSD is gradually disappearing because the price of SSD is decreasing.
eMMC
eMMC is storage that uses flash memory. Its compact size and low power consumption make it attractive, and it is often used mainly in mobile notebooks and smartphones. 32GB or 64GB is common and few models are larger.
Motherboard
A motherboard is a printed circuit board for mounting various parts such as CPU, graphic board, power supply, and peripheral devices. It's easy to understand if you think of the PC parts being integrated on the motherboard. There is a standard on the motherboard, and you need to use parts that meet that standard. Like the other parts, the motherboard is evolving.
Memory is hardware that can temporarily or permanently store various data necessary for using a personal computer. By temporarily saving the data that is mainly taken out from SSD or HDD, the CPU can process the data smoothly.
Work efficiency can be improved by creating a relay point without collecting information directly from SSD.
GPU memory (VRAM)
GPU memory is a part that temporarily stores image information. It is easy to understand if you think of it as a type specialized for the above system memory (memory) graphics.
It requires a lot of GPU memory for gameplay at 4K resolution and building large 3D CAD models. However, the general public, such as playing games in Full HD or using Photoshop, should not be so conscious.
Power Supply Unit
The power supply unit is an important part that supplies electricity to the entire personal computer (CPU, etc.).
However, you don't have to think about a special power supply unit when you buy a BTO computer. This is because it has a power supply unit that is ideal for running a personal computer.
In many cases, a general BTO personal computer is equipped with a power supply unit of about 300W to 500W, and a gaming PC or a model for creators is equipped with a power supply unit of about 500W to 800W.
In addition, using a power supply unit with good power efficiencies such as 80PLUS GOLD or 80PLUS PLATINUM has the effect of extending the life of personal computers and parts.
Optical Drive
An optical drive is a device that can read and write CDs (CD-Rs), DVDs, CDs, etc. For example, you can read a CD disc to install the software needed to start the printer.
Recently, as the need for optical drives has diminished, more models are not equipped by default. Nevertheless, it is possible to install an optical drive as an option, or it is possible to support it with an external drive.
