With the rapid advancement of technology, connecting a computer or laptop to a TV or projector is no longer unfamiliar. Using HDMI cables with devices that support the HDMI port standard allows you to connect your laptop to a TV to enjoy videos, including sound on the computer screen instead of the small laptop screen as before.
Connecting your computer to external devices such as a Mouse, keyboard, USB, network port, etc., helps you create the perfect computer with all the accessories needed for work and study. In this article, Mytour will guide you on how to connect your computer to external devices.
Guidance on connecting your computer to external devices
Computer power interface port
This type of port is constructed with one end plugged into the 220V power source, consisting of 2 pins, while the other end is plugged into the computer power source with 3 pins. This is a specialized communication port providing electrical energy for the entire computer system.
PS/2 standard keyboard and mouse interface port
The Violet-colored port is designed for connecting a round-headed (PS/2) Keyboard, while the Green-colored port is intended for connecting a round-headed (PS/2) Mouse. When plugging into the Mainboard, careful observation is required to ensure the correct orientation and prevent bending or breaking the plug pins. Its primary function is to smoothly execute click, select, and typing operations.
USB standard peripheral device interface port
This is a highly versatile port as it can be used to connect a mouse, keyboard, scanner, portable storage device, etc., with the quantity depending on the Mainboard configuration, but mainly 3 or 5 slots on one Mainboard.
Parallel interface port (parallel port)
This type of connection port is used for printers, scanners, but with newer machine models, this type of port is no longer integrated on the Mainboard. Instead, it is replaced by the standard USB connection port.
Firewire interface port
This type of port is commonly used for connecting cameras, mobile devices, but only some types of Mainboards still use this.
Internal network interface port (Ethernet, LAN)
The current type of port is structured with two identical ends with 8 pins each. One end goes into the Modem ADSL, Router, and the other end goes into the Mainboard with the task of transmitting data to access the Internet.
Audio peripheral device interface port
The main purpose of this type of interface port is to transmit audio data to devices with the following functionalities:
- The green-colored port transmits audio out - connects to speakers or headphones.
- The pink-colored port transmits external audio in - connects to a microphone.
- The sky blue-colored port is used to capture audio signals from external devices into the computer, but with this type of port, it is usually removed from the Mainboard.
VGA standard monitor interface port
This type of port is commonly used to connect with a monitor to display information.
DVI standard monitor interface port
This type of port is typically used to connect with devices using DVI interfaces such as LCD monitors, projectors, and other supporting devices.
Above are the connection ports for peripherals that we commonly see and use with our computers. Through this article, you can gain a better understanding and apply these on your own computer.
