VGA connector facts for kids
A VGA connector is a special kind of plug used with computers. It helps send video information from your computer to a screen, like a TV or a computer monitor. Think of it as a messenger that carries picture signals.
Most VGA connectors have 15 small pins, arranged in three rows of five. Some rare ones might have 18 pins. Today, newer devices often use digital plugs like HDMI, which send clearer signals.

What is a VGA Connector?
A VGA connector is a type of computer plug that sends analog video signals. This means it sends information as a continuous wave, like old radio signals. It connects your computer to display devices such as television screens or computer monitors.
How Does a VGA Connector Work?
When you plug a VGA cable into your computer and monitor, it creates a connection. The computer sends video data through the cable to the monitor. The monitor then uses this data to show you images and videos. It's like a direct line for pictures.
Pins and Their Purpose
Most VGA connectors have 15 pins. These pins are arranged in three rows, with five pins in each row. Each pin has a specific job, like carrying red, green, or blue color information, or telling the screen when to refresh. Some less common VGA connectors have 18 pins.
VGA vs. Modern Connections
VGA connectors were very common for many years. However, in the 21st century, technology has moved towards digital connections.
Why Digital is Better
Newer devices mostly use digital plugs, like HDMI or DisplayPort. Digital signals send information as ones and zeros, which is less likely to get interference. This means digital connections usually give you a sharper and clearer picture than analog VGA connections. Digital cables can also carry sound, which VGA cables cannot.
