ELECTRONICS MECHANIC - CITS

• USB supports data transfer, power supply, and various communication protocols.
• Different USB versions include USB 1.0, USB 2.0, USB 3.0, USB 3.1, and USB 3.2, with each version offering
improved data transfer speeds and power delivery capabilities.
3 RGB (Red, Green, Blue)
• RGB is a color model commonly used in digital displays and image processing.

• In the context of interfaces, RGB refers to connections used to transmit analog video signals, typically via
separate red, green, and blue cables.
• RGB connections are commonly found in older TVs, monitors, and video game consoles, providing analog
video output.
4 VGA (Video Graphics Array)
• VGA is an analog video interface commonly used for connecting computers, laptops, and projectors to display
devices.
• VGA cables typically have 15 pins arranged in three rows and transmit analog RGB video signals.
5 DVI (Digital Visual Interface)

• DVI is a digital interface used for transmitting video signals between devices, such as computers, monitors,
and projectors.
• DVI cables can carry both analog and digital video signals, depending on the type of connector (DVI-I, DVI-D,
or DVI-A).
• While DVI is still used in some devices, it has largely been replaced by HDMI and DisplayPort in newer
products.
6 DisplayPort
• DisplayPort is a digital interface primarily used for connecting computers, laptops, and monitors.
• DisplayPort supports high-resolution video and audio, as well as features like multi-stream transport and
daisy-chaining multiple monitors.
• DisplayPort cables and connectors come in various versions, with each version offering increased bandwidth
and additional features.
7 Thunderbolt
• Thunderbolt is an interface developed by Intel that combines PCI Express and DisplayPort into a single
connection.
• Thunderbolt supports high-speed data transfer, video output, and power delivery over a single cable.
• Thunderbolt cables and connectors are commonly used in Apple devices and high-end PCs for connecting
peripherals like external storage drives, displays, and docking stations.
TV Remote Controls
Types of TV Remote Controls
1 Infrared (IR) Remote Control

• Most traditional TV remote controls use infrared technology to transmit signals to the TV.
• IR remotes require a direct line of sight between the remote and the TV for communication.
2 Radio Frequency (RF) Remote Control
• RF remote controls use radio frequency signals instead of infrared.
• RF remotes don’t require a direct line of sight and can work through walls and obstacles.

3 Bluetooth Remote Control
• Bluetooth remote controls connect to the TV via Bluetooth wireless technology.
