Peripheral
Peripherals are computer equipments that are necessary but non-essential, such as a printer, scanners, etc.
Backup
Backup refers to copying data or files to a different location as a precautionary measure against data loss or PC malfunction.
BIOS (Basic Input/Output System)
BIOS is the initial program that is executed when a PC is turned on and manages the data flow between the operating system and various devices such as the storage device (HDD, SSD, eMMC), video card adapter, keyboard, mouse, and printer.
Booting
Booting refers to turning on the PC. Using a storage device (HDD, SSD, eMMC), the booting process loads the operating system into the memory so that the PC can operate. Rebooting simply refers to reloading the operating system into the memory again. You can reboot the system by pressing Ctrl+Alt+ Delete.
CMOS (Complementary Metal-Oxide Semiconductor)
CMOS is a program stored in the ROM BIOS that is used to configure various hardware.
Cursor
Cursor shows the location where you can enter the text in the PC screen. Pointer is also a kind of cursor that can be moved by using a mouse or touchpad.
Download
Downloading is a process in which data on a remote PC is transferred to your PC. You can also download files from the Internet to your PC.
Driver
A driver is a program that mediates the communication between a software application and a specific device. For example, if you purchase a printer or monitor, you need to install the related driver(s) in your computer to use it.
Format
Formatting refers to designating the sectors and tracks on a hard disk so that the PC can write new data to the hard disk. Once you format your disk, all the data on the disk is lost. You must be sure to check your disk before formatting.
Hub
A hub is a device that collects data from one or more places and sends them to other place(s).
Operating System (OS)
Operating system is a program that is loaded onto the memory by the bootstrap program and manages other software programs loaded later.
Partition
The storage device (HDD, SSD, eMMC) can be divided into more than one logical partition when formatting. You can install different operating systems in each partition, or use partitions for separate file management or multi-user management. The storage device is generally divided into two partitions, called the C: hard drive. and D: drives respectively.
Safe Mode
Safe mode allows you to boot the system with minimal options so that you can diagnose any problems in your system. Most programs other than the operating system, as well as drivers for the mouse, keyboard, and VGA, are not loaded into memory.
Scroll Bar
A scroll bar is displayed on the bottom or right side of a window. You can use a scroll bar to move to an area that is not displayed in the window. Windows system provides scroll bars for horizontal and vertical movement.
Shortcut
Shortcut icons are used to access certain programs or tasks more conveniently than usual access methods. You can save time by using shortcuts.
Upgrade
Upgrade means changing the hardware or software of your PC to increase its performance.
Update
Update means changing the software or adding new functions.
Virus
A virus is a combination of commands that changes a software program or an executable file, and copies itself to other files and programs. Some viruses can erase important data on your storage device (HDD, SSD, eMMC).
Hot Key
Hot Key is a combination of keys that executes a certain command in the operating system or an application when pressed.
Local Area Network (LAN)
LAN refers to high speed network environments linking companies and households.
Wireless LAN
Wireless LAN is a local area network that does not use a cable for data transfer. Wireless LAN has developed together with portable PCs. Wireless LAN provides portability as the change in the location of a computer does not affect the structure of the LAN.
Trusted Platform Module (TPM)
Trusted Platform Module (TPM) provides hardware-level security to the system which is more powerful than the conventional ones. If combined with a security software, TPM enhances security for the overall system, files, email services and private data.
Fingerprint Reader
A fingerprint reader is a system that records fingerprints and uses them for user authentication. The fingerprint reader consists of various features that allow the user to enjoy enhanced performance of the Windows system.
CPU (Central Processing Unit)
CPU is the main processing unit that contains the logic circuit for processing the commands of a PC program.
Hard Disk (HDD)
A hard disk is an essential part of the PC. It is an auxiliary storage device that can store massive amounts of data by changing the magnetic properties of the disk surface. It allows random access to the stored data.
Solid State Drive (SSD)
SSD is a device that stores data using semiconductor. It is faster, smaller, and lighter than a hard disk.
LED (Light-Emitting Diode)
LED is a kind of diode that emits light when electricity flows through it. LED is used in various signaling lamps, such as the LED of a storage device (HDD, SSD, eMMC) that blinks when the disk is being accessed.
RAM (Random Access Memory)
RAM is a temporary storage device that contains the operating system and any actively running applications so that the CPU can access the data more quickly. The data stored in RAM is maintained only when the PC is turned on. Once the computer is turned off, the data stored in RAM disappears and should be reloaded when the computer is turned on again.
SD Memory Card
SD memory card is a memory card based on flash memory. It is used as a storage device in various digital products including smartphones, laptops, and digital cameras. It is classified into standard, mini, and micro SD memory cards depending on its size.
Tablet
Tablet is a kind of input device which you can directly write on the screen with a stylus pen. This pen can be used to perform a mouse function.
Tablet Stylus
It is a pen provided together with the tablet PC. You can use it to write text or draw a picture on the tablet screen or use it as a mouse.
Tablet PC Input Panel
It is a program used in a tablet PC. In this program, you can use a stylus, sound, and screen keyboard to enter text, symbols, numbers and shortcut keys. You can use this input panel to communicate with Windows-based programs.
Bluetooth
Bluetooth allows wireless communication between portable devices such as a notebook PC, mobile phone, headset and printer.
HDMI (High Definition Multimedia Interface)
HDMI is a digital video/audio standard that allows you to send and receive both high-quality video and audio with one cable.
USB (Universal Serial Bus)
USB is a standard for connecting the PC to peripheral devices such as keyboard, mouse, and portable memory/hard disks.
Resolution
Resolution indicates how many pixels an image is composed of. Higher the resolution, sharper the image.
Browser
Browser means the software like Microsoft Edge that allows you to surf the Internet on your PC.
